SBIR/STTR Phase I Programs is sponsored by National Science Foundation (NSF). The NSF SBIR/STTR programs provide non-dilutive funding for cutting-edge technology innovations that address societal challenges. The Space (SP) topic seeks transformative technologies for sustainable space exploration, habitation, or industrialization, which could include in-space research or manufacturing systems, microgravity applications, and photonic devices and materials.
Smart Health and Biomedical Research in the Era of Artificial Intelligence and Advanced Data Science (SCH) is sponsored by National Science Foundation (NSF) and National Institutes of Health (NIH). This interagency program supports transformative, high-risk/high-reward advances in computer and information science, engineering, mathematics, statistics, behavioral, and/or cognitive research to address pressing questions in biomedical and public health. It encourages scientific and engineering innovations by interdisciplinary teams to develop novel methods to collect, sense, connect, analyze, and interpret data from individuals, devices, and systems, enabling discovery and optimizing health. This includes applying AI in healthcare.
Small Business Innovation Research (SBIR) / Small Business Technology Transfer (STTR) Programs (Phase I) is sponsored by U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA). The USDA SBIR/STTR programs focus on transforming scientific discovery into products and services with commercial potential and/or societal benefit in agriculturally-related areas. This can include app development for agricultural technology, rural development, and smart farming. Phase I aims to demonstrate technical feasibility.
Developer Grants is sponsored by Circle. Circle's Developer Grant initiative supports projects leveraging USDC to create practical solutions. While the 2025 applications are closed for reimagining, they will place greater emphasis on Arc-specific grants and evaluate projects based on alignment with Circle products, team strength, innovation, and impact on the USDC network in 2026.
NSF restarted its SBIR/STTR programs on May 31, 2026 after a multi-month hiatus, with a $250 million FY26 allocation, a Project Pitch portal reopen on June 2, and a first full-proposal deadline of July 27, 2026. The big structural changes: a new Strategic Breakthrough tier that extends invited Phase II companies up to $30 million, and a $40 million pilot for next-generation scientific instrumentation. Phase I tops out at $305K, Phase II at $1.25M, with November 4 and March 4, 2027 windows behind the July 27 first deadline. For deep-tech startups that watched the NIH SBIR omnibus go dark and DARPA pull back on conventional Phase II slots, this is the most consequential reopening of the year — and the Strategic Breakthrough tier is the first time NSF has competed directly with venture capital at growth-stage check sizes.
Read articleThe NSF FY 2026-2030 Strategic Plan reorganizes the agency around three goals, names AI, quantum, and biotech as the critical technologies, codifies Gold Standard Science, and explicitly targets applicant burden. The implications for proposal strategy are bigger than they look.
Read articleCongress appropriated \$8.75 billion for NSF in FY2026, rejecting the administration's proposed 55% cut to \$3.9 billion. But between April and May 2025, DOGE terminated 1,752 grants worth \$1.4 billion, hitting STEM Education (\$888M, 839 grants) and Social, Behavioral and Economic Sciences hardest. Director Panchanathan resigned April 24, 2025; no permanent replacement has been named. Effective December 15, 2025, NSF cut minimum external reviews from three to two, made one internal review allowable, made panel discussions optional, and shrank panel summaries to three to five sentences. Here is what the new NSF actually looks like as a funder, who is being selected against, and how to position a 2026 proposal against the new merit review.
