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.

Houston Methodist awarded $4M grant to recruit head of Neal Cancer Center

new hire

Armed with a $4 million state grant, the Houston Methodist Academic Institute has recruited a renowned expert in ovarian and endometrial cancer research to lead the Dr. Mary and Ron Neal Cancer Center.

The grant, provided by the Cancer Prevention and Research Institute of Texas, enabled the institute to lure Dr. Daniela Matei away from Northwestern University’s Feinberg School of Medicine in Chicago. There, she is the Diana Princess of Wales Professor in Cancer Research and chief of the Division of Reproductive Science in Medicine.

Matei will succeed Dr. Jenny Chang, who was hired last year to run the Houston Methodist Academic Institute.

At the Neal Cancer Center, located in the Texas Medical Center complex, oncologists work on innovations in cancer research, treatment, and technology. The center opened in 2021 after the Neals donated $25 million to expand Houston Methodist’s cancer research capabilities. It handles about 7,000 new cases each year involving more than two dozen types of cancer.

U.S. News & World Report puts Houston Methodist Hospital at No. 19 among the country’s best hospitals for cancer care, two spots below Chicago’s Northwestern Memorial Hospital. The University of Texas MD Anderson Cancer Center in Houston sits at No. 1 on the list.

Matei’s research related to ovarian and endometrial cancer holds the potential to benefit tens of thousands of American women. The American Cancer Society estimates:

  • 21,010 women in the U.S. will be diagnosed with ovarian cancer, and 12,450 women will die from it.
  • 68,270 women in the U.S. will be diagnosed with endometrial cancer, and 14,450 women will die from it.

Matei is leaving Northwestern in the wake of widespread cuts in federal funding for medical research. The National Institutes of Health (NIH) has canceled or frozen tens of millions of dollars in grants for Northwestern, the Wall Street Journal reports, and the university has been plugging the gaps with its own money.

“The university is totally keeping us on life support,” Matei told the newspaper last year. “The big question is for how long they can do this.”

According to the Wall Street Journal, Matei’s $5 million NIH grant supporting 69 cancer trials has been caught up in the federal funding chaos, so Northwestern stepped in to cover trial expenses such as nurses’ salaries and diagnostic procedures.

Trial participants include some patients with rare, incurable tumors who are undergoing experimental treatments aligned with the genetics of their condition, the newspaper says.

“It’s certainly a life-and-death situation for cancer patients on these trials,” Matei said in 2025.

Matei is among the beneficiaries of more than $15 million in grants approved February 18 by CPRIT’s board. The grants went toward recruiting five cancer researchers to institutions in Texas.

One of those grants, totaling $1.5 million, went to the University of Houston to recruit Akash Gupta, a research scientist at MIT’s Koch Institute for Integrative Cancer Research. The remaining grants went to recruit scientists to The University of Texas at Dallas and The University of Texas Southwestern Medical Center.

Rice University lands $14M state grant to open Center for Space Technologies

on a mission

Rice University’s Space Institute soon will be home to the newly created Center for Space Technologies.

On Feb. 17, the Texas Space Commission approved a nearly $14.2 million grant for the Rice project. The Center for Space Technologies will target:

  • Research and development
  • Technology transfer and innovation
  • Statewide partnerships
  • Workforce development training
  • Space-focused education programs

The goal of the new center “is to fulfill an articulated need for research, workforce development, and industry collaboration,” said Kemah communications and marketing executive Gwen Griffin, chair of the commission.

State Rep. Greg Bonnen, a Friendswood Republican, authored the bill that set up the Texas Space Commission.

Since being authorized in 2023, the commission has funded 24 projects, with Rice and Houston-area companies accounting for nearly $75 million in grants to back space-related initiatives.

The grant to Rice brings the TSC's total investment to $150 million, fully committing the entire state appropriation from the Texas Legislature in 2023.

Other local companies that have received grants over the years include Aegis Aerospace, Axiom Space, Intuitive Machines, Starlab Space and Venus Aerospace.

The commission also awarded $7 million to Blue Origin earlier this month. See a list of the 24 awards here.

Waymo self-driving robotaxis have officially launched in Houston

Waymo has arrived

Waymo will begin dispatching its robotaxis in four more cities in Texas and Florida, expanding the territory covered by its fleet of self-driving cars to 10 major U.S. metropolitan markets.

The move into Dallas, Houston, San Antonio and Orlando, Florida, announced Tuesday, February 24, widens Waymo's early lead in autonomous driving while rival services from Tesla and the Amazon-owned Zoox are still testing their vehicles in only a few U.S. cities.

In contrast, Waymo's robotaxis already provide more than 400,000 weekly trips in the six metropolitan areas where they have been transporting passengers: Phoenix, the San Francisco Bay Area, Los Angeles, Miami, Atlanta, and Austin, Texas.

Waymo operates its ride-hailing service through its own app in all the U.S. cities except Atlanta and Austin, where its robotaxis can only be summoned through Uber's ride-hailing service.

The expansion into four more markets marks a significant step toward Waymo's goal to surpass 1 million weekly paid trips by the end of 2026. Without identifying where its robotaxis will be available next, Waymo is targeting a list of eight other cities that include Las Vegas, Washington, Detroit and Boston while signaling its first overseas availability is likely to be London.

To help pay for more robotaxis, Waymo recently raised $16 billion as part of the financial infusion that puts the value of the company at $126 billion. The valuation fueled speculation that Waymo may eventually be spun off from its corporate parent Alphabet, where it began as a secret project within Google in 2009.

Although Waymo is opening up in four more cities, its robotaxis initially will only be made available to a limited number of people with its ride-hailing app in Dallas, Houston, San Antonio and Orlando before the service will be available to all comers in those markets.
