Disclosed round sizes in Stamford skew heavily: the largest disclosed amount is Six One Commodities at $800M (2026-05-08), which dwarfs the next-largest disclosed entries such as Aircastle’s $375M (2026-05-21) and Treeline Biosciences’ $261M (2022-10-11). At the small end, the smallest disclosed amount is The Corebev Group at $100K (2021-12-20), and most other disclosed rounds cluster far above that floor (e.g., Keep America Beautiful at $250K on 2026-04-24; ApiJect at $430K on 2024-10-24). The 50 most recent rows span 2021-08-23 (Shelf) through 2026-06-11 (Sands Point Risk).
Multiple clusters show up in both time and classification. Rounds concentrate in the mid-2026 window: on/around May 2026, several disclosed amounts appear (e.g., Six One Commodities $800M on 2026-05-08; OncoSynergy $7M on 2026-05-26; Aircastle $375M on 2026-05-21). By stage labeling, “Series Unknown” dominates the list at 22 of 50 rows, with an additional 6 rows marked “undisclosed” on amount. Sector-wise, Financial Services and Biotechnology each appear in 3+ entries (Financial Services includes Aircastle, Bennie, Tomo, Adroit Trading Technologies, Nest Collaborative, etc.; Biotechnology includes OncoSynergy, Treeline Biosciences, SpringWorks Therapeutics). Geography is overwhelmingly Stamford, with one same-name “Stamford” outside the US: Eleanor in Stamford, Lincolnshire, United Kingdom (seed, 2021-10-01, $100K).

Frequently asked
Which disclosed round is the clear outlier in Stamford, and what sits next to it?
Six One Commodities’ $800M (Series Unknown) closed on 2026-05-08 and is an outlier versus the rest; the next-largest disclosed amounts are Aircastle at $375M (2026-05-21) and Treeline Biosciences at $261M (2022-10-11). The comparison is driven only by disclosed amounts, where several other entries fall into much smaller bands such as $10M–$50M (e.g., Throne SPORT COFFEE $10M on 2026-02-19; SponsorUnited $35M on 2022-11-21).
How much of the activity is concentrated near the most recent months in this list?
A tight recent cluster appears in May–June 2026: disclosed rounds include Six One Commodities $800M (2026-05-08), Aircastle $375M (2026-05-21), OncoSynergy $7M (2026-05-26), and Altus Power and Sands Point Risk with undisclosed amounts (2026-06-02 and 2026-06-11). The most recent dated entry is Sands Point Risk on 2026-06-11, while the oldest shown is Shelf on 2021-08-23.
What stage/amount disclosure patterns show up repeatedly across these 50 rows?
“Series Unknown” appears in 22 of 50 rows, and “undisclosed” amounts appear in 7 of 50 rows (e.g., Sands Point Risk 2026-06-11; Altus Power 2026-06-02; Digital Currency Group 2021-11-18 $600M is disclosed, but Keter Environmental Services 2021-11-02 is undisclosed). This creates an analyst tradeoff: many rounds are timestamped but require extra diligence on both stage and economics.
Are any sectors over-represented relative to the rest of the Stamford entries?
Financial Services and Biotechnology each show up at least 3 times: Financial Services includes Aircastle ($375M on 2026-05-21), Bennie ($50M on 2025-12-08), Tomo ($20M on 2025-03-11 and $40M on 2022-03-21), and Adroit Trading Technologies ($15M on 2024-02-06). Biotechnology includes OncoSynergy $7M (2026-05-26), Treeline Biosciences $261M (2022-10-11), and SpringWorks Therapeutics $225M (2022-09-07).
Which geography looks like the main outlier within the Stamford-named set?
All rows are Stamford (United States) except one: Eleanor is listed as Stamford, Lincolnshire, United Kingdom, with a seed round on 2021-10-01 for $100K. For US-based Stamford entries, the disclosed amounts include large outliers like Six One Commodities’ $800M (2026-05-08) and comparatively small checks like The Corebev Group’s $100K (2021-12-20, Stamford, United States).
