Crosspoint Venture Partners

John Mumford co-founded Crosspoint Venture Partners in 1970. He served as the firm's general partner and primary investment decision-maker throughout its most active decades. Mumford was among the earliest venture capitalists to establish an institutional partnership on the West Coast, building a track record that spanned enterprise software, networking, and internet infrastructure.

Crosspoint's current investment activity is not publicly documented. The firm's last confirmed fundraise occurred in the early 2000s, and it has made no public announcements regarding new funds or investments in recent years. Without disclosed deployment or team updates, the firm's active status remains unclear to outside observers.

Crosspoint's historically disclosed portfolio includes Foundry Networks (IPO 1999), Ariba (IPO 1999), and Brocade Communications (IPO 1999). Each of these companies became significant enterprise technology players in the late 1990s and early 2000s. The firm also backed Avanex and several other infrastructure and software companies during the same period, per public filings and industry records.
