What it is.

The cheapest way to find out whether an idea works is to make it real enough to react to, without building it. A prototype turns an assumption into something a user can click through, get stuck in, and tell you the truth about.

It's the fastest, lowest-risk corner of the build. One to two weeks of focused design buys you evidence that would otherwise cost a quarter and a chunk of runway to learn the hard way.

Who it's for.

  • Founders pre-build who want to validate the flow before committing to it.
  • Teams heading into a raise who need something tangible to demo.
  • SMEs weighing a six-figure build who want proof before they sign it off.

What you get.

  • A clickable, interactive prototype of your core flow (Figma).
  • The key screens and states, designed to feel real.
  • A short test script for putting it in front of users.
  • A readout of what to keep, cut, or change before you build.

How it works.

It starts with a free discovery call. We confirm the fit, agree the scope and the fixed price, and book the dates. No drawn-out scoping forms, no surprise invoices. You know exactly what you're buying before you commit. You walk away knowing whether the idea holds, before you've spent the money proving it doesn't.
