Among the 50 most recent disclosed rounds for Somerville-based startups, the largest disclosed amount is Form Energy’s $450M round on 2022-10-04. That figure dwarfs the rest of the disclosed set: the next-largest disclosed rounds nearby include BrainCo’s $286M (2026-01-06) and Sunwealth Power’s $290M (2024-11-25), while many other listed amounts cluster in the low-to-mid tens of millions (for example, VIA at $28M on 2025-03-18; Alloy Enterprises at $26M on 2023-05-17).
The list also shows concentration in two ways: date-wise, multiple rounds land repeatedly in the 2025–2026 window (e.g., AgZen $10M on 2026-03-13 through Rise Robotics $17M on 2026-01-21, with additional funding through late 2025), and sector-wise, Energy and Biotechnology both recur at least 3 times (Energy examples include AgZen, SparkCharge, and Form Energy; Biotechnology examples include BrainCo, JURA Bio, and Windgap Medical). The geographic field is consistently “Somerville” (including one “Somerville, United States” entry), while stage labels are frequently missing: 9 entries are marked “undisclosed” and 15 are “Series Unknown,” spanning the temporal edges from 2021-11-22 (Teal Bio) to 2026-03-13 (AgZen).

Frequently asked
What’s the largest disclosed round in this Somerville list, and how extreme is it versus other disclosed amounts?
Form Energy’s $450M round on 2022-10-04 is the clear outlier, sitting far above the rest of the disclosed set. The next-largest disclosed entries shown are in the hundreds of millions as well, including Sunwealth Power’s $290M (2024-11-25) and BrainCo’s $286M (2026-01-06), while many other disclosed rounds are in the teens to 30s (for example, VIA $28M on 2025-03-18; Alloy Enterprises $26M on 2023-05-17).
Do any funding amounts in the list fall unusually low compared with the rest?
The smallest disclosed amount is Forge’s $30K on 2024-09-17. Most other disclosed rounds are materially higher—for instance, Novaurum Biosciences at $310K (2025-03-11) and Cascade Climate at $500K (2023-12-20), with several entries in the $1M–$5M range such as Greentown Labs $4M (2024-12-18) and Singularity Energy $5M (2022-05-24).
How concentrated are rounds in the most recent part of the timeline?
The recency edge runs from 2021-11-22 (Teal Bio, $3M) up to 2026-03-13 (AgZen, $10M), and there is heavy clustering in 2025–2026. Examples include BrainCo on 2026-01-06 for $286M, Rise Robotics on 2026-01-21 for $17M, and multiple mid-to-late 2025 rounds such as SparkCharge $16M (2025-05-20) and VIA $28M (2025-03-18).
Are specific sectors over-represented among Somerville-based funded startups here?
Energy and Biotechnology each recur across multiple entries in the table. Energy examples include Form Energy ($450M on 2022-10-04), Sunwealth Power ($290M on 2024-11-25), and SparkCharge ($16M on 2025-05-20), while Biotechnology examples include BrainCo ($286M on 2026-01-06), JURA Bio ($16M on 2023-09-21), and Windgap Medical ($39M on 2022-01-20).
Is stage classification commonly missing, and does that pattern affect comparability of “largest rounds” by stage?
Stage labels are frequently absent or not specified: 9 rows are “undisclosed” on amount and 15 rows are “Series Unknown.” That means the largest/distribution comparisons rely only on disclosed amounts, even though examples with missing amounts exist throughout (e.g., Tulip Interfaces is “undisclosed” on 2025-12-22; Matterworks is “undisclosed” on 2025-06-03; Eden is “undisclosed” on 2024-02-11).
