3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from health tech to energy software — recently making headlines in Houston innovation.

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.

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.”

money moves

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.”
