Based in California, US, and founded in 2024, Theseus operates as a defense and space manufacturing company that focuses on GPS-denied navigation solutions, particularly for drones, aiming to enhance navigation capabilities in challenging environments. Founded by Ian Laffey (CTO), Sacha Lévy, and Carl Schoeller (CEO). In September 2024, Theseus raised seed funding from Pioneer Fund.
