Kleiner Perkins was the most active venture capital firm in Q1 2011 participating in 23 new and follow-on financings in US-based companies followed closely by New Enterprise Associates.  It was a busy quarter for many VC firms with 27 firms participating in at least 7 financing deals in the quarter.  Note: You can get the entire Q1 2011 63 page report here.

In this quarter, we also saw several micro-venture capital funds (lovingly but inappropriately often referred to as Super Angels) also break into the most active ranks.  Note: within CB Insights, we track angel investors as well but once an angel investor is investing other people’s money and not just their own, we classify them as VC firms.
