Among the 50 most recent funded startups listed for South San Francisco, the largest disclosed round is Structure Therapeutics’ $547M on 2024-06-05, which dwarfs the rest of the disclosed amounts in this table (the next-largest disclosed amounts are $550M for Cytokinetics on 2024-05-22 and $550M is actually higher; in that case the top two are in the $547M–$550M range). Most funding entries cluster in the biotech and health stack: biotechnology appears in 30+ rows, and health/medical categories show up repeatedly across the same period.
Temporal concentration is visible near mid-2024: several major checks arrive within a few weeks (e.g., Cytokinetics $550M on 2024-05-22; Structure Therapeutics $547M on 2024-06-05; Sutro Biopharma $75M on 2024-04-02). There are also disclosure outliers: Stafl Systems (2024-06-27) and GigaMune (2023-03-13) are marked undisclosed, while the smallest disclosed amount is $1M (Senti Biosciences on 2025-05-22 and Titan Pharmaceuticals on 2025-04-11). Rounds span from 2022-11-17 (Sonomotion) through 2025-11-18 (Onepot.ai), with 2025 making up a large share of the most recent entries.

Cytokinetics closed a disclosed $550M round on 2024-05-22, followed closely by Structure Therapeutics at $547M on 2024-06-05. Both checks are in a narrow high-$500M band that is far above the rest of the disclosed amounts shown, which mostly sit well below $200M (for example, $263M for IDEAYA Biosciences on 2024-07-09 and $325M for ArsenalBio on 2024-09-04).
Are there clear date clusters in the middle of the period shown?
Yes, mid-2024 contains multiple large events packed into weeks: Cytokinetics at $550M (2024-05-22), Structure Therapeutics at $547M (2024-06-05), and NGM Biopharmaceuticals at $122M (2024-07-17). The same window also includes other substantial rounds like ArsenalBio at $325M on 2024-09-04.
