Christopher Robart — along with his twin brother, Alex — is in the business of business development. The two run Ambyint, an oil and gas tech company that creates the Nest thermostat of oil rigs.

The company is looking to expand its customer base this year, as well as grow to be able to service different types of rig pumps.

What started as a quest to find the best Moscow Mule in Southern California has turned into growing business thriving in Houston's dining scene. Sumit Sikka first visited Houston for an event to promote the app he co-founded, Crityk, and basically never left.

"I packed up some of my bags and decided to try here in Houston," Sikka says." It's a lot easier to get to decision makers here in Houston than in LA."

Moji Karimi never thought his oil and gas career would overlap with his sister's medical research. But in some ways, the fact the two of them teamed up to create a company that takes carbon dioxide from the air and turns it into something else, makes perfect sense that it crosses industries.

"There are a lot of opportunities bringing a proven science or technology from one industry into another to solve problems," he says.

One night, Sumit Sikka was on a quest to find the best Moscow Mule in Santa Monica. He couldn't find anything helpful online, and when he finally did get a good recommendation, he was already done for the night.

It was through this experience that Sikka knew he wanted to make a restaurant finder app, but he wanted to do something different from Yelp or Google Reviews. On those platforms, a restaurant can get crushed by a bad review that provides false information. So, when he started getting the ball rolling on Crityk, he realized he needed to give the restaurants a voice.

"That was kind of the first big pivot," Sikka says. "First, we had an app based on user content. Then we pivoted to have content curated by the restaurant. For the first time ever, the restaurant gets to create their own profile."

The app launched on November 18 and has over 700 restaurant profiles live. There are 250 here in Houston, and 25 are clients, meaning they pay Crityk and have exclusive marketing opportunities, like promoting events — something most restaurants struggle to engage customers with.

"Restaurants do so much marketing, but they do the majority of it inside the restaurant," Sikka says. "Who's not going into your restaurant and not seeing that?"

Crityk users can log into the app and find different restaurant events around town to attend. Users can upload images of food from different restaurants. They rate the specific menu item, rather than the restaurant as a whole. Then, restaurants can link that photo to the specific menu item. Instead of comments on the picture, users can engage with hashtags. Any comments a user might have would go directly to the establishment to be resolved.

Another priority for Crityk is to have photos of every menu item the restaurant offers as well as complete dietary information. It's becoming more and more important for diners to know about vegan, gluten-free, etc. options before getting to the restaurant only to be disappointed with the selection.

Investing in Houston
While the idea came about in California, Sikka, who has a sister who lives in The Woodlands, took a trip to Houston to feel out consumer interest in the app. He hosted an event with a local restaurant and some influencers. The app kind of just exploded in town, Sikka says.

"I packed up some of my bags and decided to try here in Houston," Sikka says." It's a lot easier to get to decision makers here in Houston than in LA."

The development team is still based in India, and Crityk's co-founder, John Kegel, is still based in California. However, Sikka works out of Station Houston, something he says has been an extremely valuable. He says he's made some valuable connections through both Station and the Texas Restaurant Association.

"I think Houston is a phenomenal city to get started in. It's a big city, but it has the feeling of a small city."

Second course?
Still under two months old, the app has a lot of improvements and expansions in the works. Sikka says he wants to double the number of restaurant profiles to 500 by summer. He'd also like to grow the number of paying clients on the site, which would include more restaurants with a full photo menu on the app for users to browse.

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
