What Is SBIR? How to Apply.

The Small Business Innovation Research (SBIR) program represents one of America’s best-kept secrets in the world of entrepreneurship and innovation funding. If you’re a small business owner with big ideas, the SBIR program could be your ticket to turning groundbreaking concepts into commercial realities—without giving up equity or taking on debt.

This competitive federal grant program isn’t just another government initiative; it’s America’s largest seed fund, providing over $4 billion annually to small businesses across the country. Whether you’re developing cutting-edge technology or exploring scientific frontiers, understanding the SBIR program could be the difference between your innovation sitting on a shelf or changing the world.

The History and Purpose of SBIR

The SBIR program was born in 1982 when President Ronald Reagan signed the Small Business Innovation Development Act into law. This groundbreaking legislation, championed by Roland Tibbetts (often called the “Father of the SBIR Program”), created a structured pathway for small businesses to participate in federal research and development.

Before SBIR, federal R&D dollars primarily flowed to large corporations, universities, and government labs. Small businesses—despite their proven track record of innovation efficiency—were largely left out of the equation. The SBIR program changed that dynamic by mandating that federal agencies with substantial R&D budgets set aside a percentage of those funds specifically for small businesses.

The genius of the SBIR program lies in its dual purpose: it helps federal agencies solve their most pressing technical challenges while simultaneously supporting American entrepreneurship. As Matthew Weinberg, former senior advisor in the Small Business Administration’s Office of Investment and Innovation, puts it, the SBIR program represents the “crossroads of all paths of innovation,” showing the public sector represented and reflected in innovation and science.

Over the past four decades, the program has evolved and grown, with its funding percentage increasing from an initial 0.2% to over 3.2% of federal R&D budgets today. What began as an experiment in federal innovation policy has become one of the most successful government programs for stimulating technological advancement and economic growth.

How SBIR Works: The Basics

At its core, the SBIR program follows a structured, three-phase approach designed to reduce risk while maximizing the potential for successful commercialization.

Phase I: Concept Development

The journey begins with Phase I, representing the concept development stage. If you qualify, you’re eligible for over $150,000 of non-dilutive capital—the average is $158,000—over the course of six months.

According to the SBIR program, the goal of Phase I is “to establish the technical merit, feasibility, and commercial potential of the proposed R/R&D efforts and to determine the quality of performance of the small business awardee organization prior to providing further Federal support in Phase II.” In plain English, though, this is the period where your business works on the proposal concept, using that federal funding to figure out whether your proposal is actually workable in practice.

Phase II: Prototype Development

If you’ve proven that your proposal is a workable concept that can benefit the government—and everyone else!—if it gets developed, here comes Phase II: the biggest round of funding offered by the SBIR program.

You’ll have to apply again, but this time around will be much simpler: your Phase I award should come with a timeline for your Phase II application, usually between eight and 20 months later. Phase II awards are given based on the results of your Phase I tests and research and are intended to fund the creation of an actual, workable prototype. In other words, Phase II is when you move from idea to product.

This stage of the program lasts for around two years and you can get over $1 million in federal funding. The average financing is roughly $920,000 overall, but it depends on your proposal as well as your federal agency.

Phase III: Commercialization

The SBIR program’s Phase III actually comes with zero dollars in funding because the point of Phase III isn’t to keep giving you government money as you research and develop your original proposal—it’s the SBA’s goal to commercialize you.

Instead of getting a government grant through the SBIR program, you’ll either procure non-SBIR program federal funds through a contract with your agency or find private capital to keep financing your business. Basically, with a Phase III award, you’re very much in line to snag a substantial investment from beyond the SBIR program.

Those funds might come from a traditional source of capital, like an investment bank or private equity firm, or you might get a contract to work with the government. For example, the Department of Defense might want to extend a contract so you can keep working together, refining your technology. (But don’t worry—the small business owners will keep their intellectual property rights over their developments. That’s an important part of the SBIR program.)

The Federal Agencies Behind SBIR

Currently, eleven federal agencies participate in the SBIR program, each with their own distinct missions, priorities, and areas of focus:

  1. Department of Defense (DoD): The largest SBIR program, offering opportunities across the Army, Navy, Air Force, DARPA, and more.
  2. Department of Health and Human Services (HHS): Primarily through the National Institutes of Health (NIH), focusing on biomedical and healthcare innovations.
  3. Department of Energy (DOE): Supporting energy efficiency, renewable energy, and advanced energy technologies.
  4. National Science Foundation (NSF): Funding a broad spectrum of scientific and engineering research without specific agency needs.
  5. National Aeronautics and Space Administration (NASA): Seeking solutions for space exploration and aeronautics challenges.
  6. Department of Agriculture (USDA): Supporting innovations in agriculture, food safety, rural development, and more.
  7. Department of Commerce (DOC): Through the National Oceanic and Atmospheric Administration (NOAA) and National Institute of Standards and Technology (NIST).
  8. Department of Education (ED): Focusing on educational technologies and tools.
  9. Department of Transportation (DOT): Supporting innovations in transportation safety, efficiency, and infrastructure.
  10. Department of Homeland Security (DHS): Focusing on security technologies and systems.
  11. Environmental Protection Agency (EPA): Supporting innovations in environmental protection and sustainability.

Each agency runs its SBIR program independently, with unique solicitation topics, evaluation criteria, and application processes. This decentralized approach means that understanding the specific needs and culture of your target agency can significantly improve your chances of success.

SBIR vs. STTR: Understanding the Differences

While exploring SBIR, you’ll likely encounter its sister program: Small Business Technology Transfer (STTR). Though similar in structure, STTR has a key distinction that sets it apart.

The STTR program requires small businesses to formally collaborate with a research institution (typically a university or federal laboratory) throughout the project. This mandatory research partnership aims to bridge the gap between fundamental science in research institutions and the commercialization capabilities of small businesses.

In contrast, the SBIR program allows—but doesn’t require—partnerships with research institutions. This flexibility lets SBIR businesses choose their approach based on their internal capabilities and specific project needs.

Currently, five federal agencies participate in the STTR program: DoD, HHS, DOE, NASA, and NSF. With a smaller total budget than SBIR, STTR awards are generally more competitive but offer an excellent pathway for businesses looking to commercialize academic research.

The decision between SBIR and STTR often depends on your existing relationships with research institutions and your internal research capabilities. Many successful companies have strategically leveraged both programs to advance different aspects of their technology development.

The SBIR Application Process

When one of those 11 federal agencies realizes that it needs a scientific development or new piece of technology, it writes up an RFP—or a request for proposal.

These RFPs only last for a certain amount of months before expiring. They’ll include information on:

  • The department that would be funding you
  • The participating organizations
  • The relevant dates and deadlines
  • What sorts of scientific innovations are being looked for
  • What sorts of businesses are eligible
  • What you’ll need to apply

In short, an RFP will have all the information you need to understand who you’re applying to, when you’ll need to apply by, and what developments you’ll apply for.

Step 1: Find the Right SBIR Program RFP

The first step for you is finding the right request for proposal.

After all, your small business might be close to making a technological breakthrough or scientific discovery, but chances are high that it’s a pretty specific innovation. If the Department of Defense might give you funding, then the Department of Education probably wouldn’t.

Check the SBIR program’s RFP portal (make sure “SBIR” is selected in the filters on the left!) and narrow your search with relevant keywords or agencies. Check out the RFPs that seem plausible for your business and click the “official link for this solicitation” to see the full request.

Alternatively, you can go directly to each agency’s SBIR program page and peruse their specific requests. (Here’s NASA’s SBIR page, for example.)

Step 2: Submit Your Proposal

This step is pretty straightforward: gather all the materials indicated on the RFP and submit!

When writing your proposal, make sure to follow the guidelines outlined by the RFP you’re submitting to, whether that means page limits and margin sizes, cover sheets, possible budgets, or anything else. In general, your proposal should describe your innovation, its relevance, and importance, show that it’s plausible, and propose a strategy for development and commercialization. (On average, SBIR program proposals take six to eight weeks to complete.)

Here are some additional documents or reference IDs you might need to attach:

  • Letter of intent
  • Business plan
  • Cost proposal
  • Technical proposal
  • SBA company registry
  • SBIR Application Certification for certain kinds of businesses
  • Dun and Bradstreet Data Universal Numbering System (DUNS)
  • System for Award Management (SAM)

And pay attention to the format of your proposal and attachments—some agencies have strict requirements regarding the file type and name of your application.

Step 3: Evaluation

Your proposal will get evaluated by the relevant peer reviewers working for the agency you’ve applied to. These reviewers might be external, internal, or a mix of both. Depending on your timing in the application cycle and the agency you’ve applied to, hearing back about your proposal could take anywhere from three to six months.

The SBIR program agency will evaluate your proposal based on three main criteria:

  1. How well your proposal tackles the issue of the RFP.
  2. The skills of you and your team.
  3. Whether your innovation has the potential to commercialize.

SBIR Eligibility: Do You Qualify?

The first question you should ask yourself is whether you have the type of business that can apply for the SBIR program.

According to their guidelines, you have to “qualify as a Small Business Concern (SBC) as defined by SBA regulations at 13 C.F.R. §§ 701-705.”

Here’s what that actually means:

1. Your business is for-profit.

Plus, you must be located in the U.S., operate primarily in the U.S., or give back to the U.S. economy a good amount through taxes and purchases. Pretty simple.

2. You fit a certain kind of legal entity type.

Those business entity types are: sole proprietorship, partnership, limited liability company, corporation, joint venture, association, trust, or cooperative.

3. Your business is at least 51% directly owned and controlled by…

Citizens or permanent resident aliens of the U.S., other small businesses that are themselves at least 51% owned by the same, or some combination of the two.

In other words, you’ve got to be mostly owned by citizens or permanent residents—either directly or indirectly.

4. You’ve got 500 or fewer employees.

Including affiliates.

Finally, the SBIR program does allow businesses owned by venture capital firms, hedge funds, and private equity funds—as long as the majority of those owners themselves qualify as small business concerns.

Success Stories and Case Studies

The true measure of the SBIR program’s impact can be found in the thousands of companies that have leveraged this funding to create groundbreaking innovations. Here are just a few standout success stories:

Qualcomm

Before becoming a telecommunications giant, Qualcomm received SBIR funding from DARPA in the 1980s to develop satellite communication technology. This early support helped the company develop its core technologies that eventually led to revolutionary advances in mobile communications. Today, Qualcomm is a multi-billion dollar company whose technology powers billions of smartphones worldwide.

iRobot

The maker of the popular Roomba vacuum cleaner started with SBIR grants from the Department of Defense to develop robots for military applications. The company successfully transitioned this technology to consumer products, creating a new market for home robotics and changing how millions of people clean their homes.

Google

While Google itself wasn’t directly funded through SBIR, its origins can be traced to a similar government-funded research initiative. In 1996, the National Science Foundation needed a way to search through the fast-growing World Wide Web, so they submitted a request for proposal to the public that encouraged entrepreneurs working on this problem to apply for funding. The NSF gave funding to the Stanford Digital Library Project to “develop the enabling technologies for a single, integrated and universal digital library.” Two Stanford Ph.D. students joined the Project for their dissertation and invented something that you probably use every day, that product was Google.

The government agency knew that it needed a smart way to search the internet, so it sent out a request—and when Stanford’s Digital Library Project submitted a proposal to solve the problem, they got funding to keep working. While Google owes its origin to the National Science Foundation, not the SBIR, the process is the same: a government agency submits a request for technology it needs, and small businesses rise to the challenge.

Illumina

This biotech company received SBIR funding from the National Institutes of Health to develop DNA sequencing technology. Today, Illumina is a leader in genomics technology, and its sequencing platforms have dramatically reduced the cost of DNA sequencing, enabling countless medical breakthroughs and personalized medicine approaches.

These success stories represent just the tip of the iceberg. The SBIR program has helped create around 700 companies go public and led to the creation of over 70,000 patents (roughly a quarter of all utility patents granted by the U.S.). The technologies developed through this program touch virtually every aspect of modern life, from healthcare and communications to energy and defense.

Strategic Considerations for Applicants

Beyond the mechanics of eligibility and application, several strategic considerations can dramatically improve your chances of SBIR success.

Intellectual Property Strategy

SBIR awards come with unique intellectual property provisions that are generally more favorable than traditional government contracts. Under the SBIR program, small businesses retain the rights to their innovations, with the government receiving a non-exclusive license for government use.

This means you should think carefully about your IP strategy before, during, and after your SBIR project. Consider:

  • Filing provisional patents before submitting your proposal
  • Developing a clear strategy for protecting trade secrets during the project
  • Planning for international IP protection if your innovation has global potential

A well-thought-out IP strategy not only protects your innovation but also significantly enhances your commercialization potential.

Building the Right Team

SBIR reviewers place considerable emphasis on the capabilities of your team. While technical expertise is crucial, successful SBIR companies typically demonstrate a balanced mix of scientific, engineering, and business capabilities.

Consider including:

  • Technical leads with relevant domain expertise
  • Business development professionals who understand your target market
  • Industry advisors who can provide credibility and connections
  • Research partners from universities or national labs (especially important for STTR)

If your current team has gaps, consider using consultants or advisory board members to strengthen your proposal.

Commercialization Planning

While the technical innovation is at the heart of SBIR, the program’s ultimate goal is commercialization. Every proposal should include a robust commercialization plan that addresses:

  • Market size and potential
  • Competitive landscape
  • Go-to-market strategy
  • Potential partners and customers
  • Scale-up and manufacturing considerations
  • Regulatory pathways (if applicable)

The most successful SBIR applicants begin customer discovery and market validation during Phase I, demonstrating real commercial traction by Phase II.

Beyond the Grant: Additional Resources

The SBIR program offers more than just direct funding. A range of supplementary programs and resources can amplify the impact of your SBIR award.

Technical Assistance Programs

Most SBIR agencies offer technical assistance programs that provide specialized support beyond the core funding. For example:

  • NIH’s Technical Assistance Program: Offers up to $6,500 in business consulting services for Phase I awardees
  • NSF’s I-Corps Program: Provides entrepreneurial education and customer discovery support
  • DoD’s Transition Assistance Program: Helps companies prepare for Phase III and commercialization

These programs often include access to expert consultants, market research resources, and specialized training that would be prohibitively expensive for early-stage companies to access otherwise.

State-Level Matching Programs

Many states have recognized the value of SBIR and created matching fund programs to enhance federal dollars. States like Massachusetts, Kentucky, and Hawaii offer significant matching funds (sometimes up to 100% of the federal award) to SBIR recipients located in their state.

These matching programs can effectively double your R&D budget without additional equity dilution. Some states also offer proposal development assistance, including grant writing support and review services.

Networking and Mentorship

The SBIR ecosystem includes numerous conferences, meetups, and mentorship opportunities. The National SBIR Conference, held annually, brings together program managers from all participating agencies along with successful SBIR entrepreneurs and investors interested in SBIR technologies.

Agency-specific events, like the HHS SBIR/STTR Conference or the DoD Beyond Phase II Conference, provide targeted networking opportunities with program managers and potential Phase III partners.

As we look to the future, several trends are shaping the evolution of the SBIR program:

Increased Focus on Commercialization

Recent reauthorizations of the SBIR program have placed greater emphasis on commercialization outcomes. Agencies are increasingly tracking the commercial success of their awardees and focusing resources on companies with clear commercialization potential.

Expanded Diversity Initiatives

The SBIR program has a number of initiatives to help increase the diversity of its small business applicants, like working with universities and traveling on a tour bus around the country to reach underserved communities.

This focus on diversity isn’t just about fairness—it’s about unlocking innovation potential. According to Weinberg, “The government’s ultimate goal isn’t to make a profit. It’s to make sure these resources are invested equitably. It’s not our belief that innovation should only occur in a few geographical areas and be relegated to white males.”

Around 23% of the SBIR program’s funding has gone to exclusively women-owned or minority-owned businesses, including EpiBone (founded by Nina Tandon) and Zyrobotics (by Ayana Howard). While this is progress, there’s still more work to be done, as approximately 30% of privately held firms are owned by women.

Integration with Other Innovation Ecosystems

The lines between SBIR funding and other innovation support systems are increasingly blurring. Many accelerators now specialize in SBIR-funded companies, and venture capital firms are becoming more comfortable investing alongside or after SBIR funding.

This integration creates new opportunities for SBIR companies to leverage multiple funding sources and support systems simultaneously.

Getting Started: Next Steps

If you’re considering pursuing SBIR funding, here are some concrete steps to get started:

1. Assess Your Eligibility

Before investing significant time in proposal development, verify that your business meets all eligibility requirements and that your innovation aligns with federal R&D priorities.

2. Identify Target Agencies

Research which agencies fund innovations in your domain. The SBIR.gov website provides searchable databases of past awards that can help you identify the most relevant agencies for your technology.

3. Track Solicitation Schedules

Each agency follows its own solicitation schedule. Some, like DoD, issue multiple solicitations per year, while others have annual cycles. Mark these dates on your calendar and begin preparation well in advance.

4. Build Agency Relationships

Many successful SBIR applicants initiate relationships with program managers before submitting proposals. While program managers cannot provide specific proposal guidance, they can clarify agency priorities and help you understand if your innovation aligns with their interests.

5. Leverage Free Resources

The SBA offers numerous free resources for SBIR applicants, including:

  • Agency-specific webinars
  • Proposal writing tips
  • Sample successful proposals
  • State-level SBIR support organizations

These resources can significantly improve your proposal quality and increase your chances of success.

The Bottom Line

The SBIR program represents a unique opportunity in the American innovation landscape—a chance to access substantial non-dilutive funding for high-risk, high-reward R&D that might otherwise never leave the drawing board.

As Weinberg puts it, “The government is committed to advancing innovation,” and the SBIR program is “a special piece of the government that’s really, deeply responsible for thinking about how to make the future better, brighter, and safer for future generations.”

Whether you’re a small business owner looking to apply for funding, a potential entrepreneur on the search for inspiration, or an everyday citizen benefitting from the SBIR program’s many life-changing breakthroughs, you have the Small Business Administration—and the small businesses of the United States—to thank.

By bridging the gap between early-stage research and commercial application, the SBIR program doesn’t just fund individual companies—it fuels the engine of American innovation itself.
