The current SBIR/STTR Phase I solicitation submission window end date has been extended to 5:00 PM submitter’s local time on Monday, March 4, 2024. Stay tuned for new SBIR/STTR submission opportunities.
Submission windows, unlike deadlines, allow small businesses to submit a full proposal during the specific dates listed at the top of this document.
The proposal submission system, Research.gov, will stop accepting proposals at 5:00 p.m. “submitter’s time” on the submission window closing date, but, with the exception of the last submission window, will then reopen for new submissions the following morning.
After the last submission window closes, a new or updated solicitation may be posted shortly thereafter.
Please note: The NSF SBIR/STTR program does not support clinical trials or proposals from companies whose commercialization pathway involves the production, distribution, or sale by the company of chemical components, natural or synthetic variations thereof, or other derivatives related to Schedule I controlled substances.
