Shortly after Fine and his collaborators developed the GROW Model, the partners went their separate ways, each utilizing his own approach to the model. Since then, Fine has steadily refined and built upon the original model. A host of significant innovations to the GROW Model occurred at InsideOut Development, which Fine founded in 1985 in the UK and eventually relocated to Utah in the United States.

InsideOut Development is a professional services firm that provides leadership, management, and front-line employee training programs; executive coaching services; team performance workshops; and reinforcement services to a large global clientele. The company, recognized as a leader in developing manager-as-coach skills, trains tens of thousands of people annually using the GROW Model and other innovative tools and programs developed by Alan Fine and the InsideOut Development team. The company also provides instructional certification and has certified thousands of facilitators in its program offerings. During the past two decades, Fine and his collaborators at InsideOut Development have created targeted products and services that use the GROW Model tailored to a wide array of clients, applications, and contexts.

Fine's approach has led him to become a prominent performance trainer and coach for leaders in diverse fields of endeavor–from corporate executives and entrepreneurs to educators and professional athletes. In the organizational arena, InsideOut Development has worked with some of the world's most respected organizations, including BP, Cadbury Schweppes, IBM, Proctor & Gamble, NASA, and the U.S. Navy. Fine has received considerable attention in the U.S. and throughout the world for the often-dramatic performance improvements of prominent athletes, including former Davis Cup tennis star Buster Mottram and Professional Golfers' Association (PGA) golfers Stephen Ames, Bradley Dredge, Paul Lawrie, David Llewellyn, Colin Montgomery, and Philip Price.

Ames has publicly credited Fine for accelerating his emergence from relative obscurity to win the 2006 Players Championship by an astounding six strokes. "When I started working with … Alan … in 2004, there was a noticeable difference in my game," Ames said in a 2009 Golf Digest interview. "After that, every year has been a great year." According to Ames, Fine's guidance helped him remove internal performance interference and "play more naturally, like Stephen Ames the instinctive player rather than Stephen Ames the technical player."

The GROW Model is virtually universal in its application. The model's efficacy transcends boundaries of culture, discipline, and personality. "I've seen this help people in large corporations and small companies; from high-tech to finance; and in government, education, and athletic settings on multiple continents," Fine says. "It just works."
