Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from fintech to health care DEI — recently making headlines in Houston innovation.

Steve Latham, co-founder and CEO of DonateStock

For the third time in his career, serial entrepreneur Steve Latham recession activity, so he feels confident he knows the playbook of how to handle what's on the horizon. For his latest venture, Donate Stock, a tech platform that simplifies stock donation for both the donor and the beneficiary, he's focused on weathering whatever storm is incoming.

"We've raised more money to extend our runway, and we're keeping a super tight lid on expenses because your cash is your oxygen," he says. "There are companies going out of business in our industry right now that had really promising businesses but just spent too much money before they could get to the revenue phase."

He shares the background story on DonateStock and his own career on last week's Houston Innovators Podcast episode. Read more and stream the episode.

Innovation and equity are two things they have to go together — and Houston Methodist knows that. Which is why Arianne Dowdell serves as vice president and chief diversity, equity and inclusion officer at Houston Methodist. Under her leadership, the health care provider is putting the patients at the forefront of the hospital system's priorities through its DEI initiatives.

In an interview with InnovationMap, Dowdell shares more about these ongoing initiatives and her role, as well as the importance of DEI in innovative health care.

"It doesn't matter if you're down here in the medical center or out in Baytown," she says. "The innovation and what we're thinking about and the technologies and the way that we communicate with our patients, all that is part of innovation, which helps our DEI initiatives become more successful in everything that we're doing."

A clinical-stage biotech company based in Houston has announced the closing of its $15.25 million IPO.

Coya Therapeutics, now trading under the ticker COYA, announced this week that its IPO — previously disclosed in December — has closed its initial public offering of 3,050,000 shares of its common stock and accompanying warrants to purchase up to 1,525,000 shares of common stock, per a news release. Howard Berman, CEO of Coya Therapeutics, has lead the company since February of 2021. Read more.

Houstonian and serial entrepreneur plans to scale nonprofit fintech tool

Houston innovators podcast episode 167

Donating stock can be a smart way to offload assets and optimize a donation — but Steve Latham thought it was so cumbersome a process that it didn't even feel worth it.

"It was such a hassle that I never did it again," says Latham on the Houston Innovators Podcast.

That opportunity for innovation stuck with Latham as he advanced his career in AdTech in New York before moving back to Houston a few years ago. A serial entrepreneur, Latham was an early co-founder of the Houston Technology Center.

His latest venture is DonateStock — a tech platform that simplifies stock donation for both the donor and the beneficiary. The early version of Latham's vision was to clear up the lack of communication the original process had — nonprofits receiving stock donations were never notified about who made each donation.

The next phase for the fintech company, as Latham explains on the show, is to scale this idea by way of channel distribution, rather than just directly working between donor and nonprofit. He says he wants DonateStock to be a featured as an "easy button" option wherever donations are accepted online.

"Now that we've proven and shown that our process works," he says, "let's scale that to make that button available to the 20 or so online donation platforms."

In order to accomplish this goal, Latham is preparing to fundraise early this year, but it's a challenging time for fintech amid economic uncertainty, he says. So far, the company has raise $2.25 million from within the company's network along with angel and family office investment.

This is the third time in Latham's career that he's seen this recession activity, so he feels confident he knows the playbook of how to handle what's on the horizon.

Latham shares more about the difference his company is making within the nonprofit sector, as well as his passion for Houston and its local tech ecosystem — which he's seen grow up from afar — on the podcast episode. Stream the episode below, or wherever you listen to your podcasts.

Houston fintech startup snags Capital Factory's $50,000 pitch investment prize

winner, winner

Capital Factory, one of the most active startup investors with a presence across Texas, recently hosted a virtual pitch competition — and one Houston startup took home the big prize.

As a part of the Houston Tech Rodeo, Capital Factory hosted its $50K Houston Investment Challenge with five finalists — DonateStock, Elastique, Elemental Coatings, M&S Biotics, and ScalaMed. The panel of judges included Andy Cloyd, vice president of Revolution; Aleece Hobson, venture partner at HX Venture Fund; and Juliana Garaizar launch director of Greentown Labs.

DonateStock, a tech-enabled tool that automates the stock donation process, took home the big win. Steve Latham, founder and chairman of DonateStock, presented the company's pitch and explained how the tool has the potential to unlock $100 billion for nonprofits.

"A lot of people aren't aware about the benefits of donating stock," Latham explains. "If you're sitting on stock that you've owned or several years that's appreciated quite a bit. If you sell it, you pay capital gains tax — anywhere from 15 to 30 percent. If you donate it, you avoid the tax and you get a big write off, you can deduct the full market value of the donated stock."

He goes on to explain how only 2 percent of people donate stock — and its due to the archaic process that it takes. DonateStock's platform optimizes the education of donors, the connection of nonprofits to new donors, and the simplification of the process. What used to take hours now takes just 10 minutes, Latham says.

Nonprofits get a free page, free customer support, and there is no fee to be on the platform, and DonateStock makes a 2 percent transaction fee. The company already has 40 nonprofits on the platform, and over 70 in the queue to sign up. The goal, Latham says, is to have 900 organizations online by the end of the year. He's already seen a lot of interest in light of the pandemic.

"This is the time to solve this problem," Latham says. "If you have friends at nonprofits or charities, you know what the pandemic did to giving programs. They've all been devastated and they have gotta find new ways to diversify and grow their revenue."

DonateStock anticipates a seed round later this year. It's the third startup Latham has worked on with his co-founder.

"We see a path to building a billion-dollar company over the next five years while impacting millions of lives around the world," he says.

Each of the other finalists' consolation prize is a connection and a foot in the door at Capital Factory, says CEO Joshua Baer.

"Every time we do one of these, we meet a bunch of companies that we end up working with — and many of whom we end up investing in," he says at the virtual event. "We're going to be following up with all of the companies from today. Anyone who was a finalist and up on the stage is someone we are excited about and interested in working more closely with."

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.
