The founder had a clear idea, a list of interested studio owners and no software: booking, memberships and payments for small fitness studios. I turned it into a working product: a landing page, sign up, subscription billing, a booking calendar members use on their phones, an owner's dashboard, and an AI assistant that drafts class descriptions and member emails in the studio's own voice. I launched it in stages, starting with the 5 studios already waiting, and fixed what they found every week. Result: live in 10 weeks, and 40 paying studios in the first 3 months.
