Defense tech startup Epirus, which specializes in anti-drone systems, has raised an oversubscribed $250 million Series D, it told TechCrunch.

Epirus, based in Torrance, California, was previously valued at $1.35 billion for its $200 million Series C in 2022, per its announcement at the time. Epirus did not give a specific valuation for this round, but confirmed to TechCrunch that it is over $1 billion. (Bloomberg reported in January 2025 that Epirus was raising this round at a lower valuation than its Series C.)
