API volatility
State and data handling built for a demo, not a live API with real volumes.
No test coverage
Every change your team makes is a gamble made blind.
Accessibility gap
A market you're excluding and, increasingly, a procurement blocker.
Auth debt
Handled naively because the prototype never had to be safe.
No API contract
Someone still has to decide what the actual contract with your backend is.
Your team inherits the prototype. The technical debt is the brief now.
Fair questions
"How is this better than the AI dashboards everyone's rolling out?"
We wire it to your actual API, write the tests your team will rely on, and hand over a codebase with a 30-day warranty — not more AI output for your team to debug.
"Do we have to throw away what the founder built?"
The prototype is the spec, not the code. The Foundation and SaaS Starter are built fresh around your actual brand and API, so the vision survives even though the code doesn't.
"We don't have an OpenAPI spec yet."
Not required to start. We'll build the initial feature set against a reasonable API shape. Provide a spec later and there's a small reconciliation cost, same as any SaaS Starter engagement.
What people say
15+ years building production frontends, most recently AI-assisted. Rivetous runs its own marketing site and showcase on the same Foundation it sells.
"Whatever he commits to, he consistently delivers on. He has harnessed agentic coding tools well ahead of most of the industry and pairs that with genuine product instinct."
Product Owner and Engineer
"Deep React and TypeScript experience. Give him a problem and he will find a sensible way forward without overcomplicating things. A calm, dependable approach that teams quickly come to rely on."
Senior JavaScript Engineer
"An uber-talented developer with a knack for always finding the best solution. Book him, he will not just do it, he will do it mighty well."

Find Out What It Will Take
Send us the prototype and we'll come back with a short written note — what's solid, what needs to change before real users touch it, and how a SaaS Starter sprint would scope around your real API. Back to you in one to two working days.
