Among the 50 most recent energy startups in France with disclosed amounts, the largest disclosed round is Electro’s $333M on 2025-07-24, which dwarfs the next-largest disclosed entries such as Neoen’s $885M on 2024-12-18 (the true maximum disclosed) and Waga Energy’s $180M on 2025-11-27, placing most rounds far below the high hundreds. The page also shows a tight geographic concentration: 2026 entries cluster heavily around Paris/Ile-de-France (e.g., Mirova $116M on 2026-06-01 and Koolboks $2M on 2026-06-05, plus multiple other Ile-de-France rounds like Jimmy $47M on 2026-03-10).
Temporally, most activity sits in the latest half of the listing window, with many rounds between 2024-11 and 2025-07 (for example, several $50M+ financings: ZE Energy $59M on 2024-11-05 and Spark Cleantech $35M on 2025-12-04). Stage mix is also skewed toward “Series Unknown” and “undisclosed” outcomes: “Series Unknown” appears on far more rows than labeled stages, while several rounds list “undisclosed” amounts (e.g., HysetCo on 2026-04-22 and Tiamat on 2024-01-15).

Frequently asked
Which disclosed rounds are the clearest outliers, and how far above the rest are they?
Neoen’s $885M disclosed round on 2024-12-18 is the dominant outlier versus the rest of the disclosed amounts (e.g., Waga Energy’s $180M on 2025-11-27 and Electra’s $333M on 2025-07-24 sit well below Neoen). At the low end, Immoblade’s disclosed $570K on 2025-01-06 is the smallest disclosed amount in the list.
Do recent rounds concentrate in specific locations (especially Paris/Ile-de-France), or are they evenly spread?
Paris/Ile-de-France is repeatedly represented, including major rounds like Mirova’s $116M (2026-06-01) and Jimmy’s $47M (2026-03-10), alongside smaller entries such as Koolboks $2M (2026-06-05) and Actility $17M (2023-12-07). Outside that cluster, large financings also appear in other regions, such as Waga Energy (Meylan, Rhone-Alpes) at $180M on 2025-11-27 and Energo (Loos, Nord-Pas-De-Calais) at $18M on 2024-05-16.
How concentrated is deal timing—are most rounds clustered in a particular window?
The list heavily weights the 2024-11 to 2025-07 period, where multiple high-dollar rounds appear (e.g., ZE Energy $59M on 2024-11-05, NHOA $58M on 2024-11-04, and EODev $50M on 2023-11-15 is outside but still late-2023; within the window also Spark Cleantech $35M on 2025-12-04). Recent entries extend into 2026, with the most recent being Koolboks on 2026-06-05.
What stage naming dominates, and how much of the page is missing disclosed amounts?
“Series Unknown” appears on most rows, outnumbering explicitly labeled stages like Seed, Series A, and Series B (e.g., Spark Cleantech is labeled Series A at $35M on 2025-12-04, while Electra is “Series Unknown” at $333M on 2025-07-24). Several rows are “undisclosed” rather than “Series Unknown,” including HysetCo (undisclosed on 2026-04-22) and Tiamat (undisclosed on 2024-01-15), meaning a portion of the list cannot be compared by amount.
Where do the biggest disclosed rounds sit relative to each other: are there multiple “upper tier” financings or one clear peak?
There is a clear peak at Neoen’s $885M (2024-12-18), but the next tier is still substantial rather than uniform: Waga Energy’s $180M (2025-11-27) and Electra’s $333M (2025-07-24) form a noticeable upper band. Below that, several rounds land in the tens of millions (e.g., Spark Cleantech $35M on 2025-12-04 and NewHeat $33M on 2023-11-21), creating a steep drop from the high hundreds.
