Greentown Labs has named the six participating climatetech startups for an accelerator for a global energy leader.

Shell and Greentown Labs announced the cohort for Greentown Go Make 2023 — a program designed to accelerate partnerships between startups and corporates to advance carbon utilization, storage, and traceability solutions with manufacturing in mind. Shell, which invests in net-zero and carbon-removal technologies, is hoping to strategically align with startups within carbon utilization, storage, and traceability across the energy transition spectrum.

“At Greentown Labs we recognize and appreciate the role energy incumbents must play in the energy transition, and we’re eager to facilitate meaningful partnerships between these impressive startups and Shell—not only to advance these technologies but also to help Shell achieve its sustainability goals,” Kevin Knobloch, CEO and President of Greentown Labs, says in a news release. “We know carbon utilization, storage, and traceability will play a critical role in our collective efforts to reach net-zero, and we’re enthusiastic about the potential impact these companies can have in that work.”

The cohort, selected from 110 applications, is co-located at Greentown's Houston and Somerville, Massachusetts, locations and includes:

  • Portland-based Caravel Bio is developing a novel synthetic biology platform that uses microbial spores and enzymes to create catalysts that are long-lasting and can withstand extreme conditions and environments.
  • Circularise, which is based in the Netherlands, is developing a blockchain platform that provides digital product passports for end-to-end traceability and secure data exchange for industrial supply chains.
  • Corumat, based in Washington, converts organic waste into high-performance, insulating, greaseproof, and biodegradable packaging materials.
  • Cambridge, Massachusetts-headquartered Lydian develops a fully electrified reactor that can convert a variety of gaseous, non-fossil feedstocks into pure syngas with high efficiency.
  • Maple Materials from Richmond, California is developing a low-cost electrolysis process to split carbon dioxide into graphite and oxygen.
  • Ontario, Canada-founded Universal Matter develops a proprietary Flash Joule Heating process that converts carbon waste into high-value and high-performance graphene materials to efficiently create sustainable circular economies.

The program, which includes $15,000 in non-dilutive stipend funding for each company, will work closely with Shell and Greentown over six months via mentorship, networking opportunities, educational workshops, and partnership-focused programming to support collaboration. Go Make 2023 concludes with a showcase event on March 27 at Greentown Labs’ Houston location.

This week, Shell announced another accelerator cohort it's participating in. The Shell GameChanger Accelerator, a partnership with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), named four West Coast climatetech companies: DTE Materials, Hexas Biomass, Invizyne Technologies, and ZILA BioWorks. The program provides early-stage cleantech startups with access to experts and facilities to reduce technology development risk and accelerate commercialization of new cleaner technologies.

“Tackling the climate challenge requires multifaceted solutions. At Shell, we believe technology that removes carbon dioxide from the atmosphere will be essential for lowering emissions from energy and chemical products,” Yesim Jonsson, Shell’s GCxN program manager, says in a statement. “The companies in GCxN's sixth cohort embody these objectives and have the potential to usher in a more sustainable future.”

6 Houston entrepreneurs land on coveted Inc. Female Founders 500 list

the future is female

Six Houston female entrepreneurs and innovators were named to the 2026 Female Founders 500 list.

The annual list compiled by Inc. Magazine recognizes female founders based in the U.S. who have built businesses that have moved their industries forward. The group collectively generated approximately $12.3 billion in 2025 revenue and $12.2 billion in funding to date, according to Inc. Five Houstonians were named to the list last year.

"Each year, we are increasingly amazed by the extraordinary leaders on our Inc. Female Founders 500 list," Bonny Ghosh, editorial director at Inc., said in a news release. "The honorees on this year's list include innovators in AI, beauty and wellness trendsetters winning devoted fans, and nonprofit leaders making a real impact in their communities. Together, they're showing all of us what trailblazing female leadership looks like."

The Houston founders are:

  • Sassie Duggleby, CEO and co-founder of Houston space tech and engine company Venus Aerospace. Duggleby also serves on the Texas Space Commission board of directors.
  • Stephanie Murphy, CEO and executive chairman of Aegis Aerospace, which provides space services, spaceflight product development, and engineering services. Murphy also serves as chair of the Texas Aerospace Research and Space Economy Consortium Executive Committee.
  • Laureen Meroueh, CEO and founder of Hertha Metals, which has developed a cost-effective and energy-efficient process that converts low-grade iron ore of any format directly into molten steel or high-purity iron in a single step.
  • LaToshia Norwood, managing partner of L'Renee & Associates (LRA), a full-service project management consulting firm.
  • Lauren Rottet, president and founding principal of Rottet Studio, an international architecture and design firm focused on corporate, lifestyle and hospitality projects
  • Nina Magon, founder and CEO of Nina Magon Studio / Nina Magon Consumer Products, a residential and commercial interior design company. She also co-founded KA Residences earlier this year.

"Grateful to be recognized again on the Inc. Female Founders 500," Duggleby said in a LinkedIn post. "The best part of building Venus Aerospace has been working with an incredible team pushing the boundaries of flight—and helping bring more women into aerospace along the way.

Meroueh, whose company emerged from stealth last year, voiced a similar push for bringing more women into the fold.

"We've seen a 7x jump in female-led IPOs over the last decade, from just two in 2014 (less than 1% of all IPOs) to 14 in 2024 (nearly 9% of all IPOs). Progress is happening," Meroueh shared in a LinkedIn post. "Yet, less than 1% of venture funding in hard tech goes to female-founded companies. But as my friend Ana Kraft says, the right man for the job may be a woman."

Twenty-nine Texas female founders made this list, including Amber Venz Box, founder of the Dallas-based LTK shopping platform, and Cheryl Sew Hoy, CEO and founder of Austin-based Tiny Health, a fast-growing at-home microbiome health platform. See the full list of winners here.

NASA clears Artemis moon rocket for April launch with 4 astronauts

3, 2, 1...

NASA has cleared its moon rocket on for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

The space agency has only six days at the beginning of April to launch before standing down until April 30 into early May.

"It's a test flight and it is not without risk, but our team and our hardware are ready,” NASA's Lori Glaze told reporters at the end of the two-day flight readiness review.

Glaze and other NASA officials declined to provide the risk probabilities for the upcoming mission.

History has shown that a new rocket has essentially a 50% chance of success, said John Honeycutt, chair of the mission management team.

There's so much gap since the only other SLS flight — more than three years ago without anyone on board — that it's difficult to understand any risk assessment numbers, Honeycutt said.

“It's not the first flight," Glaze said. "But we're also not in a regular cadence. So we definitely have significantly more risk than a flight system that's flying all the time.”

Late last month NASA's new administrator, Jared Isaacman, announced a major overhaul of the Artemis program to speed things up and, by doing so, reduce risk.

Dissatisfied with the slow pace and lengthy gaps between lunar missions, he added an extra practice flight in orbit around Earth for next year. That is now the new Artemis III, with the moon landing by two astronauts shifted to Artemis IV. Isaacman is targeting one and maybe even two lunar landings in 2028.

NASA's Office of Inspector General warned in an audit that the space agency needs to come up with a rescue plan for its lunar crews. Landing near the moon's south pole will be riskier than it was for the Apollo astronauts closer to the equator given the rough polar terrain, according to the report.

The report cited the lunar landers as the top contributor for potential loss of crew during the first few Artemis moon landings. It listed the space agency’s loss-of-crew threshold at 1-in-40 for lunar operations and 1-in-30 for Artemis missions overall.

Contracted by NASA to provide the moon landers for astronauts, Elon Musk's SpaceX and Jeff Bezos' Blue Origin have accelerated work in order to meet the new 2028 target date. The inspector general's office said many technical challenges remain including refueling their landers in orbit around Earth before flying to the moon.

NASA sent 24 astronauts to the moon during Apollo, 12 of whom landed on it. All but one of the moonshots — Apollo 13 — achieved their prime objectives. The program ended with Apollo 17 in 1972.

Kinder leads 19 Houstonians on Forbes' World's Billionaires List 2026

World's Richest 2026

According to Forbes, there has “never been a better time to be a billionaire” than in 2026, and the publication's newest World’s Billionaires List has revealed the 19 Houston billionaires that have risen among the wealthiest worldwide.

Kinder Morgan chairman Richard Kinder surpassed hospitality honcho Tilman Fertitta as the richest billionaire in Houston, ranking No. 232 on the global list with an estimated net worth of $13 billion. His net worth has grown by $2.4 billion since last year.

Fertitta, 68, may not be the richest Houstonian anymore, but his wealth is still on the rise. He ranked 268th on the list with an estimated net worth of $11.7 billion, up from $11.3 billion last year.

Out of the 390 billionaire newbies that made their debut onto the list this year, one of them calls Houston home: restaurateur and commodities trader Ignacio Torras. Torras, 61, is the founder and CEO of global commodities trading company Tricon Energy, and he owns Michelin-starred local restaurant BCN Taste & Tradition and its sister eatery MAD. But that's not all he spends his time doing, according to Forbes.

"In 2024 Torras launched a soccer tournament for neurodivergent players called the Genuine Cup," his profile said. "Last year 800 players and 30 teams from around the world played at Rice University stadium."

Torras debuted as No. 2600 on the list with an estimated net worth of $1.5 billion.

Houston-born multi-hyphenate superstar Beyoncé Knowles-Carter also staked a claim among the world's richest people in 2026. She ranked No. 3332 on the list with a net worth of $1 billion, thanks to her "years of music sales, touring and collecting art with her already-billionaire husband Jay-Z (estimated net worth: $2.8 billion)," Forbes said.

"The majority of pop star Beyonce’s net worth comes from her roughly three decades as a solo performer and a member of the girl-group Destiny's Child," her profile said. "She holds the record for the most Grammy wins ever, with 35, and won her first Album of the Year trophy in 2025. She and her billionaire husband Jay-Z purchased a $200 million Malibu mansion in 2023, in what was the most expensive home sale in California history."

Beyoncé also ranks No. 21 in the publication's separate list of The World's Celebrity Billionaires.

Here's how the rest of Houston's billionaires fared on this year's list:

  • Toyota mega-dealer Dan Friedkin: No. 279; $11.4 billion, up from $7.7 billion
  • Pipeline heir Randa Duncan Williams: tied for No. 323 with an estimated net worth of $10.2 billion, up from $9.3 billion in 2025. Fellow pipeline heirs Dannine Avara and Milane Frantz tied for No. 332 globally. Each has an estimated net worth of $10.1 billion, up from $9.2 billion. Scott Duncan ranks No. 353 with a $9.8 billion estimated net worth, up from $9 billion in 2025.
  • Oil tycoon Jeffery Hildebrand: No. 341; $10 billion, up from $7.7 billion
  • Houston Texans owner Janice McNair and family: No. 528; $7.3 billion, up from $6.2 billion

  • Mercedes-Benz mega-dealer Joe Agresti: No. 3185; $1.1 billion, flat from 2025
  • Frontier Airlines chairman William Franke: No. 3332; $1 billion, down from $1.2 billion

Elsewhere in Texas

Austin billionaire Elon Musk was declared the world's richest person for the second consecutive year, and Forbes said his “grip on the top spot is as strong as it’s ever been.”

“Musk became the first person to hit $500 billion in wealth, in October,” Forbes said. “Then $600 billion and $700 billion, within four days in December. Then $800 billion, in February.”

The Tesla, SpaceX, and xAI founder’s current net worth has skyrocketed to $839 billion — a shocking $497 billion more than his 2025 net worth.

In Dallas-Fort Worth, Walmart heiress Alice Walton has maintained her elite status as the world’s richest woman for the third year in a row. Walton is the 14th richest person on the planet with a current net worth of $134 billion, an eye-catching $33 billion higher than her 2025 net worth. She is the first American woman worth $100 billion, and one of only 20 “centi-billionaires” worldwide claiming 12-figure fortunes, also known as the "$100 Billion Club."

Koch Inc. stakeholder Elaine Marshall and her family are the richest Dallas residents, ranking No. 71 globally with an estimated net worth of $30.9 billion. Her net worth has grown by $2.6 billion since last year.
