Introduction to the Program:

The NSF SBIR/STTR programs focus on transforming scientific discovery into products and services with commercial potential and/or societal benefit. Unlike fundamental or basic research activities that focus on scientific and engineering discovery itself, the NSF SBIR/STTR programs support the creation of opportunities to move fundamental science and engineering out of the lab and into the market or other use at scale, through startups and small businesses representing deep technology ventures.

The NSF SBIR/STTR programs fund advanced research and development. The programs are designed to provide non-dilutive funding at the earliest stages of technology development.

Synopsis of Program:

The NSF SBIR/STTR programs support moving scientific excellence and technological innovation from the lab to the market. By investing federal research and development funds into startups and small businesses, NSF hopes to build a strong national economy and stimulate the creation of novel products, services, and solutions in the private sector; strengthen the role of small business in meeting federal research and development needs; increase the commercial application of federally supported research results; and develop and increase the US workforce, especially by fostering and encouraging participation by socially and economically disadvantaged and women-owned small businesses.

The SBIR/STTR programs at NSF solicit proposals based on groundbreaking scientific discoveries or significant engineering breakthroughs from the small businesses consistent with NSF's mission to promote the progress of science; to advance the national health, prosperity, and welfare; and to secure the national defense.

The programs are governed by Public Law 114-328 (SBIR/STTR Reauthorization Act of 2017). SBIR/STTR policy is provided by the Small Business Administration (SBA) through the SBA Policy Directive.
