NSF Releases Annual Call for SBIR/STTR R&D Grant Proposals

Aaron McElweeUtah Innovation Center

The National Science Foundation (NSF) released its 2022 SBIR/STTR Phase I solicitation. The NSF SBIR/STTR programs solicit proposals from small businesses based on groundbreaking scientific discoveries or significant engineering breakthroughs consistent with NSF’s mission to promote the progress of science; to advance the national health, prosperity, and welfare; and to secure the national defense.

Submission Windows

The NSF SBIR/STTR programs have three submission windows throughout the year ending on March 03, 2022; June 30, 2022; and October 26, 2022 by 5:00 p.m. submitter’s time. Unlike deadlines, submission windows allow small businesses the flexibility to submit a full proposal at any time during the submission windows. The proposal submission system will shut down at 5:00 p.m. on each closing date and will then reopen for new submissions the following morning (with the exception of the final submission window which closes in October, when a new or updated solicitation will be anticipated shortly thereafter.)


The NSF SBIR/STTR programs provides non-dilutive, grant funding for the development of deep technologies in nearly all technical areas. Unlike fundamental or basic research activities that focus on scientific and engineering discovery itself, the NSF SBIR/STTR programs support the creation of opportunities to move fundamental science and engineering out of the lab and into the market for societal and economic impacts.

Required Project Pitch

A small business must receive an official invitation via the Project Pitch process to submit a full proposal to this solicitation. The Project Pitch must outline the project objectives, technological innovation, and associated technical risks.

Significant Revisions to the Solicitation

  • NSF increased the SBIR/STTR Phase I funding amount to a maximum of $275,000 to better support the nation’s startups and small businesses, as part of the recent federal adjustment for inflation.
  • The NSF SBIR and STTR Phase I solicitations have been combined into a single document.
  • The new, combined solicitation presents three Phase I submission windows rather than four.
  • Only one Project Pitch submission is permitted per applicant small business per submission window.
