Funded Startups in Los Altos
Los Altos’ most recently disclosed rounds show a wide disclosed-amount spread.
Los Altos’ most recently disclosed rounds show a wide disclosed-amount spread. The largest disclosed amount in these 50 rows is AltruBio’s $225M Series B on 2024-05-21, which dwarfs the next-largest disclosed rounds visible here (for example Contrast Security’s $150M on 2021-11-09 and Glass Imaging’s $20M on 2025-05-12). At the same time, the list is anchored in a tight geographic label (all entries are tagged “Los Altos, California”) while sector concentration is notable: Artificial Intelligence (including AI-labeled entries like Descope on 2025-10-04 and Brisk Teaching on 2025-03-26) appears repeatedly across the timeline.
Timing clusters are clearer than sector taxonomy: the 2025 portion runs from 2025-02-04 (Archive) through 2025-10-04 (Descope), and multiple mid-2024 entries stack around 2024-05 (e.g., AltruBio $225M; Glass Imaging $20M is in May 2025, not 2024; while May 2024 includes AltruBio and Simr/ formerly UberCloud on 2024-05-21 with $20M). Several rounds also lack disclosed amounts or stage classification—11 entries are “undisclosed” on amounts or “Series Unknown” types are common—creating an uneven view of deal size beyond the disclosed outliers.

Frequently asked
Which disclosed rounds are the biggest outliers in Los Altos, and how far above the rest are they?
AltruBio’s $225M Series B on 2024-05-21 is the largest disclosed amount in the 50 rows and is far above the next-largest disclosed amounts shown, including Contrast Security’s $150M on 2021-11-09 and Avaamo’s $7M-level rounds elsewhere (e.g., Avaamo on 2021-08-02).
How concentrated are rounds by date in this Los Altos list?
The most recent round is Descope on 2025-10-04, while the oldest dated row shown is 2021-02-17 (vArmour). Beyond that, several entries cluster within the same month—2024-05-21 includes AltruBio ($225M) and Simr (formerly UberCloud) ($20M), both in Los Altos.
Are there sectors that dominate the Los Altos funding activity in this snapshot?
Artificial Intelligence appears repeatedly across the rows (e.g., Descope on 2025-10-04 for AI apps; Brisk Teaching on 2025-03-26 for AI; Auxia on 2025-03-04 for AI), while other categories are present but less consistently labeled in consecutive entries (such as Biotechnology with AltruBio on 2024-05-21 and RenovoRx on 2024-04-08).
What stage/label ambiguity affects deal-size comparisons here?
Some entries don’t provide comparable stage or amount details: at least one row shows an “undisclosed” amount (e.g., SecureThings on 2025-02-13), and “Series Unknown” appears multiple times (e.g., Prósperos on 2025-05-15 for $250K and GEODNET on 2025-02-26 for $8M), limiting how cleanly stage-size patterns can be inferred across the list.
Which entries provide the clearest high-to-mid range comparison on disclosed funding size?
Within the disclosed amounts, several mid-to-high rounds recur: Archive is $30M (2025-02-04), Spot AI is $31M (2024-10-31), and Placer.ai is $27M (2022-07-01). These are still small relative to the top disclosed outlier AltruBio at $225M (2024-05-21) and other large disclosed rounds like Contrast Security’s $150M (2021-11-09).
