Program Overview

The Small Business Innovation Research (SBIR) program was established by Congress in 1982 to fund research and development (R&D) by small businesses of 500 or fewer employees. Eleven federal agencies participate in the program, including the Department of Defense.

The Small Business Technology Transfer (STTR) program was established in 1992 to fund cooperative R&D projects with small businesses and non-profit U.S. research institutions, such as universities. Five federal agencies participate, including the Department of Defense. Both programs focus on projects and services with the potential to develop into a product for military or commercial sectors.

SAM Registration

Before a contract can be awarded, you must be registered in the System for Award Management, or SAM. SAM replaced the Central Contractor Registration (CCR), the Online Representations and Certifications Application, and the Excluded Parties List System. SAM allows firms interested in conducting business with the federal government to provide basic information on their business capabilities and financial information. To register, visit https://www.sam.gov/ If you had an active record in CCR then you have an active record in SAM. You will receive email notifications 60, 30, and 15 days prior to the expiration of the record. You can search for registered entities in SAM by typing the business name or DUNS number into the search box.
