Felicis Ventures, the super angel investment firm that was founded by former Googler Aydin Senkut back in 2006, has raised $52 million for a new fund according to an SEC filing that surfaced on Friday.

The fund, named Felicis Ventures III, is $12 million bigger than the firm’s previous institutional fund ($40 million raised in August 2010).

According to an earlier article in the Wall Street Journal, the latter fund itself followed a $20 million fund by Silicon Valley investor Ron Conway (SV Angel) and a $8.5 million round provided by another former Google exec, Chris Sacca – who, coincidentally, now runs his own super angel fund, called Lowercase Capital.

Senkut joined Google in 1999 and left the Internet search and advertising company at the end of 2005, a little more than a year after Google went public. He obviously departed Google a wealthy man, and invested in several dozens of startups as an angel investor even before starting Felicis Ventures.

With a relatively small team and by leveraging Senkut’s extensive Silicon Valley network, Felicis has made investments in companies like Aardvark, AppJet and SayNow (all acquired by Google), GeoAPI and Posterous (both acquired by Twitter), Chomp (acquired by Apple), Karma (just acquired by Facebook), Mint (acquired by Intuit), Webs (acquired by VistaPrint), Milo (acquired by eBay), Mob.ly (acquired by Groupon), Powerset (acquired by Microsoft) and Tapulous (acquired by Disney).

As you can tell, they’ve had quite a few exits already.

Other startups in its portfolio that are still flying solo include Angry Birds maker Rovio, Bump, Fitbit, Erply, DailyBooth, Zaarly, Foodspotting, Weebly and DISQUS.

Other well-financed U.S. super angel funds include the aforementioned Lowercase Capital, K9 Ventures, Dave McClure’s 500 Startups, CrunchFund and Floodgate.
