Maison GR — MVP developmentQuebec City --:--

Your MVP,in production, not in a demo.

An MVP is not a mock-up: it is the smallest version that solves the problem for real users. We scope it, build it and ship it, then measure what it teaches.

Who it is for

For founders who must validate an idea before raising, and for SMEs testing a new product.

01What we build

The scope,plainly.

  1. aScope definitionWhat goes in the first version, and above all what does not.
  2. bClickable prototypeTo test flows with users before coding.
  3. cFirst version in productionAccounts, payment where relevant, analytics: a real product, not a demo.
  4. dTraction measurementKey events tracked from launch, to know what to build next.
  5. eFoundations that holdAn MVP you grow instead of throwing away after validation.
  6. fPost-launch iterationsFix, remove, add based on what users actually do.

03Proof

Already done,in production.

Rehearse and Resistaa were launched as real products between April and June 2026, then grown based on usage. It is the same method we apply to our clients' MVPs.

04Approach

Howwe move.

  1. 01

    One week of scoping

    Hypotheses, target users, core function, success criterion.

  2. 02

    Prototype

    Validated with real users before the build.

  3. 03

    Tight build

    Only what serves the hypothesis being tested.

  4. 04

    Launch and measure

    Go live, track, decide: continue, pivot or stop.

05Frequently asked questions

Before youwrite to us.

01How much does an MVP cost?

The market publishes $15,000 to $30,000 for a prototype and $40,000 to $80,000 for a sellable MVP (Modall). Our costs page details these figures and their sources.

02MVP or prototype: what is the difference?

A prototype tests an idea, often without production code. An MVP is a real product online, used by real customers, solid enough to grow.

03Should we start with no-code?

Sometimes, to test demand very early. Once the product must be secure, multilingual or sold by subscription, custom development becomes cheaper over time.

04What happens after the MVP?

The first version's data tells you what to build next: continue, pivot or stop. That is the decision the MVP must make possible.
