The San Francisco-based firm has tapped 77 investors for the sidecar, which is presumably a companion fund set aside for the executives of its portfolio companies.
The firm raised $1.2 billion for its fourth main fund, Vector Capital IV, which closed last year.
The firm, which specializes in providing growth equity for spinouts, is on a slightly faster investment pace than last year. It has backed four companies so far this year, the same number it did for all of 2007, according to data from Thomson Reuters (publisher of PE Week).
Representatives from the firm were not immediately available for comment. —Alexander Haislip
