SaaS development is unforgiving — get the foundations wrong and you spend year two rewriting them instead of getting customers. We've spent 10+ years shipping production web applications and the stack is the same every time: React + TypeScript on the front, Supabase (Postgres + Auth + Storage + Edge Functions) on the back, Stripe for subscriptions, deployed globally on the edge.
That stack gets you to a working, billable MVP in weeks — not the 6 months a traditional agency quotes. Multi-tenant rows-level security, Stripe customer portal, magic-link auth, role-based access, audit logs: all wired in from the first sprint, not bolted on after launch.
Have a look at our web apps service or the Tim's Weather case study — built on the same stack we use for every SaaS.
