O’Reilly AlphaTech Ventures (OATV) has quietly closed its second fund with $60 million in capital commitments, Fortune.com has learned. The San Francisco-based venture shop had been targeting $50 million, in line with the $51 million debut vehicle it raised in 2007.

OATV focuses on early-stage IT opportunities, and has really made its mark on the consumer Internet space with investments like Foursquare, Bit.ly and TripIt.

Other deals include OpenX (online ad server), Chumby (WiFi device for consumer market) and OpenCandy (online community for software engineers).

The firm is co-managed by partners Bryce Roberts and Mark Jacobsen. Roberts declined to comment on the fundraise.
