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 can improve the effectiveness of military personnel and their supporting systems. The CSO process includes a three-phase evaluation: submission of solution briefs, pitch sessions for selected companies, and detailed proposals for those invited to the final phase. 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 reach out to the DIU Acquisition Directorate at acquisition@diu.mil for inquiries.
