Twin Oaks

What Twin Oaks does

Twin Oaks (legally TOSD Corporation, also doing business as Twin Oaks Software, Finagy, and Requr) is a privately held, U.S.-based vertical SaaS provider of gym and health-club management software. Founded in 1991 in Berlin, Connecticut, the company has continuously served the fitness industry for over 30 years, primarily targeting mid-market fitness clubs, health clubs, and recreation centers. The platform provides an integrated suite covering member management, flexible billing (monthly, bi-weekly, quad-weekly, annual, custom cycles), EFT and credit-card payment processing, returns management, scheduling, access control, CRM, and marketing automation, with deployment options spanning cloud, desktop, and hybrid configurations.

The product architecture centers on a core club management system extended by modular offerings: the Member Advantage branded mobile app (iOS/Android), Club Marketing automation, Returns Management, custom Keytags & Gift Cards, and Client Relations support services. Twin Oaks differentiates technically through its status as a registered ISO of PNC Bank, N.A., which embeds payment processing directly into the platform under interchange pricing and supports in-house failed-payment recovery; a PCI DSS-compliant infrastructure; and an 18+ partner integration ecosystem including HubSpot, Zapier, Netpulse, Perkville, HydroMassage, and others. Data conversion and migration are handled in-house, supporting customer switches from competing platforms.

Twin Oaks monetizes primarily through flat monthly subscription fees scaled to billing activity (with no percentage-of-dues model and no annual contract requirement), supplemented by interchange-based payment processing revenue from its ISO business and ancillary merchandise sales (keytags and gift cards). Go-to-market is sales-led and direct, anchored on the healthclubsoftware.com website with demo and free cost-efficiency assessment CTAs, supported by a U.S.-based client relations team and Carole Oat as National Sales Manager. The company reports thousands of gym clients and 90%+ annual retention, with multiple customers on tenures of 10-20+ years.
