In the most recent 37 AI funding rounds listed for San Mateo, the disclosed high is Generalist AI’s $400M (Series B) on 2026-06-04, which dwarfs the next-largest disclosed amounts: Feedzai’s $75M (2025-10-02) and two $73–78M rounds (Mendaera $73M on 2024-09-26; yellow.ai $78M on 2021-08-04). After that top end, disclosed rounds cluster much lower, with several sub-$10M entries such as Numos ($4M, 2026-04-02) and PatternFast ($500K, 2025-05-22).
Timing also concentrates: within the latest ~6 months (from 2025-12-03 onward), multiple disclosed rounds appear, including Wisdom AI ($50M, 2025-11-15), Feedzai ($75M, 2025-10-02), and Aurasell ($30M, 2025-08-26). The list is heavily “Artificial Intelligence (AI)” across rows (all 37), but stage labeling is uneven: there are 3 “undisclosed” amounts (AtScale 2025-12-18, Moss 2025-12-03, Vouchery.io 2023-08-12) and 6 “Series Unknown” classifications (Superb AI 2026-05-13, AtScale 2025-12-18, Brain Technologies 2024-02-25, plus three others with amounts shown as disclosed).

Frequently asked
What stands out in round size in this San Mateo AI set, and how extreme is it?
Generalist AI’s $400M on 2026-06-04 (Series B) is the only disclosed round in the $100M+ range here and it dwarfs the next-largest disclosed amounts such as Feedzai’s $75M (2025-10-02) and Mendaera’s $73M (2024-09-26). The smallest disclosed amount is PatternFast’s $500K on 2025-05-22, which sits far below the cluster of mostly $5M–$30M rounds.
Do funding dates cluster near the most recent period, or are they evenly spread across years?
They cluster toward the recent end: from 2025-08-26 (Aurasell $30M) through 2026-06-04 (Generalist AI $400M), there are multiple disclosed rounds, including Numos ($4M, 2026-04-02), Wisdom AI ($50M, 2025-11-15), and Hammerspace ($100M, 2025-04-16). The earliest disclosed entry shown is Arrikto’s $10M on 2020-11-16, so the set spans roughly 2020-11 through 2026-06.
How common are missing disclosures for amount or stage labels in this listing?
Amount disclosure is incomplete in 3 rows marked “undisclosed”: AtScale (2025-12-18), Moss (2025-12-03), and Vouchery.io (2023-08-12). Stage labeling is also incomplete or ambiguous in 6 “Series Unknown” rows, including Superb AI (2026-05-13, $400K) and Brain Technologies (2024-02-25, $30M), which limits direct stage-mix comparisons.
Are there repeat high-ticket rounds at the $70M–$100M level, or is size mostly lower here?
High-ticket rounds do appear, but they’re sparse relative to the rest: Hammerspace is $100M (2025-04-16), Evisort is $100M (2022-05-11), Feedzai is $75M (2025-10-02), and Mendaera is $73M (2024-09-26). Outside that band, many disclosed amounts fall into lower single-digit to tens of millions, such as Cornerstone AI’s $5M (2024-10-31) and EvaBot’s $11M (2022-07-28).
Any notable outliers besides the top $400M round?
Yes. PatternFast’s $500K on 2025-05-22 is a clear low-end outlier versus other disclosed rounds like PLATMA’s $2M (2024-09-10) and Numos’ $4M (2026-04-02). On the upper side, beyond Generalist AI’s $400M, only a small set reaches $100M (Hammerspace $100M on 2025-04-16; Evisort $100M on 2022-05-11), with the next tier clustering around the $70M–$78M range.
