In most industries, there's a disconnect between startups and major corporations. The startups may have solutions for the big companies, but the two entities might not know how to connect with each other. That's something Accenture hopes to help with.

The company created Accenture Ventures to help connect the dots between emerging technology and big business. As the program has expanded, Thomas Rubenak was selected to serve the Southwest region as senior principal.

With a long career of working in tech, research and design, and startups, Rubenak hopes to use his experience to help grow Houston's blossoming innovation ecosystem.

"It takes a village. It's not just the amazing accelerators we have throughout the region," Rubenak says. "If you look at the Cannon, Houston Exponential, MassChallenge, and all of the ecosystem — it takes all of us together to prop up a thriving economy. That's what we're doing. We're changing not just the face of Houston but really impacting the startups as well as the clients we serve."

Rubenak spoke with InnovationMap to discuss the role Accenture Ventures plays in the ecosystem and how he sees innovation in Houston growing.

InnovationMap: You're new to your role, but you've worked with tech and startups for years. Tell me a little bit about your career to date. 

Thomas Rubenak: I come most recently from EY. I did a few assignments there, primarily working with the EY and Microsoft alliance. I was also a go-to-market lead for deep technical accounting for IPOs and other regulatory compliance issues. I worked a lot with the Entrepreneur of the Year program. Before that, I spent most of my career in tech research with Gartner and Forrester. This space is all about brilliant minds that really focus on helping the world understand what's next in emerging technology. I worked pretty extensively with venture capital, private equity and venture banks.

IM: While you’ve worked on projects across the country, you’ve been based in Houston, so you’ve been able to see the city transform, right?

TR: In my career, I've been really fortunate enough to align with amazing people in the market. Several years ago, we started a community just in Houston to bring entrepreneurs, angel investors, and some VC together. It was a nonprofit, grassroots effort called TeXchange; I just wanted to help entrepreneurs connect to sources of capital.

IM: How did Accenture Ventures get its start and what does it aim to do?

TR: Accenture realized four years ago that in order to stay competitive, it needed to tap the best of the best in the startup world. The only way to do that is to dedicate resources and people to that task, and that's how we started Ventures. As a recent joiner, my role is primarily the lead for the Southwest to bring the best of the startup ecosystem into our clients to help them solve their most pressing problems. And it's not just about problems, but also about opportunities.

It's a win-win-win. The client gets the benefit of having the best of the best and the startups get amazing exposure to companies they might not have been able to get in front of. And, Accenture is happy because it gets to serve the client.

Accenture works in multiple sectors, including resources (oil and gas), chemicals, mining — so for obvious reasons, the Southwest is a big sector for us — but, we also tap the health and public safety sectors.

As we look to design these arrangements with these startups and we find that there is a compelling need to invest in them, we'll become a minority investor. If that startup then has a M&A play that makes sense to everyone, we'll look into that as well.

IM: How do Accenture Ventures and the Innovation Hub work together?

TR: I am part of the hub, and I also serve the broader team.

What we bring to the table is amazing talent to data scientists to designers — many different resources — and we work with our clients to figure out what they want to solve or if there's a play in the market they are interested in. We can pull the best from Accenture and from the startup ecosystem to design solutions.

IM: What’s the most challenging thing about solving clients’ goals?

TR: It's not a challenge so to speak, but it's something I have to be mindful of, and that is always keeping the client's interest at hand, so recognizing and realizing that they have short- and long-term goals that they want to achieve.

IM: What's it like working with companies on the startup side?

TR: We seek specific types of startups. In order for us to be really effective, we keep a pulse on the market. Our focus is on companies that have gotten their source of funding, they've gone through their first round, companies that have great management who have been in industry or served big companies, and companies that are disruptors, innovators, or have something really compelling to bring to us. The challenge is that there are so many of them. There are so many great startup companies doing amazing things. But, as many startups as there are, there's just as many client issues.

IM: In your opinion, what challenges does the Houston innovation ecosystem still have to overcome?

TR: It's no secret that the economic engine of venture capital is in the east and west coasts. We have a lot of great VCs here, but it's about how do we keep our startups here. That's an issue that everyone talks about. But we also have seen a lot of startups move to Houston from other places. But, from the financial aspect of it, I think we could always use more of that. I personally don't think there will ever be another Silicon Valley, but we'll be something different. We'll be ourself. But, we do need those sources of capital in place. But something I want to mention is the diversity and the universities in Houston — we have a lot going for us.

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.
