## Method and limits
- Source: 318 of the 322 rows carry an SEC filing (Form D or Form ADV). 321 of the 322 have a website we checked; the other 1 rests on the filing or register entry alone. 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. This list holds VC firms, fund managers and corporate venture arms; accelerators and angel networks are in their own lists. Sector: the firm states deep tech as a focus on its own site, or we observed it in the firm's portfolio.
- 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 322 rows: stage 258, sector 322, fund size 279, website 321. In the paid file: named decision-makers on 304 rows, firm email on 117, LinkedIn page on 164, check size on 25.
