DHS’s SBIR Program has issued a pre-solicitation to help small businesses prepare for an upcoming SBIR solicitation; it is for planning only and DHS is not accepting proposals at this time. Offerors should review the attached pre-solicitation carefully because final requirements may differ and noncompliance could negatively affect evaluation or eliminate a proposal. Before future proposal submission, offerors must register with SAM.gov and the SBA Company Registration Database, and SAM registration can take several weeks, so early initiation is recommended. Entities majority-owned by multiple venture capital operating companies, hedge funds, or private equity firms are ineligible, and Phase I applicants must meet or exceed the SBA Phase II Transition Rate Benchmark under the May 3, 2023 policy directive. Unsolicited proposals will not be accepted.
