The Small Business Technology Transfer (STTR) program is a U.S. federal funding program that helps small businesses develop new technologies through formal research partnerships with universities, nonprofit research organizations, or Federally Funded Research and Development Centers (FFRDCs).
STTR is part of America’s Seed Fund, coordinated by the U.S. Small Business Administration (SBA). The funding is designed for research and development projects that have the potential to become commercial products or services. STTR funding is non-dilutive, meaning the federal government does not take equity in the business for the award. SBIR
What Are STTR Grants?
STTR stands for Small Business Technology Transfer.
The program is designed to connect American small businesses with nonprofit research institutions to develop and commercialize innovative technologies. Unlike an ordinary small-business grant, STTR funding is focused on research and development (R&D) rather than general business expenses.
A key requirement is that the small business must formally collaborate with an eligible research institution during the STTR project. SBIR
The goal is to move promising research from the laboratory toward real-world commercial products and services.
How Much Money Can a Small Business Get?
STTR funding is divided into phases.
STTR Phase I
Phase I is designed to determine whether the proposed technology is technically feasible and has commercial potential.
According to the federal SBIR/STTR program information, Phase I awards normally do not exceed $150,000 in total costs for one year. However, individual agencies can establish their own award amounts and requirements. SBIR
The current America’s Seed Fund application information also shows that award amounts can vary by agency and opportunity, so applicants should always check the specific solicitation before preparing a proposal. SBIR
STTR Phase II
Phase II continues the R&D work started during Phase I.
Federal STTR guidance says Phase II awards normally do not exceed $1 million in total costs for two years. Only businesses that received a Phase I award are generally eligible for Phase II. SBIR
The actual funding amount depends on the federal agency and the specific funding opportunity.
STTR Phase III
Phase III is the commercialization stage.
STTR itself does not provide Phase III funding. Instead, the business can pursue private investment, commercial sales, or other federal contracts and funding that support commercialization. SBIR
Who Is Eligible for STTR Grants?
STTR is not available to every small business.
Generally, an eligible applicant must be a U.S.-based, for-profit small business that meets the federal program’s ownership, control, and size requirements. The SBIR/STTR eligibility guidance states that the business must meet the applicable requirements for a small business concern and generally have fewer than 500 employees. SBIR
A business also needs to meet the specific requirements in the agency solicitation.
For example, the federal program requires an STTR awardee to qualify as an eligible small business at the time of award. SBIR
Do You Need a University or Research Partner?
Yes.
This is one of the biggest differences between STTR and SBIR.
An STTR project requires a formal partnership between the small business and an eligible research institution.
Eligible research institutions include:
- Nonprofit colleges and universities
- Domestic nonprofit scientific or research organizations
- Federally Funded Research and Development Centers (FFRDCs)
The research institution must be located in the United States and meet the federal program’s requirements. SBIR
This means that if your business wants to apply for STTR, you should identify an appropriate research partner before submitting the proposal.
How Is the STTR Work Divided?
STTR has specific work-performance requirements.
The small business must perform at least 40% of the research and development work, while the partnering research institution must perform at least 30%. The remaining work can be performed according to the applicable program rules. SBIR
The small business also maintains overall responsibility for managing the project.
This requirement makes STTR different from simply hiring a university as a consultant. The federal program is intended to create a genuine research partnership.
What Agencies Offer STTR Funding?
Several federal agencies participate in the STTR program.
The SBIR program’s official FAQ currently identifies these six agencies as participating in STTR:
- U.S. Department of Agriculture (USDA)
- Department of Defense (DOD)
- Department of Energy (DOE)
- Department of Health and Human Services (HHS)
- National Aeronautics and Space Administration (NASA)
- National Science Foundation (NSF)
Each agency has its own research priorities, topics, application requirements, deadlines, and award structures. SBIR
Because of this, a business should not simply search for “STTR grant” and apply to the first opportunity it finds. The proposed technology needs to fit the agency’s research needs.
What Types of Businesses Can Use STTR Funding?
STTR is primarily intended for businesses developing innovative technologies and conducting research that can address federal agency needs.
Potential areas can include technologies related to:
Healthcare and biotechnology: Medical devices, diagnostics, biotechnology, health technologies, and other research areas supported by HHS and NIH.
Agriculture: Agricultural technology, food technology, environmental technology, and other areas supported by USDA.
Energy: Clean energy, advanced materials, energy systems, and related technologies.
Defense: Technologies addressing research and development needs identified by the Department of Defense.
Space: Aerospace, space technology, and other technologies that meet NASA research priorities.
Science and engineering: Innovative technologies across many scientific and technical fields supported by NSF.
The exact subjects change according to agency solicitations, so applicants should review current topics rather than assume that every technology qualifies.
STTR Grants Are Not General Business Grants
This is an important point.
STTR funding is not normally intended to pay for ordinary business expenses such as general marketing, office rent, routine payroll, or starting a conventional retail business.
The program supports research and development connected to a federal agency’s stated needs.
For example, a company developing a new medical diagnostic device could potentially pursue STTR funding if its research fits an eligible agency topic. A traditional restaurant looking for money to purchase kitchen equipment would generally not be an STTR candidate.
How to Find Current STTR Opportunities
The official SBIR/STTR website is the best starting point for finding federal opportunities.
Official SBIR/STTR Funding Opportunities
The federal site allows businesses to explore funding opportunities and agency topics. The program recommends checking the agency’s official solicitation because information displayed on the SBIR website may not always be the latest version of an agency’s solicitation. SBIR
You can also search federal grant opportunities through:
For example, a current USDA SBIR/STTR Phase II opportunity listed for FY2026 has a November 17, 2026 closing date and provides up to $650,000 under that particular opportunity. This demonstrates why applicants should check the individual solicitation rather than rely on a general STTR funding amount. Simpler Grants
How to Apply for an STTR Grant
The application process starts with identifying a technology that matches a federal research need.
1. Develop Your Technology Idea
Your project should involve genuine research and development.
You should be able to explain:
- What problem you are solving
- What technology you are developing
- Why the technology is innovative
- What research is needed
- Why the project matters
- How the technology could eventually become a commercial product or service
2. Find a Research Institution
Next, find an eligible research institution that can work with your company.
This could be a university, nonprofit research organization, or eligible FFRDC.
The partnership should be established before submitting the STTR proposal.
3. Find a Matching Federal Topic
Search the official STTR opportunities for a topic that matches your technology.
Do not try to force your idea into an unrelated topic. Federal agencies evaluate proposals according to their research priorities and requirements.
4. Register Your Business
Your company needs the required federal registrations.
The SBIR/STTR program states that a business needs a Unique Entity ID (UEI) from SAM.gov to receive an SBIR/STTR award. SBIR
5. Read the Complete Solicitation
Every opportunity can have different requirements.
Before applying, check:
- Eligibility
- Research topic
- Award amount
- Project period
- Required forms
- Proposal requirements
- Research-partner requirements
- Deadlines
- Commercialization requirements
6. Prepare the Proposal
The proposal should clearly explain both the technical research and the potential commercial value.
A strong proposal should show why the technology is innovative, how the research will be performed, why the proposed team is qualified, and how the project can eventually lead to commercialization.
7. Submit Through the Required Federal System
The application system depends on the agency and specific opportunity.
Always follow the submission instructions in the current solicitation.
STTR vs. SBIR
STTR and SBIR are closely related, but there is an important difference.
| Feature | STTR | SBIR |
|---|---|---|
| Small business required | Yes | Yes |
| For-profit business | Generally required | Generally required |
| Research and development | Yes | Yes |
| Formal research institution partnership | Required | Not generally required |
| Small business minimum work | 40% | Different requirements |
| Research institution minimum work | 30% | No STTR-style requirement |
| Phase I | Yes | Yes |
| Phase II | Yes | Yes |
| Phase III funding | No STTR funding | No SBIR funding |
The official SBIR program identifies the formal research-institution partnership as the primary distinction between STTR and SBIR. SBIR
Is STTR Funding a Loan?
No.
STTR awards are federal research funding rather than conventional business loans.
America’s Seed Fund describes SBIR/STTR funding as non-dilutive funding, and the government does not take equity or ownership of the company simply because it receives this funding. SBIR
However, an STTR award comes with significant rules and reporting requirements. It is not free money for unrestricted business spending.
Do You Have to Repay an STTR Grant?
Generally, an STTR award is not structured like a loan that the business repays.
The funding is awarded to conduct approved research and development under the applicable federal agreement.
However, receiving an award does not mean the company can use the money however it wants. The business must follow the terms of the award, federal requirements, and the specific agency’s rules.
Can a Startup Apply for STTR?
Yes, a startup can potentially qualify if it meets the federal eligibility requirements.
In fact, America’s Seed Fund is designed to help innovative small businesses develop technologies and move them toward commercialization. SBIR
But being a startup alone is not enough. The company must meet the ownership, size, location, organizational, registration, and other requirements.
Most importantly, an STTR applicant needs an eligible research institution partner.
Where Can You Get Help With an STTR Application?
The official SBIR/STTR program provides resources for entrepreneurs and points applicants toward organizations that can help with proposal preparation, registrations, commercialization, and other parts of the process. SBIR

Bottom Line
STTR grants can be a strong funding option for U.S. small businesses developing new technology, especially when the project requires collaboration with a university or nonprofit research organization.
The most important thing to remember is that STTR is not a general small-business grant. Your company must meet federal eligibility rules, have an eligible research partner, develop technology that fits an agency’s research priorities, and submit a competitive R&D proposal.
Because funding amounts, topics, deadlines, and requirements can change by agency and fiscal year, always verify the current solicitation before applying.
