All 15 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 space and aerospace 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 dated activity, which is a fund filing or announcement, a deal or portfolio news (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 15 rows: stage 15, sector 15, fund size 14, website 15. In the paid file: named decision-makers on 13 rows, firm email on 4, LinkedIn page on 10, check size on 2. ## Questions ### How many Series B space investors in the US are there?
