Starter · Before you build

Prototype: a working first piece of your app in three weeks

You know it’s good, and you can’t make anyone else see it.

We build the first real piece, in code you own, so the people who need to believe can hold it in their hands. About three weeks.

What’s true now

You know it’s good. You’ve known for years. And a deck can’t make anyone feel it.

What’s true after

The people you needed to convince stop asking you to explain it, because they have held it in their hands.

The first small piece of the thing, set right, so the people who need to believe can.

Your timeline, start to finish

  1. 01We pick the one slice that proves it.
  2. 02We build it as the first increment of production, in code you own from day one.
  3. 03We hand it over working.
What you walk away with

A working prototype you own outright.

The source is the start of your real app. You never pay twice for it.

  • You stop explaining the idea and start handing it to people.
  • The code is the beginning of the real thing, so nothing is paid for twice.
  • You own the repo from the first commit, whoever builds the rest.

The honest exception: if you don’t yet know what’s reusable, we say so, and build a lighter clickable model instead, one we tell you up front is meant to be thrown away.

Questions you’re probably asking

How much does a working prototype cost?

A Prototype is a fixed $7,500. Nothing moves that price: one price, three weeks. You get a working prototype you own outright.

How long does it take?

About three weeks.

Do I own what you build?

Yes, outright. The source is the start of your real app, in code you own from day one, and you never pay twice for it.

Is this a throwaway demo?

No. We build the one slice that proves it as the first increment of production, not a mockup to be binned. The honest exception: if you don’t yet know what’s reusable, we say so and build a lighter clickable model instead, one we tell you up front is meant to be thrown away.

You finished a Starter. What now?

When you’re ready, it grows into a Partnership. It takes one of two shapes.

    Custom Build

    We build it with you.

    From $20,000

    The Prototype is the first real piece of your product, and it’s yours. A Custom Build picks up exactly where it left off: same code, same team, the rest of the app. You never pay twice for the slice.
