If your small business or startup is seeking funding to drive innovation or bring your R&D projects to market, you’ve likely come across SBIR and STTR programs. These federal programs offer crucial non-dilutive funding to small businesses, but applying for them can feel daunting.  

This guide breaks down the eligibility criteria, application requirements, and key differences between SBIR and STTR to help you navigate the process with confidence. 

What Are SBIR and STTR Programs? 

SBIR (Small Business Innovation Research) and STTR (Small Business Technology Transfer) programs are competitive government grant initiatives designed to stimulate technological innovation and promote commercialization of research and development (R&D). Unlike venture capital funding, these grants don’t require you to give up equity, making them an attractive option for small businesses.  

Why Are These Programs Valuable? 

These grants not only provide financial support but also validate your business and technology in the eyes of future investors and customers. For startups looking to scale or small businesses wanting to innovate, SBIR and STTR funding can serve as invaluable steppingstones. 

SBIR/STTR Application Requirements

Specific Program Requirements

If your business involves a nonprofit Research Institution (RI), you may best qualify for STTR rather than SBIR.

Meeting these eligibility requirements is non-negotiable. Ensure all documentation is accurate and complete to avoid delays in your application. 

SBIR vs. STTR: Understanding the Key Differences  

  1. Collaboration Requirements

SBIR focuses largely on small businesses and allows maximum applicant flexibility. While subcontractors (including Research Institutions) can be involved, they are not mandatory.

STTR, however, requires small businesses to partner with nonprofit Research Institutions like universities. 

  1. Work Allocation

• Under SBIR Phase I, the small business must perform two-thirds of the work, with subcontractors allowed to take on one-third.

• With STTR Phase I, small businesses handle 40% of the work while Research Institutions must conduct a minimum of 30%.

  1. Intellectual Property (IP) Transfer

STTR programs require that IP developed at the partnering Research Institution is transferred to the small business, which can sometimes lead to complex agreements.

When to choose SBIR

SBIR may be a better fit if:

You want subcontractor flexibility, not exclusive to universities or government labs.

Completing the Necessary Registrations

Before submitting your proposal, certain registrations are mandatory, and some take up to 8 weeks to process. Starting early is essential:

  1. System for Award Management (SAM)

• Register at sam.gov to obtain a Unique Entity Identifier (UEI) and a CAGE code.

• Registration can take 4-6+ weeks and requires annual renewal.

  1. SBA Company Registry

• Register your business on SBIR.gov after activating your SAM account. 

  1. Additional Agency Registrations

Depending on the agency, you may need account setups for: 

• eRA Commons (Dependent upon agency) 

Grants.gov, DSIP, or others, based on the funding source. 

Failure to complete these registrations will disqualify your application, so begin these steps as soon as possible.
