How this list is built

DryPowder lists every fund with a public profile tagged Pre-Seed and Biotech and headquartered in San Francisco. Funds whose largest published check is $5M or less come first; inside each group, funds with a verified SEC Form D in the last 30 days lead, then profile quality decides. Form D dates come from SEC EDGAR, and SPV and single-deal filings are dropped. Check sizes are what each fund publishes; the median uses only the 2 funds that publish one.
