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

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 cleantech, space startups named to World Economic Forum cohort

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Houston Methodist receives record $110M gift, names future tower

historic gift

Houston Methodist has received the largest gift in the health system's history to establish new funds for neurological, neuroscience, and women’s health research and treatment.

The $110 million gift comes from Houston-based The Brockman Medical Research Foundation, which supports education and research in the science, medicine and healthcare fields. In response, Houston Methodist announced that it will name its forthcoming 26-story hospital facility the Brockman Centennial Tower.

The tower’s entrance will be named the Anna Margaret Bellows Centennial Hall to honor Anna Margaret Bellows, a young camper who died during the Camp Mystic flooding last summer.

“This extraordinary gift accelerates discovery and transforms how care is delivered,” Dr. Marc Boom, president and CEO of Houston Methodist, said in a news release. “We are grateful to The Brockman Medical Research Foundation for its incredible generosity and vision that will help change the lives of generations of patients. Naming Centennial Tower in recognition of this gift reflects the scale of this commitment and its impact on the future of neuroscience, neurological care and women’s health.”

The gift will be divided into two parts:

  • $100 million will go toward creating an innovation fund within the Houston Methodist Academic Institute and the Houston Methodist Neurological Institute
  • $10 million will be devoted to Houston Methodist's Department of Obstetrics and Gynecology

“This tremendous gift will accelerate translational research that broadens our understanding of neurological and other diseases,” Dr. Jenny Chang, president and CEO of the Houston Methodist Academic Institute, added in the release. “It will allow us to leverage state-of-the-art platforms to detect, diagnose and deliver therapeutics, keeping patient care at the center of our mission.”

The Brockman Centennial Tower is expected to open next year in the Texas Medical Center. Spanning more than 1 million square feet, it will house 400 patient beds, an expanded emergency department, new operating rooms and a rooftop garden. It will be connected to Houston Methodist's flagship Paula and Joseph C. “Rusty” Walter III Tower, which opened in 2018. The Centennial Tower was estimated to cost $1.4 billion when announced in 2022.

In addition to the news of the Brockman gift, Houston Methodist also announced this month that it has launched the Houston Methodist Center for Cell and Gene Therapy and tapped an internationally recognized scientist as its leader.

The new center is focused on discovering and developing innovative and cost-effective therapies for a variety of congenital and acquired diseases, including cancer, HIV and cardiovascular disease.

Dr. Malcolm Brenner has been named as the center's inaugural leader and will assume the role starting in October. He will work alongside scientists and support staff from Baylor College of Medicine and Texas Children's Hospital.

Brenner is a professor of pediatrics, medicine, molecular and human genetics and translational biology at Baylor College of Medicine. He is known for making early advances in using bone marrow transplantation as a form of cell therapy and in engineered immune-cell treatments for cancer and infections, according to a release from Houston Methodist.

“Malcolm Brenner is a pioneer in the field of cell and gene therapy and is uniquely qualified to lead Houston Methodist’s research efforts in this field,” Chang added. “His vision and leadership will play a pivotal role in advancing our work in this space.”

Report: Houston reclaims top 10 ranking among America's best cities

Houston has made a triumphant return to America's 10 best cities for 2026, certifying the city is a cornerstone of the country's growth and economic prosperity.

Houston ranks No. 9 nationwide in the annual "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy. Each year, the report ranks the relative qualities of livability, cultural "lovability," and economic prosperity in 393 American cities with metropolitan populations of 500,000 or more.

Dallas surpassed H-Town as the No. 8 best city in America, and the Lone Star State boasts a strong presence among the top 25. Austin and San Antonio, respectively, were named the 11th and 24th best American cities this year.

Previously, Houston was dubbed the 13th best American city in 2025, down from its No. 10 ranking in the 2024 report.

Rather than profiling each individual city like in past reports, the 2026 edition focuses on regional and state prosperity. Texas' economic dominance is second only to Florida's, and the state's growth is solidified by the Dallas-Houston-Austin "triangle," where each metro has its own distinct economic identity, but when combined "form one of the most formidable regional economies in the world."

"In our 2026 survey, Dallas ranks third nationally as the place Americans believe offers the best job opportunities, Austin fifth, and Houston seventh," the report's author wrote. "That concentration of perceived economic opportunity in a single state is unmatched, and the GDP data confirms it isn’t just perception."

After being named one of the best places to start a business or a career earlier in 2026, Houston has continued to punch above its weight with its success in tourism, education, and housing growth.

Overall, the report found a correlation between a city's population growth and its latest ranking, with bigger cities appearing higher up on the list. The top three best American cities — New York, Los Angeles, and Chicago — are coincidentally the three largest metros, while Dallas and Houston are the fourth and fifth largest but appear eighth and ninth on the list.

"Scale compounds at the large city level — more people generate more economic activity, more cultural infrastructure, more employer presence, which attracts more people," the report said.

The top 10 best cities in America for 2026 are:

  • No. 1 – New York
  • No. 2 – Los Angeles
  • No. 3 – Chicago
  • No. 4 – Miami
  • No. 5 – San Francisco
  • No. 6 – Seattle
  • No. 7 – Las Vegas
  • No. 8 – Dallas
  • No. 9 – Houston
  • No. 10 – Boston
