Los Altos-based AI funding in this list spans from 2020-04-28 (HeartVista.ai, $9M) to 2026-06-24 (xCures, $46M). The largest disclosed round is Alto Neuroscience’s $120M on 2026-03-16, which is a clear outlier above the rest of the disclosed amounts (the next-highest disclosed entries are in the $80M–$56M range: VERSATILE $80M on 2021-09-14 and Astrocade AI $56M on 2026-05-05).
A second pattern is the stage and disclosure mix: 5 of 22 rows are “undisclosed” ($2M is disclosed for Huma.AI, but several others are not), and 7 of 22 are “Series Unknown,” including Alto Neuroscience (2026-03-16, $120M) and Prezent AI (2026-04-30, undisclosed). Temporally, funding clusters around late 2025 to mid-2026, with multiple rounds between 2026-03-16 (Alto Neuroscience, $120M) and 2026-06-24 (xCures, $46M).

Frequently asked
What’s the largest disclosed round here, and how does it compare to the rest of the disclosed amounts?
Alto Neuroscience’s $120M on 2026-03-16 is the largest disclosed amount. It sits well above the next-largest disclosed figures: VERSATILE’s $80M (2021-09-14) and Astrocade AI’s $56M (2026-05-05).
How much of this Los Altos AI activity falls into the most recent window on the page?
The newest 90-day window contains entries including Astrocade AI ($56M on 2026-05-05), xCures ($46M on 2026-06-24), and Prezent AI (2026-04-30, undisclosed). More broadly, there’s a tight run from 2026-03-16 (Alto Neuroscience, $120M) through 2026-06-24 (xCures, $46M).
Is there a disclosure or “stage unknown” pattern that affects how to interpret comparisons?
Yes: 5 of 22 rows show “undisclosed” amounts (e.g., Prezent AI on 2026-04-30 and Spot AI on 2025-12-17), and 7 of 22 rows label the round as “Series Unknown” (including Alto Neuroscience with $120M on 2026-03-16). That means disclosed comparisons cluster around a subset of rows rather than every stage category.
Which stage labels dominate among disclosed rounds, and where do they differ?
Among clearly labeled stages with disclosed dollar amounts, Series B appears frequently, including Astrocade AI ($56M, 2026-05-05), Deep Vision ($35M, 2021-09-14), VERSATILE ($80M, 2021-09-14), and Otter.ai ($50M, 2021-02-25). Seed/debt-style rounds also exist but look smaller on disclosed figures, such as Napkin AI’s $10M (2024-08-07) and Avaamo’s $7M debt financing (2021-08-02).
Are there any notable outliers besides the top disclosed round?
Besides Alto Neuroscience’s $120M (2026-03-16), there’s a low-end disclosed floor at $1M for Bryte on 2024-08-08, which is far below most other disclosed rounds like Placer.ai’s $27M (2022-07-01) and Brisk Teaching’s $15M (2025-03-26). The highest disclosed cluster also includes $80M (VERSATILE, 2021-09-14) and $60M (Semiotic AI, 2021-12-09), suggesting a wider spread between mid-$teens and eight-figure rounds.
