Disclosed round sizes in this Somerville energy list range from $1M to $450M, with one clear outlier: Form Energy’s $450M Series E on 2022-10-04, which dwarfs every other disclosed amount shown (the next-highest disclosed is Sunwealth Power’s $290M on 2024-11-25). The 13 rows also show a tight cluster around the 2025-05-20 mark, where two Energy rounds are dated the same day (SparkCharge’s $16M Series A and Sublime Systems as Series Unknown, amount undisclosed).
Most entries are in Energy throughout, and stage labels are mixed: five of 13 rows are marked “Series Unknown,” while undisclosed amounts appear on two additional rows (Sublime Systems on 2025-05-20 and Eden on 2024-02-11). Temporally, the set spans from 2020-10-21 (Heila Technologies, $3M) through the most recent rounds on 2025-05-20 (SparkCharge and Sublime Systems).

Frequently asked
What are the outliers in disclosed round size, and how do they compare to the rest of the list?
Form Energy’s $450M on 2022-10-04 is the dominant disclosed outlier; Sunwealth Power’s $290M on 2024-11-25 is the next-largest disclosed round, and the remaining disclosed amounts fall well below those two (e.g., SparkCharge $16M on 2025-05-20; Glimpse $10M on 2025-03-05).
Is there a concentration in the most recent dates for Somerville energy rounds?
Yes: two entries are dated the most recent day shown, 2025-05-20—SparkCharge ($16M, Series A) and Sublime Systems (Series Unknown, undisclosed). Beyond that, there’s continued density in 2025 (Glimpse on 2025-03-05 for $10M and Addis Energy on 2025-01-21 for $5M).
How often do the listings omit stage or disclose the round amount?
Stage information is missing or labeled broadly in 5 of 13 rows marked “Series Unknown” (e.g., Sublime Systems 2025-05-20; Addis Energy 2025-01-21; Greentown Labs 2024-12-18). Separately, two rows show “undisclosed” amounts—Sublime Systems (2025-05-20) and Eden (2024-02-11)—so comparisons of “largest” are restricted to disclosed amounts only.
Does any stage label dominate the set, or is it spread across multiple stages?
It’s spread rather than dominated: besides the two outliers with large Series labels (Form Energy’s Series E on 2022-10-04 for $450M and SparkCharge’s Series A on 2025-05-20 for $16M), the list includes Seeds (Raise Green at $1M on 2023-06-14; Singularity Energy at $5M on 2022-05-24), Pre-Seed (Mesodyne, amount undisclosed, 2021-11-10), and multiple “Series Unknown” entries (e.g., Sunwealth Power $290M on 2024-11-25).
Which entries fall near the start and end of the shown timeframe?
The oldest row shown is Heila Technologies on 2020-10-21 with $3M (stage blank). The newest date is 2025-05-20, again anchored by SparkCharge’s $16M Series A and Sublime Systems (Series Unknown, undisclosed), creating a wide span from 2020-10-21 to 2025-05-20 across the 13 rows.
