All 30 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 developer tools 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 UK (15: full marks when the firm names the UK as where it invests, half when it says Europe or 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 30 rows: stage 28, sector 30, fund size 15, website 30. In the paid file: named decision-makers on 29 rows, firm email on 18, LinkedIn page on 20, check size on 18. ## Questions ### How many developer tools investors in the UK are there?
