• More About Us: We're building the next generation of aerospace, defense and critical industry technologies with a seasoned team of mission-focused individuals. We were founded in June 2022 and our goal is to become the platform where world-class engineers come to solve critical, real-world problems. We use agile engineering approaches which enable rapid prototyping, deep partnerships with the defense industry ensuring real-world application, and our newly-invented Coherence platform (through which we’ve made a fundamental breakthrough) improves sensor performance and decision-making in real-time. As of April 2025 we have raised $490M (including a $275M Series C at a $2B valuation) from some of the most prominent VC funds and investors including Accel, NEA, 8VC, and Valar. With a managing team that includes Epirus’ founding members (responsible for building a $1.5B company from scratch) + key drivers from Palantir (instrumental in Palantir’s growth to $1B in revenue), we are well-positioned to become one of the fastest growing companies to date!
