Platform One, with support from its marketplace manager, The Applied Research Institute (ARI), is initiating a long-term, open call for solutions to support the DoD in quickly delivering high-quality, secure software with accelerated delivery times. The solutions will support or enable the delivery of resilient software capability at the speed of relevance, ensuring the DoD remains agile and responsive to emerging threats and opportunities. Specifically, Platform One seeks to obtain innovative solutions or potential capabilities that fulfill requirements, close capability gaps, or provide potential technological advancements. Innovative solutions encompass technologies, processes, or methods (including research and development) that are newly developed or applied in a novel way as of the submission date. This initiative, entitled the “Platform One Solutions Marketplace” (P1SM) will solicit, collect, assess, and curate hardware, software, or service solutions and make those solutions available through rapid acquisition pathways. This approach aims to foster innovation and expedite the integration of cutting-edge technologies into the DoD's operational framework, enhancing its ability to deliver software at the speed of relevance.
