Raising our seed round
Software that takes the busywork off small teams.
Sonarbee is a two-founder startup at Station F. We build focused products for people who run things: Plongiciel for dive clubs, and Sonarbee AI for the work no one wants to do by hand.

01 · What we build
Two products, one small team.
Plongiciel already runs dive clubs. Sonarbee AI takes the busywork off everyone else.
Plongiciel
LiveManagement software for French dive clubs and centres. Bookings, outings, dive teams, payments and members in one tool: less time organising, more time by the water.
- Online bookings and outings
- Dive teams and member records
- Payments and the club's website
Sonarbee AI
Private betaAssistants for small teams. They draft the replies, fill the forms and chase the follow-ups; a person approves every action before it runs.
- Works in the tools you already use
- Every action waits for approval
- Sources shown with every answer
02 · How we work
Listen, build, stay on watch.
- 01Week 1
Listen
We start with the people who will use the product, not with our stack. A short discovery gives us a shared map of their week.
- 02Every week
Build
Working software every week. Users steer while steering is cheap, and nothing ships that they have not tried.
- 03After launch
Stay on watch
After launch we keep listening: support, monitoring and the next iteration, so the product keeps earning its place.
03 · Founders
Two founders, one desk at Station F.
Small on purpose. You talk to the people who write the code.
Mathis Estève
Co-founder, engineering and operations
Runs everything under the products, from the edge proxy to the release pipeline, and makes sure what ships stays up.
