An innovative Houston company is celebrating a new deal with a global airline.

Cemvita Corp. announced a new offtake arrangement with United Airlines. Cemvita's first full-scale sustainable aviation fuel plant will provide up to 1 billion gallons of SAF to United Airlines. The 20-year contract specifies that Cemvita will supply up to 50 million gallons annually to United.

It's not the first collaboration Cemvita has had with the airline. Last year, United invested in the biotech company, which used the funding to open its Houston pilot plant.

“Since our initial investment last year, Cemvita has made outstanding progress, including opening their new pilot plant – an important step towards producing sustainable aviation fuel,” United Airlines Ventures President Michael Leskinen says in a news release. “United is the global aviation leader in SAF production investment, but we face a real shortage of available fuel and producers. Cemvita’s technology represents a path forward for a potentially significant supply of SAF and it’s our hope that this offtake agreement for up to one billion gallons is just the beginning of our collaboration.”

Founded in Houston in 2017 by brother-sister team Moji and Tara Karimi, Cemvita's biotechnology can mimic the photosynthesis process, turning carbon dioxide into feedstock. The company's SAF plan hopes to increase reliability of existing SAFs and lower impact of fuel creation.

“Biology is capable of truly amazing things,” Moji Karimi, CEO of Cemvita, says in the release. “Our team of passionate, pioneering, and persistent scientists and engineers are on a mission to create sustainable BioSolutions that redefine possibilities.”

“We are thrilled to partner with United Airlines in working towards transforming the aviation industry and accelerating the energy transition,” he continues. “This agreement featuring our unique SAF platform is a major milestone towards demonstrating our journey to full commercialization.”

Earlier this year, United, which was reportedly the first airline to announce its goal of net zero carbon emissions by 2050, launched its UAV Sustainable Flight FundSM. The fund, which named Cemvita to its inaugural group of portfolio companies, has raised over $200 million, as of this summer.

XSpace adds 3 Houston partners to fuel national expansion

growth mode

Texas-based XSpace Group has brought onboard three partners from the Houston area to ramp up the company’s national expansion.

The new partners of XSpace, which sells high-end multi-use commercial condos, are KDW, Pyek Financial and Welcome Wilson Jr. Houston-based KDW is a design-build real estate developer, Katy-based Pyek offers fractional CFO services and Wilson is president and CEO of Welcome Group, a Houston real estate development firm.

“KDW has been shaping the commercial [real estate] landscape in Texas for years, and Pyek Financial brings deep expertise in scaling businesses and creating long‑term value,” says Byron Smith, founder of XSpace. “Their commitment to XSpace is a powerful endorsement of our model and momentum. With their resources, we’re accelerating our growth and building the foundation for nationwide expansion.”

The expansion effort will target high-growth markets, potentially including Nashville, Tennessee; Orlando, Florida; and Charlotte and Raleigh, North Carolina.

XSpace launched in Austin with a $20 million, 90,000-square-foot project featuring 106 condos. The company later added locations on Old Katy Road in Houston and at The Woodlands Town Center. A third Houston-area location is coming to the Design District.

XSpace condos range in size from 300 to 3,000 square feet. They can accommodate a variety of uses, such as a luxury-car storage space, a satellite office, or a podcasting studio.

“XSpace has tapped into a fundamental shift in how entrepreneurs and professionals want to use space,” Wilson says. “Houston is one of the best places in the country to innovate and build, and XSpace’s model is perfectly aligned with the needs of this fast‑growing, opportunity‑driven market.”

Houston suburb ranks as No. 3 best place to retire in Texas

Rankings & Reports

Texas retirees on the hunt for the right place to settle down and enjoy their blissful retirement years will find their haven in the Houston suburb of Pasadena, which just ranked as the third-best city to retire statewide.

A new study conducted by the research team at RetirementLiving.com, "The Best Cities to Retire in Texas," compared the affordability, safety, livability, and healthcare access for seniors across 31 Texas cities with at least 90,000 residents.

Wichita Falls, about 140 miles northwest of Dallas, claimed the top spot as the No. 1 best place to retire in Texas.

The senior living experts said Pasadena has the best healthcare access for seniors in the entire state, and it ranked as the No. 8 most affordable city on the list.

"Taking care of one’s health can be stressful for seniors," the report said. "Harris County, where [Pasadena is] located, has 281.1 primary care physicians per 1,000 seniors — that’s almost 50-fold the statewide ratio of 5.9 per 1,000."

Pasadena ranked 10th overall for its livability, and ranked 25th for safety, the report added.

Meanwhile, Houston proper ranked as the No. 31 best place to retire in Texas, but its livability score was the 7th best statewide.

Seven of the Lone Star State's top 10 best retirement locales are located in the Dallas-Fort Worth Metroplex: Carrollton (No. 2), Plano (No. 4), Garland (No. 5), Richardson (No. 6), Arlington (No. 7), Grand Prairie (No. 8), and Irving (No. 9). McAllen, a South Texas border town, rounded out the top 10.

RetirementLiving said Carrollton has one of the lowest property and violent crime rates per capita in Texas, and it ranked as the No. 5 safest city on the list. About 17 percent of the city's population is aged 65 or older, which is higher than the statewide average of just 14 percent.

The top 10 best place to retire in Texas in 2026 are:

  • No. 1 – Wichita Falls
  • No. 2 – Carrollton
  • No. 3 – Pasadena
  • No. 4 – Plano
  • No. 5 – Garland
  • No. 6 – Richardson
  • No. 7 – Arlington
  • No. 8 – Grand Prairie
  • No. 9 – Irving
  • No. 10 – McAllen
