Washington Harbour combines public markets, venture/growth investing, and control private equity in one $4.7B fund, sourcing all of its deals through operating partners from organizations like the NSA, Anduril, and SpaceX’s national security programs. It also builds private equity platforms in government technology and cybersecurity—six formed through eleven acquisitions since 2021—while its leadership, including a co-founder of Nokota Management and a longtime In-Q-Tel investor, brings direct experience connecting institutional finance with national-security technology.
