Small Business Programs

The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Program supports innovative research conducted by small businesses that has the potential for commercialization.

The funds for this program are ‘set-aside’ and therefore do not compete with the regular research, training, or other special programs supported by the Institute. The set-asides are set to increase over the next few years, and applicant success rates are highest for this type of funding.​

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Funding Mechanisms


SBIR (R43/R44) grants are awarded to support research/research and development (R/R&D) efforts where the principal investigator is an employee of a small business.

STTR (R41/R42) grants support formal cooperative R/R&D efforts between small businesses and U.S. research institutions.

Application Types (Phase I, Phase II, Fast-Track, Phase IIB)

A Phase I SBIR (R43) or STTR (R41) grant is awarded to support studies establishing the technical/scientific merit and feasibility of the proposed R/R&D efforts.

Upon completion of Phase I, a Phase II SBIR (R44) or STTR (R42) grant may be awarded to support continuation of the R/R&D efforts initiated in Phase I. Phase II grants may be considerably larger than Phase I grants and require submission of a commercialization plan.

Fast-Track is an alternative pathway which expedites the decision and award of Phase II funding for scientifically meritorious applications that have a high potential for commercialization. The goals for Phase II must be clear, and the likelihood of Phase I success must be high, to be competitive. Fast-Track requires simultaneous submission of Phase I and Phase II applications. See NOT-OD-06-004 and the SBIR/STTR SF424 (R&R) Application Guide for more information.

NIDDK also offers the opportunity to apply for Phase IIB, Competing Renewal, SBIR grants, following completion of Phase II. These grants are offered to support projects that require regulatory approval for the product or service being developed or to support complex instrumentation, clinical research tools, and behavioral interventions/treatments.
