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.

KBR names C-suite duo to lead $5.3B government services spinoff

new leaders

In advance of the spinoff of its Mission Technology Solutions unit, Houston-based KBR has made two C-suite hires for the new business.

Michael LaRouche is coming aboard as president and CEO of the spinoff, currently called SpinCo, on Sept. 26. Nicholas Veasey is joining as executive vice president and chief financial officer on July 1.

“Michael and Nick bring a highly complementary combination of operational leadership, financial expertise, and mission-driven experience, and together they will accelerate our impact for stakeholders,” Stuart Bradie, chairman, president and CEO of publicly traded KBR, said in a news release.

LaRouche currently is CEO of Serco North America, a Herndon, Virginia-based government services contractor. Veasey most recently was CFO of MAG Aerospace, a Fairfax, Virginia-based defense contractor.

SpinCo, a government services contractor, will launch with more than $5.3 billion in annual revenue and 20,000 employees. KBR’s total headcount is around 36,000. Branding for SpinCo, including a formal name, will be revealed in July.

“SpinCo is positioned as a top-tier provider of differentiated technology solutions, anchored by deep mission expertise, global scale, and a relentless commitment to delivering for our customers,” LaRouche says.

After the spinoff, the slimmed-down KBR will focus on its Sustainable Technology Solutions business, a provider of energy and industrial technology that generated $2.5 billion in revenue in 2025. Bradie will remain chairman, president and CEO of the business.

Both SpinCo and the new KBR will be public companies. The spinoff is scheduled to be completed in January.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
