This page offers details on NIAID SBIR and STTR program structure, which funding mechanisms we use to support small businesses, and a comparison of SBIR grants and contracts.

Program Structure

The Small Business Innovation Research (SBIR) Small Business Technology Transfer (STTR) programs both seek to stimulate technological innovation and increase private-sector commercialization of technologies developed through federal research and development (R&D) funding and other support initiatives.

The major difference between the two programs is that STTR requires the small business to formally collaborate with a non-profit research institution during the first two Phases of the program, with the goal of fostering cooperation and technology transfer between small businesses and research organizations. SBIR does not have this requirement, though it does allow it.

Some other differences appear in the rules governing the role of the principal investigator and subcontractors. See NIH Small Business Eligibility Criteria for more details and Section III. Eligibility Information in the FOA to which you are applying.

Both programs are structured in three Phases. Note that the stated Phase I and Phase II award levels and project periods are statutory guidelines, not ceilings. The budgets of SBIR and STTR applications will be evaluated to assess the appropriateness of the budget to the timeliness of the research goals and may be reduced on a case-by-case basis as recommended by NIAID reviewers. For more information on each of the Phases, see the NIH Three Phase Program page.

For more detail on the different types of small business applications, see NIH SBIR and STTR Application Types.

For NIAID-specific information on funding support and research topics, see NIAID’s section of the current Program Descriptions and Research Topics document for the SBIR and STTR Omnibus Grant Solicitations for the NIH, CDC, FDA, and ACF. As described on that page, NIAID received a budgetary guideline waiver from the Small Business Administration (SBA) to exceed the hard cap for a limited list of specific topics.

No funding is available for Phase III of the program. Phase III may involve R&D or production contracts for products, processes, or services intended for use by the U.S. government. The NIH Commercialization Accelerator Programm (CAP) or the Regulatory Affairs Support Program in the NIAID Division of Microbiology and Infectious Diseases may be helpful for small businesses that reach Phase III.

Funding Mechanisms

The SBIR and STTR programs award funding through several mechanisms: 

  • Approximately 95 percent of NIH SBIR awards are made through grants, whose topics and research are driven by the awardee.
  • Additional awards are established through contracts, which are procured based on the sponsor’s (NIAID's) needs.
  • A cooperative agreement is another form of funding award that is similar to a grant but includes a high level of involvement from the sponsor.

The table below outlines the differences between grants and contracts in the SBIR program. (The STTR program does not award contracts.) SBIR Grants and Contracts Comparison
