One to four weeks from written idea to working software. Fixed scope, fixed price, senior-developer review on every package from week two onwards. Built for founders who need a real product in front of real users — not another Figma prototype.
Traditional MVP development is slow because a single person has to do everything — scaffold the app, write CRUD endpoints, wire up auth, style the UI. That is the mechanical part, and it is exactly what modern AI code generation is good at. What AI is not good at yet is judgement: choosing the right data model for how a real business will evolve, spotting a subtle race condition, or knowing when a shortcut will bite in production.
We split the two. AI generates a running app from your scope description in hours, not weeks. Then, on every package from the two-week option onwards, a senior developer reviews the output, applies a targeted bug-fixing pass, and works with you on iterations. The result is software that launches at agency-quality standard on an AI-native timeline.
Calendar time, not billable hours. Pick the package that matches your runway.
Included from the two-week package onwards. Real code review by a human.
From week three onwards: a documented data model. Week four: full feature docs.
If you already have a technical co-founder and eighteen months of runway, you probably don't need us. If you have four weeks and a market question that needs a real answer, keep reading — or start a scope now.
Between one and four weeks of calendar time, depending on the package. One-week builds ship a working AI-generated app with two hours of iterations. Four-week builds ship the same core software plus senior-developer review, a documented data model, twelve hours of iterations and full per-feature documentation.
It's more than a clickable prototype. Every package ships as running software with real backend, real database, and real user flows. What varies between packages is how much human review, documentation and consulting time is included on top of the AI-generated base.
From the two-week package onwards, a senior developer reviews the AI-generated code, applies a bug-fixing pass, and pairs on iterations. On the one-week package there is no senior-developer review — the trade-off is speed and cost.
You get the full source code, deployment scripts, and — from the three-week package — a documented data model. You own 100% of the IP once the final invoice is paid. Ongoing changes are quoted separately, or you can hand the codebase to any dev team.
A freelance MVP typically takes two to three months and depends on one person's availability. An agency takes longer and costs multiples of our packages. We compress the timeline by having AI do the mechanical scaffolding and senior developers spend their hours on the judgement work — architecture, review, and iteration.
