Powered by a network of federal agencies, entrepreneur support organizations, and the Small Business Administration (SBA), America's Seed Fund advances federal missions and fosters a culture of innovation in the United States.
As the sponsoring agency for America's Seed Fund, SBA guides the participating agency's implementation of their SBIR/STTR programs, monitors and reports on program progress to Congress, and aggregates agency solicitation information. The SBA's expert staff supports the program by administering the Policy Directive and liaising with participating federal agencies and technology entrepreneurs.
Each participating federal agency administers its own SBIR/STTR program within guidelines established by Congress. As of April 2026, agencies may issue a Phase I award (including modifications) up to $ 323,090 and a Phase II award (including modifications) up to $2,153,927 without seeking SBA approval. Any award above those levels will require a waiver.
Agencies considering this authority should review SBIR/STTR Policy Directive §7(i)(4) for additional information. Read the Policy Directive

NSF X-Labs is unlike any NSF program in the agency's history: it runs on Other Transaction Authority, not a grant; it funds teams up to $1.5M in Phase 0 and as much as $50 million per year in Phase 1; and it demands an 8-page written proposal followed by an invitation-only oral defense in which NSF refuses to look at what you wrote. The Quantum Systems topic closes July 24, 2026. Here is what X-Labs actually is, why the structure signals a new NSF, and who is positioned to win a DARPA-style award from an agency that has never operated this way before.
Read articleRelease 6's SBIR topics got the attention. Its three STTR topics — SHIELDER, fuel-flexible electric propulsion, and hypersonic wind tunnel noise diagnostics — are all Direct-to-Phase-II, all require a research institution to perform at least 30 percent of the work, and all close October 21, 2026. The feasibility gates are the real filter.
Read articleDPA26BZ06-DV023 is a Direct-to-Phase-II SBIR paying $700,000 over 18 months plus a $500,000 option. The physics demands 256x more transmit power than the systems that qualify you to compete, and DARPA will not accept modeling alone as proof. Here is the eligibility wall, the five engineering problems, and who can realistically win it before the October 21 close.
