Seed-stage biotechnology rounds in this list show a clear split between a single top tier and a broader lower-disclosed range: TRIMTECH Therapeutics raised $14M on 2026-06-23, which dwarfs the next-largest disclosed rounds clustered at $13M (ParcelBio, 2026-05-07) and $10M (Protuoso Biosciences, 2026-05-27). The largest disclosed amount sits well above the rest of the disclosed entries, where multiple rounds land in the high-single-digits, including $9M rounds for Kopra Bio (2026-06-16), Portal (2026-06-18), and Psilera Bioscience (2026-05-28).
Geographically, the table is anchored by repeat hubs: San Francisco appears 5 times, alongside Boston (2) and San Carlos (2), suggesting recurring local networks rather than a one-off cluster. Temporally, rounds span 2026-04-22 to 2026-07-15, with several of the biggest disclosed closings occurring in May to late June (for example, ParcelBio on 2026-05-07 and TRIMTECH Therapeutics on 2026-06-23). Of the 50 rows shown, 36 disclose amounts while 14 are undisclosed.

Frequently asked
Which seed round is the outlier by disclosed size, and how far above the rest does it sit?
TRIMTECH Therapeutics’ $14M seed round (2026-06-23) is the largest disclosed amount shown and sits above the next-largest $13M ParcelBio round (2026-05-07). After that, the high-single-digit cluster (e.g., $10M Protuoso Biosciences on 2026-05-27 and $9M rounds such as Kopra Bio on 2026-06-16) is where most of the disclosed amounts concentrate.
Are there specific cities that repeat frequently across these seed-funded biotech companies?
San Francisco appears 5 times in the list, compared with Boston at 2 and San Carlos at 2, indicating a disproportionate concentration in the Bay Area over a purely dispersed set of geographies. Examples include Kopra Bio (San Francisco, 2026-06-16) and Protuoso Biosciences (San Carlos, 2026-05-27).
What proportion of rows have disclosed amounts versus undisclosed seed rounds?
