$3.6 billion set aside across all Federal agencies for SBIRs & STTRs

What are the SBIR and STTR programs? Heading link

The Small Business Technology Transfer (STTR) and the Small Business Innovation Research (SBIR) are governmental programs that require eligible governmental agencies to set aside a percentage of their budget for small businesses with a strong potential for technology commercialization to engage in R&D. Federal agencies with extramural research budgets over $100 million are required to set-aside a certain percentage of their budget to SBIR, and those with research budgets over $1 billion are required to set aside a portion of these funds for STTR.

SBIR and STTR Critical Differences Heading link

Principal Investigator (PI)

SBIR: PI must be primarily employed (more than half of the PI’s time) with the small business at the time of award and for the duration of the project period (unless a waiver is granted).

STTR: PI may be primarily employed by either the small business concern or the collaborating non-profit research institution at the time of award and for the duration of the project period.


Non-Profit Research Partner

SBIR:  Research partnerships are permitted and encouraged between small businesses and non-profit research institutions. The research institution can complete up to 33 percent of the total effort for a Phase I, and up to 50 percent of the total effort for Phase II.

STTR: Small businesses must formally collaborate with a non-profit research institution. The small business must perform at least 40 percent of the work and the research institution must perform at least 30 percent. The remaining 30 percent may be with the small business concern, the collaborating non-profit research institution, or additional third party/parties.
