From restaurant review apps to a device that monitors oil rigs, this week's innovators to know are tech savvy to say the least. All three took a chance on Houston for their startups, and that chance is paying off.

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.

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.

9 Houston-based companies make Fortune Global 500 list in 2026

Worldwide Rankings

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.

Fast-growing Houston real estate startup surges to No. 7 on Inc. 5000

growth report

Houston-based Epique Realty has ridden the AI wave to rank among the Inc. 5000’s 10 fastest-growing private companies.

With three-year revenue growth of 23,210 percent, the AI-powered real estate brokerage appears at No. 7 on this year’s Inc. 5000 list. The 2026 list ranks private companies based on percentage revenue growth from 2022 to 2025.

Epique, founded in 2021, also ranks as the No. 1 fastest-growing company in Houston, No. 1 fastest-growing real estate company in the U.S., and No. 2 fastest-growing company in Texas.

Epique’s annual revenue surpasses $91 million

Between 2022 and 2025, the company’s annual revenue skyrocketed from $391,654 to more than $91.2 million. In 2025, the brokerage closed more than 23,000 deals and surpassed $7 billion in total sales, elevating Epique to the country’s 14th-largest real estate brokerage as measured by volume.

Epique’s network has more than 4,000 agents.

“To debut in the top 10 of the Inc. 5000 is absolute proof that when you relentlessly put agents first, exponential growth takes care of itself,” co-founder and CEO Joshua Miller said in a news release.

“We didn’t achieve this by following the industry playbook; we achieved this by burning it,” Miller added. “By fully funding our agents’ success through free health care, proprietary AI, and world-class leads, we’ve built a company where agents can finally thrive.”

The company’s other co-founders are Chris Miller, chief operating officer and vice president of expansion, and Janice Delci, chief financial officer.

Epique expands business to Canada, Mexico, Australia

The Millers and Delci have guided the company’s rapid expansion.

“Scaling our corporate support team to match [our] hyper-growth while seamlessly expanding across all 50 states and internationally to Canada, Australia, and Mexico takes an incomparable operational infrastructure,” Miller said.

“We have built an enterprise-grade technology ecosystem that allows us to absorb overhead and empower our agents at lightning speed,” he added. “This ranking validates that our disruptive model is working, and it is completely redefining the global industry standard.”

Epique launched its platform in 2023, touting itself as the industry’s first AI-powered brokerage. The startup’s platform provides AI tools for real estate agents to improve their marketing, streamline content creation, and boost engagement with clients and prospects.

Among Epique’s AI tools are:

  • ChatGPT for generation of property descriptions
  • AI-assisted creation of blog posts and agents’ bios
  • Production of Instagram quotes for social media marketing

“When we started Epique, we wanted to build a company that genuinely cared for its agents’ financial and physical well-being,” Delci says. “To see that vision translate into this level of historic record-breaking growth is a beautiful testament to the true power of radical generosity.”

Epique and fellow honorees will be recognized Oct. 14-16 at the 2026 Inc. 5000 Conference & Gala in Dallas.
