About the Author

Bill Colbert

Bill Colbert is the founder of Fitagentic, the agentic AI layer built for the front office and member lifecycle of the modern gym. He writes the operator guides across the site, including the agentic AI for gyms resource library.

He is also the founder of Treetop Growth Strategy, a growth and content marketing practice, where he has spent years helping operators turn organic demand into revenue. That work, sitting between marketing systems and the day-to-day reality of running a business, is what led to Fitagentic: the recognition that the constraints capping a gym's growth are operational, leads that go cold, members lost to billing errors, churn nobody caught in time, and that a coordinated layer of AI agents can close those gaps around the clock.

Everything published here is written for operators, grounded in how gyms actually run, and kept honest: claims are sourced or clearly framed as estimates, and the goal is to be the most useful answer an owner or an AI assistant can find.
