US technology businesses can access federal grant funding through NSF SBIR, DOD technology programmes, DOE advanced research, and sector-specific innovation funds. This guide covers the main programmes and how to identify the right fit.
The US federal government is the largest funder of early-stage technology development in the world - and a meaningful share of that funding reaches small businesses directly through SBIR, STTR, and agency-specific R&D programmes. For technology companies developing novel solutions in areas with federal interest - which is broader than most people assume - the question isn't whether funding exists but which agency's priorities align with your technology.
NSF's SBIR/STTR programme (America's Seed Fund) is the best-known route for deep tech companies - AI, robotics, semiconductors, quantum computing, advanced materials, biotech, and clean energy. Phase I awards are $275,000 for a twelve-month feasibility study; Phase II awards are up to $1 million. NSF is technology-agnostic - it funds any area of science and engineering - but requires genuine scientific or technological innovation. NSF has been particularly active in AI/ML, cybersecurity, climate technology, and semiconductor technology in recent years.
DARPA funds high-risk, high-reward research with transformational potential. It doesn't run a standard SBIR programme - instead, it issues Broad Agency Announcements (BAAs) for specific research areas. Award sizes are larger than standard SBIR and timelines more flexible, but DARPA expects breakthrough results. Small companies that have won DARPA contracts often describe it as transformational - the funding, the network, and the validation are all significant. DARPA BAAs are listed on SAM.gov; monitoring them requires domain-specific knowledge to identify relevant opportunities.
The Department of Defense runs the largest SBIR programme in the federal government - across Army, Navy, Air Force, SOCOM, MDA, DTRA, and others. DOD SBIR solicitations are published twice yearly (plus Open Topics), covering technologies from materials and manufacturing to AI, autonomy, cyber, and biotechnology. The DOD's transition focus - wanting SBIR technologies to become military programmes of record or commercial dual-use products - is different from civilian agency SBIR. Understanding which acquisition programme your technology could serve helps write a more compelling DOD proposal.
The Department of Energy's SBIR/STTR programme covers energy technology, advanced manufacturing, basic science, and nuclear. ARPA-E funds transformational energy technology with higher risk tolerance than standard SBIR. The DOE's Office of Technology Transitions helps SBIR awardees commercialise into private markets. For clean energy technology companies, DOE SBIR - combined with state clean energy grant programmes and IRA incentives - creates a substantial funding stack.
