Wondering what energy tech companies you should keep an eye on? Wonder no more.

As a part of 2021 CERAWeek by IHS Markit, the Rice Alliance for Technology and Entrepreneurship hosted a virtual pitch competition today featuring 20 companies in four sessions. Each entrepreneur had four minutes to pitch, and then a few more to take questions from industry experts.

"Of the companies here today, we've intentionally selected a diverse group," says Brad Burke, managing director of the Rice Alliance at the start of the event. "They range from companies looking for their seed funding to companies that have raised $20 million or more."

The following companies pitched at the event: Acoustic Wells, ALLY ENERGY, Bluefield Technologies, Cemvita Factory, Connectus Global, Damorphe, Ovopod Ltd., DrillDocs, GreenFire Energy, inerG, Locus Bio-Energy Solutions, Nesh, Pythias Analytics, REVOLUTION Turbine Technologies, Revterra, ROCSOLE, Senslytics, Subsea Micropiles, Syzygy Plasmonics, Transitional Energy, and Universal Subsea.

At the end of each session, attendees voted via Zoom poll on which startup had the most potential. According to the event attendees, the most promising energy tech companies are:

REVOLUTION Turbine Technologies

Asheville, North Carolina-based REVOLUTION Turbine Technologies, an inaugural Greentown Houston member company, is working to "put a green spin on power." The company's micro-Expansion Turbine System produces green power for digital oilfield and pipeline initiatives through the recovery of excess natural gas pressure.

"RTT's technology provides a scalable, clean energy source to reliably power digital oilfield and pipeline initiatives at a significantly low operating cost," says Christopher Bean, founder and CEO, in his presentation. "Never has it been more important to make production and pipeline operations greener, safer, and efficient."

Connectus Global

Connectus Global, based in Calgary, provides custom technology solutions that can increase productivity, profits, and competitiveness. Connectus' Real-Time Location System, or RTLS, uses Ultra-Wide Band for communication and triangulation while hosting a Radio Frequency Identification Device, which come in the form of badges, tags, and receivers.

"In our first year, we received $800,000 in revenue and are on track to hit our numbers — $3.6 million — at the end of this fiscal year," says Mike Anderson, CEO of the company, in his presentation." We have a global white labeling agreement with Honeywell and we make up about 75 percent of their digitized workforce management portfolio."

The company's U.S. office is located in Houston.

DrillDocs

Houston-based DrillDocs has created an automated drilling cuttings characterization service, called CleanSight, that supports an operator's understanding of their wellbore's state of stability and cleanness in real time.

"We're taking computer vision to the drilling rig," says Calvin Holt, CEO and co-founder at DrillDocs, in his presentation. "Now for the first time, drilling and geomechanics teams will have unique, real-time data to ascertain the well's condition."

Revterra

Revterra, a Houston-based company and inaugural Greentown Houston member company, is creating a flywheel energy storage system for long-duration grid-scale applications.

"For those of us in Texas, the power outages we experienced a couple weeks ago are a stark reminder that the stability and the resiliency of our electric grid should be a top priority as we transition to low-emission power sources," says Ben Jawdat, founder and CEO at Revterra, in his presentation. "Energy storage is a critical element in both grid stability and enabling our transition to sustainable energy."

5 can't-miss innovation events at CERAWeek featuring Houston speakers

where to be online

While usually hundreds of energy experts, C-level executives, diplomats, members of royal families, and more descend upon Houston for the the annual CERAWeek by IHS Markit conference, this year will be a little different. Canceled last year due to COVID-19, CERAWeek is returning — completely virtually.

The Agora track is back and focused on innovation within the energy sector. The Agora track's events — thought-provoking panels, intimate pods, and corporate-hosted "houses" — can be accessed through a virtual atrium.

Undoubtedly, many of the panels will have Houston representatives considering Houston's dominance in the industry, but here are five innovation-focused events you can't miss during CERAWeek that feature Houstonians.

Monday — New Horizons for Energy & Climate Research

The COVID-19 pandemic has made vivid and real the risks of an uncontrolled virus. Risks posed by climate change are also becoming more palpable every day. At the forefront of understanding these risks, universities are developing solutions by connecting science, engineering, business, and public policy disciplines. Along with industry and governments, universities are critical to developing affordable and sustainable solutions to meet the world's energy needs and achieve net-zero emission goals. Can the dual challenge of more energy and lower emissions be met? What is some of the most promising energy and climate research at universities? Beyond research, what are the roles and responsibilities of universities in the energy transition?

Featuring: Kenneth B. Medlock, III, James A. Baker, III, and Susan G. Baker Fellow In Energy And Resource Economics, Baker Institute and Senior Director, Center For Energy Studies at Rice University

Catch the panel at 1 pm on Monday, March 1. Learn more.

Tuesday — Conversations in Cleantech: Powering the energy transition

With renewables investment outperforming oil and gas investment for the first time ever in the middle of a pandemic, 2020 was a tipping point in the Energy Transition. Low oil prices intensified energy majors' attention on diversification and expansion into mature and emerging clean technologies such as battery storage, low-carbon hydrogen, and carbon removal technologies. Yet, the magnitude of the Energy Transition challenge requires an acceleration of strategic decisions on the technologies needed to make it happen, policy frameworks to promote public-private partnerships, and innovative investment schemes.

Three Cleantech leaders share their challenges, successes, and lessons learned at the forefront of the Energy Transition. What is their vision and strategy to accelerate lowering emissions and confronting climate change? Can companies develop clear strategies for cleantech investments that balance sustainability goals and corporate returns? What is the value of increasing leadership diversity for energy corporations? Can the Energy Transition be truly transformational without an inclusive workforce and a diverse leadership?

Featuring: Emily Reichert, CEO of Greentown Labs, which is opening a location in Houston this year.

The event takes place at 11:30 am on Tuesday, March 2. Learn more.

Wednesday — Rice Alliance Venture Day at CERAWeek

The Rice Alliance for Technology and Entrepreneurship pitch event will showcase 20 technology companies with new solutions for the energy industry. Each presentation will be followed by questions from a panel of industry experts.

Presenting Companies: Acoustic Wells, ALLY ENERGY, Bluefield Technologies, Cemvita Factory, Connectus Global, Damorphe, Ovopod Ltd., DrillDocs, GreenFire Energy, inerG, Locus Bio-Energy Solutions, Nesh, Pythias Analytics, REVOLUTION Turbine Technologies, Revterra, ROCSOLE, Senslytics, Subsea Micropiles, Syzygy Plasmonics, Transitional Energy, and Universal Subsea.

The event takes place at 9 am on Wednesday, March 3. Learn more.

Thursday — How Will the Energy Innovation Ecosystem Evolve?

Although the cleantech innovation ecosystem—research institutions, entrepreneurs, financiers, and support institutions—is diverse and productive, converting cleantech discoveries and research breakthroughs into commercially viable, transformative energy systems has proven difficult. With incumbent energy systems economically efficient and deeply entrenched, cleantech innovation faces a fundamental dilemma—the scale economies necessary to compete require a large customer base that does not yet exist. How is our clean energy innovation ecosystem equipped to be transformative? What needs to be strengthened? Is it profitable to focus on individual elements, or should we consider the system holistically, and reframe our expectations?

Featuring: Barbara Burger, vice president of innovation at Chevron and president at Chevron Technology Ventures

The event takes place at 7:30 am on Thursday, March 4. Learn more.

Friday — Cities: Managing crises & the future of energy

Houston is the capital of global energy and for the past four decades the home of CERAWeek. Mayor Sylvester Turner will share lessons from the city's experience with the pandemic, discuss leadership strategies during times of crisis, and explore Houston's evolving role in the new map of energy.

The event takes place at 8 am on Friday, March 5. Learn more.

Intuitive Machines lands $600M satellite deal, NASA ‘spacecraft bus’ contract

space deals

Houston-based space infrastructure company Intuitive Machines has scored two astronomical deals.

The deals add to the company’s soaring success. As of June 30, Intuitive Machines had a record-high $1.8 billion backlog of orders, a $1.5 billion increase from the end of last year. The current backlog includes orders for more than 80 spacecraft.

The company, which went public in 2023, expects this year’s revenue to total $900 million to $1 billion. In the first half of 2026, Intuitive Machines generated nearly $393 million in revenue.

Intuitive Machines estimates its total available market is valued at more than $150 billion.

$600 million-plus deal represents ‘important milestone’

On Monday, Intuitive Machines said it picked up a $600 million-plus deal to develop three commercial satellites for an undisclosed customer over the course of about two years.

Intuitive Machines says it will design, manufacture, set up and support several spacecraft “for a critical communications infrastructure mission.”

Steve Altemus, the company’s CEO, says the deal represents “an important milestone for Intuitive Machines and reflects the confidence our customers place in our ability to deliver high-performance spacecraft for a broad range of mission needs.”

Company nails down NASA deal for ‘spacecraft bus’

A day after announcing the $600 million-plus deal, Intuitive Machines said it secured a new contract with NASA.

Intuitive Machines says NASA’s Jet Propulsion Laboratory in Southern California will use the company’s IM 300 “spacecraft bus” for an EAGLE-VSWIR Earth observation mission. The mission is scheduled to launch in 2028.

Aside from supplying the IM 300 bus, Intuitive Machines will carry out mission support services.

The low-Earth-orbit mission will be equipped with Intuitive Machines’ hyperspectral visible to shortwave infrared (VSWIR) instrument. This technology sees colors and details that aren’t visible to the human eye.

The instrument is “designed to perform surface biology and geology observations from Earth orbit while demonstrating technologies that could support future lunar and Mars exploration missions,” Intuitive Machines says.

Intuitive Machines builds mission-critical spacecraft, systems, and infrastructure for business and government customers. To date, the company has produced more than 300 spacecraft, delivered over 575 pounds of payload to the moon and launched about 100 satellites.

9 Houston-based companies make Fortune Global 500 list in 2026

Worldwide Rankings

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.

Fast-growing Houston real estate startup surges to No. 7 on Inc. 5000

growth report

Houston-based Epique Realty has ridden the AI wave to rank among the Inc. 5000’s 10 fastest-growing private companies.

With three-year revenue growth of 23,210 percent, the AI-powered real estate brokerage appears at No. 7 on this year’s Inc. 5000 list. The 2026 list ranks private companies based on percentage revenue growth from 2022 to 2025.

Epique, founded in 2021, also ranks as the No. 1 fastest-growing company in Houston, No. 1 fastest-growing real estate company in the U.S., and No. 2 fastest-growing company in Texas.

Epique’s annual revenue surpasses $91 million

Between 2022 and 2025, the company’s annual revenue skyrocketed from $391,654 to more than $91.2 million. In 2025, the brokerage closed more than 23,000 deals and surpassed $7 billion in total sales, elevating Epique to the country’s 14th-largest real estate brokerage as measured by volume.

Epique’s network has more than 4,000 agents.

“To debut in the top 10 of the Inc. 5000 is absolute proof that when you relentlessly put agents first, exponential growth takes care of itself,” co-founder and CEO Joshua Miller said in a news release.

“We didn’t achieve this by following the industry playbook; we achieved this by burning it,” Miller added. “By fully funding our agents’ success through free health care, proprietary AI, and world-class leads, we’ve built a company where agents can finally thrive.”

The company’s other co-founders are Chris Miller, chief operating officer and vice president of expansion, and Janice Delci, chief financial officer.

Epique expands business to Canada, Mexico, Australia

The Millers and Delci have guided the company’s rapid expansion.

“Scaling our corporate support team to match [our] hyper-growth while seamlessly expanding across all 50 states and internationally to Canada, Australia, and Mexico takes an incomparable operational infrastructure,” Miller said.

“We have built an enterprise-grade technology ecosystem that allows us to absorb overhead and empower our agents at lightning speed,” he added. “This ranking validates that our disruptive model is working, and it is completely redefining the global industry standard.”

Epique launched its platform in 2023, touting itself as the industry’s first AI-powered brokerage. The startup’s platform provides AI tools for real estate agents to improve their marketing, streamline content creation, and boost engagement with clients and prospects.

Among Epique’s AI tools are:

  • ChatGPT for generation of property descriptions
  • AI-assisted creation of blog posts and agents’ bios
  • Production of Instagram quotes for social media marketing

“When we started Epique, we wanted to build a company that genuinely cared for its agents’ financial and physical well-being,” Delci says. “To see that vision translate into this level of historic record-breaking growth is a beautiful testament to the true power of radical generosity.”

Epique and fellow honorees will be recognized Oct. 14-16 at the 2026 Inc. 5000 Conference & Gala in Dallas.
