# App Prototype in One Week

The core flow of your idea, clickable, on the real stack and a live link, in one week. $997, one payment.

**What's included:**

- ✅ Senior developer
- ✅ Full code ownership
- ✅ Done in one week
- ✅ One price, paid once
- ❌ Meetings overhead
- ❌ Scope creep
- ❌ Hourly billing
- ❌ Billing surprises

**Get started:**

- [Start a Project](https://varstatt.com/start?cta=agent)
- [Ask Jurij](mailto:jurij@varstatt.com)

## Problems

- **An Idea Nobody Has Clicked** Users react to a screen, not a deck.
> I can't tell if anyone would use it.

- **A Quote for the Whole Build** Agencies price the full product before anyone tries it.

- Months of spend before the first user

- **A Demo You Throw Away** A no-code mock the real build starts over from.

- Built on the real stack, it stays.

- **One Risky Unknown** An AI result or an integration nobody has tested.

- That part gets tested first.

## A Prototype That Isn't Thrown Away

| Route | What It Is | The Catch |
|---|---|---|
| Design Mockup | Clickable screens in a design tool | Nothing real behind the clicks |
| No-Code Prototype | A working demo on a builder | The real build starts over |
| Agency Discovery Phase | Workshops and a spec | Weeks and a big quote before anything runs |
| **This Week** | The core flow on the real stack | One flow, not the whole product |

## What You Get

- **A Live Link** The core flow, clickable: sign up, do the one job, see the result.

- **The Real Stack** Built where the MVP will be built, so nothing is thrown away.

- **The Risky Part Tested** An AI result or an integration, checked first when it's the risk.

- **Your Call** Show it to users, then stop or [build the MVP on it](https://varstatt.com/x/founders/mvp-development).

## Prototype or MVP

| | **Prototype** | MVP |
|---|---|---|
| Answers | Does it make sense to users? | Will people pay? |
| Time | One week | Six weeks |
| What Lands | The core flow, clickable, on a live link | Sign-in, payments and the one job, live for real users |
| The Code | Answers one question; kept or thrown away | Becomes the product |

Ready to launch? [MVP development](https://varstatt.com/x/founders/mvp-development) runs six weeks.

## Who It's For

**Right For**

- Founders who need something users can click

- Founders about to show investors or first customers

- Founders unsure the risky part can be built

**Better Elsewhere**

- A full product, launched *The six-week MVP*

- Design only, no code *A product designer*

- A stack outside JavaScript and TypeScript *A developer of that stack*

## How It Works

A simple, predictable and transparent process that eliminates development headaches.

1. **Book** — Pay once and you get a dedicated task board. Describe the one job your product does.
2. **Setup** — I pick the stack and set up the repo and accounts in your name.
3. **Plan & Develop** — I build the core flow on a live link, the risky part first.
4. **Review & Refine** — You click through it during the week. I revise until you're satisfied.
5. **Progress** — You approve the prototype. Show it to users, then stop or start the MVP.
6. **Maintain** — The MVP builds on the prototype, by the week.

## FAQ

### What does a prototype cost?

$997, one payment, for one week. The [MVP](/x/founders/mvp-development) that builds on it runs at $997 a week after that.

### Do I need a proof of concept first?

Only when the risk is technical, like an AI result or an integration. Then the proof of concept goes inside this week, before the rest of the flow.

### What fits in one week?

One flow: sign up, do the one job, see the result. Payments, admin and edge cases wait for the MVP.

### Do I need to be technical?

No. You describe the job; I make the technical calls and explain them in plain words.

### Who owns the prototype?

You do: the code, the accounts and the live link are [yours from day one](/principles/philosophy/client-owns-everything).

### What if users don't want it?

Then you've spent $997, not a build. Work that isn't right, I revise until you're satisfied.

### How do I get started?

Fill in the [project form](/start?cta=prototype-development-faq), about a minute: describe the one job your product does. I reply the next working day.

## [Founders × Varstatt](https://varstatt.com/x/founders)

Prototype fits founders best: people building a product without a technical co-founder.

- **[Fractional CTO](https://varstatt.com/x/founders/fractional-cto)** "No one makes the technical calls." The calls and the code, every week.

- **Prototype (this page)** "An idea nobody has clicked." The core flow on a live link in one week, one payment.

- **[MVP Development](https://varstatt.com/x/founders/mvp-development)** "An idea, ready to test with paying users." The smallest real product, launched in week 6.

- **[SaaS Development](https://varstatt.com/x/founders/saas-development)** "Ready to build the whole product." Launched in week 6, then built on real feedback.

- **[PWA Development](https://varstatt.com/x/founders/pwa-development)** "Phones, without three separate apps." One app that installs from a link.

- **[Vibe Coding Rescue](https://varstatt.com/x/founders/project-rescue)** "An app stuck, unsafe, or left by its developer." The bleeding stopped and a plan, in one paid week.

- **[App Modernization](https://varstatt.com/x/founders/app-modernization)** "A V1 that holds the product back." V2 built beside it, until every user moves.

- **[Tech Due Diligence](https://varstatt.com/x/founders/tech-due-diligence)** "A raise or a purchase on the calendar." What diligence will find, ranked, in one paid week.
