The Small Business Innovation Research (SBIR) program is a competitive federal initiative that encourages small businesses to engage in research and development (R&D). It provides funding to support innovative projects that have the potential for commercialization. The program aims to stimulate technological innovation and foster partnerships between small businesses and government agencies. SBIR is structured in three phases: Phase I focuses on feasibility and proof of concept, Phase II supports further development, and Phase III emphasizes commercialization. This program is crucial for small businesses, as it helps them access funding and resources to bring their innovative ideas to market while contributing to the overall economy.
