Project lead, every week
Runs your raise from the first call to the signed term sheet.
His outreach engine
Why it changes the gameA fundraising hire takes months to find and has never sat on the investor side. Yoann has, 47 times, and co-founded Climentum Capital.
Leadership coach
Called in for co-founder tension, pitch presence and the big meetings.
Why it changes the gameInvestors buy the team before the numbers. Ferdinand works on it from week 1, something no Series A company can hire for.
Deck and visuals
Called in for the investor deck, weeks 1 to 3.
Why it changes the gameA senior designer is a full salary for a deck you need once per round. Sera delivers it in three weeks.
Comms and story
Called in before go-to-market and for the announcement.
Why it changes the gameA comms hire needs months to learn your story. Laura shapes it in weeks, for the moments investors actually see.
Chief of Staff
Called in once meetings start, until the money is in.
Data room, ready for diligence
Why it changes the gameA Chief of Staff search takes months. Joann runs your pipeline from week 4, so you stay with investors, not admin.

Pricing
Pick from the line-up
The alternative
Full-time hires. Months of recruiting, and salaries that run long after the round closes.
All-Star costs a fraction of full-time hires and is built to deliver ten times the value. One fixed fee for what you pick, agreed in writing. Never a percentage of what you raise.
Book your assessmentFAQ
All-Star is the Series A and B program by Climate Insiders. An all-star bench of senior experts, led by Yoann Berno, that you staff à la carte: fundraising, leadership, story, design or operations, only where your company feels stuck, for as long as you need them.
Category leaders in climate, energy, industry, materials, food and deeptech, or the ones we will help become one. Venture-backed and raising a Series A or B, typically €5M to €50M in equity, debt or both.
No. You raise it and stay in charge. We prepare you, run the machinery around you and open doors where the fit is real. We are not a broker or placement agent and never take a cut of what you raise.
You pick the experts and the time frame. We agree one fixed fee in writing before we start, a fraction of full-time hires. No success fees, never a percentage of what you raise.
No one honest can. We commit to the work: a strategy that holds up, diligence-ready materials, a targeted pipeline and senior people in your corner every week.
Yes. Yoann leads every All-Star engagement, runs the weekly session and joins the calls that matter. That is why we take a handful of companies at a time.
A closed, monthly circle of founders who have raised or are raising a Series A or B. Hot seats on real problems, real numbers shared in confidence, and warm introductions between members. Included while we work together.
You pick a 30 minute slot straight away. On the call you get an honest read and a clear yes or no. If yes, you get a written plan and fixed fee within 48 hours.
