NSF SBIR/STTR Programs – FY 2026 Funding Overview

Program Overview

The NSF Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Programs provide funding to startups and small businesses developing high-risk, high-impact technologies with strong commercial potential.

Administered through the National Science Foundation Directorate for Technology, Innovation and Partnerships, the programs are designed to help early-stage companies translate scientific and engineering breakthroughs into commercially viable technologies that strengthen U.S. competitiveness, security, and economic growth.

The NSF SBIR/STTR programs focus specifically on supporting deep technology innovation at early stages of technical and commercial development.

Program Objectives

The NSF SBIR/STTR programs are intended to support research and development activities that advance emerging technologies toward commercialization while strengthening the broader U.S. innovation ecosystem.

NSF evaluates proposals based on three primary review criteria:

• Intellectual Merit
• Broader Impacts
• Commercial Potential

Successful projects are expected to demonstrate not only technical innovation, but also a credible path toward market adoption, customer engagement, follow-on funding, and long-term business viability.

Funding Mechanisms Available

The NSF SBIR/STTR program includes four primary funding mechanisms:

• Phase I Awards
• Phase II Awards
• Fast-Track Awards
• Supplemental Awards

Phase I awards are generally intended to establish technical feasibility and early commercial validation. Phase II awards support continued research and development efforts tied to commercialization readiness.

Fast-Track proposals allow companies to submit combined Phase I and Phase II plans intended to accelerate development timelines for technologies with strong commercialization potential.

SBIR vs. STTR: Key Differences

While both SBIR and STTR programs support startup innovation, there are important structural differences between the two mechanisms.

• SBIR: Partnerships with research institutions are permitted but not required.
• STTR: Applicants are required to issue a subaward to a nonprofit research institution.

These structures are intended to support commercialization pathways while encouraging collaboration between startups, universities, and research organizations where appropriate.

Why NSF SBIR/STTR Funding Matters

Early-stage deep technology companies often face significant technical, operational, and financing risks before commercial markets are fully established.

Programs such as NSF SBIR/STTR help companies advance foundational research and prototype development while reducing some of the early-stage capital barriers associated with emerging technologies.

The programs also reflect increasing federal interest in supporting:

• Critical and emerging technologies
• Advanced manufacturing
• Industrial biotechnology
• Artificial intelligence and data systems
• Clean energy and sustainability technologies
• National competitiveness and supply chain resiliency

Cost Sharing Requirements

Voluntary committed cost sharing is prohibited under this funding opportunity. Applicants should not include voluntary matching contributions as part of proposal submissions.

Application Process and Deadlines

For Phase I submissions, applicants are required to submit a Project Pitch before submitting a full proposal. NSF uses the Project Pitch process to determine whether the proposed innovation aligns with program objectives and eligibility requirements.

Upcoming full proposal deadlines include:

• July 27, 2026
• November 4, 2026
• March 4, 2027
• July 7, 2027
