Every project uses the same simple model: pick the delivery package, and the exact price is calculated from the complexity of your scope. You see the locked number before you commit.
Working AI-generated software
No senior-developer review is included on this package. Best for founders who need a demo yesterday and will iterate themselves.
AI speed with human polish
The most popular package. Suitable for pre-seed demos and controlled user testing.
Production-ready data foundations
Best when you expect a full engineering team to inherit the codebase within the next quarter.
Battle-test with a real audience
For founders planning a controlled real-world validation window immediately after handover.
Paid via Stripe once you approve the proposal. Work begins the next business day.
Paid on final delivery. IP transfers at this point. There is a fourteen-day final-review window built in.
Larger scopes occasionally split into three installments. Discuss during the scoping conversation if you need this.
Each package multiplies a per-project baseline that we calculate from the complexity of your scope. Because complexity varies enormously — a simple internal tool is not a two-sided marketplace — we don't publish generic price tags. Describe your idea in the builder and you'll get the exact number, locked, in minutes.
We score the number of core entities, integrations, user roles, non-trivial flows and industry-specific requirements. That score maps to a baseline price. Your package choice then applies a multiplier on top. The whole calculation happens automatically the moment you submit your idea.
Package prices are already positioned to reflect the value delivered — for example, the one-week package is priced substantially below the three-week baseline because it includes no human review. Beyond that we don't run seasonal discounts.
You can, up to the point where work starts. Once we're building, changes go through the change-request flow. The whole point of picking a package at the start is that both sides know what's being delivered.
No. We're a delivery service, not a retainer shop. Once your MVP is delivered you can either extend the codebase yourself, hand it to a dev team, or come back for a follow-up delivery under a new fixed-price scope.
