Nineteen Boston-area energy startups are shown across disclosed rounds ranging from $3M up to $118M, where BlueWave’s $118M round (2025-02-06) is a clear outlier: it sits well above the next-largest disclosed amounts of $75M (VEIR, 2025-01-28) and $32M (REsurety, 2024-10-15). Most disclosed rounds cluster in a middle band—$10M to $32M appears repeatedly (e.g., REsurety $32M; Perch Energy $30M on 2023-10-11; Gridwealth $30M on 2023-04-12; Acoustic Wells $10M on 2023-08-29), while several entries are undisclosed.
From a timing and stage perspective, the listing spans 2020-10-14 (SunDensity, $3M) through 2025-07-02 (Luminous, $3M), with two recent bursts: three disclosed rounds in the first half of 2025 (Luminous 2025-07-02 $3M; Vicinity Energy 2025-06-18 $2M; Cala Systems 2025-06-03 $5M) and multiple October 2024 closings (Elevate Renewable Energy 2024-10-18 $28M; REsurety 2024-10-15 $32M). Stage disclosure is also skewed: 13 of 19 entries are labeled “Series Unknown,” and another 3 of 19 are explicitly “undisclosed,” limiting comparisons when the highest-impact rounds are not fully detailed.

Frequently asked
Which disclosed round is the outlier in this Boston energy set, and how far ahead is it from the next-largest disclosed amount?
BlueWave’s $118M round on 2025-02-06 is the largest disclosed amount in the table and notably outstrips the next-largest disclosed rounds: VEIR at $75M (2025-01-28) and REsurety at $32M (2024-10-15).
Do the most recent rounds cluster into a narrow window, or are they evenly spread across the 2020–2025 span?
The time spread runs from 2020-10-14 (SunDensity, $3M) to 2025-07-02 (Luminous, $3M), but activity is not uniform. There’s a visible first-half-2025 cluster with three disclosed rounds on 2025-07-02 ($3M), 2025-06-18 ($2M), and 2025-06-03 ($5M), plus a second concentration in mid-October 2024 (Elevate Renewable Energy $28M on 2024-10-18 and REsurety $32M on 2024-10-15).
How much of the list is constrained by missing round information (Series Unknown vs undisclosed vs Seed/Series)?
Of 19 rows, 13 are labeled “Series Unknown” (e.g., Luminous 2025-07-02 $3M and BlueWave 2025-02-06 $118M), and 3 are explicitly “undisclosed” (Found Energy 2024-12-11; Swift Current Energy 2024-10-24; Emvolon 2024-10-08). That means only 3 entries are labeled with a more specific stage in the rows shown (including Seed, Series B, and Series C labels on specific dates).
Which stage labels show up among the disclosed rounds, and what share of the table do they represent?
Seed appears on three dated entries with disclosed amounts (Altus Thermal $3M on 2024-01-10; Mona Lee Solar $3M on 2023-09-21; Acoustic Wells $10M on 2023-08-29). Beyond Seed, Series B shows up on two disclosed rows (VEIR $75M on 2025-01-28; Perch Energy $30M on 2023-10-11), and Series C appears once (REsurety $32M on 2024-10-15).
Are there other notable size clusters besides the BlueWave outlier (for example, repeated mid-$20M to $30M rounds)?
Yes. A mid-to-upper range of disclosed rounds appears multiple times: Elevate Renewable Energy raised $28M (2024-10-18), REsurety raised $32M (2024-10-15), Perch Energy raised $30M (2023-10-11), and Gridwealth raised $30M (2023-04-12). These amounts sit far below BlueWave’s $118M but repeatedly above the $10M level (e.g., Acoustic Wells $10M on 2023-08-29).
