The National Science Foundation Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Programs provide funding for innovation. The SBIR program funds high-risk, high-reward research and development at small businesses, aiming to bridge the "valley of death" between discovery and commercialization. It provides $120 million annually in Phase I and Phase II awards. Proposals are reviewed based on both the technical and commercial merit and must demonstrate potential for commercial and societal benefits. The NSF SBIR program focuses on enabling market-driven innovation through strategic partnerships and networks that can attract further non-SBIR funding.
