Startup MVP

Startup MVP. Fixed price. Live in weeks.

Wallion builds minimum viable products for startups that need to validate their idea with real users, fast. From idea to live in weeks. Written fixed price, not published grid.

What is an MVP

A minimum viable product is the simplest version of your product that solves the core problem and lets you learn from real users. It's not a prototype: it's working software in production, with real users paying or testing. The goal is to validate your hypothesis before building every feature — 80% of startups fail because they build something nobody wants, not because the code is bad.

What we build

Complete web software (frontend + backend + database) in production; authentication and user management; payment integration if you sell from day one; admin panel for you to manage the product; deployment on scalable infrastructure; basic metrics to measure usage; one main flow, not ten features. The MVP must answer one question: will people pay for this? or will people use it every week? If the answer is no, you pivot or stop — with a known and limited cost.

Written fixed price

Diagnosis €1,900 (2 weeks) — we define the MVP's main flow, prototype and lock the build price in writing. If you proceed, it's credited. Build: written fixed price based on the scope defined in the Diagnosis. Not the €6,900–14,900 band (that's for single-flow internal tools). An MVP is usually above that because it includes authentication, payments, admin panel and has to handle external users. Licence from €390/month — hosting, updates, support. Changes after the MVP are new fixed quotes, not open hours.

How we work

Diagnosis: you define what problem you solve, for whom and how you measure success. We cut everything that's not critical and give you a one-main-flow MVP with a fixed price. Build: we build it in 4–8 weeks and deploy it. Validation: you test it with real users. If it works, you add features (new fixed quotes). If it doesn't work, you pivot or stop — without having spent a traditional agency budget.

Frequently asked questions

Does an MVP cost €6,900–14,900?

No. That band is for single-flow internal tools. An MVP usually costs more because it includes authentication, payments, admin panel and has to work for external users. The Diagnosis (€1,900) gives you the written fixed price. <link>See internal tools</link>.

How long does it take?

4–8 weeks from fixed quote to the MVP being live with real users. You see progress every week.

What if the MVP doesn't work?

You pivot or stop, with a known cost. Better to discover in 8 weeks and €20k that your idea doesn't work, than discover it in 6 months and €100k. Most startups fail by building something nobody wants — the MVP minimises that risk.

What if the MVP works and we want to add more?

Each new feature gets a fixed quote in days. Never surprise invoices. Scope is always written down.

Why don't I own the code?

Because the price is a fraction of what traditional agencies charge. Wallion keeps the code and stays responsible for it running. Your data is always exportable, and escrow is available.
