PROGRAM BASICS

  1. What are the SBIR and STTR programs? What are the differences between the two programs, and which program is more appropriate for my project?

    The Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs are highly competitive programs that encourage domestic small businesses to engage in Federal Research/Research and Development (R/R&D) with the potential for commercialization. Through a competitive awards-based program, SBIR and STTR enable small businesses to explore their technological potential and provide the incentive to profit from its commercialization. By including qualified small businesses in the nation's R&D arena, high-tech innovation is stimulated, and the United States gains entrepreneurial spirit as it meets its specific research and development needs.

    Both SBIR and STTR Programs have identical philosophies, review criteria, review processes, and award dollar amounts. The two programs also have similar success rates.

    STTR's most important role is to bridge the gap between performance of basic science and commercialization of resulting innovations. Central to the STTR program is the partnership between small businesses and nonprofit research institutions. The STTR program requires the small business to formally collaborate with a research institution. As a result, an STTR proposal must include a Cooperative Research Agreement (CRA) between the small business and the research institution or a letter indicating that a CRA will be forthcoming upon notification of an award recommendation.

    We recommend that potential proposers wait until invited to submit a full proposal to choose between the SBIR and STTR programs. The budget requirements of the two programs can be used to determine which is more appropriate for a given project. For an STTR submission, a minimum of 40% of the research, as measured by the budget, must be performed by the small business concern and a minimum of 30% of the research, as measured by the budget, must be performed by the not-for-profit research institution, with the balance permitted to be allocated to either of these, or to other subawards or consultants. Converting submissions between SBIR and STTR, is possible at many agencies.

  2. What are the funding priorities for the SBIR/STTR programs?

    The SBIR/STTR programs are intended to support scientific and engineering excellence and technological innovation that is moving from the lab to the market. By investing federal research and development funds into startups and small businesses, the Federal government hopes to build a strong national economy and stimulate the creation of novel products, services, and solutions in the private sector; strengthen the role of small business in meeting federal research and development needs; increase the commercial application of federally supported research results; and develop and increase the US workforce, especially by fostering and encouraging participation by socially and economically disadvantaged and women-owned small businesses.

    The SBIR/ STTR program solicit proposals based on groundbreaking scientific discoveries or significant engineering breakthroughs from small businesses consistent with each agency's mission.

  3. What is innovative research and how do I gauge whether my research is a good fit?

    The NSF SBIR/STTR programs fund the research and development (R&D) of deep technologies, which are based on discoveries in fundamental science and engineering. Proposals that are a good fit for the programs generally feature most or all of the below aspects:

    • the application of creative, original, and potentially transformative concepts to systematically study, create, adapt, or manipulate the structure and behavior of the natural or man-made worlds;

    • the use of the scientific method to propose well-reasoned, well-organized activities based on sound theory, computation, measurement, observation, experiment, or modeling;

    • the demonstration of a well-qualified individual, team, or organization ready to deploy novel methods of creating, acquiring, processing, manipulating, storing, or disseminating data or metadata; and/or

    • the availability of adequate resources to carry out the applications and novel integration of new theories, analysis, data, or methods regarding cognition, heuristics, and related phenomena.

  4. The SBIR/STTR programs require that projects funded contain both technical risk and technological innovation. Technical risk assumes that the possibility of technical failure exists for an envisioned product, service, or solution to be successfully developed. This risk is present even to those suitably skilled in the art of the component, subsystem, method, technique, tool, or algorithm in question. Technological innovation indicates that the new product or service is differentiated from current products or services; that is, the new technology holds the potential to result in a product or service with a substantial and durable advantage over competing solutions on the market. It also generally provides a barrier to entry for competitors. This means that if the new product, service, or solution is successfully realized and brought to the market, it should be difficult for a well-qualified, competing firm to reverse-engineer or otherwise neutralize the competitive advantage generated by leveraging fundamental science or engineering research techniques.

  5. What activities and expenses are appropriate to be funded in a Phase I project? What activities and expenses are not permitted?

    SBIR/STTR funding is for research and development (R&D) only. Generally, SBIR/STTR funding can be used for salary and wages for company employees, associated fringe benefits, materials and supplies, and a number of other direct costs needed to conduct the proposed R&D. SBIR/STTR projects may also fund consultants to the project and subawards to partner organizations. Some types of indirect costs necessary for the small business to conduct the project are also appropriate. Awardees may request indirect costs as per normal practice and as permitted by the Federal Acquisition Regulations (FAR), part 31.

    In general, SBIR/STTR Phase I funds may not be used for business development, marketing and sales, production, or any activity unrelated to the underlying research and development effort (either as direct or indirect costs). There are two notable exceptions: an awardee may request a small business fee as part of the award. This fee should be consistent with the normal profit margins provided to profit-making firms for R&D work; Such funds are unrestricted. Equipment purchases and foreign travel expenses are not permitted on a Phase I award but the purchase of equipment is permitted in Phase II.

  6. Will agencies fund work on a product that has already been developed? Will the program fund small businesses to pay sales and marketing, business development, or other related costs?

    many SBIR/STTR agencies provide funding for research and development (R&D) only. Notably, the Department of Defense (DOD) will fund research to make improvements to Commercial Solutions to meet a military purpose.

  7. Are new startup companies appropriate candidates for the program?

    Yes. Agencies encourage proposals from many types of small businesses. In fact, most Phase I awards are made to companies that are newly formed and very small. Companies with no current revenues and/or a minimal history of operations are encouraged to apply. However, those small businesses must show that they have a clear plan to quickly launch the company operations and assemble a team capable of carrying out the proposed Phase I project. Conversely, companies with a significant history of operations and/or R&D funding will be evaluated based on their track record of prior technology development and commercialization and whether SBIR funding will be catalytic to their further development.

  8. Are first-time entrepreneurs appropriate candidates to participate in the program?

    Many, if not most, SBIR/STTR awardee companies are launched by first-time entrepreneurs. Agencies encourage proposals from entrepreneurs of all experience levels — new and seasoned. It is critical that the team demonstrate commitment to advancing the technology to the market. The lack of a commercialization track record does not result in a disadvantage if the proposer shows commitment to the business' mission and a path to successful commercial outcomes.

  9. What are the expected outcomes (deliverables) of a Phase I project?

    The aims of the Phase I project should include a demonstration of the technical feasibility of the proposed innovation and thereby a path to advancing the innovation toward commercialization. The R&D outcomes best demonstrating technical feasibility vary widely based on the technology field and the particulars of the project.

    The required deliverable at the end of an SBIR/STTR Phase I contract or grant is a report that summarizes the project's technical accomplishments. Phase I outcomes take many forms depending on the technology area and stage of the research. Outcomes could be proof-of-concept data, a prototype, analytical/testing results of the product under development, etc.

    Phase I projects should mitigate the technical risks central to future commercial success. Phase I R&D work should present high technical risk; thus, not all projects will achieve the desired technical outcomes. Successful projects will naturally be better positioned to obtain follow-on funding, including SBIR/STTR Phase II funding.

What is a Direct to Phase II (D2P or D2P2)?

Since the SBIR program began over 30 years ago, there have been many accommodations made to address different ways that an eligible small business can meet the objectives of the SBIR program. Most of these variations are associated with Phase II.

As we introduce these variations, it is important to keep in mind that there are significant Agency differences. Therefore, not all of the items discussed will apply in every situation. When in doubt, please contact the SBIR or STTR program manager for the Agency of interest. The newest variations will be introduced first - these were brought about by the SBIR/STTR Reauthorization Act of 2011 and include Direct to Phase II awards, Sequential Phase II awards, Cross-Agency and Cross-program awards, Open Phase II competition, and Award caps.

Some variations that you will see are referred to as Phase IIA and Phase IIB awards. Again, please keep in mind that not every Agency offers these awards and that guidelines will vary within Agencies and often between entities within an Agency – so you should discuss these options with the Agency from which you have SBIR or STTR funding. Within the Department of Energy, for example, a Phase II grantee may request additional financial support through a Phase IIA grant. A Phase IIA award allows the grantee to complete the R&D associated with the initial prototype, product, or process development. By contrast, a DOE Phase IIB award provides additional financial support for a new R&D task that extends beyond the scope of the original Phase II grant.

The National Cancer Institute’s (NCI) SBIR program has developed an innovative funding opportunity called the SBIR Phase IIB Bridge Award to support the next stage of development for NIH-funded SBIR Phase II projects in the areas of cancer therapeutics, imaging technologies, interventional devices, diagnostics, and prognostics. The purpose of this award is to address the funding gap known as the “Valley of Death” between the end of the SBIR Phase II award and the subsequent round of financing needed to advance a product or service toward commercialization. To achieve this goal, the Bridge Award funding opportunity is specifically designed to incentivize partnerships between NIH’s SBIR Phase II awardees and third-party investors and/or strategic partners. Both SBIR and STTR Phase II awardees from other Federal Agencies are now welcome to apply.

Two additional capabilities were afforded by the 2011 Reauthorization, referred to as Cross-program and Cross-Agency awards. Cross-program awards enable a Phase I STTR award winner to receive a Phase II SBIR award or the reverse; while the concept of Cross-Agency awards enables any Agency to fund an initiative in Phase II that was initially funded by another Agency in Phase I. This can be particularly helpful when the Agency that funded the Phase I award no longer has the funds to support a Phase II initiative. Be sure to consult with the SBIR program manager responsible for your Phase I award to determine how to take advantage of these opportunities.

Another change brought about by the most recent reauthorization is the Open Phase II competition. While most civilian Agencies have always allowed a Phase I awardee to apply for a Phase II SBIR or STTR award, this was not previously the case with the Department of Defense. In the past, DoD Phase I awardees were invited to submit a Phase II proposal if the Service or Component had an interest in receiving a Phase II proposal from that firm. Now, all DoD Phase I awardees have the opportunity to submit a Phase II proposal to DoD without invitation, but the mechanism for doing so varies by Service and Component.

Finally, across all Agencies a ceiling or cap has been placed on all SBIR/STTR awards. An Agency may provide awards capped at 150% of the base - the cap then is $225,000 for each Phase I award and $1.5 million for each Phase II award. Please note the use of the word “may,” as Agencies have discretion regarding the size of their awards and may offer smaller awards so that the Agency can increase the number of Phase I awards that it makes. In addition, SBA has approved a topics list, which allows budgets to exceed the hard caps as long as the project topics are on the list. HHS has topic waivers for hard caps.

Please keep in mind that although the percentage of funding available through the SBIR and STTR programs has been increasing, the funding for these additional Phase II opportunities comes out of the same pot of money. Each Agency makes a decision about the size and number of awards that it can provide in Phase I, Phase II and as sequential Phase IIs. The Agencies with the smaller budgets are usually not in a position to fund the Phase II opportunities discussed here, but often welcome Cross-Agency awards as a means of bringing in new technologies to their programs that may meet urgent needs. It is the larger Agencies that tend to implement more of these Phase II opportunities. However, keep in mind that competition for additional Phase II opportunities is significant, as the number of these awards is limited. Please be sure to review the guidelines provided by each Agency which offers an SBIR and/ or STTR program and discuss the wisdom of taking advantage of these new opportunities with your technical monitor or the SBIR or STTR program manager.
