Place: head office in Washington. - Order: Activity score out of 100: recency of the latest dated activity, which is a fund filing or announcement, a deal or portfolio news (40: full marks within 3 months, then stepping down at 6, 12 and 24 months), stage focus (15: all of it when pre-seed 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 (20) and completeness of the public record (10). 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 14, fund size 13, website 15.
