01Proof

Proof,not promises.

Everything we sell, we did for ourselves first — with our own money, our own users, and our own bills.

01

3

SaaS in production

Signum, Resistaa, and Rehearse, launched between April and June 2026.

02

5months

To build Signum

The equivalent of 12 to 24 months of conventional engineering.

03

~1,100

Automated tests

On Signum: security, accessibility, and full user journeys.

“No report without code. No slide without a decision.”

Every figure can be checked during a technical review.

02Our products

The roomsof the house.

Every Maison GR product is a room in the house, with its own identity and status. We build them, we run them, and when another owner can grow one faster, we sell it.

03Work with us

Three ways towork with us.

i01

Build with us

Your product, designed and built to measure: B2B website, SaaS, mobile app, or AI integration. The code is yours.

ii02

Start from one of our products

Our platforms are built to be adapted. A version of Signum for your industry or country, in weeks rather than months.

iii03

Acquire a product

Some of our products are for sale, with code, domain, brand, and transition support included.

05Our method

A clear method,from framing to launch.

Each step reduces risk and moves the product toward a real production launch.

  1. 01

    Precise framing

    Goals, risks, budget, users, constraints, and the first useful version.

  2. 02

    Design that decides

    Flows, content, interface, and motion aligned with conversion and real usage.

  3. 03

    Robust foundations

    Modern stack, security, performance, observability, and documentation from day one.

  4. 04

    Measured launch

    Production, SEO, analytics, monitoring, and post-launch iteration.

06Why Maison GR

A studio that liveswith what it builds.

We build, run, and pay for our own products. That is what makes our advice concrete.

  • 01

    A senior team, no intermediaries

    You talk to the people who design and build.

  • 02

    We pay our own bills

    We know what a product costs after launch.

  • 03

    We live with our decisions

    A bad architecture is one we maintain ourselves.

  • 04

    We know how to sell software

    Pricing, trials, retention: tested on our own users.

How we build

AI agents. Senior engineers who decide.

  1. AI agents

    Write fast

  2. Senior engineers

    Review and decide

  3. ~1,100 tests

    Check every change

07Straight answers

What people ask usbefore signing.

01Do your products come before my project?

No. When we take on an engagement, it comes before our own products, and that's written into our agreement.

02Who owns the code?

On a custom build: you do, fully, at final delivery. If your project starts from one of our products, a clear license spells out what's yours.

03Could you launch a product that competes with mine?

No. We commit in writing to never launch a product that competes with an active client's.

04Will my idea stay confidential?

Yes. We sign an NDA from the first call if you want one.

05You build with AI. Does quality hold up?

AI agents write fast. Our senior engineers review, test, and decide. On Signum, nearly 1,100 automated tests check the code on every change, including security and accessibility.

06Why sell your own products?

Because a product deserves the owner who will grow it furthest. Our model: build, run, and sell when a dedicated acquirer can take it further than we can. Signum is ready for that owner.
