Top 5 seed biotech investors, ranked by recent fund activity
Among firms with a published profile and a dated fund or deal in the last 24 months. The rule: Activity score out of 100: recency of the latest fund filing or dated deal (35: full marks within 3 months, then stepping down at 6, 12 and 24 months), share of the observed portfolio in this sector (25; half of that when the sector is stated only), stage focus (15: all of it when seed is the only stage the firm states, split evenly when it states more), size of the fund on file on a log scale (15) and completeness of the public record (10). Stage focus is our research, not an SEC figure. It is a measure of activity and fit, not of quality or returns. The same rule orders the whole list; it is repeated in the method box.

- Inclusion rule
- Organizations that back startups. Individuals, buyout funds and firms we found to be inactive are left out. Sector: the firm states biotech and life sciences as a focus on its own site, or we observed it in the firm's portfolio. Stage: the firm states that it invests at seed.
- Order
- Firms with a published profile come first. Activity score out of 100: recency of the latest fund filing or dated deal (35: full marks within 3 months, then stepping down at 6, 12 and 24 months), share of the observed portfolio in this sector (25; half of that when the sector is stated only), stage focus (15: all of it when seed is the only stage the firm states, split evenly when it states more), size of the fund on file on a log scale (15) and completeness of the public record (10). Stage focus is our research, not an SEC figure. It is a measure of activity and fit, not of quality or returns.
