Among the 50 pre-seed energy rounds shown, the largest disclosed amount is Cloover’s $7M on 2023-10-18; most other disclosed rounds cluster at $2M, with several $1M–$1.5M entries, while only a few sit above $3M (e.g., HyperHeat at $3M on 2024-11-26; 8links at $3M on 2024-05-13; EPYR at $3M on 2025-02-03; Active Surfaces at $6M on 2024-05-13). The smallest disclosed amount is Curio’s $100K on 2023-08-25, establishing a wide disclosed-range outlier versus the dominant $2M band.
Timing and geography form noticeable clusters: $2M rounds recur frequently across Europe (e.g., Tether $2M on 2025-06-19 in Stockholm; Zendo Energy $2M on 2025-05-12 in London; Orus Energy $2M on 2024-07-05 in Paris; Nomos $2M on 2024-10-15 in Berlin) and the most recent window (2025-03-12 through 2025-09-28) concentrates multiple $2M deals (Currentt $2M on 2025-07-03; Zendo Energy $2M on 2025-05-12; Tether $2M on 2025-06-19). Undisclosed amounts appear 13 times, and all rows are labeled Pre-Seed; round dates span 2023-06-01 (BlueBird Power) to 2025-09-28 (Wankel Energy Systems).

Frequently asked
What are the biggest and smallest disclosed rounds in this pre-seed energy list, and how extreme is the gap?
Cloover raised $7M (2023-10-18), which is well above the common $2M cluster and next-largest higher rounds like Active Surfaces at $6M (2024-05-13). At the low end, Curio’s disclosed $100K (2023-08-25) sits far below the $500K–$1M band seen in multiple entries.
Do disclosed amounts concentrate around a particular range (or do outliers dominate)?
A large share of disclosed rounds land at $2M (e.g., Currentt $2M on 2025-07-03; Tether $2M on 2025-06-19; Zendo Energy $2M on 2025-05-12; Orus Energy $2M on 2024-07-05; Nomos $2M on 2024-10-15). Outliers are comparatively fewer, such as Active Surfaces at $6M (2024-05-13) and HyperHeat at $3M (2024-11-26).
Which entries fall into the most recent date window shown, and is that window heavy on $2M rounds?
The list’s newest round is Wankel Energy Systems at $1M on 2025-09-28. Within the latest stretch from 2025-06-11 to 2025-09-28, multiple disclosed rounds are $2M (e.g., Tether $2M on 2025-06-19; Zendo Energy $2M on 2025-05-12 is just outside, but Currentt $2M on 2025-07-03 is inside), alongside smaller disclosed entries like Voltavate $550K on 2025-06-11.
Are there geographic hubs or repeated city patterns across these rounds?
Europe shows repeated $2M placements across different cities—Stockholm (Tether $2M on 2025-06-19; Cloover $7M on 2023-10-18), London (Zendo Energy $2M on 2025-05-12; RYE is undisclosed on 2024-09-01), Paris (EPYR $3M on 2025-02-03; NetZero is undisclosed on 2023-06-15; Orus Energy $2M on 2024-07-05). Several UK/EU capitals appear multiple times, suggesting clustering by major cities rather than a single single-city hotspot.
How prevalent are undisclosed amounts, and does that affect identifying the top/bottom disclosed rounds?
Undisclosed amounts appear 13 times in the 50 rows (for example, ChargeNet on 2025-05-19 and SunTrain on 2025-03-17). Because largest/smallest comparisons rely on disclosed amounts, the top disclosed anchor remains Cloover’s $7M (2023-10-18) and the smallest disclosed anchor remains Curio’s $100K (2023-08-25).
Is the sector mix consistent here, or are there any stage/sector discrepancies within the table?
Every row shown is labeled Energy and the stage is uniformly Pre-Seed, so there is no stage mix variation to explain the spread. The main diversification signal is in disclosed funding size (e.g., Active Surfaces $6M on 2024-05-13 versus Curio $100K on 2023-08-25) rather than in sector or stage labels.
