Frequently asked
Which disclosed round stands out in size, and how does it compare with the rest of the disclosed amounts?
Sortera Bio raised the largest disclosed pre-seed amount at $10M on 2025-06-05; the next-largest disclosed amounts are $7M (Level Zero Health, 2025-02-18) and $4M (Sift Biosciences on 2025-12-19; OutPost Bio on 2026-03-02). At the other extreme, ClearSight Therapeutics’ disclosed amount is $30K on 2024-09-06.
Do the disclosed rounds cluster in a narrow date window rather than spreading evenly across the full range?
The listing spans 2024-07-25 (oldest) to 2026-07-14 (most recent), but multiple of the largest disclosed rounds arrive in separate spikes rather than forming a single contiguous cluster. For example, $4M rounds appear on 2025-12-19 (Sift Biosciences) and 2026-03-02 (OutPost Bio), while the $3M tier includes Graph Therapeutics on 2025-01-09 and Lyora Therapeutics on 2026-07-14.
Are any locations over-represented among these pre-seed biotech entries?
London is the most frequent city, appearing five times across the rows (e.g., Voxmind on 2026-05-26 and Level Zero Health on 2025-02-18), while Basel appears twice (e.g., ClearideBio Therapeutics on 2026-06-11 with undisclosed amount and the Basel-associated listings in 2025). Other cities generally appear once within the shown set.
What fraction of entries have disclosed funding amounts, and does undisclosed data materially affect interpreting “largest” and “smallest”?
Of 50 rows, 33 have disclosed amounts and 17 are undisclosed, so rankings like “largest disclosed” and the smallest disclosed value rely on that disclosed subset. The largest disclosed amount is Sortera Bio’s $10M (2025-06-05), while the smallest disclosed amount is ClearSight Therapeutics’ $30K (2024-09-06).
Which entries are worth immediate attention as large outliers within the disclosed subset?
Beyond the $10M Sortera Bio round (2025-06-05), the other high outliers in the disclosed ranking are $7M Level Zero Health (2025-02-18) and two $4M rounds: Sift Biosciences (2025-12-19) and OutPost Bio (2026-03-02). These sit noticeably above the $3M tier, which includes Graph Therapeutics ($3M, 2025-01-09) and Lyora Therapeutics ($3M, 2026-07-14).
