Don't Spend Six Months Building Something Nobody Wants

We build a working prototype of your product idea, test it with real users, and hand you the data. All in 14 days, fixed price.

What You Get in 14 Days

Working Software, Not Wireframes

A functional prototype with real logic that your target users can test end-to-end. Not slides. Not clickable mockups. Software that actually runs.

Real Traffic, Real Signals

We set up analytics and help you run a small ad campaign to drive your target audience to the prototype. You'll see who signs up, where they drop off, and what gets traction.

A Clear Go/No-Go Decision

Signup rates, engagement patterns, drop-off points. Concrete data to back your next move, whether that's invest, pivot, or walk away.

Code You Keep Building On

The prototype runs on a production-grade stack. If the data says go, development continues on the same codebase. No rewrite, no wasted work.

Fixed Price, No Surprises

You'll know the exact cost before we start. If the sprint runs over, we absorb it. No hourly billing, no scope creep, and no surprise budget conversations halfway through.

Done in Two Weeks

From kickoff to validated prototype in 14 days. While your competitors are still scheduling planning meetings, you have market data.
