The laboratory

Three objects running on real data. They show how we build: public feeds, code of our own, nothing that cannot be checked.

Live

A studio that talks about data should show some. These figures come from open sources, live, with no key and no cookie.

Each tile queries a public source when the page opens. If a source does not answer, the tile says so and invents nothing. That is the standard we hold your dashboards to.

The globe is centred on the Riviera and turns at the Earth's real speed. Drag it to spin it: it comes back on its own. Start the radio from the menu and the stations appear here, grouped by place with their count; tap a point to listen, tap again for the next one.

Figures that work

A dashboard is only worth having when it is connected to your real tools, and when it can say that it does not know.

Below, an example of what we install for clients: sales, margin, projected cash, sales funnel. The data is simulated, the code is the one we deliver. At your place it connects to your accounting, your CRM or your exports.

What we have already built

Property price estimation from notarised sales

Confidence index, dispersion, outliers and a map of sales, built on French DVF data. Postgres, PostGIS, MapLibre.

Statistical certification of trading strategies

Backtests, rejection thresholds and continuous execution on a terminal that runs 24/7. TypeScript, exchange connectors.

Documents generated by a language model, checked against a schema

Structured PDF generation through the Anthropic API, with field validation before rendering. PHP, MariaDB.

Test your site in ten seconds

A free express check, no sign-up: the first things we look at when a site is handed to us.

What you get, right away

Speed and weight

Response time and the weight of the home page. Past two seconds, one visitor in two leaves before seeing your offer.

What Google sees

Title, description, main heading, declared language, language versions. This decides how you look in results, and increasingly in AI answers.

Trust and compliance

HTTPS, cookies set before any consent, third-party scripts that follow your visitors. These are the points that cost money under inspection.

Basic accessibility

Phone readiness and images without alternative text: two simple measures that affect every visitor.

  • Nothing to do
  • Improve
  • Fix

Analysis runs from our servers, home page only, nothing is kept. The check keeps nothing and commits you to nothing. If a point worries you, describe it to us: the written reply comes within 24 hours.
