Khosla Ventures last week announced that it has closed its fourth general fund with $1.05 billion in capital commitments. A few notes, based on conversations with multiple sources:

1. The vehicle was oversubscribed, with over 90% of commitments coming from existing LPs. Considering that former cornerstone backer CalPERS decided not to re-up, that means a lot of increased commitments.

2. Almost all of Khosla’s LPs are institutional investors. One notable exception is John Doerr, who has personally invested in both Funds III and IV (and maybe the $300m seed fund, I’m not certain). For the uninitiated, Doerr is a partner with Kleiner Perkins Caufield & Byers, the venerable venture firm where Khosla used to work.

3. Khosla made some news in August, when it was first reported that junior partners Alex Kinnier and Jim Kim had left the firm. This followed the earlier departure of Gideon Yu, the ex-Facebook exec who had led Khosla’s investment in Square (he’s now chief strategy officer with the resurgent San Francisco 49ers, and doesn’t list Khosla Ventures on his LinkedIn profile). One returning LP tells me that it knew about (at least some of) the departures before making its final commitment, suggesting that the moves were made known internally (at least to large LPs) long before they became known externally.
