Disclosed round sizes in Rennes are led by a single outlier: Unseenlabs raised $92M on 2024-02-27, which dwarfs the next-largest disclosed rounds in the list ($27M for Cailabs on 2022-12-08 and $13M for Check & Visit on 2023-05-26). Most other disclosed entries cluster in lower eight-figure amounts, with several rounds below $10M (e.g., Biosency at $8M on 2023-11-08; Invivox at $8M on 2022-03-23).
The timing also concentrates: the 14 shown rounds span 2020-03-10 (Energiency) through 2025-03-10 (Ostrea). Four of the 14 have the amount listed as undisclosed or “Series Unknown” style rather than a specific disclosed figure (Emova is “undisclosed”; five others are labeled “Series Unknown”), and the list mixes health care (Biosency, Follow, Invivox), security (Unseenlabs; OneWave), and energy (Sweetch Energy; Energiency) with a heavy share of technology-adjacent categories.

Frequently asked
What stands out most in disclosed funding size for Rennes—does one round dominate the rest?
Unseenlabs’ $92M round on 2024-02-27 is the only disclosed amount above $50M in the 14-row view, and it materially exceeds the next-largest disclosed amounts ($27M on 2022-12-08 for Cailabs and $13M on 2023-05-26 for Check & Visit).
How concentrated are these rounds by time when looking at the most recent window?
Between 2024-05-02 (HouseBase) and 2025-03-10 (Ostrea), the list shows four rounds: HouseBase ($860K, 2024-05-02), Unseenlabs ($92M, 2024-02-27), Emova (undisclosed, 2024-08-31), and Ostrea ($5M, 2025-03-10), indicating activity stays present rather than being a single spike.
Are there stage-label patterns that affect how comparable the rounds are?
Stage visibility is uneven: Emova is the only entry marked “undisclosed” on amount, and five entries carry a “Series Unknown” label (Biosency, Follow, OneWave, Simango, and Invivox is not labeled unknown—Invivox is Series A), which limits direct comparisons across stages.
Do any sectors appear repeatedly across multiple companies?
Health care shows up as a recurring theme with Biosency ($8M on 2023-11-08), Follow ($4M on 2023-10-06), and Invivox ($8M on 2022-03-23). Privacy/security and adjacent security also cluster with Unseenlabs ($92M on 2024-02-27) and OneWave ($430K on 2023-06-14).
Which entries look like outliers because they are unusually small within the disclosed amounts?
Among disclosed amounts, the smallest is HouseBase’s $860K on 2024-05-02. That round is far below the list’s main cluster (for example Ochy at $750K on 2023-12-19 and OneWave at $430K on 2023-06-14), while Unseenlabs at $92M on 2024-02-27 sits at the other extreme.
What does the city/street geography imply here—are there multiple cities or is it concentrated?
All 14 rows list the same city/location format: Rennes, Bretagne, France, spanning sectors from Consumer Goods (Ostrea) to Energy (Sweetch Energy at $6M on 2022-09-20 and Energiency at $5M on 2020-03-10), with no alternate city names in the shown dataset.
