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. Read the full story here.

Many of the estimated 50 million Americans who suffer from chronic pain turn to drugs — including heavily abused opioids — to relieve their symptoms. Houston-based startup Portable Therapeutix LLC's drug-free solution to pain management seeks to put a dent in the market for prescription painkillers.

In 2018, Houston-based Portable Therapeutix introduced Squid Go, a portable device that's designed to ease the pain and swelling of sore joints and muscles. It's a follow-up to the company's Squid Compression, a pain management device launched in 2013 for patients at rehabilitation centers, hospitals, doctor's offices, and the like.

Several years ago, David Grimes had a business partner who played dirty. It wasn't until the trial that followed the business wrongdoing that Grimes discovered the man had a history of cheating companies out of money. Grimes envisioned a software service that used public information to research potential investors or associates before signing on the dotted line of a partnership.

"I wanted to find a tool that would alleviate that pain and that risk of doing business," Grimes says. "I couldn't find that tool." Read the full story here.

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." Read the full story here.

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.

Tesla forced to recall nearly all Cybertrucks in latest setback

Tesla Talk

U.S. safety regulators on Thursday recalled virtually all Cybertrucks on the road, the eighth recall of the Tesla-made vehicles since deliveries to customers began just over a year ago.

The National Highway Traffic Safety Administration's recall, which covers more than 46,000 Cybertrucks, warned that an exterior panel that runs along the left and right side of the windshield can detach while driving, creating a dangerous road hazard for other drivers, increasing the risk of a crash.

The stainless steel strip, called a cant rail assembly, between the windshield and the roof on both sides, is bound to the truck’s assembly with a structural adhesive, the NHTSA report said. The remedy uses an adhesive that’s not been found to be vulnerable to “environmental embrittlement,” the NHTSA said, and includes additional reinforcements.

Tesla will replace the panel free of charge. Owner notification letters are expected to be mailed May 19, 2025.

The recall of 46,096 Cybertrucks covers all 2024 and 2025 model years, manufactured from November 13, 2023, to February 27, 2025. The NHTSA order says that Tesla became aware of the problem early this year.

Videos posted on social media showing people ripping the panels off of Cybertrucks with their hands have gone viral in recent days.

The Cybertruck, which Tesla began delivering to buyers in late 2023, has been recalled eight times in the past 15 months for safety problems, including once in November because a fault in an electric inverter can cause the drive wheels to lose power. Last April, the futuristic-looking trucks were recalled to fix acceleration pedals that can get stuck in the interior trim. Other recalls were related to windshield wipers and the display screen.

It's the latest setback for the Elon Musk-owned electric automaker, which has come under attack since President Donald Trump took office and empowered Musk to oversee a new Department of Government Efficiency that’s slashing government spending.

While no injuries have been reported, Tesla showrooms, vehicle lots, charging stations and privately owned cars have been targeted.

Prosecutors in Colorado charged a woman last month in connection with attacks on Tesla dealerships, including Molotov cocktails thrown at vehicles and the words “Nazi cars” spray-painted on a building.

And federal agents in South Carolina last week arrested a man they say set fire to Tesla charging stations near Charleston. An agent from the Bureau of Alcohol, Tobacco, Firearms and Explosives wrote in an affidavit that authorities found writings critical of the government and DOGE in his bedroom and wallet.

Even before the attacks ramped up in recent weeks, Tesla has been struggling, facing increased competition from rival electric vehicles, particularly out of China.

Though largely unaffected by Thursday's recall announcement, Tesla shares have plummeted 42% in 2025, reflecting newfound pessimism as sales crater around the globe.

With regard to Thursday's recall, Cybertruck owners may contact Tesla customer service at 1-877-798-3752 and the National Highway Traffic Safety Administration Vehicle Safety Hotline at 888-327-4236, or go to nhtsa.gov.

$100,000 salary goes further in Houston than most cities, study shows

Cashing In

Even with Houston's ever-changing cost of living, earning a six-figure salary in the city is going much further than it used to, according to an income study by fintech company SmartAsset.

An annual $100,000 salary in Houston is worth $83,343 after taxes and when adjusted for the city's cost of living, the report revealed. That's $5,254 more than what six-figure-earning Houstonians were bringing home last year, a separate report from GoBankingRates.com found.

In SmartAsset's rankings of U.S. cities where $100,000 is worth the most, Houston ranked ninth.

The report warns a six-figure salary may seem comfortable at first, but it may not stretch as far depending on where an individual lives, any applicable tax obligations, and the rate of inflation.

"Earning $100,000 places an individual tax filer at the upper limit of the 22 percent federal tax bracket," the report's author wrote. "But taxes aren’t the only factor. The cost of living varies widely across the country, affecting how much purchasing power remains after necessary expenses."

Manhattan, New York is the No. 1 place where a six-figure salary is worth the least, where a New Yorker's take-home pay is only worth $30,362 after taxes and adjusted for the cost of living.

Other U.S. cities where a $100,000 salary goes the furthest
The U.S. city where a six-figure salary goes the furthest is Oklahoma City, where residents come away with $89,989 after all expenses.

Texas cities dominated the top 10 list. Texas doesn't impose state or local income taxes, which likely boosted its statewide six-figure salary value.

Six-figure earners living in El Paso see the greatest amount in take-home pay statewide, according to SmartAsset, with residents making $89,114 annually after taxes and expenses in 2025. That's $274 more than 2024's take-home pay.

The three additional Texas cities where a $100,000 salary goes the furthest after taxes and expenses are:

  • No. 3 – Corpus Christi ($88,015)
  • No. 6 – Lubbock ($86,846)
  • No. 7 – San Antonio ($86,084)

Six-figure salaries don't stretch as far in Dallas-Fort Worth. An annual $100,000 salary in Dallas is worth only $77,197 after taxes and expenses, which is about $900 less than what six-figure-earning Dallasites brought home in 2024.

Those living in Plano are taking home even less: The study says a Plano resident's six-figure salary is only worth $71,372 in 2025.

In the report's rankings of U.S. cities where $100,000 is worth the least, Plano ranked at No. 26, while Dallas ranked 38th.

SmartAsset used its paycheck calculator to apply federal, state and local taxes to an annual salary of $100,000 in 69 of the largest American cities, which was then adjusted for the local cost of living (which included average costs for housing, groceries, utilities, transportation, and miscellaneous goods and services).
