QuadSAT

Defence Tech·Series A

QuadSAT is a Denmark-based defence technology company founded in 2017 by Joakim Espeland (CEO) and Andrian Buchi (CTO), who met as mechanical engineering students at VIA University College. Espeland, a Norwegian RF engineer with five years of experience in maritime satellite communications, identified inefficiencies in satellite antenna testing that required expensive ship deployments. The company develops drone-based RF measurement and antenna testing systems, with traction including operational campaigns with OneWeb and the European Space Agency. QuadSAT maintains a UK registered office in London to serve NATO-aligned defence customers across Europe. The company raised €9M in Series A funding led by IQ Capital in 2023, followed by a €5M extension in 2025 led by Join Capital and North Ventures.
