We build your custom software & AI systems that boost your profitability
AI built in where it replaces real hours, never as decoration.
We build the custom infrastructure that unlocks the value locked in your teams, your data and your know-how, and turns it into growth and a real competitive edge: more clients, a better experience, experts who create instead of repeat. Powered by AI, it evolves by your side, just like us.
The digital transformation
Your tools hold your growth back. Soon, they propel it.
Before
What's blocking your growth today
- 47%Of your know-how lives in one person's head, never shared or leveraged.
- 15h/weekOf repetitive tasks that eat your teams' time, instead of the high-value work that would grow you.
- 2 monthsTo train a new employee on your undocumented processes.
- 3h/dayTime wasted making tools that don't talk to each other communicate.
- 8 SaaSOn average, 5 of which you only use at 20% of their potential.
After
What you get back
- Built for youSoftware built around your operations, not a generic SaaS you use half of. Every view, every number, every automation exists because your business needs it. You decide right, at the right moment.
- One cockpitOne screen that centralises your data in real time. The right info at the right moment, no checking 4 tools, no calling the expert who’s on holiday. It updates itself, and it tells the truth.
- 100 % yoursThe code belongs to you, you depend on no one. And we train your teams to run it, all the way to autonomy.

Restaurant Group · Saint-Étienne
Chromosome
How a restaurant group in Saint-Étienne runs all its operations on software it owns, and gives its teams back 14 hours a week for what truly matters: their guests.
It changed the way we run everything, we couldn't do without it now. The time and clarity we've gained are huge, and the team is far more at ease.

Operations on software they own
We give you a free diagnostic, no email, to see where your hours go and where to unlock value.
60 seconds, quantified, 3 prioritised levers. No commitment.
Take the free diagnostic →Our services
Real expertise, forged in the field.
We replace ill-fitting generic tools with custom software you own. AI and automation are embedded only where they free your experts from repetitive work, so they create value instead of losing it.
Our method
A clear method, no surprises.
You always know where we are and where we’re headed. Four steps, one concrete deliverable at each. And the job isn’t done until your teams are autonomous.
The Diagnostic: mapping & analysis
We map how your whole business runs, from a prospect’s arrival to a client who refers you: acquisition, delivery, internal management. We examine every step in detail and as a whole, to pinpoint where you lose time and money. You leave with a clear map of your workflows, and a first clickable prototype of your future tool, even if we don’t work together.
→ 1 to 15 days
Then: custom build
We build the software, portal or cockpit tailored to your processes, and unify your data into a single source, live in real time. We add AI and automation only where they save you real hours. A usable MVP is ready in under 30 days, the full build in 30 to 60. Price and timeline fixed up front, a check-in every week.
→ 30 to 60 days
Then: training & support
We test everything before launch. Then we train every person on your teams, from the executive to the field, until they use it on their own, without us. Nobody is left behind.
→ Until full autonomy
Finally: optimise & improve
After a few weeks of real use, we look at what works and adjust. And if you want, we stay by your side to grow your software at your pace.
→ Retainer
Why us
What makes us different.
Result-driven, zero patching
We first ship what’s already proven and pays off, an 80/20 logic, then we optimise. Only solid things that run. Never a trendy tool, a band-aid or a half-built thing.
Built to last
We’re here for the long run. We build your solution truly around your processes, workflows, teams and trade, so it’s as effective as possible and lasts over time. Not a one-off: an infrastructure that supports you for years.
Speed & reactivity
A reply in under 15 minutes during onboarding week, a weekly video check-in, continuous feedback. We listen, adjust and execute fast, and you watch the software move forward.
You stay autonomous
The code and infrastructure are yours. Before we leave, we train your teams to use and evolve them: never stuck, never dependent. And we stay available if you need us.
The results guarantee
We agree upfront on clear, measurable objectives, and we keep working until they’re met. A commitment that also covers deadlines, code ownership and quality.

FAQ
The honest answers.
Custom business software: the internal platform that runs your operations. Unified database, dashboards, client portals, internal tools. AI and automation are integrated only where they replace real hours of work, not as decoration.
4 to 8 weeks for the initial build, depending on scope. We agree on a fixed scope and a fixed delivery date before writing a line of code. Weekly check-ins, monthly demos, no scope creep, no surprise invoices. Pricing is shared on the discovery call so it matches your real needs.
Yes. It's monitored around the clock, backed up automatically several times a day, and we step in fast if anything goes wrong. In plain terms: it runs, and if there's a glitch it's fixed before it gets in your way. After the first 3 months, you choose: we keep handling maintenance, or we hand everything over to your team with the documentation.
Wherever it saves real hours. The common ones: automated workflows (orders, invoices, follow-ups, internal handovers), predictive analytics (anticipate stock, no-shows, sales trends), document parsing (read invoices, contracts, forms), intelligent triage (sort, route, draft replies), autonomous agents that execute multi-step tasks across your tools, and conversational interfaces for your team or customers. We pick what's worth building for you, not everything because it's trendy.
100% of the code is yours and hosted on your infrastructure. Full documentation included. Any competent developer can pick it up. No subscription, no lock-in, no hostage situation.
Restaurants, consulting, construction, healthcare, retail: wherever there are recurring operations and real data flowing through them. The stack adapts. The method doesn't change.
It can, but waiting has a cost. 20% of European companies (10+ employees) already use AI in 2025, up from 13.5% a year earlier. Teams that integrate it into their core processes free up 20–30% of their working time (McKinsey), and SMBs that adopt it are 2× more likely to grow year over year (Salesforce). Every month of waiting is a month your competitors use to widen the gap, and time your teams keep spending on tasks a well-built system would absorb.
We use the most reliable, recognised technologies on the market: the same ones big tech companies rely on. Your data is hosted in Europe, protected and GDPR-compliant. And everything is yours: the code belongs to you, you're no one's prisoner. (For the curious: Next.js, Supabase, Claude API, Vercel, solid standards.)
