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.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."
