Between 2017 and 2021, 23 percent of proposals submitted to NASA for Phase I SBIR/STTR funding were approved (1,887 awards from 8,360 proposals). The acceptance rate for Phase II proposals, which are generally encouraged or discouraged based on Phase I outcomes, was 58 percent (791 of 1,359 approved).
The number of Phase I proposals varies greatly by state. At the upper end of the range, California-based companies submitted approximately 22 percent (1,847) of all Phase I applications to NASA, and Colorado-based companies submitted 8.6 percent (719). At the other end of the range, South Dakota and Puerto Rico both saw only 1 proposal each, while no company in Alaska, Iowa, Nebraska, or North Dakota submitted a proposal to NASA during this five-year period.
