Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow. The collaborative community offers members state-of-the-art prototyping labs, business resources and access to investors and corporate partners. The co-located incubator was first launched in Boston in 2011 before opening in Houston in 2021.

Greentown has seen major changes and activity this year. In February, Greentown announced Georgina Campbell Flatter as its new CEO, along with a new Board of Directors. In July, it announced Lawson Gow as its Head of Houston, a "dedicated role to champion the success of Greentown Houston’s startups and lead Greentown’s next chapter of impact in the region," according to Greentown. It has since announced numerous new partnerships, including those with Energy Tech Nexus, Los Angeles-based software development firm Nominal, to launch the new Industrial Center of Excellence; and Houston-based Shoreless, to launch an AI lab onsite.

Uber rolls out women-only ride preferences to Houston users

Women Preferences

Houston women riders and drivers can now be matched to other women on the Uber app. The ride-hailing giant has expanded its pilot program nationwide in response to customer safety concerns.

“When women riders and drivers told us they wanted more control over how they ride and earn, we listened,” wrote Uber in a blog post announcing the move. “That feedback led to Women Preferences, features designed to give women the choice to ride with other women. Since our first pilots last summer, we’ve heard just how much that choice matters — from feeling more comfortable in the back seat to more confident behind the wheel.”

According to Uber, passengers can request to be matched with a woman driver by requesting an on-demand ride, scheduling a trip in advance, or setting a preference within the ride app. If wait times are longer than anticipated, the rider can opt to be paired with a driver of any sex.

Uber says it began offering the rides in 2019, after women in Saudi Arabia gained the right to drive. Since then, it has rolled out the program in Europe, Latin America, Australia, and Africa — although in some countries, only drivers can make the match.

The move forward on Women Preferences comes despite a pair of lawsuits aimed at Uber and its main competitor, Lyft. According to Time reporting, the plaintiff’s lawyers argue that women-only rides unfairly limit the volume of rides for male drivers and reinforce gender stereotypes about men.

Lyft rolled out its similar program, Women + Connect, in 2023. The initiative is slightly more expansive than Uber’s preferences, allowing both women and nonbinary people to participate.

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.
