The Small Business Innovation Research (SBIR) program is a competitive federal initiative that encourages small businesses to engage in research and development (R&D) with the potential for commercialization. It provides funding to support innovative projects that address specific government needs, fostering technological advancement and economic growth. SBIR is structured in three phases: Phase I focuses on feasibility and innovation, Phase II supports further development, and Phase III aims for commercialization. Various federal agencies, including the Department of Defense and the National Institutes of Health, participate in the program, making it a vital resource for small businesses seeking to innovate.
