Lounging at Margaritaville Lake Resort at Lake Conroe was just made easier by Rivalry Tech, a Houston-based mobile ordering platform company. Rivalry Tech upgraded poolside ordering with its myEATz. According to a news release, customers can now order food and drinks from the 5 o’Clock Somewhere Bar and Lone Palm Bar via a custom QR code system for each lounge chair and table to increase operational efficiency for the Margaritaville Lake Resort staff.

“We wanted to be sure the rollout of the myEATz mobile ordering platform was helpful to the Margaritaville staff, not a hindrance to their existing process. We created custom QR codes and a color coded map to easily identify where the mobile orders are going,” says Charles Willis, COO of Rivalry Tech, in the release.

Rivalry, which provides mobile ordering at numerous sports stadiums and venues with sEATz, expanded into hospitality this year.

“The Rivalry Tech team helped us to seamlessly implement mobile ordering at Margaritaville Lake Resort. They created the marketing materials, established custom QR codes, uploaded mentors and trained our staff onsite. The whole process has been easy and collaborative,” says Amit Sen, director food and beverage for Margaritaville Lake Resort, in the release.

Houston-based venture capital firm Mercury led Phillidelphia-based SaaS company ReturnLogic's $8.5 million series A funding round, which also had participation from Revolution’s Rise of the Rest Fund, White Rose Ventures, and Ben Franklin Technology Partners. The fresh funding will help the company double its workforce, accelerate product development, and expand Application Programming Interface capabilities, according to a news release.

Founded by CEO Peter Sobotta, Return Logic's SaaS platform, which can be plugged into existing e-commerce platforms, helps to enhance management of returns and prevent the challenging financial impacts of returns.

“While retailers have largely mastered forward logistics to get products into customers hands, the returns process remains an under-addressed, resource-draining problem that eats away at brands’ profits,” says Blair Garrou, managing director of Mercury, in a news release. “ReturnLogic is something entirely new to this market and uniquely built on Peter Sobotta’s deep operational experience in reverse logistics and supply chain management.

"While serving in the U.S. Navy, Peter specialized in reverse logistics and gained extensive expertise in ecommerce operations," Garrou continues. "With Peter at the helm, ReturnLogic’s innovative API-first returns solution is well-positioned to tackle the ever-growing operational returns problem facing retailers. We are excited to partner with Peter and his team as they continue to solve this massive problem for online retailers.”

OpenStax, a tech initiative from Rice University that uploads free learning resources, has announced it will publish the 10th edition of an organic chemistry textbook by Cornell University professor emeritus John McMurry.

“This is a watershed moment for OpenStax and the open educational resources (OER) movement,” says Richard Baraniuk, founder and director of OpenStax, in a news release. “This publication will quickly provide a free, openly licensed, high-quality resource to hundreds of thousands of students in the U.S. taking organic chemistry, removing what can be a considerable cost and access barrier.”

Usually a big expense for organic chemistry students, McMurry, with the support of publisher Cengage, made the decision to offer the latest edition online as a tribute to his son, Peter McMurry, who died in 2019 after a long struggle with cystic fibrosis.

“If Peter were still alive, I have no doubt that he would want me to work on this 10th edition with a publisher that made the book free to students,” McMurry says in the release. “To make this possible, I am not receiving any payment for this book, and generous supporters have covered not only the production costs but have also made a donation of $500,000 to the Cystic Fibrosis Foundation to help find a cure for this terrible disease.”

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
