Web Development & Digital Products

Three spreadsheets contradict each other, the dashboard has been lying for six months, and management decides on whichever looks most up to date. That is when we get the call.

TECHNOLOGY · DATA · AI
Digitalise & code

Websites, platforms, data systems and artificial intelligence — built to be operated, not merely delivered. What leaves here must run on an ordinary machine, be readable without us, and say what it does not know rather than invent it.

IN ONE SENTENCE

Altimetria's Development & Technology practice builds data systems and digital products: databases, platforms, business applications, automations, security. We build for others what we built for ourselves — a platform operated in production every night, checked by its own guardrails, where every figure on screen knows where it came from. Not a demonstration.

Four domains, four deliverables

DomainWhat we instructWhat comes out
Development & Product DesignWebsites, web and mobile applications, e-commerce, business software. UI/UX lives with the code: what is drawn is what ships to production.Operable product
Data & Artificial IntelligenceData engineering, AI integration, automation, dashboards. Every figure on screen knows where it came from, and says so when asked.Decision instrument
Information Systems & CloudIT architecture, cloud, DevOps, migrations, ERP and CRM: a patchwork of tools replaced by a system an in-house team can run alone.Operable system
Cybersecurity & AuditTechnical audits, penetration testing, data protection, compliance. Least privilege, audit trail, a recovery plan actually tested — and real exposure measured before proposing a single piece of work.Contained exposure

This is the division that designed MERIDIAN. It does not sell a website: it sells the engine that answers — and what it refuses to say when it does not know.

DEV & TECH · WHAT WE HAVE BUILT

ALTIMETRIA
Shipping a product, not a mock-up

Development and product design: an interface is judged on an ordinary machine, not the one that built it. Our screens stop when reduced motion is requested, work from the keyboard, and state that they are loading rather than sitting blank.

An engine, not a directory

Data and artificial intelligence: directories list. Here sources cross — a contract joins its buyer, who joins their history, which joins companies and their situations. Insight comes from crossing, never from the list. And an empty field reads “N.F”: zero would be an assertion, and a false one.

The data stays with its owner

Information systems and cloud: we can run a database holding billions of rows on a desktop machine, and the same one online when it has to be shared. What decides is who needs access — not the fashion of the moment.

Personal data does not leave the building

Cybersecurity and audit: our databases contain people's names, because public data does. None reaches the public site, no public export carries any, and a page that let a whole file be downloaded would be a defect — not a feature.

A project we ran on ourselves first

This site is our first client. It was brought up to date one layer at a time, the security audit re-run at every step, with no forced upgrades: the most direct proof of seriousness is the one you are looking at. The same workshop serves our films, our sites and our applications.

The brand workshop: compose the interface, it redraws itself

Eight ready mechanisms, seven controls, one interface that answers on click. It is the move we offer every brand: start from a mechanism, change what does not look like it, and receive a system — not a mock-up.

Eight design mechanisms, adjustable on screen: palette, typography, density, corners, motion.

The Dev & Technologie method

01

Design

Sober architecture, explicit choices. Complexity has a price; we only buy it when it pays.

02

Build

Short iterations, code that runs. A demonstration beats a promise.

03

Prove

Tests, load, security, disaster recovery: a system is judged under constraint, not in a demo.

04

Operate

Run, measure, guardrails that execute on their own. A product lives — it is never “finished”.

What we deliver

Platforms & SaaS in production, with their exit plan written
APIs & integrations with the tools already in place
Data systems: one contract per flow, end-to-end lineage
Dashboards that carry their sources — every figure says where it came from
Automation & AI integration — cited, bounded, able to abstain
Technical & security audits: exposure measured before any work is proposed
Disaster recovery actually tested, not merely documented
Architecture & IT master plan
Skills handover — an in-house team that runs it without us

What we build for ourselves

We build our own data and AI platforms. One of them today joins over two million relationships between companies and French public buyers, checks itself every night, and applies one simple standard: every figure shown must be explainable.

Something we built, not something we sell — measured in our own databases on 21 Sept 2026.

WHAT WE BUILD FOR OURSELVES
TYPICAL SCENARIO — ILLUSTRATIVE

Replacing a patchwork of tools with a system.

A wholesale and distribution business accumulates disconnected tools: sales management on one side, stock on the other, three spreadsheets in between. Data contradicts itself, teams re-enter it, and the dashboard has been lying for six months without anyone noticing. Dev & Technologie audits, draws the target architecture, then builds in batches: a data contract per flow — who owns it, which schema, what freshness is expected —, end-to-end lineage, automation, dashboards. Then hands over the keys, with the exit plan written on day one. The rule never changes: every figure shown must be explainable.
