What Are SBIR and STTR?
The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs fund R&D at small businesses to develop innovative technologies.
Program basics:
- Competitive awards to small businesses
- Fund high-risk, high-reward R&D
- Goal: commercialization of innovations
- No equity dilution (non-dilutive funding)
SBIR vs STTR:
SBIR:
- Small business performs primary research
- May partner with others
- No required research institution
STTR:
- Requires research institution partnership
- University, federal lab, or nonprofit research org
- Minimum 30% by small business, 40% by research partner
Participating agencies (11 for SBIR, 5 for STTR):
- DoD, NIH, NASA, DOE, NSF
- USDA, EPA, DHS, DOT, ED, HHS
Program Phases
Phase I — Feasibility:
- Prove scientific/technical feasibility
- 6-12 months duration
- Funding: $50,000-$275,000 (varies by agency)
- Foundation for Phase II
Phase II — Development:
- Full R&D of technology
- Prototype development
- 24 months typical duration
- Funding: $500,000-$1.7 million
- Requires successful Phase I
Phase III — Commercialization:
- No SBIR funding (uses other sources)
- Government contracts for developed product
- Commercial sales
- Private investment
Direct to Phase II:
- Some agencies allow skipping Phase I
- Must demonstrate equivalent feasibility
- For technologies with proven basis
Sequential Phase II:
- Multiple Phase II awards on same topic
- Agency-specific rules
Eligibility Requirements
Small business eligibility:
- For-profit U.S. business
- 500 or fewer employees (including affiliates)
- More than 50% owned by U.S. citizens or permanent residents
- OR more than 50% owned by other small businesses
Principal investigator (PI):
SBIR:
- PI must be primarily employed by small business
- More than 50% of time
- During project performance
STTR:
- PI can be from either partner
- Small business or research institution
- More flexibility
Work location:
- SBIR: At least 2/3 (Phase I) or 1/2 (Phase II) by small business
- STTR: 40% minimum each for small business and research partner
VC/private equity considerations:
- Majority VC-owned may still qualify
- Must still meet small business size
- Affiliation rules apply

Commercialization Strategy
Why commercialization matters:
- Primary program goal
- Affects Phase II selection
- Commercialization metrics tracked
- Required for program success
Commercialization pathways:
- Government customer — Phase III contracts
- Commercial markets — Private sales
- Licensing — Technology licensing
- Acquisition — Company sale
Phase III:
- Follow-on government contracts
- Uses non-SBIR funds
- Sole source possible
- Data rights protection
Building commercial traction:
- Customer discovery during Phase I
- Letters of interest
- Partnerships
- Private investment alongside SBIR
Data rights:
- Strong SBIR data rights protection
- Up to 20 years protection
- Protects commercial potential

Frequently Asked Questions
Q:What is the difference between SBIR and STTR?
SBIR is for small businesses doing their own R&D. STTR requires partnership with a research institution (university, federal lab, nonprofit). STTR ensures technology transfer from research to commercialization.
Q:How much funding can I get?
Phase I typically ranges from $50,000-$275,000 depending on agency. Phase II ranges from $500,000-$1.7 million. Some agencies allow larger awards. Total funding varies significantly by agency.
Q:Is SBIR a grant or contract?
Both exist. Some agencies (NIH, NSF) primarily use grants. Others (DoD) use contracts. The legal structure differs, but both provide R&D funding. Check each agency's approach.
Q:Can I apply to multiple agencies?
Yes, but not for the same work. Different agencies may be appropriate for different technologies or applications. Don't submit duplicate proposals.
Q:Do I need a prototype for Phase I?
No. Phase I is to prove feasibility. You're demonstrating that your concept can work. Prototype development typically occurs in Phase II.
Q:What happens to my intellectual property?
SBIR provides strong IP protections. You retain ownership of inventions. Data rights are protected for up to 20 years. This is a major advantage of SBIR funding.
Q:Can VC-backed companies apply for SBIR?
Yes, in most cases. Even majority VC-owned companies may be eligible if they still meet small business size standards and other requirements. Affiliation rules apply.
Q:What is the success rate for SBIR proposals?
Varies by agency and topic, typically 15-25% for Phase I. Competition is significant. Strong proposals, good fit with agency needs, and persistence are key.
