Cofondateur Fractionné is a fractional C‑level marketplace matching French early‑stage startups with experienced operators (CFO, COO, CMO) on a part‑time, equity‑plus‑cash basis. Many French seed founders on r/Entrepreneuriat and in local Slack groups admit they lack expertise in finance, ops, or sales, but can’t justify a full‑time senior hire. Cofondateur Fractionné vets executives from scaleups and ETI, packages them into 2–4 days/month engagements, and standardizes contracts, vesting, and board reporting. - Target users: Seed to Series A startups backed by BAs, Bpifrance, or regional funds needing senior muscle to unlock next milestones. - Unique angle: France‑centric matching (taking into account JEI status, BSA‑Air, BSPCE, Crédit Impôt Recherche, and regional subsidies) plus portfolio‑style reporting for investors. - Monetization: 15–20% marketplace take rate on engagements and a SaaS fee for collaboration tools and templates. - Why now: Post‑2022 funding environment forces startups to be leaner and milestone‑driven, making high‑impact fractional roles more attractive than full‑time hires.
