Zero risk

You see your MVP before you pay a cent

Everywhere else you pay a deposit and discover the result at the end. We do it the other way round: we build your app, show it to you on video, and then you decide.

You pay once, by card. We apply your tweaks, put it live on your domain, and hand over the source code and every access, within 72 hours.

No deposit to chase, no invoice, no commitment. We delete the project on our side and your idea stays yours.

Where this model comes from. AI has made building fast enough for us to do it before we get paid, and an MVP you can watch running tells you more than a ten-page quote. The full details.

The problem

Testing an idea should not cost €10,000

Traditional agency, no-code agency, freelancer: getting an MVP or app prototype built costs between €3,000 and €35,000 and takes weeks. The result: most ideas never get tested. We built the offer that was missing: the complete demo version, live, at a price you can decide on today, and that you only pay for after watching it work.

The deliverable

What you get when you say yes

A product that runs on a real URL, that you can show to customers, users or investors as soon as it is live. You have already watched it working on video, so there are no surprises on delivery.

Your app, live

Deployed, reachable on a real URL, ready to be tested by real users. If you have a domain name, we connect it.

100% of the source code

The complete repository is handed over. No dependency on us, no hidden subscription: the product belongs to you, full stop.

Professional, responsive design

A modern, credible interface that renders perfectly on phone, tablet and desktop. Your testers judge the packaging too.

The core features

We build the heart of your product: main journey, forms, simple user accounts, demo payment. The essentials for testing, nothing decorative.

Full access, yours

Hosting, deployment, code repository: everything is created in your name or transferred on delivery. You leave with the keys, not a promise.

The handover guide

A simple document: how to change your app, make it evolve, and what to do if the test works out. You are never stranded.

How it works

Built first, paid after

For whom?

What a €299 MVP can be

Any product whose core fits in one clear user journey can become a testable MVP in 72h. A few typical formats:

SaaS demo

Landing + sign-up + the dashboard that shows your flagship feature. Enough to sell before you build.

Built in 72h

Marketplace

Marketplace or matching platform: profiles, listings, first contact. The core mechanics, testable.

Built in 72h

Booking / scheduling

Storefront + slot booking + email confirmation. Ideal for testing a local service or a B2C offer.

Built in 72h

Tool / calculator

Simulator, generator, comparison tool: something genuinely useful that captures qualified emails.

Built in 72h

Mobile app demo

A mobile-format web app, installable on the home screen: perfect for testing usage before investing in native.

Built in 72h

Investor demo

A clickable, live product for your raise or your board: infinitely more convincing than a slide deck.

Our method

AI brings the speed.
Experience brings the quality.

Yes, we build with AI. That is what makes 72 hours and €299 possible. But a tool does not replace the craft: scoping the right perimeter, structuring a sound architecture, reviewing the code and deploying properly. That is exactly where most "AI-generated" projects fail, and where we spend our time.

Already tried Lovable, Bolt or v0 and got stuck? We take your project over, finish it and put it live. See how it works →

  • Product scoping before any line of codeWe define what your MVP must prove, and cut everything else. That is the real secret of the 72 hours.
  • Code reviewed and structured by humansStandard, proven web technologies. No blindly generated spaghetti code, no proprietary lock-in.
  • A deployment you controlModern hosting, full access transfer. The day you want to fly on your own, everything is yours.
Pricing

One price, paid only if you like it

No quote and no deposit: one price, known in advance, that you pay after you have seen your MVP.

FAQ

The questions we get asked

Do you really build my MVP before I pay?
Yes. You describe your idea, we confirm within 24h that it fits, then we build your MVP without asking you for anything: no deposit, no card details, no signature. Within 72h you receive a video showing it working, screen by screen. You pay €299 only if you like it.
What if I don't like it?
You pay nothing and owe us nothing. We delete the project on our side and your idea stays yours. If it is almost right, tell us what is missing: often a tweak is all it takes.
Why a video and not a link to try?
Because the MVP becomes yours at the moment of payment: until you have paid, it is not live. The video shows every screen and every journey, with your content. If one detail makes you hesitate, ask and we will show you. And to judge the level of finish before you even write to us, ten complete demo apps are open to everyone.
Can I ask for changes?
Yes, once you have paid and before it goes live: copy, colours, images, order of screens, adjustments to a journey. A feature that was not in your original request, we discuss first, and we tell you straight whether it fits in the €299.
When do I pay?
After watching the video of your MVP, and only if you like it. You then receive a secure card payment link. Nothing is asked of you before that. Invoice provided.
What is an MVP, exactly?
MVP stands for Minimum Viable Product: the simplest version of your product that lets you test your idea with real users. It is neither a mockup nor a clickable prototype: it is a product stripped to the essentials, but real and live. It is the most effective way to find out whether anyone wants your idea, before investing months and tens of thousands of euros.
What can you actually build for €299?
A complete web product built around one main user journey: for example a landing page with sign-up and a dashboard, a simple matching platform, a booking tool, a calculator. What you see in the video is exactly what you get. What you will not get: a native mobile app or a product with 40 features, and we tell you within 24h rather than sell it to you.
Why is it 10 to 100 times cheaper than an agency?
First, AI, which saves us considerable development time. Second, a deliberately tight scope: an MVP is for testing, not for doing everything. Third, an industrialised process: proven building blocks, a well-oiled deployment, zero pointless meetings. An agency sells days of work; we sell an outcome.
Is it entirely made by AI?
No. AI generates, we scope, review, correct and deploy. The difference between an abandoned AI project and a product that runs is precisely that work. You get the speed of AI and an experienced product eye.
Do I really own the code?
Yes, 100%, from the moment you pay. You receive the complete source code repository, access to the deployment, and the handover guide. No compulsory subscription, no dependency on MonMVP. You can hand the next stage to any developer, or to us if you want.
Is 72 hours really doable?
Yes, because everything is designed for it: a clear scope from the start, proven technical foundations, and AI to speed up execution. The clock starts when we confirm your project fits, and the video arrives at most 72 hours later. Once you have paid, going live with your tweaks takes 72 hours at most, or you get a full refund.
What happens after delivery?
You test your MVP in real conditions. Then three possible paths: your test works and you invest in v1 (with us or with whoever you like, the code is yours); you pivot; or you stop having spent €299 instead of €20,000. In all three cases, you win.
Which technologies do you use?
Modern, standard web technologies (React/Next.js or equivalent depending on the project, managed database, cloud hosting). Concretely for you: a fast, secure product, and code any developer can take over. No exotic stack locking you in.
I started on Lovable, Bolt or v0 and I'm stuck. Do you take over?
Yes, and under the same rule. We take your project over on a copy, fix it, and you watch your app working on video. If it is right: €299, it goes live on your domain with its source code. If not, you pay nothing. Everything is explained here.
Are you a classic MVP agency?
No. A development agency bills for time spent (hence the €10,000+ quotes) and asks for a deposit before starting. MonMVP builds first and sells an outcome at a flat €299, which you pay after seeing it. AI and a tight scope make this model possible.
Do you work with clients outside France?
Yes. We are a French studio based in Bordeaux and work fully remotely. Scoping, updates and handover are handled in written English, which suits asynchronous work across time zones.
Do you build mobile apps?
To test a mobile app idea, we deliver a mobile web app: it runs from the phone browser and can be installed on the home screen. It is the fastest and cheapest way to validate usage. If the test works, you then invest in native, with real data to convince.
First feedback

They put their idea in real hands

Reviews from our French clients, translated from French.

"Done to test an app around physiotherapy. Honestly a very decent result, of course I still have things to tweak before considering a commercial launch, but it let me actually hold the thing in my hands, and it even gave me a few ideas for extra features. Thanks"

Olivier L. · physiotherapy app

"For a geolocation app to discover cities. Very happy with the result, it makes you want to take it further"

Maxim C. · urban discovery

"An app built on a really simple system I couldn't find anywhere... Now I have it! Deadlines met, very happy, if I need it again I'll be back"

Cindy O.

"I wanted a demo of a really basic showcase site for our practice. I didn't quite know what to expect, and I was very pleasantly surprised. Really professional, and it even makes you wonder whether you need an agency at all. In any case, thanks for the work, and on time"
