Top 5 Series B space investors in the US, ranked by our activity score
Among firms with a published profile and dated activity in the last 24 months. The rule: 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. The same rule orders the whole list; it is repeated in the method box.
