SBIR/STTR

The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are competitive federal grant programs designed to spur economic development and stimulate technological innovation and commercialization through small businesses, including faculty startups. For both grant programs, the application is always submitted by the small business, not by the University. 


SBIR Program Overview

The SBIR program was established to engage small businesses in federal research and development with potential for commercialization. Key features include: 

  • Eligibility: US-owned and operated small businesses with fewer than 500 employees 
  • Funding structure:  
    • Phase I: Feasibility studies (typically $50,000-$250,000 for 6 months) 
    • Phase II: R&D work (typically $750,000-$1,700,000 for 2 years) 
    • Phase III: Commercialization (no SBIR funds, but potential for non-SBIR government/private funding) 
  • Participating agencies: 11 federal agencies with R&D budgets over $100 million (including DOD, HHS/NIH, NSF, DOE, NASA) 

STTR Program Overview

The STTR program is similar to SBIR, but requires small businesses to formally collaborate with a research institution. Key features include: 

  • Eligibility: Same as SBIR, plus formal collaboration with a nonprofit research institution
  • Research institution partnership: Requires the small business to partner with a nonprofit research institution (university, federal laboratory, etc.) 
  • Funding structure: Similar to SBIR with Phase I, II, and III 
  • Participating agencies: Five federal agencies (DOD, HHS/NIH, NSF, DOE, NASA) 
  • Work allocation: Small business must perform at least 40% of the work; research institution must perform at least 30% 

SBIR & STTR: What’s Different?

  • Research institution partnership: Required for STTR, optional for SBIR
  • Principal investigator location: For STTR, some federal agencies permit the PI to be primarily employed by either the small business or research institution; for SBIR, the PI must be primarily employed by the small business
  • Number of participating agencies: 11 for SBIR, 5 for STTR 

Benefits of These Programs

  • Non-dilutive funding (no equity given up)
  • Retention of intellectual property rights
  • Validation of technology through federal support
  • Potential for follow-on funding and contracts
  • Technical and business assistance provided by many agencies
