Grants are everywhere, all the time, but often seem unobtainable for startups. Most companies tell me about their competitors winning grants but don’t know how to secure non-dilutive funding for themselves. It’s true that the SBIR program is competitive — with only 10 to 15 percent of applicants receiving awards — but with a little guidance and perseverance, they are most definitely obtainable.

An SBIR overview

The Small Business Innovation Research program was introduced on the federal level in 1982 with the purpose of de-risking early technologies. While most investors are hesitant to invest in a company that’s still in ideation, the SBIR program would provide an initial level of feasibility funding to develop a prototype. The program issues funds to companies without taking any equity, IP, or asking for the money back.

Since its inception, the SBIR program has funded over 200,000 projects through 11 different federal agencies, including, but not limited to, the Department of Defense, the National Institute of Health, and the National Science Foundation. Federal agencies with R&D budgets over $100 million dedicate at least 3.2 percent of their budget to the SBIR program to fund research initiated by small businesses.

Eligibility and application process

It is no surprise that only small businesses can apply for this non-dilutive funding. For SBIR purposes, a small business is defined as being a for-profit entity, smaller than 500 employees, 51 percent owned by US citizens or permanent residents, and not primarily owned by venture capital groups. This small business must also have the rights to the IP that needs de-risking.

To apply, the small business must have a specific project that needs funding. Normally, this project will have three specific aims that detail the action items that will be attempted during the funded period. Some agencies require a pre-application, like a letter of intent (DOE) or a project pitch (NSF). Others don’t have a screening process and you can simply submit a full application at the deadline. Most agencies published examples of funded or denied applications for you to review.

SBIR phases

Phase I of the SBIR program is the normal entry point for every agency. It takes your product from ideation, through a feasibility study, to having a prototype. While agencies provide various funding amounts, the range is between $75,000 to $300,000 for 3 to 12 months of R&D activities. Applications contain a feasibility research plan (around six pages), an abstract, specific aims, supporting documents, and a budget.

While some programs allow for Direct to Phase II (D2P2) applications, most don’t apply for Phase II until they have secured Phase I funding. This second phase allows companies with completed feasibility studies to test their new prototype at a larger scale. The budgets for this phase range from $600,000 to $3 million and span an average of two years. The research plan is twice as robust and a commercialization plan is also needed.

Tips for success

If you’re wondering if your technology would be a good fit for a certain program, you can start by looking at the SBIR website to see the previously funded projects. The more recent projects will give you an idea of the funding priorities for each agency. Most abstracts will allude to the specific aims, meaning you can get a sense of the research projects that were approved. If you regularly see an agency funding projects similar to yours, you can search sbir.gov/topics for that agency’s research topics and upcoming deadlines.

Your team is one of the most important aspects of the application. Since you will be reviewed by academic experts, it’s helpful to have a principal investigator on your project that has a history of experience or publications with similar technology. Keep in mind that this principal investigator must be primarily employed by your company at the time of the grant. If this individual is employed by a university or nonprofit research organization, consider taking the STTR route so you can utilize their expertise.

Preparing Phase I applications should take no less than eight weeks, and Phase II should take at least ten. Your first step should be read the entire solicitation and create action items. The early action items should be

  1. Completing government registrations, like SAM.gov
  2. Writing your abstract and specific aims
  3. Contacting the program manager or director for early feedback

Any bids, estimates, or letters of support may also take time to receive, so don’t delay pursuing these items.

Don’t stop trying

If you speak to any program officer, they will encourage you to keep applying. For resubmissions, you will have a chance to explain why your previous application was denied and what you’ve done to improve. Most companies receive funding on the resubmission. If you get the feeling that a specific agency isn’t the right fit, reach out to other agencies that may be interested in the technology. You may realize that a small pivot may open up better opportunities.

There are frequently published webinars from different agencies that will give overviews of the specific solicitations and allow for Q&A. If you feel stuck or are still concerned about getting started, reach out to an individual or group that can provide guidance. There are plenty of grant writers, some of which have reviewed for the SBIR program for different agencies, who can provide strategy, guidance, reviews, and writing services to provide different levels of help.

Securing SBIR funding can be a game-changer for startups. While the process may seem daunting at first, with the right approach and persistence, it’s very obtainable. Remember, each application is a learning experience, and every iteration brings you closer to success. Whether you seek support from webinars, program officers, or professional grant writers, the key is to keep pushing forward. The potential rewards far outweigh the challenges, and with determination, your startup could be the next SBIR success story.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
