The vitality of the United States’ federal innovation ecosystem relies heavily on the nation’s small businesses. Since 1982, the Small Business Innovation Research (SBIR) program has helped small firms translate ideas into prototypes and prototypes into solutions across the federal government. Its complement, the Small Business Technology Transfer (STTR) program, was created in 1992 to encourage commercialization of university research through partnerships with small businesses. SBIR and STTR funding has grown to almost $6 billion annually in recent years across 11 U.S. federal agencies.
Unfortunately, SBIR and STTR authorities will expire on September 30, and without congressional action, the United States risks undermining one of its core engines of technological innovation. Millions of dollars in SBIR awards could be delayed or potentially cancelled.
This moment calls not just for renewal but reform. To remain relevant and impactful, SBIR should continue to evolve—particularly by strengthening accountability and data collection on the transition rate of SBIR Phase II projects into actual programs of record. Reauthorization should be paired with improvements that make SBIR more measurable, effective, and aligned with national needs.
On September 9, 2025, Iowa Senator Joni Ernst came to CSIS to discuss the pressing need to reauthorize and reform SBIR. Senator Ernst called for reforms to SBIR outlined in her INNOVATE Act, which seeks to reorient the SBIR program away from what she calls “SBIR mills”—a select group of firms that are the most frequent SBIR awardees—and to increase the participation of firms that have never received a SBIR award before. SBIR is set to expire on September 30, and the debate over its future remains unresolved as negotiations continue in Congress.
SBIR and Innovation in the Federal Government
Leaders within the U.S. government are keenly interested in encouraging innovation. The use of SBIR and STTR grants, as well as Other Transactions (OTs), has dramatically grown as leaders view these efforts as a proxy for the federal government’s innovation effort. The Baroni Center for Government Contracting at George Mason University recently released its Government Contracting Trends and Performance Index, which studied 200,000 firms across the federal industrial base. The study found that the Department of Defense (DOD) and other federal agencies’ SBIR/STTR spending had grown to a total of almost $6 billion by 2023, nearly three times larger than in 2013, as illustrated in Figure 1.
Congress created SBIR because of its view that small businesses are the principal drivers of innovation. Small businesses are agile and can be closer to the cutting edge of new technologies than larger defense primes or traditional contractors. This makes them invaluable contributors to federal missions that require speed, ingenuity, and novel approaches. CSIS’s panel event on SBIR on September 9 explored the success stories of three small businesses that work for the federal government and highlighted how SBIR kick-started many of these firms’ ability to deliver solutions to the government. The SBIR program has been the subject of numerous reviews, which have found that the program has successfully stimulated innovation and encouraged various federal agencies to include small businesses in their research and development (R&D) efforts.
However, SBIR is a small part of the overall government spending directed towards small businesses. Despite the common mental image in senior federal leadership that small businesses are consistently engines of innovation, the majority of work performed by small businesses for the federal government is largely unrelated to innovation. The categories of work dominated by small businesses include civil engineering, software installation and programming, facility utilities installation and repair, administrative services, and nontechnical manufacturing.
Within the DOD, small businesses play an important role, though not always in areas typically associated with innovation. As shown in Figure 2, the DOD is the leading agency distributing SBIR funding by total amount of funds dispersed and number of individual grants. These allocations have steadily increased over the past decade for both the DOD and all other federal agencies. Beyond just SBIR, small businesses account for around a fifth of the DOD’s total contract obligations and a fourth of other federal agencies’ contract obligations. However, DOD contracts for small businesses are largely for facility services, administrative services, wholesalers, nontechnical manufacturing, and computer software installation services, which are not often thought of as sectors driving innovation.
The Challenge of Converting Innovation into Programs of Record
SBIR is not without flaws. Perhaps the most persistent challenge is the transition gap. SBIR grants have three phases: (I) Feasibility, (II) Prototyping, and (III) Commercialization. While Phases I and II are funded by agencies’ SBIR budgets, Phase III is not funded by the SBIR program and is designed to be the “success” condition—wherein the SBIR project accomplished the goal of becoming a commercially viable product with uptake by federal agencies or others. Small businesses can face great difficulty in moving from Phase II awards (where a prototype is developed) into Phase III or programs of record (where the government buys and scales the solution).
Improving transition rates from Phase II to Phase III requires more than just money. After all, SBIR funds cannot go towards Phase III commercialization spending. Instead, improving transition across what is commonly called the “valley of death” requires a deliberate effort to align SBIR awards with actual government needs, to involve program managers early in the process, and to track outcomes systematically. While not all innovative efforts should necessarily be adopted, a great loss for the federal government and its taxpayers is when SBIR projects succeed technically but fail bureaucratically, as they are unable to find champions in the acquisition system who can shepherd them into broader use.
A related challenge is that of proper metrics and data collection. While the usage of SBIR has exploded in the past several years, the U.S. federal government does not measure whether this funding is successfully serving the mission of creating innovation and commercialization. There is no public data that captures how many SBIR/STTR–funded prototype development programs have led to programs of record. Without the ability to quantify the conversion of SBIR programs from Phase II to Phase III, the federal government cannot see whether and where its spending is creating the desired effects. Moreover, in the absence of metrics, it is easy for critics to cast doubt on the program’s efficacy. As government leaders often use SBIR funding (along with STTR and OTs) as a proxy for overall innovation, the inability to measure SBIR commercialization hampers the government’s full understanding of its innovation ecosystem.
Considerations as SBIR Faces Reauthorization
SBIR is a powerful vehicle for translating U.S. ingenuity into solutions for the federal government. It has allowed small businesses to prove their ideas, and it has given the federal government access to a pool of innovation that may otherwise have been out of its view. Without reauthorization, the United States would be left with a weakened innovation pipeline, even as global competitors double down on state-backed technology development.
However, Congress should not ignore SBIR’s current shortcomings. Some experts call for expanding participation beyond the current SBIR and STTR recipient base. They point to Government Accountability Office findings that 10 percent of Phase II dollars were awarded to 22 firms, which represent fewer than 1 percent of all Phase II awardees, from FY 2011 through FY 2020. Senator Ernst has championed the INNOVATE Act to cap lifetime SBIR awards to a single firm at $75 million. Other experts argue that multiple SBIR awards to the same firm can advance the goals of innovation by building momentum, creating expertise, and helping bridge the acquisition valley of death for small firms.
Reauthorization can be paired with reform. The administration could collaborate with Congress to collect and publicly disseminate greater data on SBIR/STTR to better quantify innovation spending and successes. Federal agencies should be required to measure and report transition outcomes. This data would enable the government to more clearly understand the innovation and commercialization cycle, as well as the impact of capabilities derived from SBIR spending. Over time, a data-driven approach would raise the overall effectiveness of the program.
Congress should act swiftly to reauthorize SBIR. At the same time, policymakers should address implementation issues. By building stronger metrics, ensuring better alignment with operational needs, and smoothing the transition from prototypes to programs of record, SBIR can continue powering U.S. innovation for the federal government in the decades ahead.
