The Defense Innovation Unit (DIU) of the Department of Defense is seeking proposals for its Commercial Solutions Opening (CSO), aimed at enhancing military capabilities through innovative commercial technologies. This opportunity invites both traditional and nontraditional defense contractors to submit prototype projects that align with national security objectives, focusing on technologies that contribute to the sustainment of global peace and U.S. national security. The CSO process consists of three phases: submission of a solution brief, a pitch session for selected companies, and a full proposal submission for those invited, with successful prototypes potentially transitioning to production without further competition. Interested parties can find more information and updates on Areas of Interest on the DIU website at https://www.diu.mil/work-with-us, and are encouraged to contact DIU at info@diu.mil for inquiries.
