Click through your app before you commit to building it

Tell us the idea, the spreadsheet you want to replace or the job you're hiring for. We build a working prototype of the main screen first, then quote the rest at a fixed price.

Fixed quote within 24 hours. Pay only against approved stages.

Start with the free prototype

Describe the product. We build a clickable prototype of its main screen so you can test the idea with real users before a single invoice.

Who it's for

  • Funded startups that need an MVP without hiring a team
  • Companies running operations on spreadsheets
  • Teams who'd rather buy a fixed-price build than make a hire

What you get

  • A working prototype and written spec
  • MVPs paid 50/30/20 against approved stages
  • Tests and code review on every stage
  • Your repository, your cloud account, your code

How it works

  1. Say it. Tell us what you need in plain words — a message, a call or a voice note.
  2. Shape it. We send a plan and a fixed quote within 24 hours.
  3. See it. You watch it being built and approve each stage before you pay for it.
  4. Own it. The code, the domain and every account are yours.

Questions

What is in a Prototype Sprint?

A working prototype of the main flows, a written specification, and a fixed quote for the production version.

How is an MVP priced?

As a fixed price split into stages. You pay each stage only when you approve it — 50% to start, 30% and 20% at the agreed milestones.

Who owns the code?

You do, from the first commit. It lives in your repository and your cloud account.

Can you take over an app someone else built?

Yes. We review the code first and tell you plainly what to keep, fix or rebuild before quoting.

Where is the team?

A dedicated remote engineering team working US business hours, with real overlap for calls and reviews.
