The Rise and Fall of Explorys and IBM Watson Health
In 2015, Explorys was a healthcare intelligence cloud company that had built one of the largest clinical data sets in the world, representing more than 50 million lives. It provided secure cloud-based solutions for clinical integration, at-risk population management, cost-of-care measurement, and pay-for- performance. The acquisition of Explorys complemented and strengthened the IBM Watson Health Cloud platform and empowered IBM’s vast ecosystem of clients, partners, and medical researchers to surface new connections among diverse and previously siloed healthcare data sets. The combination of both Explorys and IBM Watson Health was expected to spur the creation of a new generation of data-driven applications and solutions designed to advance health and wellness. So, what went wrong?
IBM Watson Health is a massive case study in healthcare innovation gone awry. IBM was one of the oldest and largest technology companies in the world and was riding a tailwind with IBM Watson’s Artificial Intelligence success on Jeopardy in 2011. The Watson Health division was seeded with multiple healthcare acquisitions, one of them being Explorys. Explorys had a portfolio of hosted population analytic solutions and the largest clinical dataset in the United States at the time, at approximately 50 million de-duplicated patients. The newly created division was loaded with potential and seemed destined for success. Yet Watson Health went from being founded in April 2015 to imploding in May 2018 in a little over three years and took Explorys down with it.
IBM Watson Health’s ascent and descent were covered by both healthcare and mainstream media. Watson Health was self-described as IBM’s "Moonshot" in healthcare. This venture failed, and it cost IBM billions of dollars. These were expensive lessons on managing innovation in healthcare, but also on managing innovation in general. This book chronicles the story of Explorys and IBM Watson Health and what led to its downfall in just three short years. Written by one of Explorys’ founding engineers, the book relates the rise and fall of both Explorys and IBM Watson and provides a message for future tech entrepreneurs and IT managers alike.

I don't often read business books and feel like someone finally said the thing I watched happen in real time. This one did that.
Doug Meil tells the story of Explorys, a health data startup born out of Cleveland Clinic that built something genuinely remarkable and what happened when IBM acquired it as part of the Watson Health moonshot. It's a story about innovation, acquisition, organizational failure, and the ethics of doing business in a field as consequential as healthcare.
What I appreciate most is the honesty. Doug doesn't write like someone settling scores or polishing his legacy. He writes like someone who genuinely wants people to learn from what happened. The early chapters about building Explorys - the team, the mission, the technology have real warmth. The later chapters about navigating IBM's bureaucracy have real pain. Both feel earned.
The thread that runs through everything is character. Meil is a technologist who cares deeply about solving real problems, building good teams, and doing business with integrity. The book quietly illustrates what it looks like when someone holds onto those values inside a system that isn't designed to reward them and what it costs.
The reflection on ethics is one of the book's strongest contributions. There's a reason the companies that cut corners overpromising capabilities, ignoring what the data actually represents, optimizing for the deal rather than the outcome keep ending up the same way. Doug doesn't moralize. He just shows it.
My one wish: a deeper exploration of why Explorys pursued outside investment when it was doing well. For anyone interested in the startup-to-acquisition arc, that chapter of the story holds lessons that deserve more space.
For readers interested in healthcare technology, AI, leadership, or anyone who has lived through an acquisition and wondered whether anyone else saw what they saw — this book will resonate deeply.

A Clear-Eyed Case Study of Ambition, Culture, and Reality in Healthcare AI
Doug Meil’s The Rise and Fall of Explorys and IBM Watson Health is a rare and valuable read: a grounded, insider-level account of how one of healthcare’s most ambitious data and AI moonshots ultimately misfired. Rather than leaning on hindsight bias or simplistic blame, Meil carefully unpacks the strategic, cultural, and operational forces that shaped both the promise and the downfall of Explorys and IBM Watson Health.
What makes this book stand out is its balance. It neither romanticizes innovation nor dismisses it. Instead, it shows how real-world healthcare constraints—data quality, workflow integration, incentives, governance, and culture—collide with Silicon Valley–style ambition. The result is an honest examination of why scaling healthcare analytics is profoundly harder than it looks on paper.
This is not a technical manual, but it is deeply informative. Business leaders, healthcare executives, product managers, and investors will find practical lessons around M&A integration, organizational misalignment, and the dangers of overpromising transformative AI without sufficient operational grounding. The book also serves as a cautionary tale for anyone assuming that capital, branding, and talent alone can overcome structural complexity in healthcare.
If you’re interested in healthcare innovation, enterprise AI, or learning how bold visions succeed—or fail—inside large organizations, this book is well worth your time. It’s thoughtful, sobering, and ultimately constructive.
Highly recommended for healthcare and technology leaders who value lessons learned over hype

What a wonderful memoir of a truly amazing company and team. Explorys was the single largest collection of sheer talent I have ever seen in Cleveland, and this book is a wonderful chronicle of how that talent built a solution ahead of its time, and then unfortunately how that talent and opportunity was destroyed by mismanagement. I have to admit, there was a tinge of sadness at the end of the book, realizing the potential Explorys had and was squandered by people who had no business being in charge of it post-acquisition. If Explorys had been built with today's cloud and AI technology, and had maintained independence, I have no doubt it would have become the center of Cleveland's health tech industry. That said, everyone involved with the company should be very proud of what you built, especially Doug, as chief architect.

The history of Explorys and the acquisition by IBM is one of the most interesting case studies, not only in healthcare tech, but startup tech.
Doug Meil does an excellent job recounting what it took to build what no one else had in the market when value based care and population health were emerging concepts.
Behind the prestige of IBM, lies dead innovation. The book calls it out well by highlighting the “blue washing.” The red tape of a company with 400,000 employees is never going to make a footprint in real world problems. IBM will acquire your company and cease innovation, taking you out of the competition.

An insightful and candid look into a promising healthcare startup: from its founding, successes, and eventual downfall. Doug provides an insider's perspective, warts and all, of the kind that's often buried beneath corporate politics and company narratives. His writing is detail-oriented but succinct, based on his real-world experiences at Explorys and enriched by a history of writing tech posts and articles. It will be obvious to any reader that Doug is both an expert in his field and perceptive of the bigger picture beyond his engineering expertise.
But this book is not about the author: it is about Explorys and IBM, and it does an excellent job not just chronicling its rise and fall, but explaining why: what worked, what didn't, what decisions mattered, from the choice of technologies to an understanding of the client space and acquisition headaches, all wrapped up in an engaging and entertaining story that I genuinely enjoyed reading. The anecdotes and tangents about a scrappy software company building itself out with a ragtag team are sure to resonate with engineers in the field. To anyone wanting to learn more about the IBM Watson Health Explorys story, gain invaluable insight into how a healthcare startup can function, grow and degrade over time, for anyone wanting a case study for what to do and not do for a small and quickly growing business, for anyone wanting a broader understanding of the healthcare data world and how it functions, for engineers, business professionals, and entreprenuers, I cannot recommend it enough.

I don't usually find myself staying up late for a book about a corporate acquisition, but here we are. Doug's retrospective on Explorys and what IBM did with it is frustrating and fascinating in equal measure — and he tells it with the kind of honesty you only get from someone who really understood what was lost. Technical but still accessible for a non-tech audience, and especially important in the age of AI-everything. A great read, and long overdue recognition for Cleveland's health tech scene.

Essential for executives & engineers: the billion dollar-sized pitfalls to solving healthcare.
Executives targeting healthcare: this is a postmortem you cannot pass by. Any venture that underestimates the wicked problems of healthcare tech will prove lacking in strategic vision or execution. Likely both—and AI will not save you.
This is a Distinguished Engineer explaining the icebergs leadership missed. Meil shows in detail how IBM’s M&A approach went awry in just a few months and destroyed billions invested in 3 years. He tours the canyon between leadership’s half-dozen ideas of what to do, and what was actually feasible and worth pursuit.
Software engineers: you will find lessons for every rung of your career. If you’ve worked a few years—at a multinational corporation, a startup, or anywhere in between—you will also find some catharsis. Build your own desk, move offices, prepare for acquisition, fight over intellectual property, dodge the water caving in the ceiling, worry about another lost customer, handle managers who believe anyone in sight is their workhorse. This runs the gamut.
Meil shows a passion for software engineering and a yearning that it be marshalled to solve healthcare's problems. He tells Watson Health's story with wryness, even bitterness at times. But he shows the human spirit in the face of it all, through humor. Have you had a boss swoop through like the “Eye of Sauron,” or seen a project allocations pie chart so overloaded, it seemed like Mac’s "pinwheel of death"?
I highly recommend giving this a read. It is a truly unique perspective, and may be the best on this topic since Hacking Healthcare.

This is an excellent memoir retracing the steps of how a leading edge technology startup was acquired by an established business, massively mismanaged and finally killed off. With several deep dives into the technology needed to make large scale health data usable, this is a journey that will be appreciated by anyone who is interested in what a tech startup looks like, the challenges they face along the way to acquisition and the heartbreak of watching a great idea be killed by managerial incompetence, impatience and greed. I would recommend this to anyone who has gone through a similar experience or anyone with a general interest in how the technology sector sausage is made.
It's a quick read, a real page turner and I enjoyed every page.

This book is a nostalgic memoir for anyone who worked at Explorys, and it's certainly interesting enough to captivate the right audience. You don't have to be an engineer, you don't have to be from Cleveland, but if you're one or both of those things you'll find this book particularly intriguing.
It's a personal memoir, a tale of corporate infighting and dysfunction, a business management cautionary tale and case study, a technical overview, and an insight into the Cleveland tech scene, all in one concise package. When I pre-ordered the book I didn't expect the book to even include pictures, and that was an unexpected positive highlight.
For many who worked at Explorys, it probably answers a lot of questions about "what the heck was going on?"
There is an approachable and interesting technical discussion of the Exploys platform as well as its context within certain time period in the technology industry. I think anyone working for a startup or considering working for a startup will find a helpful takeaway or two from Doug's account of his experience.
I see a lot of parallels in today's AI rush to this time period's obsession with big data and, more egregiously, blockchain technology. The personal account of the slimy executive egos involved with this specific startup resonate with examples of executive ego we see all over today's tech industry nationally. For example, the idea that Blockchain technology could solve poverty in Cleveland seems comically silly when said out loud today, but real people with real egos were trying to sell that idea with a straight face to non-technical people who didn't know any better. That particular cautionary tale seems like it is going to be a strong analogy to a lot of today's tech executives who are making moonshot claims about AI Large Language Models (LLMs) and their oversold abilities.
A truly useful critical review will point out drawbacks and negatives, and there are a few. Some sections felt a little bit skippable, and some of the illustrated figures and technical drawings had some readability problems in the final print. Maybe the biggest drawback is that there isn't a satisfying ending, but that's really not the author's fault - that's just how the Explorys story ends. Real life isn't always happy endings, is it?

“The Rise and Fall of Explorys and IBM Watson Health” by Doug Meil is a terrific read for those that appreciate the counter-intuitive outcomes driven by corporate ineptitude.
A brilliant start-up squeezed into oblivion by the gravity of Bureaucratic Think and Corporate Inflexibility. Doug’s tale regarding the Explorys experience does well highlighting the pitfalls when large corporations seek to forcefully conform that which they do not understand or appreciate. For those in the world of M&A, Doug outlines many lessons that should be avoidable. For small firms seeking a glorious exit through acquisition, this book should temper your enthusiasm and hopefully help you vet your next phase and potential suitors.

A market, a technology, some smart people.
In start-up world savvy founders can make a ton of money with only one of those three things. The magic of Explorys was that we had all three. Doug was the guy responsible for the technology; he’s also that rare founder who is a delight of a human being. He remembers that my kid was obsessed with light sabers, he is kind, brilliant, and inclusive. Read his book and you’ll learn about business, technology, and start-ups. But you’ll also feel something - what it was like to be there, exciting, claustrophobic, exhausting, blue-washed, sad, disappointing - we really thought we were going to make healthcare better for everyone, we didn’t. What we did was make friends for life.

Doug is not only a great technologist, but he is a great writer. This is an engaging ride through a deeply technical company touching on culture pains, tech growing pains, and the hubris inherent in many acquisitions by the acquirers. It touches on the human aspects of building a company and sadly, seeing it get pulled apart under the "best intentions". what they can't take away is the joy of building something great, which doug and others at Explorys did.

Part business case study, part personal memoir, part engineering satire. All a great read - highly recommend!

I worked with Doug during this period in IBM history, and I can attest to the accuracy of his account. Although Doug’s takes are measured and thoughtful, reading as an ex-IBM employee felt like a vindication of the chaos the rest of us in Watson Health felt back then.
Doug is a great writer and tells his story without bitterness, which would have been understandable given his experiences. Doug’s character comes through so clearly in his writing. The warmth and appreciation he shows for the early days of Explorys and the team’s hard work building something come across just as genuine as he is in actual life off the page. Doug gave a damn, so when his tone shifts as the signs of political undercutting and corporate “leadership” rot start seeping in, you can feel the grief. Reading this I felt like I understood his mourning for something that could have been great but was squandered instead.
I may be biased (having been there for some of it myself) but I think any startup team considering selling to IBM (or really any huge international tech brand) should read this before signing anything. Learn a bit about what you might be getting yourself into, the challenges you’ll face. IBM may have changed leadership since the Watson Health days, but some of the same non-strategic reactive management and vaporware sales incentive structures are still there, ready to blue wash over and ruin a team’s product vision.
The book is honest in a way that corporate post-mortems rarely are, by telling a story of people wanting and trying to do good work despite all the interferences put upon them by a place like IBM. It’s a great cautionary case study, and you don’t have to have even worked at IBM to get something out of it.

I’m currently reading this book in dead tree edition (not kindle).
I worked there, from Dec 2016 - Feb 2021, which covers both the time just before the acquisition, to the tenth round of layoffs in my area. (The layoff count is different depending on where you were sitting.)
So I have a perspective informed by being in several startups, and being in several startups that didn’t Start-up, working in AI both recently and still - and having lived through a good portion of the time period in the company that the book covers.
From a general technical professional perspective with a context in startups and AI, the book is interesting, useful for perspective, and it meshes the business, relationships, and technical aspects of the primary architect contributor and technical lead role.
It is engaging, wistful, nostalgic, and at times funny. Given that the end is well known in the title and the news - it is also a cautionary tale of what can happen even when things all appear to be aligned - and then they aren’t.
From an insider’s perspective - it also gave me insights into what the other business division siloes of the Explorys-based division did. When you are head down working on your piece of the puzzle you don’t always get to see outside of that area. I worked pretty hard to have more awareness of those areas - and the other business divisions. But this still adds to the whole vision of the puzzle.
Still reading -and might have more to say at the end.

Doug Miel writes a fascinating, suspenseful and well written story about the merging of a small entrepreneurial medical software company and an institutional corporate giant’s AI system that famously developed natural language question answering. In bringing two diverse corporate cultures and technologies together to feed a single mission, Doug and his team are in the center of attempting to streamline IBM Watson Health with the Explorys medical diagnosis and informational platform together to strengthen and transform the physician – patient experience at the Cleveland Clinic. Incredibly ambitious over several years of effort by these software teams, the challenges to unravel and peel back external complexities to make the mission a reality become too overwhelming. As a software engineer, Doug’s account reads with the suspense of a thriller and is a story of ambition, resilience, and the unpredictable realities of merging two worlds that in the end weren’t likely designed to fit together. Once you start reading, it’s hard to put down.

The Rise and Fall of Explorys and IBM Watson Health offers a thoughtful insider perspective on one of the most ambitious attempts to apply artificial intelligence to healthcare. Written by a founding engineer of Explorys, the book provides a clear and engaging account of how enormous promise, bold investment, and cutting-edge data initiatives collided with the realities of healthcare systems, organizational culture, and technical limitations.
What makes the book particularly compelling is its balanced approach. Rather than simply celebrating innovation or assigning blame, it carefully explores how factors such as data quality, workflow integration, incentives, and leadership decisions shaped both the rapid rise and eventual collapse of Watson Health.
Overall, it’s an insightful case study for anyone interested in AI, healthcare technology, or the challenges of bringing ambitious technological “moonshots” into complex real-world environments.

Overall, it’s an insightful case study for anyone interested in AI, healthcare technology, or the challenges of bringing ambitious technological “moonshots” into complex real-world environments.

You'll laugh, you'll cry, you'll learn stuff, then laugh again- a cautionary tale, expertly told
This book is a well-written memoir centered around the unfortunate fall of a once promising and exciting startup in the healthcare tech space. It’s an engaging and easy to read tale in which the author provides great insight into the events that led to the end of Explorys and IBM Watson Health. The author did an excellent job telling his story while maintaining professionalism and also providing entertainment throughout! Quite a few lines in there definitely made me laugh out loud!
Highly recommend!

As an Explorys employee, I was completely engaged in reading Doug's memoir. I finished it in less than 2 hours.
The details were perfect - just enough to dig your teeth into, but not so "in the weeds" that it would overwhelm you. His descriptions of the technology were great, but the best part was how accurate his take is on how IBM took what "worked" and essentially chloroformed it.
If you're the least bit interested in healthcare analytics, local Cleveland business, or how business can grasp defeat from the jaws of victory, pick up this book!

I worked with Doug during my time at IBM Watson Health. While our paths didn’t cross often, many of the situations and observations he describes mirror my own experience there.
I would not trade that time for anything. The opportunity to work with smart, driven people like Doug and many others was a real perk, and there were moments when it felt like we were part of something meaningful and ambitious.
At the same time, Doug captures the very real challenges of trying to get things done inside a company of that size. The complexity, the layers, and the friction that come with scale were ever present, and his stories reflect that reality with honesty and clarity.
For anyone who has worked inside a large organization, especially one trying to innovate quickly, this book will feel familiar.

A great read. It visits the company's chaotic starting years, Thunderdome-esque acquisition, and whimper of an end.
Both the technical and business sides of the company are covered in a digestible format.

A captivating narrative about innovation derailed by acquisition and how so much potential was squandered by corporate politics. A cautionary tale.
Anyone who has scaled a business or gone through a merger or acquisition that reads this will feel seen.
Mr. Meil does a great job of explaining complex technical concepts in a way a non-software engineer can understand and navigates the difficult path of compelling storytelling while sharing enough detail.

(Disclosure: I was part of one of the other Watson Health business units and so my views may be very different to those of a outsider)
Some interesting insights, the history of Explorys and its journey to acquisition is well presented. The internal struggles of Watson Health are presented as the author experienced them. But for me that is the real weakness here, the story of the fall of Watson Health, I feel, is so much bigger than the authors experience and so that part of the story feels like only a fragment.
Beyond that, there's some small parts where I was in the same rooms as the author, and left with different memories - different fragments in different heads, perhaps.
