How we build
The same method on every project, tooled end to end: we describe and you approve before we code, we reuse components already in service elsewhere, and the AI agents that help us work under written, enforced rules.
We describe, you approve, then we code
Before the first line of code, each feature is described on one page: what it does, what it doesn't, and the concrete criteria that will tell whether it works, for example "importing a 5,000-row file takes under 30 seconds and flags every rejected row". You read it, you approve it, and that page is the reference throughout construction. If scope grows along the way, we tell you, with options priced in time and cost, including "not worth it".
Before construction, you click through a mockup of your future tool, screen by screen, filled with invented data.
We reuse what already works
Our applications share one technical foundation and a library of components already in service with other clients: secure sign-in, permissions, Excel file import, approval workflows, dashboards, connection to an ERP or a point of sale, AI enrichment of product sheets. Each component has been tested and fixed in real conditions before it reaches your project. The result: less time, fewer defects, and code any developer can read.
AI agents write the code, an engineer checks it
We develop with AI agents that write a large share of the code. They don't work freely: every project carries a written rulebook (scope, security rules, code style) they must follow, and automatic checks reject their changes the moment a rule is broken. Every change is then reviewed by an engineer before it ships. Inside your applications, same logic: the AI assistant drafts a reply, an email or an entry, and you approve before it acts.
Security and compliance checked automatically
Three rules are never up for debate: every screen and every record checks that the user is allowed to access it, not just that they are signed in; if a check cannot be performed, access is denied; no password or key is ever written in the code. An automatic test walks every entry point of the application before each release and blocks it if one is unprotected. For AI-powered features, we document their classification under the EU AI Act and keep that file current in the project.
We operate, you use
Your application runs on our servers, under a subscription that covers hosting, AI models, connections to your tools, updates and support. No server to manage, no licence to track, no update to schedule.
On every project, systematically according to your needs
Hosted in Europe
Servers, files and database in the European Union, for example in Paris and Frankfurt. Data encrypted on disk; a full backup every night, itself encrypted and stored somewhere other than the application.
Tested button by button
Three levels of tests, replayed automatically on every change: each function alone, then the functions together with a real database, then full journeys in a driven browser that clicks every button, fills every form and checks every screen the way a user would. A single failing test blocks the release.
Monitored continuously
A check constantly verifies that the application and every service it depends on (database, email, AI model, connectors) are responding. In case of an outage we are alerted immediately on our phones, and a regular status report keeps us informed.
Measured, not assumed
Every call to an external service and every call to an AI model is recorded with its duration, outcome and cost. A slowing service, a rising error rate or a drifting AI bill shows up on our boards before you notice, and we act before the outage.
Identities masked for AI
Before anything is sent to an AI model, names of people, places and companies are replaced by codes ("Client 12", "City 3"). The lookup table stays with us: the model never sees the real identity, and you get the real names back in the results.
Released without downtime
A new version starts alongside the old one and only takes over once it responds correctly. If it fails, the old one keeps running, and we know how to roll back within minutes.
Ready for the unexpected
Every night the backup is re-read and decrypted to confirm it is usable. A continuity kit (code, configuration, restart procedure) is kept encrypted outside the application, to restart elsewhere if the host fails.
Documented to last
Every project carries its infrastructure map (which servers, which services, which settings) and its test matrix (which feature is tested, at which level), updated with every change. An engineer who has never seen the project can take it over.
If custom development is not the right choice for you, we say so, and point you to an existing tool.
