All 26 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 robotics 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 (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 B 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 26 rows: stage 26, sector 26, fund size 22, website 26. In the paid file: named decision-makers on 25 rows, firm email on 13, LinkedIn page on 19, check size on 4. ## Questions ### How many Series B robotics investors are there?
