The Small Business Innovation Research (SBIR) program is the federal government's largest source of early-stage R&D funding for small businesses. Eleven federal agencies participate in SBIR, collectively awarding billions of dollars annually to small businesses developing innovative technologies. Texas businesses — particularly in energy, defense, healthcare, aerospace, and technology — are strong candidates for SBIR awards.
This guide explains how the SBIR program works, which federal agencies are most relevant for Texas businesses, published eligibility criteria, and how to apply.
How SBIR Works
SBIR is structured in three phases:
- Phase I (Feasibility): Awards of up to $150,000-$275,000 (varies by agency) for 6-12 months of feasibility research. This phase determines whether the proposed innovation has technical merit and commercial potential.
- Phase II (Development): Awards of up to $1 million-$1.75 million for 24 months of full R&D. Only successful Phase I awardees are eligible for Phase II.
- Phase III (Commercialization): No SBIR funding in this phase. The business uses private capital, other government contracts, or agency procurement to commercialize the technology. Phase III does not involve SBIR set-aside funds.
SBIR awards are grants or contracts (depending on the agency), not loans. The business retains intellectual property rights to the technology it develops.
STTR: The Research Partnership Variant
The Small Business Technology Transfer (STTR) program is a companion to SBIR. The key difference is that STTR requires a formal partnership between the small business and a research institution (university, federal lab, or nonprofit research organization). The research institution must perform at least 30% of the work. Texas universities — UT Austin, Texas A&M, Rice, UT Southwestern, and others — are active STTR partners.
Published Eligibility Criteria
- Small business: Must be a for-profit U.S. business with 500 or fewer employees.
- Majority U.S. owned: More than 50% owned by U.S. citizens or permanent residents, or by other small businesses that are majority U.S. owned.
- Principal researcher: The primary researcher must be employed by the small business at the time of the award (SBIR). For STTR, the PI can be from either the small business or the research institution.
- Innovation focus: The proposed project must involve scientific or engineering research with commercial potential.
Key Agencies for Texas Businesses
Department of Defense (DOD)
DOD is the largest SBIR funder. Texas businesses near military installations — Fort Bliss, Fort Cavazos, Joint Base San Antonio, Naval Air Station Corpus Christi — and defense contractors in the DFW area are natural fits for DOD SBIR topics in cybersecurity, autonomous systems, sensors, communications, and materials.
Department of Energy (DOE)
DOE SBIR is highly relevant for Houston-area energy businesses. Topics cover oil and gas technology, renewable energy, grid modernization, carbon capture, hydrogen, and energy storage.
National Institutes of Health (NIH)
NIH is the second-largest SBIR funder. Texas Medical Center in Houston, UT Southwestern in Dallas, and other major medical research centers create a strong ecosystem for health-tech and biotech SBIR/STTR applications.
NASA
Johnson Space Center in Houston makes NASA SBIR particularly relevant for Texas businesses in aerospace, materials, life support systems, and space technology.
NSF
NSF SBIR (called America's Seed Fund) covers a broad range of technology areas. Austin and DFW technology startups frequently pursue NSF SBIR funding.
How to Apply
Step 1: Identify Relevant Topics
Each agency publishes SBIR/STTR solicitations with specific research topics. Review solicitations for topics that align with your technology and capabilities. The SBIR.gov website aggregates solicitations from all participating agencies.
Step 2: Develop Your Proposal
SBIR proposals require a technical approach, work plan, budget, team qualifications, and commercialization plan. Proposals are evaluated on innovation, technical merit, team capability, and commercial potential.
Step 3: Submit Through Agency Portal
Each agency has its own submission system. DOD uses DSIP, NIH uses eRA Commons, NSF uses Research.gov, and other agencies have their own portals. Register early — account setup can take weeks.
Texas SBIR Support Resources
- SBDC Network: Texas SBDCs provide free SBIR proposal assistance and workshops.
- University Technology Offices: UT Austin, Texas A&M, Rice, and other universities can help identify STTR partnership opportunities.
- SBIR/STTR Conferences: National and regional conferences connect applicants with agency program managers.
