ABC Fitness
“Can a fitness-industry billing utility become the full financial operating system for gym and studio operators globally — owning payments, lending, insurance, and member management in one vertical SaaS platform?”
Founded in 1981 as American Billing Company, ABC began as a pure billing and payment-processing utility for gyms, automating EFT and credit-card drafting for health club membership dues. Over time it evolved into a full club-management SaaS platform (rebranded ABC Fitness Solutions), adding revenue-cycle management, member experience tools, and analytics. Under Thoma Bravo ownership it moved upmarket and accelerated an M&A strategy, acquiring Glofox in 2022 to extend into boutique fitness studios globally. The company has since layered embedded finance directly onto its platform — launching RevenueNow (working-capital lending for gym operators) and ABC Fitness Insurance — transforming from a payments utility into a vertical fintech OS for the fitness industry.
