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.

Oil and gas startup exec positions Houston company for more growth in 2019

Featured Innovator

Most of Christopher Robart's 10-year career in oil and gas has been deliberate and calculated — researching the right startup to be involved in or finding the right buyer for a company he invested in. However, his actual start in the industry wasn't so intentional.

"I sort of fell into oil and gas after I got of college back in 2003," says Robart, who is the president of Ambyint USA. "Before that, I was involved in a few startup things — some digital and some not. I was always sort of an entrepreneur."

Robart shares the passion of entrepreneurialism with his twin brother, Alex, CEO of Ambyint. The two have similar work experiences, since they act as an oil and gas startup team in Houston. One of the first companies the duo bought and sold was PacWest Consulting Partners, which was sold to IHS Energy in 2014, Robart says. The second one, Digital H2O, they founded, grew the team, lead some investments, and sold it to Genscape in 2015.

The pair's newest endeavor is Ambyint, an oilfield smart technology company with Canadian origins. The Robart brothers have been involved in it for about two and a half years.

Christopher Robart spoke with InnovationMap about his career and what he hopes to accomplish with his oil and gas startup in 2019.

InnovationMap: How did you and your brother first get involved in Ambyint?

Christopher Robart: After we left IHS, we knew that our next up was going to be software and upstream oil and gas, but there were a lot of question marks. We did our due diligence. We leveraged all that information we found and settled on which market we wanted to be in. We ended up finding Ambyint and liked what they had built to date, but they had some gaps and shortcomings, particularly on the commercial side, and they had no U.S. presence. We thought those two gaps were something we'd be helpful filling out. We went through a fairly lengthy process to lead an investment into the company, and essentially took over through that process.

IM: So, Ambyint still has an office in Canada?

CR: The Canada office is primarily a technology office, with some sales capabilities up there. The U.S. is primarily sales, marketing, and customer support.

IM: How does the technology work?

CR: The easiest way to explain it is we're like a Nest thermostat for your oil wells. It's a piece of hardware and a piece of software. It's wired into the well's control system and tied up to cloud-based software. From there, we've been deploying artificial intelligence, machine learning, deep learning, etc.

IM: What do you look for in customers?

CR: Oil companies of any shape or size, really. Oil and gas industry aren't really known for being early adopters of technology. There's a lot of resistance to change, particularly at the production level, which we focus on. So we're looking for early adopters looking to lead the way.

We're in pretty much all the major oil-producing areas in the U.S. and Canada. We also have customers in Mexico, Chili, and Egypt. There's a few more countries in the Middle East we're trying to get into.

IM: Are you planning another fundraising round?

CR: We'll embark on a series B in the near future. We closed our series A, and it was pretty large, so we're in a good place. (The series closed in September of 2017 with $11.5 million raised, according to Crunchbase.)

IM: What are your goals for 2019?

CR: We've built a lot of cool technology, and we continue to do that. Our focus for 2019 is to continue to commercialize and expand our customer base. Our sales cycle is pretty long. It could be a year from the time we bring an initial lead to the table, running a pilot, getting results, and developing a plan. It's a long, slow, and, in some cases, a painful process.

When you're doing things like machine learning, you're teaching a machine how to do something a human would do something. What's required to do that is a massive amount of data to start, and from there, it's a never ending journey of data collection and monitoring your accuracy.

We've been focused on one specific artificial lift pump — every well will eventually take a piece of artificial lift pump. We work on the most common artificial lift pump, but it's just one of six key types. In addition to selling more of that pump, we are in the process of expanding to additional lift types.

IM: What keeps you up at night, as it pertains to your business?

CR: Change management. Getting our customers to adopt new technology and embrace change. That's it. We're constantly trying to get our customers to move more quickly.

IM: How do you and your brother work together? Do you each play different roles in the company?

CR: Our backgrounds are similar. We're twins, but we have personality differences. I spend a little more time with our customers than he does and with new product initiatives. I get pretty hands on.

His mandate is less focused on walking and talking with customers and more on managing the functions of the business and working with the leadership team. As well as financing and fundraising.

We've got a pretty good division of labor, but there is a lot of overlap of what we do.

IM: What are some of the pros and cons of being in Houston?

CR: Obviously the pro of being in Houston is it being the oil capital of the world. All our customers are here. It's sort of a must.

The downside of running a technology company in town is that tech talent is quite thin on the ground in Houston — especially what we're looking for. So, we don't have any tech team members in the Houston office. I'll put it mildly in that we are skeptical of the talent pool for really strong software developers in the Houston market.

Houston ranks No. 2 for share of AI talent in professional services

AI surge

Houston’s professional and business services sector—think law, accounting, consulting, and engineering firms—grabs one of the industry’s biggest shares of AI talent.

A report from commercial real estate services giant CBRE ranks Houston No. 2 among the top 50 U.S. and Canadian tech markets for the concentration of AI talent in professional and business services.

Houston’s share of AI talent in professional and business services stands at 26 percent, the report shows. Washington, D.C., tops the list at 31 percent. At 25 percent, Dallas-Fort Worth claims the No. 3 spot.

CBRE based the AI ranking on data from the LinkedIn networking platform.

The company’s researchers tallied 11,709 AI-related tech jobs in Houston. Nationwide, data scientists lead AI-related job growth in the U.S., according to the report.

“AI software and hardware developers are currently the most sought-after tech talent by employers,” the report says.

Houston faces AI talent gap

DoubleTrack, a provider of AI and data consulting, reported in June that Houston faces an AI talent gap.

“The places where businesses say they will adopt AI over the next six months, well ahead of where they are today, are mostly the same places already short on talent: Miami, Houston, and Denver among the metros, South Dakota and South Carolina among the states,” DoubleTrack said.

This labor shortage comes amid Houston’s ascent as an AI hub. For instance, a factory being built here by AI chipmaker NVIDIA and electronics manufacturer Foxconn will produce AI supercomputers and infrastructure systems.

Houston’s place in the sphere of tech talent

Overall, Houston ranks No. 32 in the CBRE report among the top 50 U.S. and Canadian markets for tech talent. The San Francisco Bay Area claims the top spot, with Austin at No. 5 and DFW at No. 8.

CBRE relied on 13 metrics to rank tech talent markets, including concentration of tech talent, tech talent pipeline, and research-and-development investments.

Here are other Houston details from the report:

  • In 2025, Houston’s tech talent workforce numbered 104,080, up 7.3 percent over the past three years.
  • Houston’s average wage for tech talent within the tech industry was $120,216 in 2025, up 13.3 percent over the past three years.

New pilot program for air taxis, Project Nexus, takes flight in Texas

Project Nexus

By 2029, Texas skies could be buzzing with air taxis, much like they are with drones today.

To kick off the "Project Nexus" pilot program in Texas, U.S. Transportation Secretary Sean Duffy, U.S. Sen. Ted Cruz, and Texas Department of Transportation officials attended an event September 10 at Fort Worth Alliance Airport, which serves as the launchpad for a statewide pilot program that could result in air taxis, self-piloted planes, and vertical take-off-and-landing aircraft permanently buzzing across the skies of Texas.

It was the first demonstration in Texas of next-generation aircraft under the pilot program; Texas is the sixth state to participate in the program.

Air taxi service on the radar
The federal government has teamed up with aviation companies BETA Technologies and Joby Aviation, as well as the Texas Department of Transportation, to develop regional air taxi service in Dallas, Austin, San Antonio, and eventually Houston.

Roger Venables, Fort Worth’s aviation director, said in January that he foresees regular air taxi service becoming a reality in the next five years.

On September 12, a Joby-made electric air taxi took a roundtrip flight between Fort Worth Alliance and Dallas Fort Worth International Airport to test flight operations.

The mission was part of a five-day test involving Fort Worth Alliance and DFW Airport flights, and flights over the Fort Worth Stockyards, Toyota Motor North America’s Plano headquarters, and other sites.

A new facility at Fort Worth Alliance will be Joby’s long-term home for regional flight operations.

Building a 'framework' for electric aircraft
TxDOT said Project Nexus is aimed at creating “a scalable system” to connect urban areas, rural communities, and neighboring states as air mobility technology advances.

In a TxDOT release, Marc Williams, the agency’s executive director, said the pilot program will “build a framework for how electric aircraft could one day connect people, goods, and communities across the state.”

Three-phase project will test flight capabilities

Initial flights in the third-year pilot program won’t carry passengers, according to TxDOT. Instead, the flights will gather data, validate air travel routes, and help improve the safety of air mobility technology.

The first phase of the U.S. Department of Transportation’s Project Nexus will feature piloted aircraft such as helicopters and fixed-wing planes. CultureMap previously reported Plano-based VertiPorts by Atlantic, which develops takeoff and landing sites for airplane-helicopter hybrids, would be part of Project Nexus.

The second phase will involve testing airborne medical and cargo logistics. This includes transporting critical medical supplies or donor organs between rural and urban hospitals in the Austin and San Antonio areas.

In the third and final phase, passengers will fly aboard air taxis across the Texas Triangle. Dallas-Fort Worth, Austin, Houston, and San Antonio anchor the triangle.

“In Texas, we don’t wait for the future to arrive, we build it,” Cruz said in the TxDOT release. “The Lone Star State is pushing the boundaries by testing the next generation of aircraft through Project Nexus.”

“These technologies will connect communities, expand access to jobs and services, and strengthen supply chains,” the senator added. “What starts in Texas will help shape the future of aviation throughout the entire country.”

Houston-area NASA contractor plans Nasdaq IPO

going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.
