A handful of Houstonians have been named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Kip Daujotas is an investment associate at Aramco Ventures, a $7.5 billion venture capital arm of the world's largest energy company. Houston is the Americas headquarters for Saudi Aramco. Since its inception in 2012, Aramco Ventures has invested in more than 100 tech startups. Daujotas joined the team over two years ago after studying for an MBA at Yale University. He led Aramco’s first direct air capture (DAC) investment — in Los Alamos, New Mexico-based Spiritus.

Also representing the corporate side of the industry, Wenting Gao immigrated from Beijing to obtain an economics degree from Harvard University, then got a job at consulting giant McKinsey, where she recently became the firm’s youngest partner. Gao works on bringing sustainability strategies to energy and materials companies as well as investors. Her areas of expertise include battery materials, waste, biofuels, and low-carbon products.

Last but not least, Houston entrepreneur Rawand Rasheed is co-founder and CEO of Houston-based Helix Earth. He co-founded the startup after earning a doctoral degree from Rice University and co-inventing Helix’s core technology while at NASA, first as a graduate research fellow and then as an engineer. The core technology, a space capsule air filtration system, has been applied to retrofitting HVAC systems for commercial buildings.

Each year, Forbes 30 Under 30 recognizes 600 honorees in 20 categories. The 2025 honorees were selected from more than 10,000 nominees by Forbes staff and a panel of independent judges based on factors such as funding, revenue, social impact, scale, inventiveness, and potential.

Specifically, the Energy & Green Tech category recognizes young entrepreneurs driving innovation that’s aimed at creating a cleaner, greener future.

“Gen Z is one of the fastest-growing groups of entrepreneurs and creators, who are reshaping the way the world conducts business, and our Under 30 class of 2025 proves that you can never begin your career journey too early,” says Alexandra York, editor of Forbes Under 30. “With the expansion across AI, technology, social media, and other industries, the honorees on this year’s list are pushing the boundaries and building their brands beyond traditional scopes.”

Houston corporate venture leader calls for collaboration across sustainable fuel, innovation community

HOUSTON INNOVATORS PODCAST EPISODE 212

When it comes to the future of aviation — namely, making it more sustainable, a rising tide lifts all boats. Or, in this case, planes.

Andrew Chang, managing director of United Airlines Ventures, explains that working together is the key for advancing sustainable aviation fuel, or SAF. That's why United Airlines started the Sustainable Flight Fund, a $200 million initiative with support from industry leaders, including Air Canada, Boeing, GE Aerospace, JPMorgan Chase, Honeywell, Aramco Ventures, Bank of America, Hawaiian Airlines, JetBlue Ventures, and several others.

"We all recognize that we may compete in our core business, but with the importance of sustainable aviation fuel and given that it's an industry that doesn't exist — you can't compete for something that doesn't exist — let's collaborate and work together to explore technologies that can directly or indirectly support the commercialization and production of sustainable aviation fuel," he says on the Houston Innovators Podcast.

Within United Airline Ventures, Chang's job is to find technology to invest in across the aviation industry spectrum — from SAF to digital technologies that will improve the United customer experience. This means working with startups and other organizations to find the best fit — and, because he's based in Houston, one of United's seven key hubs, this means knowing and interacting with local innovators.

"The knowledge base and the capabilities are here — that's undebatable," Chang says of the Houston innovation ecosystem. "The next step is making sure we're accessing, promoting, collaborating, and learning from one another."

Again, as Chang recognizes, collaboration is key to further developing the ecosystem, "so that we're not trying to solve the same problem in a vacuum," he explains.

United Airlines recently signed an offtake agreement with Cemvita Factory, a Houston biotech startup that's working on SAF. Chang discusses this partnership on the show, as well as explaining how he works with other startups and what he's looking for.

Howard Berman, as co-founder and CEO, has been at the helm of Coya Therapeutics as its hit some major milestones — from raising over $20 million in venture investment to taking the company public. Coya's IPO occured in a tough market — only 12 biotech companies went public last year, Berman explains on the Houston Innovators Podcast. To Berman, that just proves how passionate the team was about getting this product to those who need it.

"It really says something for the fortitude and our team to come together to make it happen," he says on the show. "We're able to deliver and execute in a difficult market climate.

"Once you're a public company, you have different expectations," he continues. "But you also have the opportunity to go out and attract additional investors in ways you can't do as a private company." Read more.

Aramco joins Houston climatetech incubator with major partnership

seeing green

Houston-based Aramco Americas, an arm of the Saudi Arabian energy giant, has joined climatetech incubator Greentown Labs as a top-tier partner.

“Aramco is committed to advancing technology solutions to lower carbon emissions. This partnership with Greentown Labs will deepen our ongoing engagement with climatetech innovators and startups,” Nabeel AlAfaleg, president and CEO of Aramco Americas, says in a news release.

In its role as a “Terawatt Partner,” Aramco Americas will gain access to activities within Greentown’s industry and entrepreneurial network. In addition, Aramco Americas will participate in Greentown’s Industry Leadership Council, an advisory group. Jim Sledzik, managing director of Aramco Ventures North America, will serve on the council.

Aramco’s partnership with Greentown Labs comes on the heels of last year’s announcement of the company’s $1.5 billion fund to invest in technology that supports the ongoing energy transition. Managed by Aramco Ventures, the VC arm of Aramco, the fund focuses on carbon capture and storage, greenhouse gas emissions, energy efficiency, nature-based climate solutions, digital sustainability, hydrogen, ammonia, and synthetic fuels.

To date, Aramco Ventures has invested in 22 startups and high-growth companies involved in the sustainability sector.

“Aramco Americas and Aramco Ventures have already exemplified what we look for in a partner: support of our entrepreneurs through investment and pilot opportunities, and engaging with our communities in Houston and Boston in the spirit of sustainability and climate action,” says Kevin Taylor, interim CEO and chief financial officer of Greentown Labs.

Greentown operates climatetech incubators in Houston and Somerville, Massachusetts.

Houston lab-test startup seeks $1M for nationwide expansion

Testing Access

Health care industry veteran Jim Gebhart knew there had to be a better way for patients to access lab services, especially those with high health insurance deductibles or no insurance at all.

“This challenge became deeply personal when a close family member developed a serious illness, and we struggled to secure prompt appointments,” Gebhart tells InnovationMap. “It’s incredibly frustrating when a loved one cannot receive timely care simply because of provider shortages or the limited capacity of traditional clinics.”

Driven by the desire to knock down lab-test barriers, Gebhart founded Houston-based TheLabCafe.com in 2024. The platform provides access to low-cost medical tests without requiring patients to carry health insurance. TheLabCafe serves patients in six states: Texas, Georgia, Louisiana, Nevada, New Mexico and Oklahoma. Gebhart, the startup’s CEO, says that by the end of March, LabCafe will be offering services in 20 more states and the District of Columbia.

Gebhart has spent more than 30 years in the lab industry. His career includes stints at Austin-based Clinical Pathology Laboratories, Ohio’s Cleveland Clinic Laboratories and Secaucus, New Jersey-based Quest Diagnostics.

“Since nearly 80 percent of disease diagnoses rely on laboratory testing, I decided to leverage my background to create a more accessible, self-directed process for individuals to order blood and urine tests on their own terms — when and where they need them,” says Gebhart.

So far, Gebhart is self-funding the startup. But he plans to seek $700,000 to $1 million in outside investments in late 2026 to support the nationwide expansion and the introduction of more services.

TheLabCafe contracts with labs for an array of tests, such as cholesterol, hepatitis, metabolic, testosterone, thyroid and sexually transmitted infection (STI) tests. A cholesterol test obtained through TheLabCafe might cost $29, compared with a typical cost of perhaps $39 to $59 without insurance.

A health care professional reviews every test, both when the test is ordered and when the results are delivered, often within 24 hours. After receiving test results, a patient can schedule a virtual visit with a health care professional to go over the findings and learn potential treatment options.

Gebhart says TheLabCafe particularly benefits uninsured patients, including those in Texas. Among the states, Texas has the highest rate of uninsured residents. U.S. Census Bureau data shows 21.6 percent of adults and 13.6 percent of children in Texas lacked health insurance in 2024.

“Uninsured patients often pay the highest prices in the health care system,” Gebhart explains. “We address this by offering straightforward pricing and convenient access to testing without requiring insurance.”

“Our rates are intentionally set to remain affordable, helping individuals take a proactive approach to their health,” he adds. “Regular testing enables people to identify potential health issues early and track their progress as they make lifestyle changes. Ultimately, you can’t measure improvement without data — and laboratory results provide that data.”

Houston geothermal startup secures $97M Series B for next-gen power

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.
