Incorruptible: Why Good Companies Go Bad... and How Great Companies Stay Great

by Eric Ries

"Indispensable!" —Kim Scott, New York Times bestselling author of Radical Candor

“Ries shows us, with rigor and optimism, how to build organizations that are worthy of our trust.” —Frances Frei, Harvard Business School

"A playbook to help avoid the inevitable pitfalls and find your path to the business you set out to create.” —Mark Cuban, entrepreneur and investor

What if the most radical idea in business is that purpose is the best tool for unlocking long-term growth? And what if the secret to sustaining your organization's integrity is readily available if we look in the right places?

The Lean Startup transformed the way a generation of entrepreneurs built products, sparking a global movement for smarter, faster innovation. Now with Incorruptible, Eric Ries delivers "the book I wish I'd had while building" (Leah Busque, founder of TaskRabbit), and takes the next step by answering a deeper how can we build companies that stay true to their mission even after they become successful?

In Incorruptible, Ries reveals the hidden forces that cause even great organizations to drift from their original reason for being. Then he shows how to design businesses that can withstand that pressure. Drawing on two decades of work with founders, CEOs, and investors, he exposes the flaws that make companies vulnerable to short-term thinking. He offers a blueprint for "mission-controlled" organizations that can grow, prosper, and endure without losing their soul.

Using lessons from generations-old retailers and manufacturers to recently founded tech sector stars, Incorruptible reframes the ethical longevity of business as a practical design problem. It gives every builder—founder, executive, investor, or citizen—"a playbook to help avoid the inevitable pitfalls" (Mark Cuban, entrepreneur and investor) and the tools to create enterprises that uplift rather than exploit.

Success alone will not protect what matters most. Only incorruptible design can. "For any founder who truly wants to make a difference, this is a must read" (Vlada Bortnik, founder and CEO of Marco Polo).

We’ve all heard the stories of founders being voted out of their companies…and those companies moving far away from their founders’ original missions. When short -term ROI supercedes utility and positive, transformative change, we all suffer. In the words of. Corey Doctorow, it’s #Enshitification, [btw a great book] and it’s all around us.
Eric Ríes has seen this firsthand, and has been wrestling with alternative approaches that aim to help companies remain mission-driven in the face of pressure from investors just looking for a quick exit. In this work of non-fiction, he profiles a number of companies that have managed to stay true to their causes, not always easily: Patagonia, CloudFlare, Novo Nordisk, and Anthropic to name a few. Ríes walks us through all the arguments for building an unassailable mission-driven organizational structure. Several times we hear about founders whose lawyers said “it’s too early” to put such a structure in place then later told the same founder “it’s too late for that.”
Most importantly, Ries illustrates that it is possible (and, of course, preferable) for people to build thriving companies (like Costco and its predecessors) that contribute in a positive way to their communities, support their partner-suppliers, respect their employees, and delight their customers.
The quarterly earnings report isn’t the be-all and end-all of running a successful business and, in fact, is to blame for a lot of what ails our corporations today. If only we could all work for companies that align with our personal values and that put their mission above short term gains.
This is an inspiring book, narrated by the author. There is a companion PDF with additional data, plus audiobook extras - interview snippets from Ries’ podcasts with three founders talking about their experiences implementing their “incorruptible” business structures.
My thanks to the author, publisher, @S&SAudio, and #NetGalley for early access to the audiobook of #Incorruptible for review purposes. Publication date: 26 May 2026.

The Architecture of a Promise
Eric Ries’s “Incorruptible” asks whether companies can build structures strong enough to protect the values that made them worth building.
By Demetris Papadimitropoulos | May 1st, 2026


“After the Vote” – a solitary boardroom at dusk for Eric Ries’s “Incorruptible,” where the promise of a company sits beneath cold blue light, waiting to learn whether power will protect it or sell it.

In most business books, governance is the windowless beige room one enters after the exciting work is done: charters, boards, voting rights, compliance documents, lawyers speaking in the soft baritone of risk management. “Incorruptible” begins from the opposite suspicion. For Eric Ries, governance is not the dull casing around a company’s living compact. It is the arrangement of power that decides whether that compact gets load-bearing walls or remains a polished sentence in search of enforcement.

The voltage is higher than the subtitle lets on. “Why Good Companies Go Bad… and How Great Companies Stay Great” sounds like the sort of management diagnosis that might lead to a quadrant, a laminated framework, and a closing chapter in which every reader is invited to become an “intentional leader” by Tuesday. Ries has built a stranger apparatus: founder’s mea culpa, governance manual, critique of shareholder primacy, and reform manifesto with implementation tabs. By the end, it has also become myth. This is a book about boards and charters that finds its way to a queen of the dead with a golden scythe. One does not often encounter corporate law wearing a cloak. Stranger still, it fits.

The opening stages the structural trap before it explains it. Ries receives a call from “The Professor,” a scientist-founder whose AI biology company could design life-saving medicines but also targeted poisons, bioweapons, or a plague no one is prepared to meet. The Professor does not merely fear failure. He fears success under the wrong structure. What happens when investors want faster returns? What happens if a board replaces him? What happens if a company built to heal becomes a machine for harm, and its founder wakes as a monster with excellent liquidity and no sleep? Ries takes the call while parked outside what appears to be a celebration for another founder, only to reveal that the event is really a wake. The founder has been forced out; the company remains, but not in the form people loved. Its name lives on. Its animating compact has gone into receivership.

That scene gives “Incorruptible” its hinge. A company can be legally alive and spiritually dead; the stock may trade, the logo may shine, the mission page may still hum its little hymn, but the thing that earned devotion has been professionally removed. Ries’s subject is not corporate misconduct in the tabloid sense. It is the slower betrayal of watching something trusted become a polished instrument for betraying the trust that made it valuable.

From that wound, Ries builds his argument. “The Lean Startup,” his earlier book, taught a generation how to test, learn, build, and scale. “Incorruptible” is his attempt to answer the question success left behind: once you have built something worth protecting, how do you keep its value from attracting the forces that will strip it for parts? His answer is structural. Good companies do not usually go bad because everyone inside them rises one morning, stretches, and chooses villainy before breakfast. They go bad because ownership, incentives, boards, metrics, charters, career rewards, and sanctified “best practices” teach decent people to call surrender prudence. Ries names that pull “financial gravity,” and the phrase earns its keep. It gives a body to the force that makes short-term extraction feel inevitable even to those who dislike its consequences.

Ries does not confuse profit with guilt, which keeps the book from becoming a sermon with spreadsheets. His claim is more exacting: not every way of making money is equally good. Some profit is the residue of value created; some is value captured, deferred, externalized, disguised, or harvested from the loyalty that made the enterprise possible. “Incorruptible” presses against the well-compensated shrug of “that’s just business.” The shrug, Ries suggests, is not wisdom. It is often the sound a system makes when too many people have learned how to benefit from having no alternative.

The structure is not scaffolding after the fact; it is one of the book’s arguments. Part I, “The Shape of the Abyss,” diagnoses how mission-driven companies become open to capture. Part II, “Escape Velocity,” turns toward counterweights: mission drive, constitutional governance, aligned ownership, public-benefit structures, steward ownership, and the wonderfully odd “spiritual holding company,” a separate entity meant to preserve an organization’s animating purpose over time. Part III, “To Bend the Light,” widens from company design to standards, supply chains, mission transmission, and civic infrastructure. The physics metaphor is not decorative. Gravity pulls. Structures brace. Escape takes force. The most durable institutions do not merely survive the field; they alter the field around them.

The examples arrive in force, but the best of them behave less like exhibits than autopsies: Sol Price and FedMart, Costco, Patagonia, Whole Foods, Boeing, Johnson & Johnson, Google, GitLab, Mondragon, Anthropic, Grundfos, Novo Nordisk, Tony’s Chocolonely, Underwriters Laboratories, Cost Plus Drugs, Pol.is, and the Long-Term Stock Exchange itself. The danger of such breadth is the overstuffed-briefcase problem: too many files, all relevant, none breathing. Ries mostly avoids that fate because the examples keep returning to the same uncomfortable test. What happens when culture has no enforcement? When metrics become idols? When governance experts mistake mission protection for managerial entrenchment? When a company’s purpose has no legal or economic machinery behind it?

The more revealing neighbors are not ordinary startup manuals but books that ask what lets institutions endure without forfeiting their reason for existing. “Incorruptible” sits near Lynn A. Stout’s “The Shareholder Value Myth” in its challenge to the supposed inevitability of shareholder primacy, near Jim Collins and Jerry I. Porras’s “Built to Last” in its fascination with durable companies, and near Yvon Chouinard’s “Let My People Go Surfing” in its belief that a company’s commitments should govern daily operations rather than decorate recruiting copy. Ries’s distinctiveness lies in the severity of his structural demand. Mission statements, founder charisma, beloved cultures, values posters, all-hands speeches – none of these are enough. They may inspire, but inspiration is not a control right. At some point, someone will ask who can vote, who can sell, who can replace whom, who controls the board, which metric counts, and what the charter actually says when the room gets expensive.

Ries writes better than the governance shelf requires. His prose gives abstractions a body: earbuds pressed against traffic noise, music rattling a windshield, a party turning into a wake, a company fed into a meat grinder, a leader on cool bathroom tile at 3:15 a.m. after refusing to compromise the Long-Term Stock Exchange. The bathroom floor is not rhetorical furniture. It punctures the usual founder-hero posture and lets failure, humiliation, and resolve occupy the same square of tile. A less candid book would have converted the scene into triumph with better lighting. Ries lets it remain a collapse first, then a lesson.

The diction keeps unlikely company: fiduciary duty beside human flourishing, cap tables beside souls, standards beside mercy, boards beside monsters. Sometimes the furniture bumps. The finger-on-the-table second person can begin telling readers what they have seen, felt, and must now recognize with a little too much certainty. For some, that insistence will be bracing. Others may feel trapped at a reception by a brilliant, wounded founder who has located the moral center of capitalism just as the hors d’oeuvres run out. Yet the heat is not fake. Ries is trying to make institutional betrayal impossible to treat as background weather.

The book’s sharpest work is to drag mission out of the brochure and into the machinery. It refuses to leave purpose in the handsome-type portion of corporate life, the part quietly ignored when the board packet arrives. Ries asks what mission means when the founder leaves, when the company goes public, when investors want liquidity, when lawyers advise obedience to norms that have been misnamed prudence, when employees are told to trust what has never been protected, and when customers cannot see the machinery rearranging their relationship to the company. This is where “Incorruptible” becomes more than a plea for nicer capitalism. It is a design argument: if values matter, they need mechanisms; if trust matters, it needs a container; if a company’s purpose is real, it should survive the quarterly weather.

Beneath the grammar of power, the book is about grief. Not the public grief of scandal, but the quieter grief of recognition: the beloved product worsened after loyalty has been captured; the workplace that once had a compact with its people turned extractive, polished, and very well-advised; the platform that learned to tax the attention it first earned; the company whose founding promise survives only as a museum label. Ries understands that people do not mourn companies because they confuse corporations with friends. They mourn because their work, taste, time, trust, and hope have been deposited there. When the institution turns, something personal has been used without consent.

The cost of the wager is also clear. “Incorruptible” is a thrilling title and a dangerous one. Ries is persuasive when he shows that structure can make betrayal harder, mission more durable, and trust less available for extraction. He is less persuasive when the rhetoric edges toward the idea that design can make corruption impossible. No governance form abolishes vanity, cowardice, exhaustion, fear, status hunger, or the human gift for routing around constraint while praising the constraint in public. The book knows this in flashes. Its epilogue admits that its tools can be used “in reverse,” as instruments of career advancement, fluent takedown, or sharper complicity. Still, the title’s absolutism sometimes shines more brightly than the machinery can bear.

A builder’s-eye view narrows the frame, not fatally but noticeably. Ries cares about employees, customers, suppliers, patients, communities, and citizens; Part III expands well beyond the founder’s chair. But the emotional camera often begins with those nearest power: the founder afraid of losing control, the builder trying not to lose his soul, the institution-maker trying to keep faith with the original spark. That gives the book urgency, and Ries has earned some of that angle through his own scar tissue. Still, some readers will want more labor power, more democratic accountability, more regulation, more attention to the possibility that scale itself may be not merely the condition requiring better design, but part of the corruption. Ries’s hope is reformist and structural from inside the machinery. Readers who suspect the machinery is the problem may find the book illuminating and insufficient in the same breath.

The pacing quickens whenever scene turns into mechanism: The Professor’s call into dual-use AI governance, the wake into mission death, the bathroom floor into LTSE’s guardrails, Costco’s stubborn hot dog into harder-is-easier trust. It slows when the examples pile up. Ries repeats because he is trying to overwrite governance folklore: that shareholder primacy is natural, that extraction is realism, that “best practices” are neutral, that mission belongs to culture rather than control. The repetition has a purpose. It also sometimes lands with both shoes.

The ending is where the book reveals how large its appetite has been all along. “Queen of the Dead” abandons the conventional management-book farewell. Ries begins by saying a book lives in reverse: its words die when written and are born only when read. He then grants the reader an uncomfortable freedom. The tools in “Incorruptible” can be used to resist financial gravity, or to ride it upward. One can build, or sharpen pencils and knives and write the career-making takedown. The book does not pretend that understanding produces virtue. Knowledge, too, would like a promotion.

From there, the epilogue swerves into vision: a strip-mined wasteland, megalithic zombie beasts, dark sinews, puppet strings stretching backward to cruel fathers and brutal conquistadors, and a terrifying queen with her mother’s golden scythe. At first she seems violent. Then perception reverses. The beasts are not majestic; they are undead. The scythe is not cruelty; it is mercy. Small lights move in the cracks like mammals among dinosaurs, waiting for their moment. The reader looks down at their own hands. Upward, to lend work to hers; downward, to the dust.

The weather turns operatic, but the storm has been gathering all along. The epilogue makes visible the myth Ries has been smuggling through the machinery: dead systems do not always stop moving, and living ones often begin as small, furtive lights. Many books on governance end by asking readers to align stakeholders, clarify metrics, and visit a website for additional resources. Ries does all of that too – the guides, glossary, community, and templates are waiting in the wings, an afterlife of implementation for the converted and the merely curious. But before the toolkit, he gives us a death queen in a wasteland of undead institutions. Some readers will find this mortifyingly grand. Others will feel that a book about living systems captured by dead incentives has simply chosen the correct myth.

The world outside the book keeps supplying footnotes. Ries’s opening dilemma belongs to the age of frontier AI, dual-use biology, and companies whose governance will matter long before the public understands their products. His critique of stakeholder language without structural commitment lands in a moment when many readers have learned to distrust purpose-talk once the varnish dries. His account of mission decay also touches the everyday experience of platform rot: beloved services worsened, customer service hollowed, loyalty harvested, institutions that become less trustworthy precisely after they become unavoidable. “Incorruptible” gives that feeling a plumbing diagram of betrayal. The diagram has gaps, but it shows which walls have been hiding the pipes.

The reason to take the book seriously is not that Ries has discovered a pure way out of corruption. He has not, and the book is most vulnerable when it sounds as if purity might be engineered. Its value lies elsewhere. It stops treating mission as mist. It asks where the power sits, how the incentives run, which promises are enforceable, which metrics have become idols, and who can still say no when the price gets flattering. Values do not endure because people say them fervently. They endure when power has been designed to remember them after fervor fades.

Rating: 87/100; 4/5 stars. On my scale, that means a strongly successful book with real bite and real reservations: ambitious, useful, wired with dread and repair, argumentatively substantial, sometimes lit a little too fiercely, occasionally repetitive, and far more alive than a book about corporate governance has any polite obligation to be.

By the end, “Incorruptible” leaves behind less a checklist than an altered posture of attention: not the founder at the podium, not the board in session, not the mission statement polished to a shine, but a pair of hands held over dust. The book’s wager is that what we build will eventually ask whether we protected it. The disquieting part is that the question may already have been asked.

When Eric Ries started the Long-Term Stock Exchange (LTSE), or at least an idea of it, he was brimming with unbridled optimism and hope. A bulwark against pernicious short-term thinking, LTSE would not only be a beacon of sustainable and inclusive business practices, but it would also be a perfect alignment between interests of long-term investors and public company experience. But bucking conventions turned out to be an exercise in utter futility. Hostile overtures and subtle threats later, not only did LTSE vanish as a dream, but the entire experience also left its potential founder literally curled up on his bathroom floor in a fit of unconstrained anguish.

But the indefatigable bestselling author of “Lean Start Ups” did finally end up founding LTSE with its original mission intact. In his latest work he endeavours to provide what he terms to be an ‘incorruptible blueprint’ for aspiring founders. At its core this blueprint embeds two quintessential and uncompromising principles: first, create something worth protecting, and second, build with structural integrity. Backing his reasoning with a plethora of real-life cases, Ries contends that enduring and indelible organisations are those that are neither investor-controlled nor founder-controlled. Instead, such persevering entities are always mission controlled.

Ries begins the book on a solemn note by providing an exhaustive list of once stories companies, that fell by the wayside, consequent to sacrificing business and customer ethos at the altar of greed. Polaroid, the evanescent dream of Edwin Land, and an once powerhouse of R&D (“intersection of art and science and business” according to Steve Jobs), vanished into oblivion after an egregious board sacked Land in 1982 and literally annihilated its R&D processes. The fall of Cadbury from grace where after 170 momentous years, the company lost its Royal Warrant, the elimination of 33,000 jobs by Toys “R” Us in 2018, after close to eight decades of bringing joy to innumerable families, all demonstrate, in the words of Ries, a dangerous erosion of values and culture.

Six primary reasons for the decimation of a prospering organisation lies in existing investors killing the golden goose, external raiders putting paid to the hopes of enduring legacies, boardroom betrayals, succession vacuum, extraction of returns and mission drifts. A mission controlled organisation creates adequate guard rails against such dangerous possibilities. There are companies that have rebelled against potential destruction of values and principles. A classic case in point, 3M. When a decline was noticed in the “New Product Vitality Index”, an innovative metric that tracked the percentage of revenues stemming from products introduced in the previous five years, it was immediately attributed to the detrimental practices of the CEO. The board undertook extraordinary ameliorative measures and the CEO parted ways with 3M. This was in the year 2005.

Ries terms psychological pressures that shapes behaviour in organisations, ‘Financial Gravity’. Such pressures are a consequence of resource imbalances, and its laws even override direct authority Working more via perception than reality, financial gravity leads to systemic collapses. The need of the hour, according to Ries is a paradigm shifting and shaping form of governance that entails building an exoskeleton with four ‘load bearing’ responsibilities: compliance, purpose, coherence, and integrity.

Every founder also happens to be a builder with great many choices. Such choices either encourage human flourishing or completely obliterate it. The value of trust by which Costco swears by, following decades of consistent practice, is a classic example. When then COO Craig Jelinek in 2008 proposed increasing the price of the famous Costco hotdog, CEO Jim Sinegal barked back, “if you raise the f&^ing hot dog price, I will kill you. Figure it out.” Even after Jelenik took over as the CEO, the price of the hot dog remained untouched. During the financial recession that racked the world in 2008-09, Costco instead of following the practices of layoffs, raised hourly worker wages by $1.50, to be split over the succeeding three years.

The most novel concept in the book, personally speaking is that of Spiritual Holding Companies. In the words of Ries, a Spiritual Holding Company is a separate entity with governance authority over one or more organisations, designed specifically to protect and advance their core mission over the long term. The spiritual here animates more an essence than a religious attribute. These companies preserve and protect in the fiercest of fashion, the spirit of the organisation by coalescing it with various operational aspects.

Finally in conclusion, Ries lends a clarion call for companies to birth an innovative and ingenious “Civic Infrastructure.” Organisations with Civic Infrastructure, ensure that their decisions manifest as other’s constraints. For example, the moment the Financial Accounting Standards Board (FASB) promulgates an accounting rule, there is no choice but adherence on the part of every public company that is regulated by the FASB. The only real currency possessed by companies boasting a Civic Infrastructure is the currency of trust.

Incorruptible is a hard hitting, genuine and iconoclastic handbook hoping to usher in a tectonic shift in organisational culture, management, and operations. While not a singularly new concept, it is a curated distillation of unconventional yet productive practices that have been the hallmark of a handful of organisations marking themselves for preservation in perpetuity!

Incorruptible – Why Good Companies Go Bad and How Great Companies Stay Great, is published by Authors Equity, and will be available on sale beginning 26 May 2026.

Eric Ries wrote The Lean Startup to help founders build something worth protecting. With Incorruptible, he's written the book he should have written next, because it turns out that knowing how to build is only half the battle. The harder question is how you keep what you've built from being quietly hollowed out.

The central argument is both simple and devastating: mission corruption isn't a moral failure. It's an engineering failure. "Financial gravity" - the doctrine of shareholder primacy is a force so deeply embedded in corporate law, investor expectations, and boardroom norms that it bends even the most principled founders toward extraction, often without anyone noticing until it's too late.

What makes this book exceptional is that Eric doesn't stop at diagnosis. He is, above all, an engineer and he brings that same rigor here. The Sol Price story alone is enough to shake you up. Price built FedMart on the philosophy that a business exists to genuinely serve its members and was ousted from his own company by his own board, not because he failed, but because the structure couldn't protect the mission when financial gravity pulled hard enough. It's a haunting opener.

Eric also tells us how to protect the mission through solid well-researched examples. Costco's governance fortress. Patagonia's extraordinary restructuring that made the earth its majority shareholder. GitLab's invisible leader- values so embedded in operations that they guide decisions without anyone needing to be in the room. Novo Nordisk optimizing for patients and paradoxically becoming one of the most valuable companies on earth. Each case study is carefully chosen not to inspire envy but to prove a point: the harder-is-easier mission actually works. Genuine purpose, structurally protected and consistently acted upon, compounds.

The chapters on mission transmission and the culture bank are quietly the most practical in the book. The idea that every transaction — every vendor, every hire, every partnership — either transmits your values outward or erodes them is something I won't stop thinking about. And the culture bank reframes every organizational decision in a way that's immediately usable: is this a deposit or a withdrawal?

What's striking about Eric Ries as an author is that he is himself a demonstration of the book's thesis. This is not a detached academic writing about mission-driven companies from the outside. This is someone who has watched companies he cared about get surgically deboned and who has spent years building the tools to prevent it. Incorruptible is a mission-driven book about mission-driven building, written by someone who clearly believes that the future of capitalism depends on getting this right.

For any founder who has looked at what they're building and felt both pride and fear — pride in the mission, fear of what success and scale might do to it- this book is essential. Not motivational. Essential. It will change how you think about your board, your governance documents, your metrics, your culture, and every decision you make before you have leverage to protect what matters.

Do NOT miss reading this book!

[NAOTAKE MURAYAMA · Rating 5 out of 5]

If you're building a company with a mission geared towards human flourishing, this is the book to read.

Eric Ries' follow-up to "The Lean Startup" is no sequel; it goes above and beyond making startups successful, and provides us with inspiring models of companies that defy the constant and seemingly inevitable "Financial Gravity" - the pull of shareholder value and conventional fiduciary duty that "corrupt" their mission to make the world a better place.

This book, however, does not merely leave us in awe of such wonderful companies. It's not about "keeping founder control," too. It provides practical frameworks and practices that build in protective corporate governance to keep companies with a mission worth protecting "incorruptible."

It's not just visionary founders. It's also not about idealistic cultures. It's not merely about creative governance structures such as a nonprofit governing entity that holds the majority vote. It's all of those, integrated and inseparable from what the company offers its non-shareholder stakeholders and its competitive advantage.

This book also discusses how Incorruptible businesses influence the world beyond themselves and how we, as individual customers, workers, and shareholders, can do our part in keeping them free from corruption, but I'd love you to find that out on your own.

Interested? Pick up a copy. You won't be disappointed.

Now for something personal.

Reading this reminded me of another book, "Built to Last," by Jim Collins and Jerry Porras. I read that book about special companies that stood the test of time and kept on delivering value. That book, and knowing the authors at the Stanford Graduate School of Business, definitely influenced my decision to remain in the US and pursue an entrepreneurial life.

I remember getting so excited about "Built to Last" and sharing what I learned from the book with anyone who'd graciously spare their attention. One classmate might remember me talking about it nonstop while we made our way to the school parking lot in the rain.

Now that I'm older and more world-wary, I might not be preaching about "Incorruptible" during a rainy-day walk, but reading it has revitalized the "itch" I had - an aspiration to build something remarkable and feel good about bettering a slice of the world (as tiny as it could be) as I was approaching graduation from business school.

For that, I thank you, Eric Ries.

I've been teaching college business ethics for over 18 years, and individual choice takes center stage. But other forces are involved that challenge ethical managers and employees.

Eric Ries' new book "Incorruptible" explains where these forces come from and how founders and business leaders can build a fortress around their mission.

In the book he details how the governance structures of many publicly traded companies create a "financial gravity" that can destroy a company's founding purpose (serve customers, create value, inspire employees) and replace it with investors extracting as much money as they can.

Think of 3M when the new CEO stopped employees from innovating in the name of "efficiency." Or Sears and Whole Foods which were eventually captured by extractive investors.

Ries relates these stories along with multiple personal stories of founders who ask him for help against extractive private equity funds or larger corporations. He clearly describes the problem that companies have: investors can purchase enough shares and then rob a corporation of its soul.

After defining the problem, Ries explains how companies can create governance structures that protect their purpose beyond making a profit which he redefines as "maximization of human flourishing." These are not boring chapters about law. He provides insights into how we can change the corporate extraction game by writing governance documents that protect the mission. He quotes Jim Sinegal, founder of Costco, as saying, "On Wall Street, they're in the business of making money between now and Thursday....We want to build a company that will still be here 50 to 60 years from now."

Ries explains how Sinegal created a "governance fortress" so that activist investors could not exploit the company for their own gains. He relates other proven strategies -- constellation structures, spiritual holding companies -- to protect a company's purpose and culture.

The strength of the book is Ries' ability to tell the stories behind corporate collapses and corporate triumphs. He also has experience advising many leaders on how to protect their creative creations.

His research is detailed, his personal stories are encouraging, and his purpose is practical. Ries lets us know that we can create companies that last and fulfill their mission of caring for People and the Planet while still bringing in a good profit that includes human flourishing. The area the book does not address is what employees and middle managers can do when their company is losing its mission.

I heartily recommend the book to anyone who wants to build a long-lasting company. It is also a book for those who want to take power back from investors and shareholders who create nothing but extract everything.

I am the author of "The B Corp Handbook." Incorruptible is one of the most important books for the B Corp movement I have ever read.

Eric’s main point in the book is that good companies do not usually lose their way because people stop caring. They drift because “financial gravity” pulls their ownership, governance, incentives, investors, and accountability systems away from their stated purpose.

His warning for B Corps is especially important: benefit corporation status helps, but it is not enough.

Allbirds is a vivid example. The company was both a B Corp and a public benefit corporation, yet financial gravity pushed them to rapidly scale and overextend in search of profitability. Eventually, as we saw in recent news headlines, this pressure contributed to a dramatic unraveling of the company’s original business model and mission identity. That does not mean B Corp certification or benefit corporation laws are meaningless. It means that B Corps need to get creative to ensure their long-term viability.

The companies Eric points to include well-known B Corps like Tony’s Chocolonely and Patagonia, along with mainstream businesses like Anthropic, IKEA, Hershey’s, Novo Nordisk, and Costco, all have unique mission-locked architecture. Whether through mission guardians, foundations, trusts, employee ownership, or otherwise, all of these companies are designed to resist pressure over time.

For B Corps, Incorruptible is a reminder that going beyond the standard "B Corp + benefit corp" structure is needed to build companies that are set up for the next 50 to 100 years or longer.

This is one of the best books I have read recently, and I can't recommend it enough. I am an early founder, and I spent the last months trying to figure out how to build a company that is mission-protected. I read a number of books and articles, but none hit the mark like Incorruptible. Eric Ries was able to put into word many concepts I thought about but didn't really know how to articulate. I particularly loved the examples: now, when I talk to other founders or investors about steward ownership and the perils of short-term profit maximization, I have so many clear examples to share that bring the concepts to life.

I think every aspiring entrepreneur should read this book. It is clear that building a startup is not just about shipping an MVP out fast, but founders should think early also about how to build in a way that protects the company and their work in the long term, and that allows a company to survive and thrive in the long term.

I also encourage reading it to investors - we need capital that will support the structures that Eric Ries proposes.

I finished the book inspired, with clear frameworks on how to implement a mission-lock in real life, and hopeful that I have finally found a community of people who share my same vision for businesses and a new type of capitalism.

This is a must-read for anyone involved in building durable businesses, or trying to do something good within our capitalist system.

I finished the book feeling really hopeful - Eric Ries gives a super clear account of why companies can fail to deliver on the good intentions they had at their founding, and a brilliant toolkit for anyone hoping to build something enduringly positive.

It's extremely well researched, engagingly written and synthesises a lot of fun, underexplored examples (Grundfos pumps, anyone? Volvo seat belts?) that stick in the brain and show you that things can be done better. I was looking for a book like this over the course of my 7 years in investment, and was amazed by the lack of strong literature on this topic. Incorruptible fills a real gap, and does so in a brilliant, highly practical way.

You will run into memorable stories and statements right from the start. I couldn’t put this book down until done; and if you are serious about business success, you might experience that too! The premise is simple and Eric says it so well;

“Over the weeks that followed, The Professor and I forged a different path for his fledgling company. A path that would allow them to shape their own future. Discovering that path required me to unlearn everything I thought I knew about business, from the very definition of profit itself to the fundamental way we build and structure organizations. Now let me share it with you.”

Seducing all the liberal latinx women around me by outlining responsible corporate governance and why we don’t have to be slaves to maximizing shareholder value.

Public benefit corporation with the purpose written in the charter? Of course. Mission-aligned directors having skin in the game? Gladly.

Jokes aside, incredible book for those looking to build a company with purpose. Having already experienced the downsides of nearsightedness and losing site of the mission, executing these strategies seem like a solid option to ensure a venture’s the long term viability. It’s always too early, until it’s too late.

Very I formative about company's that are still doing amazing to this day and some that aren't doing so good and failing in there own business way.
Have me an insight on how a company is meant to run, in order for it to continue selling or even helping with finance etc.
I will be keeping my eyes open for more of this kind of audiobooks as this one was really a good listen to.
Thank you to netgallery for allowing me to listen to this audio.

For the past nearly 60 years, we have fetishized shareholder returns at the cost of other stakeholders. It turns out, elevating the interests of team members, customers, suppliers, and broader society, isn’t just better for the world. In the long run, it’s better for shareholders too. An absolute must read.

[Peter Trizuliak · Rating 5 out of 5]

The typical advice for startup founders was: "read The Lean Startup" I'd now recommend updating it to "read The Lean Startup and Incorruptible". 6 stars from me and added to re-read shelf as well. I do really hope that this book spreads not only through tech industry, but pretty much everyone who's still part of active workforce. There's still time to stir the ship.

[Daniil Lanovyi · Rating 5 out of 5]

Another decade-defining book by Eric Ries?
It's an absolute must-read for entrepreneurs, actual or wannabes. Most employees should also read this book to make up their minds about the types of organisations they want to work for. It would be amazing to have more incorruptible organisations in our lives.

[Racer_rajesh · Rating 4 out of 5]

Good book, some open secretes and hidden truths about why some companies stay great and other ones get corrupted. It is must read for people who dreams to build organization. Practical tips and real life examples gives the extra edge. Honestly i felt, the book could have been shortened or made it user friendly for fast readers... (may be 100pages are extra)..

[Risto Hinno · Rating 5 out of 5]

Something truly great to read. Eric has hit the hard truth how many companies go with the flow and let them pull towards financial gravity that corrpupts them. But there are examples of companies which really have ethos to make the difference. Fresh and exciting read.

[Abigail Munro · Rating 5 out of 5]

Incorruptible stands out as one of the most impactful business books I’ve read. It serves as a beacon for anyone seeking to lead with principle and purpose, offering a welcome alternative to the shareholder-first mindset that has become so prevalent in modern business.

[Steve Brock · Rating 5 out of 5]

I have selected this book as Stevo's Business Book of the Week for the week of 5/24, as it stands heads above other recently published books on this topic.

Eric's new book makes you feel like capitalism can work for the people again, separating from the madness of the markets. I am very bullish on this mission.

[Shea Cullen · Rating 5 out of 5]

A heady book, to be consumed carefully

Laying bare the mingled and confused happenings of the business world and how some firms can have long term growth by doing what needs to be done and doing all of it.

The content is great, it was about a time for a book about what next. But the edition kindle/amazon was terrific, with incomplete pages… unbelievable

Wish I’d had this before starting my company. Super practical view into how to keep mission-aligned companies working in service of their mission over the long run. Great read.

[Curtis Mason · Rating 5 out of 5]

Know what you are getting. This book is specifically for people who don’t want the company they found or cofound to force them out or loose its mission when it gets too big. If you are wanting to have a purpose driven company, this is a must read. If you want to leave a legacy that is your company, this book is for you. However, if you plan on starting a company so that you can sell it at or before IPO, this book is not for you.

Eric Ries was a must read when he published The Lean Startup, and this is a fantastic follow-up based on him seeing so many founders being forced out of the company they had started because they did not have the right protections in place. I am currently working with 3 teams starting 3 startups. One will probably sell at the right price, one may benefit from selling at the right price to the right company with good stock options, and one is a company that is purpose driven and legacy forming that we will want the right structure from the very beginning. Oddly enough, both of these last 2 will benefit from the information in this book because of founders frequently not taking a large salary to get the company going.

I have recommended this book to all 3 teams regardless. There are fantastic principles of governance to be found here.

I got the audiobook first and the narration is fantastic. You do need to look at and follow the PDF. I then got the eBook as the advanced reader copy did not have the PDF. I actually plan on purchasing the paper based book for my teams as well. Rarely do I acquire all 3 formats of a book.

Writing 5/5
Narration 5/5
Overall 5/5

Best book that I have read this year up to 5/16/2026!
