Among the 43 listed San Carlos rounds (sorted by round date descending), the largest disclosed amount is Attovia Therapeutics’ $90M Series C on 2025-04-15. That figure dwarfs the rest: only Telo Trucks at $20M (2025-09-27) and Aetherflux at $50M (2025-04-02) reach above $20M disclosed, while most other disclosed rounds sit well below $20M (for example Clear Labs at $30M on 2025-01-13; XP Health at $33M on 2024-09-12; Galvanize Therapeutics at $100M is larger but appears at $100M in 2022-09-15—still not above $100M listed here, so the top disclosed remains $90M among these rows). The timing concentrates heavily in 2024–2025, with multiple multi-million rounds clustered across early 2024 (e.g., Elegen $35M on 2024-05-14; Swift Solar $7M on 2024-05-16; Q Bio $27M on 2024-07-18). Sector-wise, biotechnology is the most frequent category shown across rows (appearing in repeated entries such as Attovia Therapeutics 2025-04-15, Onc.AI 2024-10-24, CuraSen Therapeutics 2024-09-18, and many others), while “undisclosed” and “Series Unknown” appear often enough to blur stage comparisons (undisclosed amounts include equal1 2025-02-07, Swivl 2025-01-29, and Ebb Carbon 2023-10-18). The newest round shown is Telo Trucks on 2025-09-27, and the oldest is Nautilus Biotechnology on 2020-05-21.

Frequently asked
What stands out as the largest disclosed round in San Carlos, and how far ahead is it versus other disclosed amounts?
Attovia Therapeutics’ $90M Series C on 2025-04-15 is the largest disclosed amount in the list. The next highest disclosed amounts shown include $50M for Aetherflux (2025-04-02) and $33M for XP Health (2024-09-12), so the $90M entry is materially ahead of the rest of the disclosed amounts.
Do the rounds cluster in a particular date window, or are they evenly spread across years?
They cluster in the most recent years shown: the newest entry is Telo Trucks on 2025-09-27, and the oldest is Nautilus Biotechnology on 2020-05-21, but many of the higher-activity months sit in 2024 and early 2025. Examples include multiple 2025 rounds in Q1 (Clear Labs $30M on 2025-01-13; Qualified Health $30M on 2025-01-08; Aetherflux $50M on 2025-04-02) rather than a uniform spread.
Which sectors appear most often, and does any sector pair with higher-dollar rounds?
Biotechnology is the most repeatedly listed sector across the rows (e.g., Attovia Therapeutics $90M on 2025-04-15; Onc.AI $2M on 2024-10-24; CuraSen Therapeutics $6M on 2024-09-18; Imago BioSciences $80M on 2020-11-19). Larger disclosed rounds in the list also frequently align with biotech or adjacent healthcare/health categories, such as Galvanize Therapeutics at $100M on 2022-09-15 and Eiger BioPharmaceuticals at $75M on 2022-06-07.
How much does missing stage information affect analysis of stage mix here?
Stage is frequently not specified: several rows list “Series Unknown” (e.g., equal1 on 2025-02-07; Swivl on 2025-01-29; Onc.AI on 2024-10-24; Q Bio on 2024-07-18), and some entries also carry “undisclosed” amounts (equal1 $undisclosed, Swivl $undisclosed, Ebb Carbon $undisclosed on 2023-10-18). This makes it harder to compare disclosed-size outcomes by stage classification.
Are there outliers beyond the largest round, such as unusually small disclosed amounts or unusual support types?
Yes: among disclosed amounts, Greyscale AI shows a very small disclosed round at $500K on 2023-09-12, which is far below most other multi-million figures (for instance, Sensigo $5M on 2023-10-05 and CellFE $22M on 2023-09-27). There are also non-standard deal structures in the mix, such as CRISP-HR Therapeutics receiving Non-equity Assistance on 2022-03-16 ($100K) and Natera listing Post-IPO Equity on 2022-03-16 ($5M), which behave differently from typical equity round patterns.
Which entries fall closest to the present (using round dates), and do they show a consistent funding magnitude?
In the most recent cluster of dates, Telo Trucks closed 2025-09-27 at $20M, while several 2025 early entries are much larger or mid-sized, including Attovia Therapeutics at $90M (2025-04-15), Aetherflux at $50M (2025-04-02), and Clear Labs at $30M (2025-01-13). At the same time, multiple 2025 entries have undisclosed amounts (equal1 on 2025-02-07 and Swivl on 2025-01-29), so funding magnitudes in the latest period are not fully comparable.
