Fair field conditions. Weekends at home, accommodation and meals covered, travel and site allowances.

Scale-up momentum. A €15M Series A (July 2026) funds industrialization and the ambition of a fleet of units in France and Europe.

A small, senior team. Direct access to the founders, and field feedback that genuinely changes the design of the next units.
