By Light is proud to announce a formal partnership with the University of South Florida (USF) to accelerate the development of trusted, mission-ready AI solutions in support of national defense.

With By Light’s decades of experience delivering critical technologies across the Department of War (DoW) and USF’s research leadership in AI assurance, cybersecurity, and autonomous systems, this collaboration brings together two organizations deeply committed to advancing innovations that strengthen operational readiness.

USF’s DoW experience and proximity to MacDill AFB, combined with By Light’s advanced simulation and AI capabilities, create a powerful foundation for developing safer, more reliable systems for the Warfighters who depend on them.
