By one measure, Houston could be considered the startup capital of Texas.

A new study by personal finance website LendingTree shows the Houston metro area experienced a 37.4 percent jump in new-business applications from 2019 to 2020. That was the highest growth rate among Texas’ six biggest metro areas and the 20th highest growth rate among the 100 U.S. metro areas with the most new-business applications in 2020.

In 2019, the Houston area racked up 85,998 new-business applications, according to U.S. Census Bureau data cited by LendingTree. A year later, the number of applications in the region soared to 118,183. The data measures applications for nine-digit employer identification numbers (EINs), which the IRS uses to track businesses for tax purposes. An EIN is similar to a person’s Social Security number.

“The pandemic has created so much financial chaos for so many people, and that uncertainty surely spurred many Americans to take the plunge,” says Matt Schulz, chief credit analyst at LendingTree.

“Some folks did it out of necessity because of income or job losses,” he adds. “Some folks did it to feel more secure, as the idea of relying on one source of income just didn’t make sense anymore for a lot of people. Others likely did it because they’d wanted to for years but never felt the time was right.”

Across the U.S., the retail sector witnessed the heftiest increase (59.7 percent) in new-business applications from 2019 to 2020.

“So many companies have made it so easy to sell online that people feel good about taking the plunge,” Schulz says. “Setting up an online store is generally simpler, quicker and less expensive than ever, so the barriers to entry that once scared potential entrepreneurs away from opening a new store aren’t the obstacles that they once were.”

Memphis, Tennessee, topped the LendingTree list. The metro area saw a 77.9 rise in new-business applications from 2019 to 2020.

Elsewhere in Texas:

  • Dallas ranked 37th nationally and second in Texas, with a 29 percent increase in new-business applications.
  • San Antonio ranked 62nd nationally and third in Texas, with an 18 percent increase in new-business applications.
  • McAllen ranked 77th nationally and fourth in Texas, with a 13.3 percent increase in new-business applications.
  • Austin ranked 78th nationally and fifth in Texas, with a 13.2 percent increase in new-business applications.
  • El Paso ranked 79th nationally and sixth in Texas, with an 11.9 percent increase in new-business applications.

Surprising share of Houstonians saddled with $10,000 or more in credit card debt

fully charged

You hear that noise, Houston? It's the sound of your bank account screaming under the weight of the heavier debt load you're shouldering.

A report released by personal finance platform LendingTree shows Houston ranks tenth among the 100 largest U.S. metro areas for the share of people with credit card balances totaling at least $10,000.

In an aggressive jump, Houston climbed from No. 32 two years ago to No. 10 this year. According to LendingTree, 20 percent of cardholders in the metro have credit card debt of at least $10,000, and 1.6 percent have credit card debt of at least $50,000.

Elsewhere in Texas, Austin jumped 20 spots in the ranking to sixth in the nation, compared with its 26th-place showing in LendingTree's 2019 report. Some 20.8 percent of Austinites show credit card balances totaling at least $10,000. LendingTree says 1.7 percent of cardholders in Austin owe at least $50,000.

Meanwhile, Dallas-Fort Worth moved from No. 33 to No. 18. Today, 19.2 percent of cardholders in the metro have debt totaling at least $10,000 and 1.5 percent have credit card debt totaling at least $50,000.

San Antonio rose from No. 27 to No. 26. There, 18.4 percent of cardholders have credit card debt of $10,000 or more and 1.2 percent have credit card debt of $50,000 or more.LendingTree offers perhaps a partial explanation for the increase in five-digit credit card balances among Texas metros: "While the saying goes that 'everything is bigger in Texas,' that hasn't traditionally been the case with salaries in the Lone Star State. The big metros in Texas have generally trailed behind the big coastal metros in that measure."

Bridgeport, Connecticut, holds the No. 1 spot for the largest share of cardholders (24.3 percent) with at least $10,000 in debt.------

UH, Baylor researchers make breakthrough with new pediatric leukemia treatment device

childhood cancer

A team of Houston researchers has developed a new microfluidic device aimed at making treatments safer for children with hyperleukocytosis, a life-threatening hematologic emergency often seen in patients with leukemia.

Dr. Fong Lam, an associate professor of pediatrics at Baylor College of Medicine and a pediatric intensive care physician at Texas Children’s Hospital, partnered with Sergey Shevkoplyas, a professor of biomedical engineering at UH, on the device that uses a large number of tiny channels to quickly separate blood cells by size in a process called controlled incremental filtration, according to a news release from UH.

They tested whether performing cell separation with a high-throughput microfluidic device could alleviate the limitations of traditional conventional blood-filtering machines, which pose risks for pediatric patients due to their large extracorporeal volume (ECV), high flow rates and tendency to cause significant platelet loss in the patient. The results of their study, led by Mubasher Iqbal, a Ph.D. candidate in biomedical engineering at UH, were published recently in the journal Nature Communications.

“Continuously and efficiently separating leukocytes from recirculating undiluted whole blood — without device clogging and cell activation or damage — has long been a major challenge in microfluidic cell separation,” Shevkoplyas said in a news release. “Our study is the first to solve this problem.”

Hyperleukocytosis is a condition that develops when the body has an extremely high number of white blood cells, which in many cases is due to leukemia. According to the release, up to 20 percent to 30 percent of patients with acute leukemia develop hyperleukocytosis, and this places them at risk for potentially fatal complications.

The new device utilizes tiny channels—each about the width of a human hair—to efficiently separate blood cells through controlled incremental filtration. According to Lam, the team was excited that the new device could operate at clinically relevant flow rates.

The device successfully removed approximately 85 percent of large leukocytes and 90 percent of leukemic blasts from undiluted human whole blood without causing platelet loss or other adverse effects. It also operates with an ECV that’s about 1/70th of conventional leukapheresis machines, which makes it particularly suitable for infants and small children.

“Overall, our study suggests that microfluidics leukapheresis is safe and effective at selectively removing leukocytes from circulation, with separation performance sufficiently high to ultimately enable safe leukapheresis in children,” Shevkoplyas said in the release.

Greentown Labs adds 5 new Houston startups to climatetech incubator

Going Green

Greentown Labs announced that it added five startups to its Houston community in Q1 of 2025.

The companies are among a group of 19 that joined the climatetech incubator, which is co-located in Houston and Boston, in the same time period. The companies that joined the Houston-based lab specialize in a number of "green" applications, from converting plastic waste into sustainable materials to developing energy-storage solutions.

The new Houston members include:

  • Concept Loop, a project of Pakistan-based Innova8e Inc., aims to repurpose post-industrial and post-consumer plastic waste into sustainable building materials.
  • GeoFuels, a Sugar Land-based company that produces hydrogen by using baseload geothermal power and methane pyrolysis.
  • PLASENE, a Houston-based company with an innovative platform that converts plastic waste into liquid fuel and low-carbon hydrogen through its proprietary catalysts and modular, scalable, pre-engineered units platform. The company was named to Greentown's ACCEL Year 3 cohort earlier this year.
  • RepAir Carbon, an Israeli company with a fully electric, zero-heat carbon-removal technology that consumes minimal energy, operates without liquids or solvents, and produces no hazardous materials or waste.
  • RotorVault from Pasadena, California, is commercializing energy-storage and load-following solutions that are containerized, modular, and field-deployable systems built on flywheel technology.

Fourteen other companies will join Greentown Boston's incubator. See the full list here.

PLASENE and five other new members—Thola, Respire Energy, Andros Innovations, FAST Metals and Tato Labs—join Greentown Labs through its most recent Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, cohort. ACCEL, which works to advance BIPOC-led startups in the climatetech space, announced its third cohort last month.

Houston startup unveils its innovative leather alternative at the rodeo

sustainable fashion

Last month’s Houston Livestock Show and Rodeo stirred up another rootin’ tootin’ time for Houstonians and beyond.

But before the annual event galloped into the sunset, there were quite a few memorable innovations on display, with one notably coming from Rheom Materials.

The Houston-based pioneer of next-generation materials presented its scalable, bio-based alternative known as Shorai, a 93 percent bio-based leather, through two custom, western-inspired outfits that showed off cowboy flair through a sustainable lens.

“I'm a Houstonian, I love the rodeo,” Megan Beck, Rheom’s business development manager, recalls. “We're sitting there talking about it one day and we're like, ‘Okay, we've got to do something with this leather to show people how good it can look in apparel, how easy it is to wear.’”

Buoyed by the idea that their materials are meant to “change your impact, not your life,” Rheom captured the real-life energy of their bio-leather outfits under the rodeo’s neon lights in a short commercial video and photo shoot with models donning the samples, while dancing and enjoying the festivities. Rheom created a skirt, a leather jacket, and then a leather top for the look.

“Houston is such a vibrant city,” Beck says. “There's so much innovation here. I think the rodeo is just a really, really great example of that. And so we wanted to take this opportunity to take some of these garments out there and go on the slide, go on some of the rides, go into the wine garden and go dancing, because if you've ever felt some of the materials in the market in this space, they're very stiff, you can't really move in them, they're a little fragile, they kind of fall apart.”

Not only do the models in the video look fashionable, but they also look comfortable, and the leather looks natural and supple. And to the naked eye, Shorai appears to be like the leather most wearers are accustomed to.

“What we really wanted to showcase in this is the energy and the movement of the leather, and to show people how good it can look in apparel, and how easy it is to wear, which I think we were able to accomplish,” Beck says.

Next up, Beck says Rheom wants to scale production of Shorai, the Japanese word for “future,” at a competitive price point, while also reducing its carbon footprint by 80 percent when compared to synthetic leather. According to Beck, Rheom plans to see Shorai products come to market sometime this year.

“We have companies globally right now that are testing materials, that are prototyping, that are making garments, making handbags and footwear, and making eyewear because we have a plastic, as well,” Beck says. “So, this year, I do believe we'll start seeing those products actually come to market, which is very, very exciting for us.”

And with their large-scale production partner already set up for Shorai, Rheom plans to start its first production run of the product soon.

“In April, we'll actually be starting our first production run,” Beck says. “We'll be doing it at full scale, full width, and a full run of materials. So over the next five years, we're only going to just try to increase that capacity.”
