At the conclusion of TMCx's recent Digital Health cohort — the most international group to date — there was only one Houston company among the 19. However, most of that group have developed a presence in Houston throughout the program.

Besides just being based here in Houston for four months, TMCx associate director, Lance Black, says the city has a lot to offer these startups.

"Why Houston? Why are these companies coming from everywhere to be here? Three big reasons," he says to the crowd at Demo Day. "The size and scale of the Texas Medical Center, the diversity of Houston, and the willingness and hunger of Houstonians wanting to be involved in innovation."

From pilots and partnerships to funding and mentorship, these TMCx08 companies announced the impact they've made on Houston at the Demo Day on Thursday, June 6. Meanwhile, TMCx had its own announcement that it would create early stage programming for professionals connected to the Texas Medical Center.

"It is the TMC's mission to advance health care, research, and education. It's our mission at the Innovation Institute to bring value back to the med center through health care technology," Black says. "And, through TMCx, we do that through startup companies."

Here are some examples of TMCx companies setting foundations in the Houston ecosystem.

California-based Virti has developed an extended reality simulation technology for training medical staff. It's a cheaper, more effective way to train personnel, says Alex Young, CEO of the company.

Virti was selected to be in England's National Health Service accelerator — the only evidence-based AR/VR training company ever to be picked for the program, says Young.

With a presence in California and England, Young says he's also planted roots in Texas too, with sales representation based in the TMCx offices.

"In the time that we've been here, we've closed deals in Texas and back in California," Young adds.

Optellum

Optellum is changing the way lung cancer is being detected. With the startup's artificial intelligence-enabled detection software, oncologists can better identify at-risk patients, which translates into more treatment for those in need, and less for those who don't.

The company, which is based in the United Kingdom, has raised funds abroad while networking locally.

"TMCx has been amazing for a small British company like us. We have started pilots and trials at four TMC member institutions," says Vaclav Potesil, CEO.

Oncora Medical

Angela Holmes, the director of product and customer solutions of Oncora Medical, sets the stage at her company's Demo Day pitch by telling a story of her friend's daughter who was diagnosed with cancer. She was forced to pick between two treatment options. She had no data or insights to help.

Oncora Medical's mission is to help fight cancer using data. Though based in Philadelphia, Oncora has Houston ties, since it formed a partnership with MD Anderson Cancer Center in April of 2017.

"We are so honored and gratified to be in a strategic, multi-year collaboration with MD Anderson to build this software system to save the world," Holmes says.

PreOp MD

Within health care, the projected annual aggregate surgical expenditure by 2025 is expected to be $912 billion, says Christiana Obi, founder and CEO of PreOp MD, and a Houston-based anesthesiologist. She sees lack of information causing wasted surgical resources regularly.

PreOp MD — the only Houston-based TMCx company this cohort — has an app that allows for pre-procedure education, communication, and more that aims to prevent surgical delays.

While based here, PreOp is truly rooted in Houston, and even more so with their latest news.

"We are happy and excited to say that we have landed our first medical pilot at an medical right here in town," Obi says.

RoundTrip

RoundTrip has a solution to 3.6 million missed or postponed medical visits that happen annually that are inconvenient to hospitals and a major health risk to the population: Ride sharing.

The Philadelphia-based company enables all forms of transportation and puts the power in the hands of the medical institution. From ambulances to other medical vehicles, the company can optimize utilization of all vehicles to get patients to their appointments and even has a partnership with Lyft.

While completing the TMCx program, RoundTrip closed its Series A round of $5.14 million led by Virginia-based Motley Fool Ventures in April. The funds will be used for expansion.

"Now we have all this new money to expand really rapidly. Texas, we're coming for you, whether you're ready or not," says Jackson Steeger, account supervisor.

Meru Health

Meru Health is also one of the 2019 TMCx Digital Health companies that has raised money while in the program. Palo Alto, California-based Meru completed a $4.2M raise in April 2019. The round was led by San Francisco-based Freestyle Capital.

Access to mental health professionals is increasingly more difficult, so Meru Health has created a low-cost digital clinic that offers an app-based treatment program from licensed therapists. Kristian Ranta, CEO and founder, while not yet providing specifics, that they aren't done in Texas.

"I'm happy to say there's some good stuff brewing here in Texas for us. More to follow," says Ranta.

Cloud 9

Mental health is a key contributing factor in the legal system cycle, but it doesn't have to be Liz Truong, co-founder of Cloud 9. Better educating officers and providing them with mental health resources is the best way to get them out of the hospitals and court rooms and back out in the field to protect the city.

While some police departments have instituted ride-along programs with mental health professionals that have showed success, it's expensive for the police department and risky for those professionals. Cloud 9 has created a digital solution.

"We proved this works in the Harris County Sheriff's office right here in Houston," says Truong. "Officers reported that 97 percent of Cloud 9 care was superior or equal to their current program and showed an immediate 632 percent return on investment for our customers in the same budget cycle compared to what they were already spending."

Truong also says they have other local customers they are working with, including the Harris County Health Department.

Axem Neurotechnology

Recovering stroke patients need rehabilitation to get back to 100 percent, but getting patients into the facility is challenging and at-home compliance is hard to track.

Canadian company Axem Neurotechnology has a solution. With their external device and mobile application, physical therapists can track progress and communicate with patients remotely.

"When we talk to rehab professionals, they are excited about what we're doing," says Tony Ingram, CEO and co-founder. "That's why we have leading institutions in both Canada and the U.S. onboard for clinical trials — this includes TMC's own TIRR, which is consistently ranked in the top five rehab centers in the U.S. We're collecting core baseline data in the most diverse city in the country."


Correction: A previous version of this article said Oncora's partnership with MD Anderson was formed during the TMCx program, when the partnership began in 2017.

Rice University breaks ground on new innovation hub, The Arc

breaking ground

Construction is officially underway on Rice University's The Arc in Houston’s Ion District.

The university broke ground on the 200,000-square-foot research, corporate innovation and office building on Nov. 4. The facility will share a plaza with the existing Ion building, fostering collaboration within the innovation space, according to Rice.

“The Arc will bring Rice’s extraordinary research and talent and Houston’s impactful innovation ecosystem into even closer connection with the industries and innovators working to solve some of the world’s most consequential challenges,” Rice President Reginald DesRoches said in an announcement. “That constant exchange of ideas and expertise will help move discoveries more rapidly from the laboratory to real-world impact.”

Construction is scheduled to be completed by Q2 2028. Rice Real Estate Co. is developing the project, and Rice University will occupy about 80,000 square feet in the building (about 40 percent). Preleasing has begun, with floor plans ranging from 28,000 to 31,000 square feet.

The Arc will feature conference and meeting spaces, an amenity lounge, fitness center, outdoor plazas, underground parking, and on-site retail and dining, according to the release.

It aims to host tenants focused on artificial intelligence and machine learning, data science, robotics, quantum science and engineering and energy, including Rice's new AI Foundry.

Rice says the AI Foundry will be a space where university experts and partners can support organizations with AI challenges. Rice recently committed to hiring 75 new AI-focused faculty and announced plans to launch a new Master of Artificial Intelligence (MAI) next fall.

“The AI Foundry is exactly the kind of collaboration the Arc is designed to enable,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs at Rice, added in the release. “By bringing Rice researchers together with industry partners in a shared environment, we can accelerate the movement of ideas from research into practical applications while helping organizations build the capabilities they need to succeed as AI continues to evolve.

Developers of The Arc are targeting LEED Gold certification by incorporating smart building automation and energy-saving features into the project's design. Rice first announced the project in September 2025.

Houston battery tech startup FlowCellutions acquired by Katy energy co.

M&A

Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

3 fast-growing Houston scaleups named Innovation Awards finalists

meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of the 2026 Houston Innovation Awards, our Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.
