Built for operators.
Priced like infrastructure.
Cinch is the member-management platform we wished existed when we started building software for fitness, wellness, and athletic operators back in 2018. Mindbody charges $279/mo for an app members complain about. ForeUP charges $1,500/mo for a tee sheet that hasn’t shipped a real feature since 2014. We can do better.
We didn’t set out to build SaaS.
We were just helping a friend.
Mindbody. ForeUP. Rock Gym Pro. Jackrabbit. ClubAutomation. CourtReserve. They all charge enterprise-software prices for the privilege of running a small-to-mid business. Members hate the consumer apps. Operators hate the admin tools. Nobody is building anything new in the space because the incumbents have brand inertia.
Treehouse is a full-service athletic club in Draper, Utah — pool, rock wall, pickleball courts, spa, Kids' Club, 40+ weekly classes. They wanted family memberships (Mindbody can't model them), an AI concierge (nobody had shipped one), and a native-feeling member app (industry-wide gap). We built it. They've been running on Cinch ever since.
Multi-tenant from day one. Every customer gets their own subdomain, their own brand, their own Stripe account. Members never see the word Cinch — they see YOUR club. We make money via a tiny application fee on Stripe Connect transactions (0.5%) or a $199/mo flat for operators who want predictable billing. No upsell modules, no fine-print fees.
Three operating principles.
We're on Vercel + Neon + Stripe + Vercel AI Gateway. Operationally that's a fraction of what Mindbody pays to run their legacy infrastructure. We pass the savings on instead of pocketing the margin.
Every feature you see on Cinch was built because a real operator needed it. Treehouse asked for family memberships. Bear Creek asked for dynamic tee-time pricing. We build for the specific need, then generalize.
Cinch is a platform, not a SaaS dead-end. Use our REST + tRPC API to build your own custom marketing site, member app, or admin tooling. Or pay us to build it for you. Either way: you own the relationship with your members.
GullStack builds Cinch.
GullStack is a small agency in Salt Lake City. We’ve been building member-management platforms for fitness, wellness, and community organizations since 2018. Cinch started as a custom-build for Treehouse Athletic Club — we kept generalizing it until we realized other operators wanted the same thing.
We’re a small team intentionally. No SDRs, no enterprise sales org, no investor pressure to upsell modules. The same people who build the product talk to the customers.
