Anyone can die of sepsis. The number one killer in hospitals has a reputation for felling the infirm and elderly, but while the immunocompromised are at highest risk, sepsis isn’t that selective.

Take 12-year-old Rory Staunton. In 2012, the healthy boy scratched his arm diving for a ball in gym class at his school in Jackson Heights, NY. Bacteria entered his arm through the cut and he died days later of septic shock.

His story is not unique. Physician Sarma Velamuri saw this firsthand in his internal medicine practice at St. Luke’s Health Center and his residency at Baylor, both in Houston. But it really struck home when he watched helplessly as a friend’s 22-year-old daughter lost her life to sepsis. He had to tell his friend that she would not be coming home.

“There are 300,000-plus people a year who die of sepsis,” says Velamuri. “It’s important that people understand it’s not just those who are most susceptible to infections.”

This fact is not only unfortunate, but preventable. And that’s why Velamuri, who describes himself as “a recovering hospitalist,” co-founded Luminare in 2014. A full-time CEO since 2017, Velamuri, who runs the company with co-founder and CTO Marcus Rydberg, is based in the TMC Innovation Factory.

“Because of the complex workflows in hospitals, sometimes it takes 10 people to get the patient the care they need,” Velamuri explains.

And because of the pervasiveness of sepsis, it’s important to screen every patient who enters an institution before it gets to that point.

Luminare’s technology allows nurses, who are notoriously spread thin, to automatically screen patients in 10 seconds using 50 different parameters.

“We’re looking at a vast amount of data simultaneously,” says Velamuri. “We’re not generating any new data, we’re taking data that exists and shining a light on it.”

In 2020, the technology found a new application when Velamuri and his team created a version of Luminare that helped with the hospital workflow surrounding COVID PCR testing and vaccine management. Since then, it has also been used to help identify and treat monkeypox.

Though Velamuri says he doesn’t want to distract Luminare from its goal of making sepsis the number-two killer in hospitals, he is also aware that his technology can be instrumental in identifying and treating patients at risk for countless other maladies, including heart failure and stroke, and even helping with oncology workflows.

Velamuri says that his team is Luminare’s biggest strength, far more than the AI that they have designed.

“I have this saying that AI is a great servant but a terrible master. It doesn’t solve the problem,” says Velamuri.

Though the company is distributed as far afield as Stockholm, about half of its people live and work in Houston. Of the company’s placement in TMC’s Innovation Factory, Velamuri says, “They’ve been tremendous partners to us. The company would not be as successful today without their supportive partnership.” Not least of that is working with in the same space as other founders who can share their expertise as easily as a trip to the coffee machine.

And the company is growing quickly. Last year, Luminare participated in Cedars-Sinai’s accelerator program. Thanks to that partnership, the hospital is now using Luminare’s technology for sepsis screening. The team is working to partner with even more large hospital systems on solutions for one of the health industry’s biggest problems. And data that shows that Luminare can be the path to preventing death from hospitals’ most prolific killer.

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
