## Method and limits
- Source: 57 of the 58 rows carry an SEC filing (Form D or Form ADV). All 58 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 healthtech and digital health as a focus on its own site, or we observed it in the firm's portfolio. Place: head office in Massachusetts.
- 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), 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 (15) and completeness of the public record (10). Regional focus is our research, not an SEC figure. It is a measure of activity and fit, not of quality or returns.
- Fill rates: Of 58 rows: stage 44, sector 58, fund size 53, website 58. In the paid file: named decision-makers on 54 rows, firm email on 24, LinkedIn page on 31, check size on 2.
