3 Houston innovators to know this week

Who's who

This week in Houston is chock full of events from The Houston Innovation Summit, but before you get too swept away, check out these three innovators to know this week.

We have a life-long innovator whose passion has taken him from industry to industry, a construction specialist joining a growing Houston startup, and a man who let his personal struggles motivate him to find solutions.

Brad Rossacci, creative director at Accenture's Houston innovation hub

The guest on the Houston Innovators Podcast this week is Brad Rossacci, who's passion exudes from him in person — and podcast too. One of his recent passions? The Digital Fight Club, which is coming to Houston on November 20. The event puts two "fighters" on a stage with a referee to discuss various technology topics — cybersecurity, medicine, etc.

"I really fell in love with the approach [the event] takes," Rossacci says. "It takes this format that allows you to share ideas in a very short-form content kind of way." Read (and listen!) more.

Michael Matthews, industry principal at Data Gumbo

Michael Matthews was tapped to lead a brand new market that Houston blockchain startup, Data Gumbo, has announced an expansion into: Construction. The company uses blockchain to make it easier and faster to process industry contracts, payment, and more.

"The construction industry lags far behind other industries in both productivity improvement and technology adoption, resulting in billions of lost value," Matthews says in a news release. "The way companies come together to execute projects remains essentially the same despite technology's improvement and we have to make fundamental, disruptive changes to deliver more value."

Brigham Buhler, founder of Ways2Well

Sometimes, it's just too hard to find the answers you seek in health care. The waiting rooms, the parking, the forms — it's all a bit much only to leave empty handed. This was Brigham Buhler's experience, and finally, after months, he learned he had a hormone deficiency. Now, Buhler's company, Ways2Well, allows patients to quickly do a blood test at a lab and receive their results digitally.

"While most virtual health care providers focus on sick care — treating patients experiencing symptoms that indicate sickness — Ways2Well is focused on preventative health care," says Buhler. Read more.

Houston blockchain company taps into a new industry, hires new exec

diversifying

A Houston blockchain company that makes it easier and faster to process industry contracts, payment, and more has diversified its business again.

After expanding into the water services industry in August, Houston-based Data Gumbo Corp. has announced its next market: Construction. The startup, which works out of The Cannon Houston, has hired industry veteran Michael Matthews hired as industry principal to work directly on the company's efforts in the $9 trillion sector.

"Construction is one of the world's largest industries, but it has clearly fallen behind others in adopting technology and driving efficiency," says Andrew Bruce, CEO of Data Gumbo, in a news release. "Michael is a recognized leader in the industry and his vision and experience make him an excellent fit to scale Data Gumbo into the construction sector."

Matthews has over 30 years of experience in construction. He says in the release that some of the issues of current practices result in 30 to 40 percent of project costs to be hidden, and he wants to use the GumboNet platform to provide solutions.

"The construction industry lags far behind other industries in both productivity improvement and technology adoption, resulting in billions of lost value," Matthews says in a news release. "The way companies come together to execute projects remains essentially the same despite technology's improvement and we have to make fundamental, disruptive changes to deliver more value."

Originally built for upstream drilling and completions within the oil and gas industry, Data Gumbo has grown its clientbase over the past few years. The company provides its blockchain-as-a-service services as a subscription for its clients.

Recently, the company was announced to be one of the two Houston-based companies in Plug and Play Tech Center's inaugural Houston cohort, and, earlier this year, the company was named among Crunchbase's top 50 hottest tech companiesCrunchbase's top 50 hottest tech companies. The growing company also hired another executive this summer —the company's new chief commercial officer is Sergio A. Tuberquia — following the closing of a $6 million series A round.

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.
