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."

With boost from Houston, Texas is the No. 1 state for economic development

governor's cup

Texas is on a 14-year winning streak as the top state for attracting job-creating business location and expansion projects.

Once again, Texas has claimed Site Selection magazine’s Governor’s Cup. This year’s honor recognizes the state with the highest number of economic development projects in 2025. Texas landed more than 1,400 projects last year.

Ron Starner, executive vice president of Site Selection, calls Texas “a dynasty in economic development.”

Among metro areas, Houston lands at No. 2 for the most economic development projects secured last year (590), behind No. 1 Chicago and ahead of No. 3 Dallas-Fort Worth.

In praising Houston as a project magnet, Gov. Greg Abbott cites the November announcement by pharmaceutical giant Lilly that it’s building a $6.5 billion manufacturing plant at Houston’s Generation Park.

“Growth in the Greater Houston region is a great benefit to our state’s economy, a major location for foreign direct investment and key industry sectors like energy, aerospace, advanced manufacturing, and life sciences,” Abbott tells Site Selection. “Houston is also home to one of the largest concentrations of U.S. headquarters for companies from around the world.”

In 2025, Fortune ranked Houston as the U.S. city with the third-highest number of Fortune 500 headquarters (26).

Texas retained the Governor’s Cup by gaining over 1,400 business location and expansion projects last year, representing more than $75 billion in capital investments and producing more than 42,000 new jobs.

Site Selection says Texas’ project count for 2025 handily beat second-place Illinois (680 projects) and third-place Ohio (467 projects). Texas’ number for 2025 represented 18% of all qualifying U.S. projects tracked by Site Selection.

“You can see that we are on a trajectory to ensure our economic diversification is going to inoculate us in good times, as well as bad times, to ensure our economy is still going to grow, still create new jobs, prosperity, and opportunities for Texans going forward,” Abbott says.

Houston e-commerce giant Cart.com raises $180M, surpasses $1B in funding

fresh funding

Editor's note: This article has been updated to clarify information about Cart.com's investors.

Houston-based commerce and logistics platform Cart.com has raised $180 million in growth capital from private equity firm Springcoast Partners, pushing the startup past the $1 billion funding mark since its founding in 2020.

Cart.com says it will use the capital to scale its logistics network, expand AI capabilities and develop workflow automation tools.

“This investment will strengthen our balance sheet and provide us with the flexibility to accelerate our strategic priorities,” Omair Tariq, CEO of Cart.com, said in a news release. “We’ve built a platform that combines commerce software with a scaled logistics network, and we’re just getting started.”

In conjunction with the funding, Springcoast executive-in-residence Russell Klein has been appointed to Cart.com’s board of directors. Before joining Springcoast, he was chief commercial officer at Austin-based Commerce.com (Nasdaq: CMRC). Klein co-led Commerce.com’s IPO, led the company’s mergers-and-acquisitions strategy and played a key role in several funding rounds.

“The team at Cart.com has demonstrated excellence in their ability to scale efficiently while continuing to innovate,” Klein said. “I’m excited to join the board and support the company as it expands its AI-driven capabilities, deepens enterprise relationships, and further strengthens its position as a category-defining commerce and fulfillment platform.”

Before this funding round, Cart.com had raised $872 million in venture capital and reached a valuation of about $1.6 billion, according to CB Insights. With the new funding, the startup has collected over $1 billion in just six years.

This is the income required to be a middle class earner in Houston in 2026

Cashing In

A new study tracking the upper and lower thresholds for middle class households across the nation's largest cities has revealed Houstonians need to make at least a grand more than last year to maintain their middle class status this year.

According to SmartAsset's just-released annual report, "What It Takes to Be Middle Class in America – 2026 Study," Houston households need to make anywhere from $42,907 to $128,722 to qualify as middle class earners this year.

Compared to 2025, Houstonians need to make $1,153 more per year to meet the minimum threshold for a middle class status, whereas the upper bound has stretched $3,448 higher. The median income for a Houston household in 2024 was $64,361, the study added.

SmartAsset's experts used 2024 Census Bureau median household income data for the 100 biggest U.S. cities and all 50 states and determined middle class income ranges by using a variation of Pew Research's definition of a middle class household, stating the salary range is "two-thirds to double the median U.S. salary."

In the report's ranking of the U.S. cities with the highest household incomes needed to maintain a middle class status, Houston ranked No. 80.

In the report's state-by-state comparison, Texas has the 24th highest middle class income range. Overall, Texas households need to make between $53,147 and $159,442 to be labeled "middle class" in 2026. For additional context, the median income for a Texas household in 2024 came out to $79,721.

"Often, the expectations that come with the term 'middle class' include reaching home ownership, raising kids, the comfort of modest emergency funds and retirement savings, and the occasional splurge or vacation," the report said. "And as the median household income varies widely across the U.S. depending on the local job market, housing market, infrastructure and other factors, so does swing the bounds on what constitutes a middle class income in America."

What it takes to be middle class elsewhere around Texas

Two Dallas-Fort Worth suburbs – Frisco and Plano – have some of the highest middle class income ranges in the country for 2026, SmartAsset found.

Frisco households need to make between $96,963 and $290,888 to qualify as middle class this year, which is the third-highest middle class income range nationwide.

Plano's middle class income range is the eighth highest nationally, with households needing to make between $77,267 and $231,802 for the designation.

Salary range needed to be a middle class earner in other Texas cities:

  • No. 28 – Austin: between $60,287 and $180,860
  • No. 40 – Irving: between $56,566 and $169,698
  • No. 44 – Fort Worth: between $55,002 and $165,006
  • No. 57 – Garland: between $50,531 and $151,594
  • No. 60 – Arlington: between $49,592 and $148,77
  • No. 61 – Dallas: between $49,549 and $148,646
  • No. 73 – Corpus Christi: between $44,645 and $133,934
  • No. 77 – San Antonio: between $44,117 and $132,352
  • No. 83 – Lubbock: between $41,573 and $124,720
  • No. 84 – Laredo: between $41,013 and $123,038
  • No. 89 – El Paso: between $39,955 and $119,864
