Among the six Brookline-based funded startups shown, the largest disclosed round is Liquid AI’s $250M (2024-12-13), which dwarfs the next-largest disclosed amount: Panoptic’s $7M (2023-11-20). Two rounds also sit far below the rest—SOND’s $150K (2026-05-28) and Navigation Sciences, Inc.’s $3M (2023-09-14)—creating a steep disclosed-amount spread.
The list clusters temporally around late 2023 to early 2025: Liquid AI (2024-12-13), Layer Health (2025-03-27), and Panoptic (2023-11-20) anchor the middle of the window, while the earliest shown round is Navigation Sciences, Inc. on 2023-09-14 and the most recent is SOND on 2026-05-28. Sector coverage is split across Consumer Electronics (SOND), Biotechnology (Oncoheroes Biosciences), AI (Layer Health, Liquid AI), Financial Services (Panoptic), and Health Care (Navigation Sciences, Inc.); AI appears in 2 of 6 entries. Stage labels are also uneven: 3 of 6 entries are “Series Unknown,” and one entry is explicitly “undisclosed.”

Frequently asked
What’s the biggest disclosed round in Brookline here, and how concentrated is the rest of the disclosed amounts?
Liquid AI’s $250M on 2024-12-13 is the only disclosed round in the $200M range, while the next-largest disclosed amount is Panoptic’s $7M on 2023-11-20. The disclosed floor is SOND’s $150K on 2026-05-28, with Navigation Sciences, Inc. at $3M on 2023-09-14.
Do these rounds cluster in a specific time window, or are they evenly spread across the date range shown?
They cluster around late 2023 through early 2025: Panoptic’s $7M closes on 2023-11-20, Liquid AI’s $250M closes on 2024-12-13, and Layer Health’s $21M closes on 2025-03-27. The range spans 2023-09-14 (Navigation Sciences, Inc.) through 2026-05-28 (SOND), with three entries concentrated between 2023-11-20 and 2025-03-27.
Which industries appear most, and is the concentration driven by a single sector?
AI is the only sector repeated in this set, appearing in 2 of 6 entries (Layer Health at $21M on 2025-03-27; Liquid AI at $250M on 2024-12-13). The other four entries are singletons across Consumer Electronics (SOND), Biotechnology (Oncoheroes Biosciences), Financial Services (Panoptic), and Health Care (Navigation Sciences, Inc.).
What does the stage/label mix look like, and how much of the set lacks disclosed classification or funding size?
Stage labels are fragmented: 3 of 6 entries are “Series Unknown” (SOND on 2026-05-28; Oncoheroes Biosciences on 2026-01-12; Liquid AI’s row is a named Series A, so not part of this count), while Oncoheroes Biosciences is also “undisclosed” on the amount field. Only Layer Health (Series A, $21M on 2025-03-27), Liquid AI (Series A, $250M on 2024-12-13), Panoptic (Seed, $7M on 2023-11-20), and Navigation Sciences, Inc. (Series B, $3M on 2023-09-14) have explicit stage labels.
Are there outliers worth attention beyond just the largest check size?
Yes. The $250M Liquid AI round on 2024-12-13 is the clear high outlier, but there’s also a low outlier on the other end: SOND’s $150K on 2026-05-28 sits far below the next-lowest disclosed amount of $3M (Navigation Sciences, Inc. on 2023-09-14). Oncoheroes Biosciences on 2026-01-12 is an additional outlier in disclosure style because its amount is “undisclosed.”
