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. Greentown Houston has supported 175 startups since its launch in 2021, with 45 joining in the last two years. Those startups include the likes of Hertha Metals, RepAir Carbon, Solidec, Eclipse Energy (formerly GoldH2) and many others.

Healthtech Accelerator (TMCi)

The Healthtech Accelerator, formerly TMCx, focuses on clinical partnerships to improve healthcare delivery and outcomes. Emerging digital health and medical device startups that join the accelerator are connected with a network of TMC hospitals and seasoned advisors that will prepare them for clinical validation, funding and deployment.

The Healthtech Accelerator is part of Texas Medical Center Innovation, which also offers the TMCi Accelerator for Cancer Therapeutics. The Healthtech Accelerator named its 19th, and latest, cohort of 11 companies last month.

Impact Hub Houston

Impact Hub Houston supports early-stage ventures at various stages of development through innovative programs that address pressing societal issues. The nonprofit organization supports social impact startups through mentorship, connections and training opportunities.

There are more than 110 Impact Hubs globally with 24,000-plus members spanning 69 countries, making it one of the world’s largest communities for accelerating entrepreneurial solutions toward the United Nations' Sustainable Development Goals (SDGs).

Greentown Labs names new CEO to lead pioneering climate tech incubator

Transition News

Houston and Boston climate tech incubator Greentown Labs has named Georgina Campbell Flatter as the organization’s incoming CEO.

Flatter will transition to Greentown from her role as co-founder and executive director of TomorrowNow.org, a global nonprofit that studies and connects next-generation weather and climate technologies with communities most affected by climate change.

“We are at a transformational moment in the energy transition, with an unprecedented opportunity to drive solutions in energy production, sustainability, and climate resilience,” Flatter said in a news release. “Greentown Labs is, and has always been, a home for entrepreneurs and a powerhouse of collaboration and innovation.”

Previously, Flatter worked to launch TomorrowNow out of tomorrow.io, a Boston-based AI-powered weather intelligence and satellite technology company. The organization secured millions in climate philanthropy from partners, including the Gates Foundation, which helped deliver cutting-edge climate solutions to millions of African farmers weekly.

Flatter also spent 10 years at the Massachusetts Institute of Technology (MIT), where she was a senior lecturer and led global initiatives at the intersection of technology and social impact.

“It’s rare to find an individual who has impressive climate and energy expertise along with nonprofit and entrepreneurial leadership—we’re fortunate Georgie brings all of this and more to Greentown Labs,” Bobby Tudor, Greentown Labs Board Chair and Chairman of the Houston Energy Transition Initiative, said in a news release.

Flatter will collaborate with Kevin Dutt, Greentown’s Interim CEO, and also continue to serve on Greentown’s Board of Directors, which was recently announced in December and contributed to a successful $4 million funding round. She’s also slated to speak at CERAWeek next month.

“In this next chapter, I’m excited to build on our entrepreneurial roots and the strength of our ever-growing communities in Boston and Houston,” Flatter added in a news release. “Together, we will unite entrepreneurs, partners, and resources to tackle frontier challenges and scale breakthrough technologies.”

Greentown also named Naheed Malik its new chief financial officer last month. The announcements come after Greentown’s former CEO and president, Kevin Knobloch, announced that he would step down in July 2024 after less than a year in the role.

CPRIT CEO: Houston’s $2B in funding is transforming cancer research and prevention

fighting cancer

With its plethora of prestigious health care organizations like the University of Texas MD Anderson Cancer Center, UTHealth Houston, and the Baylor College of Medicine, Houston sits at the heart of cancer research and prevention in Texas.

Of course, it takes piles of cash to support Houston’s status as the state’s hub for cancer research and prevention. Much of that money comes from the Cancer Prevention and Research Institute of Texas (CPRIT).

Data supplied by CPRIT shows organizations in Harris County gained $2.3 billion in institute funding from 2009 through 2025, or nearly $145 million per year. That represents almost 60 percent of the roughly $4 billion that CPRIT has granted to Texas institutions over a 16-year period.

“The life sciences ecosystem that has developed and changed in Houston is phenomenal,” Kristen Doyle, who became the agency’s CEO in July 2024, tells InnovationMap. “In the next decade, we will look back and see a great transformation.”

That ecosystem includes more than 1,100 life sciences and biotech companies, according to the Greater Houston Partnership.

Houston plays critical role in clinical trials

Texas voters approved the creation of CPRIT in 2007. Twelve years later, voters agreed to earmark an extra $3 billion for CPRIT, bringing the state agency’s total investment in cancer research and prevention to $6 billion.

To date, CPRIT money has gone toward recruiting 344 cancer researchers to Texas (mainly to Houston) and has supported cancer prevention services for millions of Texans in the state’s 254 counties. CPRIT funding has also helped establish, expand, or relocate 25 cancer-focused companies. In Houston, MD Anderson ranks as the No. 1 recipient of CPRIT funding.

Regarding cancer research, Doyle says Houston plays a critical role in clinical trials.

“[Clinical trials are] something that CPRIT has focused on more and more. Brilliant discoveries are crucial to this whole equation of solving the cancer problem,” Doyle says. “But if those brilliant ideas stay in the labs, then we’ve all failed.”

Researchers conduct more clinical trials in Houston than anywhere else in the U.S., the Greater Houston Partnership says.

Doyle, a 20-year survivor of leukemia, notes that a minority of eligible patients participate in clinical trials for cancer treatments, “and that’s one of the reasons that it takes so long to get a promising drug to market.”

An estimated 7 percent of cancer patients sign up for clinical trials, according to a study published in 2024 in the Journal of Clinical Oncology.

MD Anderson takes on cancer prevention

Doyle also notes that Houston is leading the charge in cancer prevention.

“We get some national recognition for programs that have been developed in Houston that then can be replicated in other parts of the country,” she says.

Much of the work in Houston focusing on cancer prevention takes place at MD Anderson. The hospital reports that it has received more than $725 million from the CPRIT since 2007, representing approximately 18 percent of CPRIT’s total awards.

“These efforts can have profound impact on the lives of patients and their families, and this funding ensures our exemplary clinicians and scientists can continue working together to drive breakthroughs that advance our mission to end cancer,” Dr. Giulio Draetta, chief scientific officer at MD Anderson, said in a November news release, following the most recent CPRIT award for the hospital totaling more than $29 million.

CPRIT funding for Houston institutions supplements the more than $4.5 billion in federal funding for health and life sciences research and innovations that the Houston area received from 2020 to 2024, according to the Greater Houston Partnership.

“We are curing cancer every single day,” Doyle says of CPRIT. “Every step that we are taking — whether that’s funding great ideas or funding the clinical trials that are bringing promising drugs to Texas and to the world — we are making a difference.”

Houston energy tech co. breaks ground on low-cost hydrogen pilot plant

Coming Soon

Houston’s Lummus Technology and Advanced Ionics have broken ground on their hydrogen pilot plant at Lummus’ R&D facility in Pasadena, Texas.

The plant will support Advanced Ionics’ cutting-edge electrolyzer technology, which aims to deliver high-efficiency hydrogen production with reduced energy requirements.

“By demonstrating Advanced Ionics’ technology at our state-of-the-art R&D facility, we are leveraging the expertise of our scientists and R&D team, plus our proven track record of developing breakthrough technologies,” Leon de Bruyn, president and CEO of Lummus, said in a news release. “This will help us accelerate commercialization of the technology and deliver scalable, cost-effective and sustainable green hydrogen solutions to our customers.”

Advanced Ionics is a Milwaukee-based low-cost green hydrogen technology provider. Its electrolyzer converts process and waste heat into green hydrogen for less than a dollar per kilogram, according to the company. The platform's users include industrial hydrogen producers looking to optimize sustainability at an affordable cost.

Lummus, a global energy technology company, will operate the Advanced Ionics electrolyzer and manage the balance of plant systems.

In 2024, Lummus and Advanced Ionics established their partnership to help advance the production of cost-effective and sustainable hydrogen technology. Lummus Venture Capital also invested an undisclosed amount into Advanced Ionics at the time.

“Our collaboration with Lummus demonstrates the power of partnerships in driving the energy transition forward,” Ignacio Bincaz, CEO of Advanced Ionics, added in the news release. “Lummus serves as a launchpad for technologies like ours, enabling us to validate performance and integration under real-world conditions. This milestone proves that green hydrogen can be practical and economically viable, and it marks another key step toward commercial deployment.”
