Start With Your Technology and Application Stage
A useful SBIR or STTR shortlist starts with the problem you can solve and the work you have already completed. Identify the agency whose topic fits that work, then check the phase and applicant requirements in its official notice. A relevant title alone does not establish that your company can apply. The examples below were checked on September 13, 2026 and rechecked on October 9, 2026. They cover selected DARPA windows, not every federal solicitation. For the program authorization and legislative background, see our SBIR/STTR reauthorization guide.
Open as of September 13, 2026
The official DARPA topics page listed Hoboken - SBIR XL (DPA26BZ05-DV018) and Semantically-Aware ISR (DPA26BZ05-DV019) as open from August 26 through September 23, 2026 (closed), at 12:00 PM Eastern. On October 9, 2026 the same page marked both topics closed as of September 23. Open the topic instructions from that page before committing proposal time. Check the technical objective, phase, eligibility, submission process and any amendments. The closing date is only one part of deciding whether a topic fits.

Build a Shortlist You Can Act On
Start with our SBIR search or STTR search. Narrow the results to your technology and open each promising record. For each candidate, record the official application link, whether submissions are open or upcoming, the deadline and time zone, the phase, who can apply, and the required registrations. Read amendments before planning the submission. Keep the opportunity that best matches your work at the top of your list. If a window has closed, look for the agency's next topic release rather than preparing a proposal against an expired notice. Check the issuing agency again before you submit.
