# One-week coded prototype

Prove it turns one critical workflow of your product into a coded prototype with real behavior in five business days, for a fixed $4,900, with no tax added on top. It ends with a concise recommendation on what to build, and the full fee is credited to a build that starts within 60 days.

Also called: Prove it, Rapid prototyping, Prototype development, Coded prototype.

Bought through: Prove it (fixed $4,900, one week). Prices are in US dollars, with no tax added on top.

## Who it is for

Founders who need to see an idea working before they commit to a full build.

- **Founders before a raise or a pilot**, who want investors or a first customer to use the product with their own hands rather than watch a demo.
- **Teams with a risky workflow** that depends on live data, an outside service, or AI output that a mockup cannot fake.
- **Founders unsure what to build first**, who want a recommendation grounded in working software.
- **Teams inside larger companies** who need to show leadership a working version of a new idea before asking for a budget. [How that works](https://www.choie.co/enterprise).
- **Teams comparing studios**, who want to see how one works for a week before a larger commitment.

## The problems it solves

- **Mockups that hide the hard parts.** A clickable design only goes where someone drew a link, filled with tidy sample data. Code shows what happens with real input, errors, and slow responses.
- **Big commitments made on guesses.** A full build priced on an untested idea risks building the wrong thing well. One week of working software answers the riskiest question first.
- **Open decisions at build rates.** Every decision still open when a build starts gets made while paying build rates. A prototype week settles them, and usually lowers the build quote.
- **Not knowing what to do next.** The week ends with a written recommendation, so the next step is clear whether or not you continue with Choie.

## What you get

- One critical workflow, up to eight key screens or states, as a coded prototype with real product behavior.
- Delivered in five business days.
- One revision round, agreed at the day five walkthrough.
- One concise build recommendation: what to build next and what to leave out.
- The prototype code and designs, yours once the fee is paid.

User recruitment and formal usability testing are not included. The prototype is built to be used, so you can put it in front of your own users once it is delivered.

## How it runs

1. **Pay and book.** Pay the fixed $4,900 online through Stripe. A start date is confirmed within one business day.
2. **Day 1.** Pick the one critical workflow and name the screens and states it needs, up to eight. Decide what is out.
3. **Days 2 to 4.** Design and code the workflow together, as working software with real behavior, not a Figma mockup.
4. **Day 5.** Walk through the working prototype, agree the one revision round, and receive the build recommendation.

Your part is to be available for decisions during the week, most of all on day one. The same people design the prototype and write its code. AI and our own kit of interface components, motion and micro-interactions are why five days is enough, and a senior person reviews every line.

## Price and timeline

A fixed $4,900 in US dollars, paid in advance online. One week. Nothing is added on top.

If you start a full build within 60 days of delivery, the whole $4,900 is credited against it. Builds start from $19,000 and take four to six weeks, and the prototype usually lowers that quote because fewer decisions are left open.

## When not to hire Choie for this

- **You need several workflows tested at once.** The week covers one critical workflow. More than that is a [build](https://www.choie.co/services/mvp-development).
- **You need research with recruited participants.** User recruitment and formal testing are not part of the week.
- **The product is already decided.** If you know what to build, skip the week and go straight to a build.
- **You need a live product for paying customers now.** A prototype is built to test one workflow with a few people. A product that strangers rely on is a build.

## Common questions

### What is the difference between a coded prototype and a Figma prototype?

A Figma prototype is a set of linked screens that follows a planned path with sample data. A coded prototype is real software: it takes real input, handles errors, and behaves the way the product will. It shows the problems a clickable design hides.

### What happens after the week?

You keep the working prototype, its code, and a recommendation on what to build. If you start a build with Choie within 60 days, the full $4,900 is credited against it. If you do not, everything delivered is still yours.

### Can the prototype be tested with users?

Yes, it is built to be used. Recruiting participants and running formal tests are not part of the week, but you can put the prototype in front of your own users once it is delivered.

### How soon can the week start?

Once payment is made through Stripe, a start date is confirmed within one business day. Choie takes no more than two projects at a time, so the date depends on the work already booked.
