## Method and limits
- Source: 18 of the 42 rows carry an SEC filing (Form D or Form ADV). All 42 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 marketplaces 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 A.
- Order: 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 Series A 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.
- Fill rates: Of 42 rows: stage 42, sector 42, fund size 34, website 42. In the paid file: named decision-makers on 39 rows, firm email on 19, LinkedIn page on 29, check size on 19.
