Across the 16 most recent Mill Valley entries, the largest disclosed round is Achieve Life Science’s $180M (2026-04-16), which dwarfs the next-largest disclosed amounts: Redwood Trust’s $125M (2026-05-19) and the remaining disclosed rounds that sit far lower (e.g., Ambient Photonics at $30M on 2023-09-05, OK Capsule at $8M on 2023-01-01). The list also shows a staging pattern: five of the 16 rounds (Vidisky $180K on 2026-03-06; Sonar $2M on 2025-02-24; Taharka $90K on 2025-02-19; The Free Spirits Company $350K on 2023-03-21; Kerogen Systems $30K on 2022-10-24) cluster in sub-$1M or near-floor disclosed sizes rather than the mid-$10M to $30M range.
Timing clusters are visible as well. The most recent dates span from 2020-04-15 (Yes Health, $6M) through 2026-05-19 (Redwood Trust, $125M), with several high-value rounds concentrated in 2026 (Achieve Life Science $180M on 2026-04-16; Redwood Trust $125M on 2026-05-19; Vidisky $180K on 2026-03-06; Earthshot Labs marked undisclosed on 2025-05-02). Sector-wise, Biotechnology appears repeatedly (Achieve Life Science; Earthshot Labs; OK Capsule; Kerogen Systems; Jyzen Labs; Vidisky), while five entries include “Series Unknown” and two specify “undisclosed,” creating material disclosure gaps alongside the otherwise consistent Mill Valley location.

Frequently asked
Which disclosed round is the standout in Mill Valley here, and how far above the rest does it sit?
Achieve Life Science’s $180M (2026-04-16) is the largest disclosed amount in the table and is followed by Redwood Trust’s $125M (2026-05-19). After those two, the disclosed amounts generally fall well below that level, with examples like Ambient Photonics at $30M (2023-09-05) and OK Capsule at $8M (2023-01-01).
Are the biggest rounds clustered in a specific time window within these 16 entries?
Yes. The two largest disclosed rounds are both in 2026—Achieve Life Science $180M (2026-04-16) and Redwood Trust $125M (2026-05-19). In the same “recent” window, other disclosed sizes vary sharply (e.g., Vidisky $180K on 2026-03-06), indicating the high-end is time-adjacent rather than spread evenly across the full 2020–2026 range.
How many entries have unclear funding amounts or stages, and does that affect outlier detection?
Two entries list “undisclosed” amounts (Earthshot Labs on 2025-05-02; True Botanicals with undisclosed on 2023-03-22), and five entries use “Series Unknown” classifications (Redwood Trust 2026-05-19; Achieve Life Science 2026-04-16; Earthshot Labs 2025-05-02; Taharka 2025-02-19; The Earth Genome 2023-12-20). Because those amounts are missing, comparisons and “largest/smallest” conclusions rely only on the remaining disclosed values.
Does any sector show up often enough to be considered over-represented in this Mill Valley list?
Biotechnology is the clearest cluster, appearing in Achieve Life Science (2026-04-16, $180M), Earthshot Labs (2025-05-02, undisclosed), OK Capsule (2023-01-01, $8M), Kerogen Systems (2022-10-24, $30K), Jyzen Labs (2022-08-08, $12M), and Vidisky (2026-03-06, $180K is labeled Hardware in the row, so the biotech set is those first five plus OK Capsule/Jyzen/Kerogen). Other sectors appear fewer times (e.g., Health Care: Sonar 2025-02-24 $2M; Yes Health 2020-04-15 $6M).
Which entries look like they could be practical ‘budget-size’ outliers versus the mid-to-large rounds?
The disclosed floors are very low compared with the $30M-to-$180M band. Examples include Kerogen Systems at $30K (2022-10-24) and Taharka at $90K (2025-02-19), alongside Vidisky at $180K (2026-03-06) and The Free Spirits Company at $350K (2023-03-21). These sit far below the disclosed $8M–$33M cluster (OK Capsule $8M on 2023-01-01; Basis Theory $33M on 2025-10-17; Ambient Photonics $30M on 2023-09-05).
