Expertise
Custom business tools
Software written for your processes: quotes, production tracking, a client portal, wherever your team loses time today. One week of immersion, then a release every week.
We start by watching how your team works, in the field and in its tools. The software comes next, edge cases included, where off-the-shelf software would force you into workarounds.
What clients tell us at the start
- We run five generic tools and none of them follows our real process.
- Our profession has rules that off-the-shelf software ignores.
- Our teams enter the same data three times.
- One critical spreadsheet keeps the company running, and nobody dares touch it.
What you have at the end
- Immersion in your business, observing your teamsone week
- Business rules handbook
- Clickable prototypes
- Development in weekly sprints
- Data migration
- Training and documentation
- Maintenance and ongoing improvements
Our tools : React, Supabase, PostgreSQL, Stripe, Yousign, embedded AI (Claude, Mistral), no-code (Airtable, Make) where the need justifies it.

The cost of custom software
For a fifty-user SME, a custom CRM can cost less over three years than the stack of subscriptions it replaces. It belongs to you, and it keeps working if you stop maintenance.
The calculation is done with your own figures during the diagnostic.
