Funded Artificial Intelligence Startups in Cambridge
Among the 50 most recent AI-funding entries for Cambridge (U.S.
Among the 50 most recent AI-funding entries for Cambridge (U.S. and U.K. combined), the largest disclosed round is Suno’s $400M on 2026-06-03, which dwarfs the next-largest disclosed amounts (OpenEvidence $250M on 2026-01-21; Iterative Health $77M on 2026-04-30; Lila Sciences $115M on 2025-10-18). The list is also clustered by time: 2026 dominates, with multiple late-spring 2026 rounds on 2026-06-03 (Marble $30M, Suno $400M) and 2026-05-27 (Elemental Machines $6M), while the oldest row shown dates back to 2023-06-22 (BIOS; amount undisclosed). Geographically, entries concentrate in Cambridge, Massachusetts and Cambridge (Cambridgeshire) rather than being spread across many cities; however, Cambridge appears in both countries with the largest check (Suno) in Cambridge, Massachusetts and several large U.K. checks such as Luminance’s $75M on 2025-02-18. Stage and disclosure skew toward ambiguity and later rounds: 13 of 50 rows are “Series Unknown” and 4 of 50 are explicitly “undisclosed,” alongside a clear presence of Seed/Pre-Seed and multiple large late-stage rounds (e.g., OpenEvidence Series D $250M on 2026-01-21; Iterative Health Series C $77M on 2026-04-30).

Frequently asked
What stands out in round size, and how extreme is the top check versus the rest?
Suno’s $400M on 2026-06-03 is the only disclosed round above $250M, and it sits far above the next-largest disclosed amounts such as OpenEvidence’s $250M on 2026-01-21 and Lila Sciences’ $115M on 2025-10-18.
Do the most recent rounds cluster into specific windows rather than spreading evenly?
Yes. 2026 accounts for the newest entries (latest date 2026-06-11 for Shuimu BioSciences, undisclosed), with notable same-day clustering on 2026-06-03 (Marble $30M and Suno $400M) and additional late-May activity like Elemental Machines on 2026-05-27 ($6M).
Which geography dominates within “Cambridge,” and are the largest rounds tied to one side of the Atlantic?
Cambridge, Massachusetts appears repeatedly with major checks including Suno ($400M, 2026-06-03) and OpenEvidence ($250M, 2026-01-21). Cambridge (Cambridgeshire) also shows high amounts such as Luminance ($75M, 2025-02-18), but the single largest disclosed round belongs to Cambridge, Massachusetts.
How much of the list is unclear on deal size or classification?
Disclosure is mixed: 13 of 50 rows label the round as “Series Unknown,” and 4 of 50 rows show “undisclosed” amounts (e.g., Shuimu BioSciences on 2026-06-11; Techspert on 2026-02-11). That ambiguity matters when comparing top-end checks because only disclosed amounts can anchor “largest/smallest” comparisons.
Are there notable low-end outliers among disclosed rounds?
Among disclosed amounts, the smallest is $950K for Monumo on 2025-08-07; several other sub-$1M or near-$1M entries also appear (e.g., Tactful $1M on 2026-02-09 and Gander Robotics $1M on 2026-04-02), making the $400M Suno round an outlier by scale.
