Among the 48 San Carlos entries shown, the largest disclosed round is Cowboy Space’s $305M closed on 2026-05-11 (Series B). That figure dwarfs the next-largest disclosed amounts in the list—Farmers Business Network’s $300M (2021-11-18, Series G) and a $90M biotechnology round at Attovia Therapeutics (2025-04-15, Series C)—while most other disclosed rounds cluster far below $50M.
The most recent activity is tightly windowed: 2026 dates run from 2026-05-11 (Cowboy Space) through 2026-06-05 (BioCardia), with multiple rounds between April and May 2026 (e.g., Protuoso Biosciences $10M on 2026-05-27; Sapho Bio $5M on 2026-04-29; Ventaris Surgical $30M on 2026-01-09). Sector concentration is strongest in Biotechnology (11 entries), and disclosure is frequently incomplete: “undisclosed” appears in 5 rows (e.g., Novity 2026-05-20; equal1 2025-02-07; Swivl 2025-01-29), while “Series Unknown” appears in 10 rows (e.g., BioCardia 2026-06-05; Novity 2026-05-20; equal1 2025-02-07). The date range spans 2020-05-21 (Nautilus Biotechnology) through 2026-06-05 (BioCardia).

Frequently asked
What stands out as the largest disclosed round in San Carlos, and how different is it from the rest of the disclosed amounts?
Cowboy Space’s $305M (2026-05-11, Series B) is the largest disclosed amount in the list, with the next-largest disclosed amounts far closer to the high end but still well below it: Farmers Business Network’s $300M (2021-11-18, Series G) and Attovia Therapeutics’ $90M (2025-04-15, Series C).
Do these funding dates cluster in a narrow recent window, or are they evenly spread across years?
They cluster toward the most recent months: in 2026 alone, rounds run from 2026-01-09 (Ventaris Surgical, $30M) through 2026-06-05 (BioCardia, $4M), including multiple April–May entries such as Cowboy Space ($305M on 2026-05-11), Protuoso Biosciences ($10M on 2026-05-27), and Sapho Bio ($5M on 2026-04-29).
Which sectors are over-represented in this list of San Carlos-funded startups?
Biotechnology is the most concentrated sector, appearing 11 times across the 48 rows (e.g., BioCardia 2026-06-05 $4M; Attovia Therapeutics 2025-04-15 $90M; Imago BioSciences 2020-11-19 $80M). Other sectors show up fewer times, and Energy appears repeatedly but below Biotechnology’s count (e.g., Aetherflux $50M on 2025-04-02; Swift Solar $7M on 2024-05-16).
How much of the dataset has incomplete disclosure for round size or stage?
Round size is “undisclosed” in 5 rows (Novity 2026-05-20; equal1 2025-02-07; Swivl 2025-01-29; Ebb Carbon 2023-10-18; Flow Networks 2023-03-09). “Series Unknown” appears in 10 rows (including BioCardia 2026-06-05 $4M and Qualified Health 2025-01-08 $30M is labeled Seed, while several others like Novity 2026-05-20 are tagged “Series Unknown”).
Are there outliers that combine size extremes with a different stage classification?
CRISP-HR Therapeutics shows an unusually small disclosed amount of $100K (2022-03-16, Non-equity Assistance), versus multiple much larger equity-style rounds such as Galvanize Therapeutics $100M (2022-09-15, Series B) and WorkRamp $40M (2022-03-23, Series C). At the high end, Farmers Business Network’s $300M (2021-11-18, Series G) is also distinct from most other rounds, which largely stay under $50M in disclosed size.
What does the stage mix look like among the disclosed rounds (with special attention to dominant labels like Seed or Series A/B)?
Seed appears frequently alongside higher stages: for example, Sapho Bio is Seed at $5M (2026-04-29), Switch Bioworks is Seed at $17M (2024-09-05), and Sensigo is Seed at $5M (2023-10-05). Meanwhile, Series B and Series C are also prominent at larger dollars—for instance, Clear Labs is Series D at $30M (2025-01-13) while Attovia Therapeutics is Series C at $90M (2025-04-15) and XP Health is Series B at $33M (2024-09-12), indicating a skew toward disclosed mid-to-large rounds when later stage labels are present.
