SBIR and STTR in 2026: America's Seed Fund, Back After the Lapse

If you run a U.S. technology startup, SBIR and STTR are the closest thing the federal government has to a seed fund for you: research-and-development money that takes no equity, awarded competitively, across essentially every technical field the government cares about. And 2026 is an unusual moment to learn about them, because the programs just came back from the longest interruption in their history.

The 2026 story: lapse and reauthorization

SBIR and STTR run on congressional authorization, and that authorization expired on September 30, 2025 without a renewal in place. For roughly six months, new solicitations and awards froze government-wide — NIH formally terminated its open SBIR/STTR funding announcements, NSF paused its America's Seed Fund solicitations, and defense programs postponed awards. The freeze ended when the Small Business Innovation and Economic Security Act was signed on April 13, 2026, reauthorizing both programs through September 30, 2031. Agencies have been restarting solicitations since, which means a wave of fresh openings is working through the system as programs come back online.

What SBIR and STTR are

Congress created SBIR in 1982 and STTR a decade later, requiring federal agencies with large research budgets to set aside a slice specifically for small businesses. Eleven agencies participate — including the Department of Defense, HHS/NIH, the National Science Foundation, the Department of Energy, and NASA — and each runs its own competitions on its own calendar. The money is non-dilutive: it is an award or contract for R&D work, not an investment. No equity, no board seat, no repayment.

The three phases

• Phase I — feasibility. A modest award to prove the concept has technical merit, typically over a matter of months.
• Phase II — development. A substantially larger award to build on successful Phase I results, typically over about two years.
• Phase III — commercialization. Not funded by the SBIR set-aside itself; this is where the technology transitions to regular federal contracts or the commercial market, with meaningful advantages for companies that developed the work under SBIR.

Who is eligible

The core requirements: a for-profit U.S. small business with fewer than 500 employees, majority owned and controlled by U.S. citizens or permanent residents (with limited exceptions some agencies elect for venture-backed firms). The work must be performed primarily in the United States, and the principal investigator has employment requirements that differ slightly between the two programs.

What makes STTR different: an STTR award requires a formal collaboration with a nonprofit research institution — a university or a federal lab — with a meaningful share of the work performed by each partner. If your technology grew out of academic research and the lab is still involved, STTR is often the natural fit; if the company can carry the R&D itself, SBIR is the wider door.

What the 2026 law changed

The reauthorization was not a clean extension — it came with reforms worth knowing before you apply:

• Strategic Breakthrough awards — a new, much larger Phase II follow-on vehicle (with a ceiling in the tens of millions) at agencies with the biggest SBIR budgets, aimed at later-stage technologies with demonstrated commercial or national-security pull. Prior Phase II performance is a prerequisite.
• Proposal caps — beginning in fiscal year 2027, agencies will limit how many Phase I and Phase II proposals a single company can submit, a response to firms that win many awards without commercializing.
• Tighter national-security due diligence — expanded screening of applicants' foreign ties, ownership, investors, and licensing relationships, with particular scrutiny of connections to countries of concern. Expect more disclosure paperwork, and get your ownership and IP records clean before you need them.

Where to find the openings

The canonical portal is SBIR.gov, which aggregates topics across all participating agencies. Some agencies also publish their SBIR announcements on Grants.gov — NIH's flow through there, and you will find them in this site's agency listings — while others, notably the Department of Defense, run their own submission portals. Wherever the topic lives, the structure above is the same. And because agencies are restarting a backlog of solicitations this year, watching what posts and closes matters more than usual.
