What are the SBIR and STTR Programs?
Known as "America's Seed Fund," these programs provide over $4 billion annually in non-dilutive funding to small businesses for R&D and technology commercialization.
SBIR/STTR Reauthorized Through 2031
The SBIR and STTR programs were successfully reauthorized on April 13, 2026, under the Small Business Innovation and Economic Security Act (S.3971). The programs are now extended through September 30, 2031, ensuring continued agency allocations for small business R&D.
Key Changes Under the New Law
Agencies are required to implement even more rigorous due diligence processes to prevent adversarial foreign influence and ensure funded companies are not backed by countries of concern.
Heavier emphasis is being placed on transitioning research into actual commercial products. Companies that have received multiple Phase I or Phase II awards face stricter transition rate requirements to remain eligible for future funding, curbing so-called "SBIR Mills."
Programs are formally extended through September 30, 2031. As of April 2026, agencies may issue Phase I awards up to $323,090 and Phase II awards up to $2,153,927 without seeking SBA approval — a significant increase over prior limits.
Small Business Innovation Research (SBIR)
The SBIR program is a highly competitive program that encourages domestic small businesses to engage in Federal Research/Research and Development (R/R&D) with the potential for commercialization.
By including qualified small businesses in the nation's R&D arena, high-tech innovation is stimulated and the United States gains entrepreneurial spirit as it meets its specific research and development needs.
Key Requirement
The Principal Investigator (PI) must be primarily employed by the small business (more than 50% of their time).
Small Business Technology Transfer (STTR)
STTR is another program that expands funding opportunities in the federal innovation research and development arena. Central to the program is expansion of the public/private sector partnership to include the joint venture opportunities for small businesses and nonprofit research institutions.
The unique feature of the STTR program is the requirement for the small business to formally collaborate with a research institution in Phase I and Phase II.
Key Requirement
Requires a formal partnership with a non-profit research institution (like a university or FFRDC). The research institution must perform at least 30% of the work.
Key Differences
| Feature | SBIR | STTR |
|---|---|---|
| Partner Requirement | Optional | Mandatory (Research Institution) |
| Principal Investigator | Must be employed by Small Business | Can be employed by Small Business or Research Inst. |
| Work Outsourcing | Max 33% (Phase I) Max 50% (Phase II) | Min 30% by Research Inst. Min 40% by Small Business |
