Across 46 funded entries for Stamford, the largest disclosed round is Aircastle’s $600M (2025-05-05), which dwarfs the next-largest disclosed amounts (e.g., Hildene at $493M on 2024-11-13 and Altus Power at $100M on 2024-01-02). The disclosed values also show a heavy tail of mid-to-large rounds: several $200M+ exits/late-stage moves appear, including SpringWorks Therapeutics’ $225M (2022-09-07), Sema4’s $200M (2022-01-18), and Treeline Biosciences’ $261M (2022-10-11).
Date-wise, the list spans 2020-11-02 (American Halal Company) through 2025-09-29 (Notable). There is a tight recent cluster in 2025 (notably Notable at $6M on 2025-09-29; Aircastle at $600M on 2025-05-05; and Kibu at $2M on 2025-04-01), while staging is split between identifiable rounds and many unquantified disclosures: “Series Unknown” appears 14 times and “undisclosed” amounts appear 6 times.

Frequently asked
Which Stamford deal is the disclosed outlier in size, and what does it imply about the rest of the list?
Aircastle’s $600M (Series Unknown) on 2025-05-05 is the largest disclosed amount in the 46-row set, and it sits far above other large disclosed rounds such as Hildene’s $493M (2024-11-13) and Treeline Biosciences’ $261M (2022-10-11). The $200M+ tier also appears, but none approach the Aircastle figure.
Do the most recent rounds concentrate in a short time window?
Yes, multiple rounds land in 2025: Notable’s $6M closes on 2025-09-29, Aircastle’s $600M on 2025-05-05, Kibu’s $2M on 2025-04-01, and Tomo’s $20M on 2025-03-11. The oldest row shown is 2020-11-02 (American Halal Company), indicating the list includes both recent and longer-running activity.
How much of the activity is hard to compare because of missing or non-specific amount/stage fields?
Stage comparability is limited by classification and disclosure gaps: “Series Unknown” appears 14 times (e.g., Aircastle 2025-05-05; Hildene 2024-11-13), and “undisclosed” amounts appear 6 times (e.g., Symmera 2024-08-21; IronYun 2024-07-01; Apollo Intelligence 2022-09-08). That means outlier and clustering observations rely mainly on the disclosed-amount subset.
Are any sectors over-represented among Stamford-funded entries here?
Artificial Intelligence (AI) shows up repeatedly across the list—Noteworthy AI ($6M, 2023-10-20), Upswing Health ($5M, 2022-05-02), Copyleaks Inc. ($6M, 2022-05-24), Sema4 (Post-IPO Equity, $200M on 2022-01-18), and IronYun (undisclosed, 2024-07-01). This creates a distinct AI cluster compared with singletons in many other categories.
Which stage label appears often enough to indicate a consistent funding pattern in this city?
Series A is a recurring identifiable stage (e.g., Notable is labeled Series A on 2025-09-29 with $6M; Adroit Trading Technologies is Series A on 2024-02-06 with $15M; SponsorUnited is Series A on 2022-11-21 with $35M; BluSapphire is Series A on 2022-10-27 with $9M). The presence of multiple Series A datapoints alongside several Post-IPO Equity entries (SpringWorks Therapeutics $225M on 2022-09-07; Sema4 $200M on 2022-01-18) suggests both early-to-growth and later-stage financing has anchored the set.
Are there geographic or naming anomalies that could distort “Stamford-only” analysis?
One row appears outside the expected geography: Eleanor is listed as “Stamford, Lincolnshire, United Kingdom” (Seed, $100K on 2021-10-01), while the rest are “Stamford, Connecticut, United States.” Also, Tomo appears twice with different round dates and amounts ($20M on 2025-03-11 labeled Series B, and $40M on 2022-03-21 labeled Series A), which can matter when analyzing repeats.
