FORTUNE -- The Social+Capital Partnership, a venture capital firm founded by former Facebook exec Chamath Palihapitiya, is seeking to raise $325 million for its second fund, according to a regulatory filing. It also is planning to raise a $60 million "principals fund" that presumably would come from the personal accounts of Palihapitiya and other firm partners.
The Palo Alto, Calif.-based firm raised $275 million for its debut fund less than two years ago, with Facebook (FB) serving as its "lone corporate investor."
That's a lot of capital to have invested so quickly, although the firm has a stage-agnostic strategy that puts it into larger deals like Yammer's $80 million Series E round just months before the company agreed to be acquired by Microsoft (MSFT) for $1.2 billion. It also participated in a recent $444 million round for SurveyMonkey, which was led by Tiger Global Management (whose founder, Chase Coleman, is an LP in Social+Capital Partnership's first fund).
Other recent investments include Syapse, Flatiron Health, Twitspark and Open Air Publishing.
Social+Capital has two partners in addition to Palihapitiya: Ted Maidenberg and Mamoon Hamid, both of whom previously were with U.S. Venture Partners.
