Frequently asked
What stands out on deal size for these Series C biotechnology rounds, and is it driven by a single outlier?
The largest disclosed amount is NewLimit’s $435M on 2026-06-02, which is far above the rest of the disclosed set, including Tubulis at $358M (2025-10-19) and Kriya Therapeutics at $313M (2025-08-15). Many other disclosed rounds sit below $200M, making NewLimit the dominant size outlier in this table.
Do the most recent rounds cluster by time, or are they spread evenly across the period shown?
There is a dense run in June 2026: four Series C rounds (Flare Therapeutics $85M on 2026-06-30; Triveni Bio $65M on 2026-06-17; CereVasc $85M on 2026-06-04; NewLimit $435M on 2026-06-02). That contrasts with earlier dates in the list, with the oldest shown being Scorpion Therapeutics at $150M on 2024-07-16.
Is any location over-represented across these rounds?
The Massachusetts cluster is noticeable, especially around Cambridge/Boston. Cambridge-based entries include Flare Therapeutics ($85M, 2026-06-30), Storm Therapeutics ($56M, 2026-04-16), and Cognito Therapeutics ($105M, 2026-03-05), with nearby Boston-based Elektrofi ($112M, 2024-08-27) and Boston/Cambridge-adjacent listings like CereVasc (Auburndale, $85M on 2026-06-04).
How often do disclosed amounts go missing in this set, and which companies are affected?
Two of the 50 rows use undisclosed amounts: Click Therapeutics on 2025-03-19 and Cortechs.ai on 2024-11-20. All other entries in this slice provide explicit dollar amounts, which enables the size outlier comparison (NewLimit’s $435M vs. the rest of the disclosed rounds).
Where do most rounds fall on the disclosed-dollar range, relative to the largest and the mid-tier?
While the top disclosed round is $435M (NewLimit, 2026-06-02), several other large raises cluster in the $300M–$360M band, including Tubulis ($358M, 2025-10-19) and Kriya Therapeutics ($313M, 2025-08-15), plus ArsenalBio at $325M (2024-09-04). Below that, numerous entries sit in the $100M–$200M band (e.g., Aspen Neuroscience $115M on 2025-11-20 and Alpha9 Theranostics $175M on 2024-10-23), indicating a broader mid-tier concentration rather than a smooth gradient.
Are there any notable small-ticket disclosed rounds that differ sharply from the rest of the distribution?
On the low end of disclosed amounts, ENYO Pharma is listed at $7M (2025-06-12) and Nuclera at $12M (2026-01-13), both well below the mid-tier examples like Lumen Bioscience at $30M (2025-10-08) and many $50M–$100M rounds. These smaller disclosed entries form a clear lower tail relative to the dominant $200M+ raises.
