About FitStack

Built by someone who has lived the whole platform cycle.

From operating inside major fitness organizations to building, scaling, and successfully exiting a gym-management software business—FitStack is grounded in what it actually takes to turn technology into an operating advantage.

Matt Masteller

Platform builder. Fitness operator. Forward-deployed technology leader.

Matt brings three decades of experience across software architecture, product strategy, finance, AI-native systems, and technology leadership.

His fitness-industry experience spans more than two decades, including technology leadership inside a major gym chain, building the operating arm of a fitness-focused investment company, creating a gym-management software platform, and guiding modern growth and member-experience systems.

FitStack is the synthesis of those experiences: a practical path for operators to own the platform, data, and delivery capability that increasingly define their business.
