The NSF Small Business Innovation Research (SBIR) Phase I program supports early-stage, high-risk technological innovations developed by U.S. small businesses. Unlike traditional academic research grants, SBIR Phase I awards are structured specifically to help companies establish the technical feasibility of transformative products, processes, services, or software tools with strong commercial potential. NSF’s focus is on deep-technology innovation—projects rooted in fundamental science or engineering advances rather than incremental improvements or routine product development. 

Eligible technologies span a wide array of fields, including artificial intelligence and machine learning, advanced materials, biotechnology, medical devices, environmental technologies, photonics, quantum information science, energy and sustainability innovations, flexible electronics, robotics and automation, cyber-physical systems, advanced manufacturing, and novel computational tools. NSF seeks innovations that could create entirely new markets or dramatically reshape existing industries. 

NSF SBIR Phase I awards typically provide up to $275,000 over 6–12 months, supporting feasibility studies, early prototyping, algorithm or software development, bench-scale experiments, initial user research, or validation of core technical hypotheses. Because NSF does not fund clinical trials, manufacturing scale-up, or purely commercial activities, proposals must emphasize scientific novelty, technical risk, and clear research objectives. Commercialization is important—but the Phase I work must center on proving technical merit. 

Eligibility is restricted to U.S.-owned, for-profit small businesses with fewer than 500 employees, with the Principal Investigator primarily employed by the company during the project. Companies may partner with universities, research institutions, or consultants as subcontractors, but the small business must perform a majority of the research. 

Strong NSF SBIR Phase I proposals articulate: 

• The transformative scientific or engineering innovation 

• The key technical risks and how Phase I will address them 

• A compelling commercialization vision and societal benefit 

• Evidence of a capable technical team 

• A clear Phase I work plan and success metrics 

Successful teams often transition to SBIR Phase II, which provides up to $1 million or more for prototype development and market validation.
