We’re thrilled to introduce HX25, our 2025 batch of 10 startups - and the first annual batch to span all three tracks: Start, Sprint, and Scale.
It’s the first time these tracks come together in a single cohort, reflecting our evolution into a multi-stage entrepreneurial platform: creating companies from scratch, accelerating pre-seed startups, and partnering with profitable businesses to help them scale into category leaders.
On the Scale side, Partner Augustin Celier has partnered with two profitable vertical SaaS companies, working hands-on to help them become category leaders over the coming years. The goal is to expand beyond their current segments to serve much larger portions of their markets.
We also kicked off our acceleration program, Sprint, with three companies in our European Defense & Sovereignty cohort, led by Guillaume Lerouge. Sprint supports pre-seed companies helping to secure Europe’s future, with new members to be announced soon.
And in our long-standing startup studio activity, Hexa Start - where we create companies from scratch alongside founders - Partners Florent Quinti, Matthieu Vaxelaire, and Ugo Vollmer have launched five companies this year, leveraging AI agents to solve problems across B2B buying, pentesting, user engagement, and more.
Without further ado, let us introduce the 2025 Hexa batch:
