NSF Small Business Innovation Research / Small Business Technology Transfer Phase II Programs
ClosedU.S. National Science Foundation
Updated: Oct 30, 2025
Summary
The NSF SBIR/STTR programs aim to transition scientific and technological innovations from research to market by providing non-dilutive funding to startups and small businesses, particularly those led by socially and economically disadvantaged individuals. Eligible applicants include small businesses that meet specific size requirements and have previously received an NSF SBIR/STTR Phase I award, with proposals due within 6 to 24 months after the Phase I award start date. Applications must be submitted through the NSF's proposal submission process, adhering to guidelines outlined in the SBIR/STTR Policy Directive.
Full Description
Description
- The innovations are underpinned and enabled by a new scientific discovery or meaningful engineering innovation.
- The innovations still require intensive technical research and development to be fully embedded in a reliable product or service.
- The innovations have not yet been reduced to practice by anyone and it is not guaranteed, at present, that doing so is technically possible.
- The innovations provide a strong competitive advantage that are not easily replicable by competitors (even technically proficient ones).
- Once reduced to practice, the innovations are expected to result in a product or service that would either be disruptive to existing markets or create new markets/new market segments.
