All 17 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 marketplaces as a focus on its own site, or we observed it in the firm's portfolio. Place: head office in California. - 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 17 rows: stage 14, sector 17, fund size 16, website 17. In the paid file: named decision-makers on 15 rows, firm email on 6, LinkedIn page on 10, check size on 3. ## Questions ### How many marketplace investors in California are there?
