Hexa (eFounders) is a pioneer and leading startup studio born in Europe that designs, builds and launches startups in the B2B and SaaS space.
We have created more than 35+ companies (including 3 unicorns), combining +230 m€ ARR and having raised c. 750 m€. Our portfolio includes : Front, Aircall, Spendesk, Yousign, etc.
We’re now launching a new initiative to finance and support existing startups:
⚡Today, many founders are already building promising startups — but without the right capital, peers, or guidance, too many stall before they truly take off.
At Hexa Sprint, we’re on a mission to change that: we back founders who’ve already started building, helping them accelerate from 1→ 10.
We believe that early teams deserve the same unfair advantages as studio-born startups — expertise, network, and rhythm — to move faster and smarter.
We do this by investing €500k as their first check, surrounding them with sector experts and a tight cohort of peers, and giving them access to Hexa’s collective playbooks from 50+ companies.
Our ambition is simple: turn great beginnings into exceptional companies.
