Houston-based ComboCurve is growing rapidly. The energy software company has raised over $60 million in venture capital investment — $50 million of which was closed in the company’s series B round earlier this year. Since the original product launched in May of 2020, CEO and Co-Founder Armand Paradis says the platform has almost 200 companies on it.

“We built something that resonated with the market — and we were super passionate about the product and taking care of our industry,” Paradis says on the Houston Innovators Podcast. “We don’t want to be the best in oil and gas. We want to be the best software company." Click here to read more.

Houston-based medical device company Ictero Medical closed its oversubscribed series A at $6 million. The funding round was led by MedTex Ventures, S3 Ventures, and an undisclosed strategic investor. The company's novel cryoablation system was designed to treat high-risk gallstone disease patients and provide a less invasive and lower risk alternative to gallbladder removal surgery — something over 1 million Americans undergo annually.

“Our technology provides an immediate solution for critically ill patients who currently have no good treatment options, and also has the potential to benefit healthier patients who want to avoid surgery,” says Ictero Co-Founder and CEO Matthew Nojoomi in the release. Click here to read more.

Fresh off a $50M series B, fast-growing Houston startup aims to upgrade energy sector tech

Houston innovators podcast episode 132

The energy industry has historically made critical and timely decisions with antiquated and disjointed software, and that just was not ideal for Armand Paradis.

“In our space, all the decisions are expensive,” Paradis tells the Houston Innovators Podcast. “We could go all the way into the billions of dollars making decisions using software from 30 or 40 years ago. I really thought this was a problem.”

Paradis, observing this opportunity in the industry, left his job at Equinor to launch ComboCurve, a comprehensive and more effective software platform for various verticals within the energy industry.

ComboCurve has raised over $60 million in venture capital investment — $50 million of which was closed in the company’s series B round earlier this year. It wasn’t just funding ComboCurve expanded over the past few years. The original product launched in May of 2020 and in 2021, added around 100 companies onto its platform. Now, not even halfway through 2022, almost 200 companies use the software.

“We built something that resonated with the market — and we were super passionate about the product and taking care of our industry,” Paradis says on the podcast.

“We don’t want to be the best in oil and gas. We want to be the best software company,” he continues.

One focus ComboCurve has is on the energy transition. He says energy companies are making moves in lowering their carbon emissions and investing in greener technology — they just might not be talking about it.

“We want to be the role model — the company that’s being super proactive in their environmental practices,” Paradis says. “To be able to do that, you have to be open and proactive about reducing emissions. The other piece is to talk about it.”

At this point, Paradis says we need all energy — fossil fuels, nuclear, renewables, etc. This year, ComboCurve will roll out its GHG, or greenhouse gas, module to help customers track and lower their emissions.

“We are working with a handful of operators working in this space,” he says. “We want to allow for operators to be able to predict their emissions and see the impact on their projects.”

Houston-based ComboCurve announced today that it has raised $50 million through a series B funding round led by Dragoneer Investment Group and Bessemer Venture Partners.

Founded in 2017, the company is a cloud-based energy analytics and operating platform that uses sophisticated software to forecast and report on a company's energy assets, including renewables.

The series B capital will allow the company to enhance its core product, while also adding on other workflows that focus on emissions and renewable energy.

ComboCurve raised its series A less than six months ago, according to a release. The company was founded by Armand Paradis and Jeremy Gottlieb, who have backgrounds in engineering and finance, respectively.

“ComboCurve was created to solve critical pain points, helping energy companies better manage their forecasting, valuation, reporting and decision-making functions,” Paradis, who also serves as CEO, said in a statement. “Our solution has resulted in widespread adoption by many of the world’s leading energy companies, and this investment led by Dragoneer and Bessemer, two of the world’s leading technology investment firms, will enable us to engage with additional energy companies to operate more efficiently.”

Since the completion of the company's series A, ComboCurve has taken on more than 170 customers, including the likes of Devon Energy and Pioneer Natural Resources, according to ComboCurve's website.

The company describes its platform as a "supercharged Aries but easy to use," referring to the ARIES Petroleum Economic Software by Landmark Solutions, on LinkedIn. The platform provides forecast modules, workflows and fully integrated economics, with GHC and carbon reporting features in the works that will allow users to estimate future emissions.

“ComboCurve is in the early innings of building a truly enduring franchise that is rapidly becoming the software backbone of their customers’ day-to-day operations,” Christian Jensen, partner at Dragoneer Investment Group, said in a statement. “We are excited to partner with Armand and his world-class team as they continue to deepen their suite with existing customers and expand their platform into renewables, emissions reporting, and all corners of the energy market.”

Elon Musk's SpaceX is about to make its debut on Wall Street

Money Moves

Elon Musk's rocket company SpaceX will make its debut on Wall Street Friday, June 12, and both institutional and retail investors are expected to gobble up the 555.6 million shares going up for sale at $135 apiece. Musk, already the world's richest man, could become its first trillionaire.

SpaceX is likely to become the biggest IPO ever, with proceeds of around $75 billion. SpaceX hopes to become the first company to send people to Mars. In fact, part of Musk’s future compensation depends on SpaceX eventually establishing a colony of at least 1 million people on the red planet.

Why SpaceX is going public now

In a video conference on Musk's social media platform X, he told JPMorgan CEO Jamie Dimon that people have suggested for the last 10 years that he take SpaceX public. He's doing it now because the company plans to put 100,000 next-generation Starlink satellites into orbit. Deploying AI data centers in space is a “massive new growth base and you need capital for that,” he said.

Going public provides access to the capital that SpaceX needs. But it also exposes it to more scrutiny from shareholders and more regulatory oversight. That includes filing quarterly financial reports, which critics say incentivizes short-term thinking over longer-term planning and creates unnecessary costs for a company. Securities regulators are currently soliciting public comment on a proposal to require public companies to file the financial reports only twice every year.

How the IPO impacts the company

Musk will hold the majority of a special class of shares, giving him control over decisions related to company strategy, finances and personnel. On the latter, because of his ownership of most of these Class B shares, the only person who can fire Musk as CEO is Musk.

The company credits Musk with being the “driving force” behind its growth, innovation and success. But what happens if Musk is no longer in the picture? SpaceX warns that the loss of Musk could disrupt its ability to execute its strategy as well as hurt its “reputation and relationships with customers, partners and other stakeholders.”

The company also warns that finding a replacement with the same skills and experience as Musk would be time-consuming, if not nearly impossible. As Wedbush Securities analyst Dan Ives wrote Wednesday, “At the end of the day Musk is SpaceX and SpaceX is Musk.”

What could make or break SpaceX

Currently in the test phase, the gigantic reusable Starship rocket is key to SpaceX realizing Musk's ambitions. Much of the commercial space business hinges on SpaceX developing Starship’s capability to be fully reusable and hearty enough for a quick turnaround between flights. If that doesn't happen, SpaceX warns that putting data centers and satellites in space will take longer and cost more money, meaning it risks customers bailing on the company.

Analysts say that by pioneering reusable rockets, SpaceX has established a clear lead on competitors such as Blue Origin, led by Amazon founder Jeff Bezos. The Starlink satellite business competes with, among others, AST SpaceMobile – which is relying on a SpaceX rocket to send its latest generation of satellites into orbit next week.

The prospectus filed last week says SpaceX’s biggest potential market is the sale of business-oriented artificial intelligence products designed to transform how people get work done. It’s an opportunity SpaceX predicts would be worth $22.7 trillion if it could somehow dominate rivals like Anthropic, OpenAI and Microsoft in a highly competitive industry. But the prospectus shows no clear path to profitability for the xAI business, which merged with SpaceX earlier this year.

Why Wall Street is paying attention

If the SpaceX IPO is as successful, the stock could quickly join the Nasdaq 100, a widely followed index that tracks the 100 largest non-financial companies in the composite. That's important because some popular funds, such as the $460 billion QQQ exchange-traded fund, mimic the index and will automatically buy whatever is listed in the index.

Nasdaq recently changed its rules to allow select companies to enter the Nasdaq 100 after just 15 trading days.

S&P Dow Jones Indices, on the other hand, is sticking to established and more traditional thresholds that will not allow SpaceX or other companies with gargantuan IPOs faster entry into its S&P 500 index. That means even high-profile companies will still need to wait for their stocks to trade a full 12 months before they can enter the index.

Companies want to be in the S&P 500 in particular because it's arguably the most important index on Wall Street, with trillions of dollars either mimicking it exactly or benchmarked against it. Vanguard's VOO fund that tracks the S&P 500 has roughly $950 billion invested in it, for example.

NASA unveils Artemis III astronauts at Johnson Space Center in Houston

To the moon

NASA on Tuesday, June 9, revealed the crew for its Artemis III mission, the next step in the space agency's plan to eventually land astronauts on the moon.

The announcement came two months after Artemis II's record-breaking trip around the moon that surpassed the distance record of Apollo 13.

NASA's Randy Bresnik, Frank Rubio, Andre Douglas and the European Space Agency's Luca Parmitano won't fly to the moon or land on the surface. Instead, they’ll orbit Earth while practicing docking their Orion capsule with two lunar landers.

“To the Artemis III crew, we wish you Godspeed on the journey ahead,” said NASA administrator Jared Isaacman.

Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are racing to deliver the lunar landers. The two-week demo is targeted for 2027. Blue Origin suffered a recent setback when its massive rocket exploded during an engine-firing test on the launch pad in Florida, shaking nearby homes and illuminating the sky with an orange fireball.

NASA's Jeremy Parsons said the setback is a learning opportunity and that the space agency is confident Blue Origin's rocket will be ready in time.

NASA's Artemis program aims to return astronauts to the moon's surface for the first time since the 1970s. A recent revamp of the program announced by Isaacman aims to fast-track it similarly to the Apollo era, adding the upcoming spaceflight around Earth before eyeing a lunar landing in 2028.

“We are certainly humbled as a crew to be able to be your crew that executes this Artemis III mission in space,” said Bresnik, Artemis III commander.

Added Douglas, mission specialist: “My brain — it is going a mile a minute right now. But my heart, it is so warm. It is so full."

In May, NASA awarded hundreds of millions of dollars in contracts to four companies, including Blue Origin, to build landers, rovers and drones for a future moon base. Isaacman said the goal of the moon base is to lay the foundation for a Mars expedition.
