Activity in this selectionMay 31, 2026 · May 1, 2026

Washington Harbour Partners invests in technology businesses addressing US economic and national-security needs, including space, autonomous systems, cybersecurity, energy and the industrial base.

Its focus is on commercial technologies that fill specific mission gaps for government and enterprise customers. The investment team works alongside operating partners and advisers with experience in these sectors.

The firm emphasises access to end customers and understanding how the technology will be used. That is particularly relevant for founders whose route to scale depends on government procurement, defence requirements or deployment within critical infrastructure.
