A Houston-based medical device company born out of the Texas Medical Center has closed its series A round of funding.

Ictero Medical's oversubscribed $6 million round was led by MedTex Ventures, S3 Ventures, and an undisclosed strategic investor, according to a news release. The company's novel cryoablation system was designed to treat high-risk gallstone disease patients and provide a less invasive and lower risk alternative to gallbladder removal surgery — something over 1 million Americans undergo annually.

“Our technology provides an immediate solution for critically ill patients who currently have no good treatment options, and also has the potential to benefit healthier patients who want to avoid surgery,” says Ictero Co-Founder and CEO Matthew Nojoomi in the release.

Recently, Ictero Medical entered into a partnership with Houston medical device development firm Biotex. The collaboration provides the company with engineering resources and in-house manufacturing tools. Ictero also received capital support from MedTex Ventures through its Biotex Medical Device Fund.

“We are excited about working with the Ictero team to advance its technology, which we believe can significantly improve patient experiences and outcomes by providing a non-surgical alternative to treating gallbladder disease,” says Biotex CEO Ashok Gowda in the release.

The fresh funds will be put toward further product development and initial clinical testing.

“MedTex Ventures is enthusiastic about Ictero’s novel cryoablation technology and its potential to solve the unmet need of inoperable patients with gallbladder disease,” says John Fichthorn, CIO of MedTex Ventures, in the news release. “Equally important is the team. We believe the combination of Ictero and Biotex’s technical capabilities, alongside the support from key investors with commercial experience, such as S3 Ventures, position the company for long term success.”

Ictero was founded as a part of the Texas Medical Center’s Biodesign Fellowship program in 2018. Since launch, the company has received a Phase I NSF grant and closed a $1 million seed round co-led by the Texas Medical Center Venture Fund and Texas HALO Fund.

“Ictero is at the forefront of pioneering cryotherapy for gallstone disease, and S3 Ventures is excited about the potential for Ictero’s novel solution to rapidly bring an impactful outcome to patients,” says Kim Rodriguez, venture partner at S3, in the release. “Our research suggests a substantial opportunity to help patients suffering from gallstone disease who are dependent on drainage catheters or too sick for surgery. We are joining a solid investment syndicate in supporting a very capable team.”

3 Houston innovators to know this week

who's who

Editor's note: In the week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — data science, consumer tech, and medical device innovation — recently making headlines.

When the pandemic hit, the team at Mercury Data Science knew data was going to have a huge role to play. Last fall, MDS released an AI-driven app designed to help researchers unlock COVID-19-related information tucked into biomedical literature. The app simplified access to data about subjects like genes, proteins, drugs, and diseases.

Now, a year into the coronavirus pandemic, the company is applying this technology to areas like agricultural biotech, in which the platform enables researchers to sift through literature to dig up data about plant genetics, says Angela Holmes, chief operating officer at MDS. The lack of gene-naming standards in the world of plants complicates efforts to search data about plant genetics, she says.

The platform's ability to easily ferret out information about plant genetics "allows companies seeking gene-editing targets to make crops more nutritious and more sustainable as the climate changes to have a rapid way to de-risk their genomic analyses by quickly assessing what is already known versus what is unknown," Holmes says.

In the process of building a medical device company called Visualase and exiting it to Medtronic for over $100 million, Ashok Gowda learned a lot. And, over the past two decades, he's been sharing that knowledge and expertise of his and his team to medtech companies of all stages at Houston-based BioTex.

"Ultimately we built a nice infrastructure by supporting (the Visualase) spin out," Gowda tells InnovationMap. "And we learned a lot about not just product development, but about commercializing and creating a new market that may not exist. And we had some really good, experienced commercial folks we had hired on the Visualase side. I just think it's a good learning lesson that you can't really teach this stuff — you gotta experience it really to understand." Click here to read more.

Rachel Moncton has lived all over the world in her career at fitness and wellness-focused consumer tech company, ClassPass — and her latest assignment has been standing up the company's fourth domestic office right here in Houston, Texas.

On last week's episode of the Houston Innovators Podcast, Moncton shares how Houston as a hub offers the growing company a chance to be a big fish in a small consumer tech pond.

"I get a lot of people saying, 'Houston? That's an interesting choice and not what we'd expect,'" Moncton says. "But that's one of the things we like about it. There's a good startup scene here but not a million different consumer tech companies, so it's nice that we are able to make a bit of a splash." Click here to read more.

Houston medtech company helping to get health care innovations from idea to exit

future of health care

Founding a health tech company is a process unlike any other startup. From the regulatory phase to clinical trials, health tech innovators face a long runway from idea to market, but a Houston-based organization has been working for over 20 years to help make that take-off process run more smoothly.

Ashok Gowda founded BioTex Inc. in 1998, and at the time he was finishing up his PhD at Texas A&M University and wanted a company to support his own health tech ideas, including Visualase Inc. After the real-time tissue monitoring system exited to Medtronic for over $100 million, Gowda realized he can put everything he had learned from taking Visualase from idea to exit and apply it to new medical device innovation.

"Ultimately we built a nice infrastructure by supporting (the Visualase) spin out," Gowda tells InnovationMap. "And we learned a lot about not just product development, but about commercializing and creating a new market that may not exist. And we had some really good, experienced commercial folks we had hired on the Visualase side. I just think it's a good learning lesson that you can't really teach this stuff — you gotta experience it really to understand."

At this point, BioTex has worked with over 40 medical device and health tech companies in some capacity — from early prototyping and research and development to FDA approval, manufacturing, and even distribution. With a staff of around 50 and an 18,000-square-foot facility just south of the Texas Medical Center, BioTex can support around 10 to 15 clients at a time — usually in the medical device sector but across specialties from neurosurgery, cardiology, radiology, urology, gynecology, orthopedics, anesthesia, and more.

"It's a pretty broad experience, and I think it gives us a good perspective when we talk to a physician or a group of entrepreneurs — we can pretty easily get up to speed or understand the problem because we've usually worked in this space before," Gowda says.

With the infrastructure BioTex has in place, Gowda says he still sees one aspect of health tech development that needs more attention.

"There are obviously a lot of really good ideas here and a lot of push to try to get those ideas to market. But, there are very few of those that have gotten to market and to become commercial products," Gowda says. "It does require a lot of capital to bring medical technology to market — and it usually requires a lot of time as well."

Health tech founders facing the long runway of development usually need enough funds to support them through the process — as well as the know how and support BioTex has.

"We think we solve few of these problems with our in-house expertise, but the one that we are now focused on and trying to solve is the funding gap," Gowda says. "When we see a good idea or a technology, we want to help them get that to market and not let that lack of funding be an impediment."

At Houston Exponential's second annual HX Capital Summit, four Houston entrepreneurs turned investors discussed their lessons learned. Getty Images

Here's what startups can learn from Houston exits

Success stories

One way to evaluate a city's innovation ecosystem is by the number of successful exits they've had. From startups being acquired by big companies to bringing in a private equity partner, exits can put a city on the map.

Houston has quite a few exits under its belt, and some of those entrepreneurs have stayed in town to fund future success stories. At Houston Exponential's second annual HX Capital Summit, four entrepreneurs discussed their exits, providing key lessons learned for entrepreneurs.

Houston has some perks. 

One thing moderator Samantha Lewis, director at the GOOSE Society of Texas, asked each panelist was what made each entrepreneur start their companies in Houston — and furthermore, what made them stay here after their successful exit.

Panelist Ashok Gowda co-founded and served as COO at Visualase Inc., a real-time tissue monitoring system that exited to Medtronic for over $100 million. He now leads Biotex, a Houston-based medical technology investment firm and accelerator, as president and CEO.

For Gowda, Houston was obviously a key market for med tech, but it provided something even more once he reached the commercialization phase of a product.

"From a commercial standpoint, once the technology became commercial, it was an ideal location," Gowda says. "We were traveling all across the US, and it was a nice hub. We're right in the center of the country, and you can get to either coast very quickly."

The panel also agreed that the quality of life in Houston played a major role in settling down.

You might need to rethink your executive team. 

The panel full of venture capitalists of course touched on the ability to fundraise in Houston, as each panelist had been on both sides of the table. For Gowda, it's pretty simple.

"If you're struggling to raise money, you either have a bad idea or the wrong team," he says, adding that if you really believe in your idea, take a good hard look at who's at the leadership level of your team.

Talent is still a challenge in Houston.

Of course, if you do identify a problem within your team, finding the right leader for your technology might be difficult in Houston.

Keith Kreuer, who was also on the panel, is principal at RedHouse Associates, a group of angel investors that invest like a find would, but without having a fund. Between Kreuer and his team, they were involved in 10 startups before forming the investment group.

"We could find developer and sales talent here, but to get to that higher executive talent, we had to go out to other places," Kreuer says.

However, not all of the panelists agreed that talent was a major challenge they faced. Some noted that they got lucky with the talent they found.

Don Kendall, CEO of Kenmont Capital Partners, came to Houston to run a power company and family office. He turned $100,000 into $1.6 billion and now is a member of GOOSE.

"We had no problem getting the engineering talent," Kendall says. "We really found Houston to be a good environment, and it's only just continued to improve."

Playing to Houston's strengths might be key to success.

For Gray Hall, managing director at Austin-based BuildGroup, which focuses on writing big checks to a small amount of software startups, he knew how to play to his company's and Houston's strengths.

Hall previously served as CEO of AlertLogic, which had a private equity exit in 2013, and Hall stayed on until 2018 as the company continued to grow. He also co-founded Veracenter, which had a strategic exit after growing to $80 million in annual revenue.

"The common theme across both companies and why we were able to grow is real simple: Customer and people," Hall says.

Houston might be one of the country's best kept secrets when it comes to midmarket activity, Hall notes — midmarket companies being defined as those with $50 million to $1 billion in revenue.

"What Houston doesn't get enough credit for is the midmarket in Houston, which I think is tremendous," Hall says. "It's as strong as anywhere else in the country."

AlertLogic was able to tap into this midmarket to quickly grow its client base.

Something else that differentiates Houston from other cities is its culture, which is less focused on the glitz and glam and more focused on hard work.

"Engage with people that have a credible story and a credible plan to solve a problem," he says.

Houston is growing. 

One thing each of the entrepreneurs agreed on is that the city is only growing its resources and quality of startups.

"I see Houston as sort of a startup in the startup world," Kreuer says. "And, what we're trying to do is grow and catch up to the West Coast and the East Coast, but I think Texas as a whole is going to be pretty powerful, and Houston is going to be a central part of that mainly because we have the markets here, and the people in the area and the talent to do that."

As Houston's success stories become more frequent, this provides an avenue for more entrepreneurs turned investors.

"When you've done it before, you've learned the lessons, and you feel like you can do it again and again," Gowda says. "That's what we're trying to do. You see all the possibilities here."

NASA revamps Artemis moon landing program by modeling it after Apollo

To the moon

NASA is revamping its Artemis moon exploration program to make it more like the fast-paced Apollo program half a century ago, adding an extra practice flight before attempting a high-risk lunar landing with a crew in two years.

The overhaul in the flight lineup came just days after NASA’s new moon rocket returned to its hangar for more repairs, and a safety panel warned the space agency to scale back its overly ambitious goals for humanity’s first lunar landing since 1972.

Artemis II, a lunar fly-around by four astronauts, is off until at least April because of rocket problems.

The follow-up mission, Artemis III, had been targeting a landing near the moon’s south pole by another pair of astronauts in about three years. But with long gaps between flights and concern growing over the readiness of a lunar lander and moonwalking suits, NASA’s new administrator Jared Isaacman announced that mission would instead focus on launching a lunar lander into orbit around Earth in 2027 for docking practice by astronauts flying in an Orion capsule.

The new plan calls for a moon landing — potentially even two moon landings — by astronauts in 2028.

“Everybody agrees. This is the only way forward,” Isaacman said.

The hydrogen fuel leaks and helium flow problems that struck the Space Launch System rocket on the pad at NASA's Kennedy Space Center in February also plagued the first Artemis test flight without a crew in 2022.

Another three-year gap was looming between Artemis II and the moon landing by astronauts as originally envisioned, Isaacman said.

Isaacman stressed that “it should be incredibly obvious” that three years between flights is unacceptable. He'd like to get it down to one year or even less.

Isaacman, a tech billionaire who bought his own trips to orbit and performed the world’s first private spacewalk, took the helm at NASA in December.

During NASA’s storied Apollo program, he said, astronauts’ first flight to the moon was followed by two more missions before Neil Armstrong and Buzz Aldrin landed on the moon. What's more, he added, the Apollo moonshots followed one another in quick succession, just as the earlier Projects Mercury and Gemini had rapid flight rates, sometimes coming just a few months apart.

Twenty-four Apollo astronauts flew to the moon from 1968 through 1972, with 12 of them landing.

“No one at NASA forgot their history books. They knew how to do this," Isaacman said. “Now we're putting it in action.”

To pick up the pace and reduce risk, NASA will standardize its Space Launch System rockets moving forward, Isaacman said. These are the massive rockets that will launch astronauts to the moon aboard Orion capsules. At the same time, Elon Musk's SpaceX and Jeff Bezos' Blue Origin are speeding up their work on the landers needed to get the astronauts from lunar orbit down to the surface.

Isaacman said next year will see an Orion crew rendezvousing in orbit around Earth with SpaceX's Starship, Blue Origin's Blue Moon or both landers. It's similar to the methodical approach that worked so well during Apollo in the late 1960s, he noted. Apollo 8, astronauts' first flight to the moon, was followed by two more missions before Armstrong and Aldrin aimed for the lunar surface.

“We should be getting back to basics and doing what we know works,” he said.

The Aerospace Safety Advisory Panel recommended that NASA revise its objectives for Artemis III “given the demanding mission goals.” It’s urgent the space agency do that, the panel said, if the United States hopes to safely return astronauts to the moon. Isaacman said the revised Artemis flight plan addresses the panel's concerns and is supported by industry and the Trump administration.

Booming Houston suburb launches innovation grant to attract startups

innovation incentive

Think you’ve got a burgeoning startup? Consider moving it to southwest Houston. The City of Sugar Land announced the Sugar Land Starts Innovation Fund last week to support companies that move jobs to the area.

“The Sugar Land Starts Innovation Fund is designed to support companies that are ready to grow and make a meaningful, long-term commitment to our community,” Colby Millenbruch, business recruitment manager for the City of Sugar Land, said in a news release. “By focusing on revenue-generating startups and performance-based incentives, we are creating a clear pathway for innovative companies to scale while reenergizing existing office space.”

The performance-based, non-equity dilutive grant program is open to companies that demonstrate at least $250,000 in generated revenue or $500,000 in institutional backing from a bank or venture capital firm. They must commit to hiring or relocating at least three employees in Sugar Land for a minimum of three years and at an average salary of $61,240. Compliance will be verified through Texas Workforce Commission reporting.

The fund builds off the Sugar Land Plug and Play partnership to turn the city into an innovative technology hub.

Collaboration with the Silicon Valley-based startup incubator and accelerator on a physical location in southwest Houston has supported 22 startups and has raised $6.5 million in capital since it officially launched in Sugar Land last March. Companies located at the Sugar Land Plug and Play include Synaps, a browser-based design platform for architects, and Intero Biosystems, which produces miniature human organs for preclinical drug development.

In addition to direct funding and business space, both the new grant and the overall Plug and Play project facilitate meetings with Houston-area businesses like CenterPoint Energy.

This should not only bring new industries to Sugar Land, but also allow existing companies to expand outward as technological investors to create a web of new progress.

“This investment is about more than technology. It’s about creating an environment where innovation can take root, grow, and deliver lasting value for the Sugar Land community,” David Steele, director of Texas at Plug and Play, added in the release. “Sugar Land is setting itself apart by taking a long-term view, investing in founders, partnerships, and technologies that will define the next chapter of growth. We’re proud to partner with the city in building an innovation ecosystem that benefits both entrepreneurs and the broader community.”

Income study shows $100,000 salary goes further in Houston in 2026

Money Talk

A 2026 income study has good news for big earners in Houston: A six-figure salary goes further than it did last year.

A Houston resident's $100,000 salary is worth $84,840 after taxes and adjusted for the local cost of living, according to the new financial analysis from SmartAsset. That's about $1,500 more than Houstonians were bringing home last year.

The 2026 take-home pay is about 8 percent higher than it was in 2024, when the same salary had an adjusted value of $78,089.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities. The figure was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services). Cities were then ranked based on where a six-figure salary is worth the least after applicable taxes and cost of living adjustments.

Houston ranked No. 60 in the overall ranking of U.S. cities where $100,000 is worth the least. If the rankings were flipped and the cities were ranked based on where $100,000 goes the furthest, that places Houston in the No. 10 spot nationwide.

Manhattan, New York remains the No. 1 city where a six-figure salary is worth the least. A Manhattan resident's take-home pay is only worth $29,420 after taxes and adjusted for the cost of living, which is 3.10 percent lower than it was in 2025.

SmartAsset determined Manhattan has a 29.7 percent effective tax rate on six-figure salaries. Meanwhile, the effective tax rate on a $100,000 salary in Texas (based on the eight cities examined in the report) is 21.1 percent. It's worth highlighting that New York implements a statewide graduated-rate income tax from 4-10.90 percent, whereas Texas is one of only eight states that don't tax residents' income.

Oklahoma City, No. 69, is the U.S. city in the report where a $100,000 salary stretches the furthest. A six-figure salary is worth $91,868 in 2026, up from $89,989 last year.

This is the post-tax value of a $100,000 salary in other Texas cities, and their ranking in the report:

  • Plano (No. 27): $72,653
  • Dallas (No. 47): $80,103
  • Austin (No. 53): $82,446
  • Lubbock (No. 59): $84,567
  • San Antonio (No. 62): $86,419
  • El Paso (No. 67): $90,276
  • Corpus Christi (No. 68): $91,110
According to the report, getting some "financial breathing room" by making six-figures really depends on where someone lives and what their lifestyle is. For residents living in the 42 states that levy some amount of income tax, their take-home pay dwindles further."And depending on how taxes are filed, reaching a $100,000 income may push a household from the 22 percent to 24 percent marginal tax bracket," the report's author wrote. "Meanwhile, locations with high costs across housing and everyday essentials may be less forgiving to a $100,000 income."
