## Method and limits
- Source: All 36 rows carry an SEC filing (Form D or Form ADV). All 36 have a website we checked. Filing date and fund size are SEC data where a filing exists. Stage, sector and check size are our research.
- Inclusion rule: Organizations that back startups. Individuals, buyout funds and firms we found to be inactive are left out. Sector: the firm states medtech and medical devices as a focus on its own site, or we observed it in the firm's portfolio. Stage: the firm states that it invests at Series B.
- Order: Activity score out of 100: recency of the latest fund filing or dated deal (30: full marks within 3 months, then stepping down at 6, 12 and 24 months), share of the observed portfolio in this sector (20; half of that when the sector is stated only), stage focus (15: all of it when Series B is the only stage the firm states, split evenly when it states more), stated focus on the US (15: full marks when the firm names the US as where it invests, half when it says global), size of the fund on file on a log scale (12) and completeness of the public record (8). Stage and regional focus are our research, not an SEC figure. It is a measure of activity and fit, not of quality or returns.
- Fill rates: Of 36 rows: stage 36, sector 36, fund size 29, website 36. In the paid file: named decision-makers on 34 rows, firm email on 15, LinkedIn page on 23, check size on 4.
