FORTUNE — Private equity firm Altamont Capital Partners is beginning to raise its second fund, Fortune has learned. Its target is $600 million, but expectations are that it will either meet or exceed its $750 million soft cap.

Palo Alto-based Altamont was formed in mid-2010 by three former partners of Golden Gate Capital, including co-founder Jesse Rogers. It focuses on middle-market companies in need of significant operational or strategic change, and raised $500 million for a debut fund that is almost fully-committed.

Portfolio companies include snowboard maker Mervin Manufacturing, vinyl window manufacturer Cascade Windows and Taco Bell franchisor Tacala LLC. 

Rogers declined to comment on fundraising, due to regulatory restrictions.
