What founders installed, and what moved.

A rope-access marketplace, an energy-renovation marketplace, a heating installer putting tech into his installations, a tech company. Different models, the same bottleneck: everything went through the founder.

Cohort 1 and clients

How they did it.

tech

“Thibaut made me rethink, at a deep level, the way we work and delegate. He didn't show up with a ready-made recipe: he first understood our context, our constraints and our resources, then challenged me with very current practices adapted to our reality. What mattered most wasn't the technique. It was building a system that lets the team move forward with far more autonomy, without everything resting on me.”

Lorenzo Pellizzari · Founder · EponEdge

The story

Before: Every decision came back to him.
The decision: Start from his real constraints, then challenge how things were done.
What moved: A team that moves without waiting for his green light.

Douglas & Thibault · Founder and partner · Les Suspendus

rope-access technician marketplace

“We were 100% dependent on the founder.”

Douglas & Thibault · Founder and partner · Les Suspendus

+38% annual revenue, in 3 months

€650K at the end of June, just before the program; €900K at the end of September (rolling 12 months).

The story

Before: Every sale went through Douglas. When he wasn't there, technical questions waited.
The decision: Take every simple quote out of his hands: standardize them, then hand them to the team.
What moved: 75% of quotes go out without him. The team tracks three numbers every day, margins are read by job type, and a recurring offer is ready.

“I was a bit overwhelmed […] Now I see things much more clearly.”

Guy · Founder · Woommy

3 weeks to build and automate his quoting system

Before: up to 4 hours per quote, and around twenty waiting.

The story

Before: Alone between job sites, quotes and admin.
The decision: A fast quoting tool, then a first hire.
What moved: The quote goes out at the first meeting. Guy is preparing his hires, and his installations carry a tracking QR code.

The story

“A hard worker like I've rarely seen: he gives 100% to his project and knows how to surround himself with talented people. A CEO who combines genuine humanity with sharp analytical rigour and a customer obsession. He brings out the best in everyone.”
Olivier DanniauEx-CCO of Sortlist · Founder @ Sparkway

“What struck me most was how involved he was, strategically and humanly. After a conversation with Thibaut, people walked away more motivated, more aligned, with a much clearer view of where the company was going.”
Cristian IordanFounding Product Designer @ Lette.ai · 5 years at Sortlist

“What stands out is his genuine availability and his commitment to building something meaningful — not just for the business, but for the people around him. A real ability to bring out the best in his team.”
