67 Series A developer tools investors

Top 5 Series A developer tools investors, ranked by recent fund activity

Among firms with a published profile and a dated fund or deal in the last 24 months. The rule: 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 A 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. The same rule orders the whole list; it is repeated in the method box.
