More than a dozen Houston-based companies are sharing the spotlight in U.S. News and World Report's collection of the "Best Companies to Work For" in 2024-2025, including several of the Bayou City’s energy companies.

The annual report examines publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2024-2025 report, U.S. News analyzed 549 companies across 29 different lists, including the overall best companies list — which includes the best 300 companies across the U.S., the United Kingdom, Ireland, Switzerland, Luxembourg, and Bermuda — 24 industry-specific lists, and four regional lists.

There were 16 total companies based around Houston that made the lists, with the majority being based in the city, while one each were located in Spring and The Woodlands.

Independent energy company Marathon Oil was the top-rated Houston energy employer, with nearly 1,700 employees, an annual revenue stream of $6.38 billion, and a $15.4 billion market cap. The company was specifically highlighted with a "Top Quality of Pay" label, but also boasts high ratings for its employees' work-life balance, job stability, and belongingness.

In addition to being included in the overall "Best Companies" list, Marathon Oil earned recognition in the industry-specific "Best in Energy" list and the "Best Companies in the South" list.

A second Houston-based energy company earning a spot among the top employers is Occidental (also known as Oxy). The petroleum corporation, which has been in operation since 1920, has nearly 12,600 employees and brings in $27,43 billion in revenue every year.

According to U.S. News, Occidental offers many financial, health and wellness, and workplace benefits including 401k matching, tuition assistance, an employee assistance program, flexible work arrangements, and much more. The company was also given a "Top Quality of Pay" designation.

Occidental appeared in U.S. News' "Best in Mining and Raw Materials," the overall "Best Companies," and "Best Companies in the South" lists.

The other top energy employers include:

  • Southwestern Energy Company, Spring – Best in Energy; Best Companies (overall); Best Companies in the South
  • ConocoPhillips – Best in Energy, Best Companies in the South
  • Cheniere – Best in Energy
  • EOG Resources – Best in Energy
  • Murphy Oil Corporation – Best in Energy

"Prospective and current employees understand the significant impact their employer has on their quality of life," said Carly Chase, vice president of careers at U.S. News and World Report, in a release. "Whether a new grad seeking a company to launch their career, an established professional looking for a change or an HR professional researching the strengths of their company and others, Best Companies to Work For provides a central space to see which companies are meeting their employees' needs best.

EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.

Houston climatech startup raises $29M funding round​

fresh funding

Houston-based NanoTech Materials has closed a $29.4 million Series A.

The round was led by Austin-based HPI Real Estate & Investments. Houston-based Goose Capital and Austin-based Milliken & Company also participated.

Nanotech has developed its patented Insulative Ceramic Particle (ICP) technology, which reduces heat transfer in buildings and outdoor infrastructure, improving efficiency and safety. It's known for its Cool Roof Coat, Wildfire Shield and Insulative Coat: Cool Touch product lines.

With the new funding, Nanotech plans to scale operations and expand its market reach for its products.

“We’re addressing one of the pressing and urgent challenges facing infrastructure owners today: controlling energy costs and extending asset life,” Mike Francis, CEO and co-founder of NanoTech Materials, said in a news release. “This financing marks a transformative moment for us. It allows us to rapidly scale production and bring our high-performance materials to market faster, while delivering measurable cost savings and redefining what resilience looks like in today’s built environment.”

Nanotech launched in 2020 and was the first company selected for Halliburton Labs. It moved into a 43,000-square-foot space in Katy in 2023. It brought on new partners that expanded the company's reach in the Middle East and Singapore the following year. Its technology was recognized as one of Time magazine's 200 Best Inventions of 2024.

“We were early investors in Nanotech Materials and are pleased to continue supporting the company as it becomes a leader in breakthrough materials science and technology,” John Chaney, investor at Goose Capital and board member at NanoTech, added in the release. “NanoTech’s ability to elevate fire resilience and energy efficiency in the built environment is critical for strengthening and hardening infrastructure. Its pioneered approach is transforming current building standards and making our lives safer.”

The company has secured $34.4 million in total to date, according to the release. It raised an oversubscribed funding round in 2023 and a $5 million seed round in 2020.

Houston clean energy startup acquired by battery storage company FlexGen

m&a activity

A North Carolina company has acquired Houston-based Clean Energy Services, a provider of services for battery energy storage systems and utility-scale solar, for an undisclosed amount.

The buyer is Durham, North Carolina-based FlexGen Power Systems, a provider of battery energy storage software and services.

Clean Energy Services (CES), whose offices are at the Ion, will operate as a subsidiary of FlexGen. Existing CES customers will continue to receive services from CES without disruption or change, FlexGen says.

“Demand for reliable, high-performance power is accelerating, and customers need partners who can deliver at scale,” Kelcy Pegler, CEO of FlexGen, said in a news release. “The addition of CES strengthens our service platform and reinforces our leadership in energy storage technology.”

Ahmad Atwan and Constantine Triantafyllides co-founded CES in 2022. As a startup, CES had raised $8 million in venture capital, according to PitchBook.

“CES has achieved a market leadership position in battery storage services by focusing on reliable speed of service delivery and optimizing asset performance,” Atwan, the company’s CEO, added the release. “FlexGen and CES have been strong partners for years, and this transaction enables us to deliver more robust solutions across a complementary set of customers and markets.”

CES will continue to operate its remote operations center in Houston for over 1 gigawatt of solar assets and 4.5 gigawatt-hours of battery assets, while FlexGen will maintain its remote operations center in Durham.
