SBIR and STTR: America’s Seed Fund
The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are the largest source of early-stage, non-dilutive funding in the United States: government grants and contracts for small businesses developing innovative technology, with no equity taken. Eleven federal agencies participate, and AI is an explicit priority topic at several, including the National Science Foundation. If you are building an AI product with technical risk, this is the first door to knock on.
How the phases work
Phase I funds feasibility: proving your concept works. Phase II funds development toward commercialization and is substantially larger. The NSF track, known as America’s Seed Fund, is popular with startups because it funds commercial innovation rather than agency-specific needs. Applications are competitive and take real effort; the money is real too.
Beyond SBIR: agencies and defense
Mission agencies run their own AI-relevant programs, and the Department of Defense funnels commercial technology through vehicles like AFWERX. If your AI has a defense or dual-use angle, these move faster than their reputation suggests.
State and local programs
Many states run innovation vouchers, matching grants for SBIR winners, and technology adoption programs for local businesses. Check your state’s economic development agency and local Small Business Development Center (SBDC): they also help with applications, free of charge.
If you are adopting AI rather than building it
Grants skew toward developing new technology. For adoption, look at SBDC advisory programs, workforce development funds for employee training, and R&D tax credits: if you build meaningful custom AI capability internally, part of that work may qualify for the federal research credit. A specialized accountant can tell you quickly.
How to approach it
Start from what you are actually developing, write a one-page project summary, and check sbir.gov and seedfund.nsf.gov for open topics. Treat grants as an accelerator for a plan that already makes sense, never as the reason to build something.
FAQ
Who qualifies for SBIR?
For-profit US businesses with fewer than 500 employees, majority US-owned. Universities can partner, which is the core of the STTR variant.
Does SBIR take equity?
No. SBIR and STTR are non-dilutive: grants and contracts, not investment.
How competitive is it?
Very: acceptance rates are broadly comparable to selective accelerators. A sharp technical story and a real commercialization plan decide the outcome.
