Bretagne's startup funding activity is anchored heavily in Rennes, which hosts the majority of the 29 companies in this dataset — from the $92M Series C raised by Unseenlabs (privacy and security, February 2024) to earlier-stage bets like HouseBase ($860K angel, May 2024) and Ochy ($750K pre-seed, December 2023). Cesson-Sévigné surfaces repeatedly as a secondary cluster, with BrightClue, JABI, GLIMPS, and Quortex all based there.
Sector breadth is a defining characteristic: artificial intelligence accounts for five companies including RainPath (seed, $3M, July 2025) and GLIMPS (Series A, $7M, 2021), while health care draws recurring growth-stage rounds from Biosency ($8M), Follow ($4M), and Invivox ($8M) across 2022–2023. The top three rounds by size — Unseenlabs ($92M), Quandela ($54M Series B, November 2023), and Cailabs ($27M Series C, December 2022) — indicate that later-stage capital is reaching the region alongside the high volume of seed activity visible through 2025.
