Epirus is a defense technology startup pioneering long-pulse high-power microwave technology to revolutionize electronic warfare. By integrating artificial intelligence and advanced electronics, the company develops software-defined, scalable defenses capable of neutralizing drone swarms, cyber-electronic attacks, and radar-jamming threats with unmatched precision. Unlike traditional kinetic systems, Epirus’ solutions deliver cost-effective, adaptive protection while minimizing collateral damage. With its AI-driven approach, Epirus is shaping the future of directed energy warfare for modern defense and security challenges.
Epirus has raised $250 million in a Series D funding round led by 8VC and Washington Harbour Partners with participation from StepStone Group, funds and accounts advised by T. Rowe Price Investment Management, Gaingels, and others. Epirus was previously valued at $1.35 billion for its $200 million Series C in 2022.
Epirus, Torrance, California, United States, was founded in 2018 by Bo Marr, Grant L. Verstandig, Joe Lonsdale, John Tenet, Max Mednik, and Nathan Mintz. In 2022, the company joined the unicorn club. Epirus operates in the defense, cybersecurity, and commercial markets, providing advanced high-power microwave (HPM) technology for electronic warfare, critical infrastructure protection, and counter-drone applications across military and civilian sectors. “With our capital and talent and the right partnerships with US DoD to continue to advance Epirus’ technology, it will quickly become critical for defending aircraft, ships and even satellites and space-based platforms—and determinative for the future of warfare,” said Epirus founder and 8VC managing partner Joe Lonsdale.
