Earlier this month, 16 medical device companies wrapped up their time at the Texas Medical Center's accelerator program and pitched their companies to fellow health professionals, guests, and more. While each made important connections in the local ecosystem during the program, a quarter of the entrepreneurs had roots in Houston already.

Four of the 16 TMCx09 companies that are headquartered in Houston. They have built solutions within sepsis, surgery, and transplant spaces in health care. Here's a little more about the homegrown companies that pitched at the event.

The standard practice for acute heart failure patients is very invasive, says William Altman, CEO of CorInnova.

"The problem with existing devices is that they have invasive blood contact," Altman says. "Problem with that is blood contact is bad. It can cause up to 15 percent rate of stroke, which could kill you, and after five to seven days it provides 10 percent rate of blood destruction and has a 47 percent rate of kidney disfunction."

CorInnova's technology features a device that can be easily inserted through a 1-inch incision, and then be used for increase blood pumping by 50 percent.

"Surgeons tell us this is less invasive than minimally invasive aortic valve replacement, which is a widely done surgery, so this promises widespread adoption for our technology as we get it approved," Altman says.

The human prototype is expected to be ready in two years, with the next year being focused on animal studies. CorInnova is raising $12 million to accomplish its goals.

An estimated 10 to 15 percent of the United States population will get a gallstone in their lifetime. Should one of those stones cause trouble or blockages, the only solution is to remove the gallbladder completely through surgery. However, Matthew Nojoomi, CEO and co-founder of Ictero Medical, has another idea.

Ictero Medical has created a minimally invasive treatment that uses cryoablation to defunctionize the gallbladder without having to remove it.

"The CholeSafe System not only treats the source of the disease, but it leverages existing clinical workflows that doctors use to access the gallbladder," says Nojoomi, adding that the process only uses mild station and pain control.

The company expects to get to humans in the next two years, and has launched a financing round.

PATH EX

Currently, sepsis is hard to identify in patience. Even if a patient is in a hospital, and that hospital knows the patient has sepsis, the individual still has a 38 percent chance of dying, says Sinead Miller, CEO of PATH EX.

"Right now the problems associated with sepsis are very clear," she says. "It's the leading cause of death in our ICUs, and it's also associated with the highest hospital cost and readmission rates."

PATH EX's technology allows medical professionals to better diagnose and treat sepsis. The PATH EX therapeutic device can be hooked up to a patient and flow his or her blood through the machine to capture bacteria, clean and recirculate the blood, and faster diagnose what sort of bacteria the patient has attracted. The device technology is similar to hemo hemodialysis, Miller explains.

The Houston company, which recently won big at the Ignite Healthcare Network's Fire Pitch Competition, was named an honoree within the Johnson and Johnson Breakthrough Medical Technologies Quickfire Challenge.

The company was recently received clearance from the Food and Drug Administration as a breakthrough device technology. PATH EX closed its $615,000 seed round — with plans for a series A next year — and has received $1 million in SBIR grant funding. The company was founded two years ago, and relocated to call Houston HQ this year.

Volumetric

Volumetric is banking on their technology being among the inventions that will lead the medical industry into the future. The human tissue-printing technology company has created the 3D printer and the "ink" that can create whole organs for transplant.

"We can create complicated vascular architectures inside of soft water-based gels, in this case, mimicking the structure and function of human lung tissue," says Jordan Miller, CEO. "We can oxygenate red blood cells."

The company is commercializing its technology and has three streams of revenue, which as generated almost $1 million in revenue in Volumetric's second year. The company is also in the process of closing its seed round of fundraising.

Earlier this year, the startup, which works out of Rice University, was featured on the cover of Science magazine.

TMC Innovation Institute announces redesign of its acceleration program for 2020

X-citing news

TMCx has been helping medical device and digital health startups create solid business plans and lasting relationships with Texas Medical Center institutions for five years, and on the accelerator's fifth anniversary, the team announced it's mixing things up a little to better accomplish those goals.

On Nov. 7, TMCx celebrated the conclusion of its ninth cohort, and 16 medical device companies pitched to a crowd at the TMC Innovation Institute. The companies in this cohort, just like the ones before it, were selected based on their technologies that solved a problem using digital health or medical devices. However, previously, the TMC's member institutions weren't directly part of the process until after the cohort was selected.

Based on feedback from alumni, member institutions, corporate partners, and stakeholders, TMCx has redesigned the program so that next year, the accelerator will focus on the specific needs of the needs that the organizations within the TMC have identified.

"Our focus going forward is on our member institutions — the clinics, the hospitals, and our partners who really bring forward these technologies into the future," says Emily Reiser, innovation strategist at the TMC Innovation Institute.

TMCx will become a needs-based accelerator program, Reiser says, and the team at the accelerator will partner with member institutions to run specific cohorts matched to their areas of interests.

The first step will be to identify these areas of interest, then in February of 2020, TMCx will invite a number of companies related to those interests to Houston for two weeks. The TMCx team, member institutions, and other stakeholders will get to interact with the companies and see how they stack up against each other, and to see if they can really fill the needs of the hospitals, clinics, and more.

Finally, after narrowing down the companies, the final startups and entrepreneurs will be invited to participate in a six-month accelerator program that will provide the same resources, connections, and programming that TMCx has always provided to advance the health startups.

Reiser says the TMCx team and all its partners will help identify the missing pieces these companies have and provide solutions, as well as making the right connections to all the right pilot partners, investors, clinical trial experts, and more.

"We'll be here to help them fill those gaps and make sure they have lasting relationships with our clinical partners in the hospitals," Reiser says.

Lasting impact

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.

Virti

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

Cody Duty/TMC

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.

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
