What you get
You get a platform built for daily use by paying customers, not for a demo.
That covers several user roles, billing, integrations, reporting and the operations around them. Our default stack is Next.js, TypeScript and Postgres, hosted on Vercel or your own cloud. We adapt when your team already runs something else.
How the work runs
We ship in weekly increments, so the platform is usable long before it is finished.
A fixed-price discovery phase comes first. Then we work as a monthly team sized to the roadmap and reviewed every quarter. Mixed teams are common: we set up the codebase, CI and review process so your developers and ours ship into the same repository. New requests go on a shared list, we estimate them, and you decide what moves.
What it does not cover
A first platform release is not a two-week job.
If you need to prove one idea before committing three to six months, start with the two-week MVP. Marketing websites are a separate service, Websites & Landing Pages.
