The NSF STTR Phase I program supports collaborative R&D between small businesses and nonprofit research institutions, accelerating the transfer of cutting-edge scientific discoveries into commercially viable technologies. Unlike SBIR, where small businesses perform the majority of the work, STTR requires a formal partnership in which at least 30% of the research is conducted by a university, federal laboratory, or nonprofit research organization. This structure makes STTR especially well-suited for early technologies emerging from academic labs, enabling companies to leverage deep scientific expertise while advancing high-risk, high-reward innovation. 

STTR Phase I awards focus on establishing technical feasibility for transformative concepts in areas such as artificial intelligence, advanced materials, biotechnology, medical devices, photonics, quantum technologies, environmental engineering, and clean energy systems. Proposals must emphasize novelty, scientific merit, and the potential for significant commercial impact. A clear intellectual property strategy is also essential, since the program is designed to move fundamental research toward real-world application and market readiness. 

Eligibility requires that the small business be U.S.-owned, independently operated, and employ fewer than 500 people. The partnering research institution must be U.S.-based and meet NSF’s criteria for nonprofit research entities. The Principal Investigator may be primarily employed by either the small business or the research institution, but both organizations must demonstrate the ability to carry out their respective project roles. STTR Phase I awards typically provide up to $300,000 over 6–12 months, with flexibility for high-impact technical milestones and early customer discovery. 

Competitive proposals articulate a transformative vision, rigorous technical objectives, a defensible commercialization pathway, and a highly integrated collaboration plan between the company and its research partner. Because STTR projects require strong coordination and clear division of responsibilities, narrative clarity and project-management structure are essential.
