HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

pitch perfect

For the third year, the Greater Houston Partnership's Houston Energy Transition Institute hosted its startup pitch competition at CERAWeek by S&P Global. A dozen startups walked away with recognition — and three some with cash prizes.

HETI joined partners Rice Alliance for Technology and Entrepreneurship and TEX-E for the 2024 Energy Venture Day and Pitch Competition at CERAWeek on Wednesday, March 20. Forty-two companies, which have collectively raised over $265 million in investment funding already, pitched to judges. Nine startups won awards across three tracks.

TEX-E, a Texas nonprofit that supports student-founded upstarts, had five of its companies pitch and three winners walked away with monetary prizes. Teams that competed in the TEX-E Prize track, many of which come from Houston universities, include:

  • AirMax, University of Texas at Austin
  • BeadBlocker, University of Houston
  • Carvis Energy Solutions, Texas A&M University
  • Coflux Purification, Rice University
  • Solidec, Rice University

Solidec, which is working on a platform to produce chemicals from captured carbon, won first place and $25,000. The company also recently scored a $100,000 grant from Rice's One Small Step Grant program, as well as a voucher from the DOE. Coflux Purification, which has a technology that destroys PFAS in filtration, won second place and$15,000. The company also secured a One Small Step Grant to the tune of $80,000. AirMax, which focuses on optimizing sustainability for air conditioning equipment, won third place and $10,000.

Last year, Houston-based Helix Earth Technologies took home the top TEX-E price and $25,000 cash awards. The venture, founded by Rawand Rasheed and Brad Husick from Rice University, developed high-speed, high-efficiency filter systems derived from technology originating at NASA.

The rest of the companies that pitched competed for non-monetary awards. Here's what companies won:

  • Group A (CCUS, oilfield solutions, analytics and minerals):
    • First place: Ardent
    • Second place: Vaulted Deep
    • Third place: Mitico
  • Group B (batteries, renewables, water, and grid technology):

    Houston startups closed $1.75 billion in 2025 VC funding, says report

    by the numbers

    Going against national trends, Houston-area startups raised 7 percent less venture capital last year than they did in 2024, according to the new PitchBook-NVCA Venture Monitor report.

    The report shows local startups collected $1.75 billion in venture capital in 2025, down from $1.89 billion the previous year.

    Houston-based geothermal energy company Fervo Energy received a big chunk of the region’s VC funding last year. Altogether, the startup snagged $562 million in investments, as well as a $60 million extension of an existing loan and $45.6 million in debt financing. The bulk of the 2025 haul was a $462 million Series E round.

    In the fourth quarter of last year, Houston-area VC funding totaled $627.68 million. That was a 22 percent drop from $765.03 million during the same period in 2024. Still, the Q4 total was the biggest quarterly total in 2025.

    Across the country, startups picked up $339.4 trillion in VC funding last year, a 59 percent increase from $213.2 trillion in 2024, according to the report. Over the last 10 years, only the VC total in 2021 ($358.2 trillion) surpassed the total from 2025.

    Nationwide, startups in the artificial intelligence and machine learning sector accounted for the biggest share of VC funding (65.4 percent) in 2025, followed by software-as-a-service (SaaS), big data, manufacturing, life sciences and healthtech, according to the report.

    “Despite an overall lack of new fundraising and a liquidity market that did not shape up as hoped in 2025, deal activity has begun a phase of regrowth, with deal count estimates showing increases at each stage, and deal value, though concentrated in a small number of deals, falling just [8 percent] short of the 2021 figure,” the report reads.

    Sandbox VR brings new gaming center to Houston's tech-savvy population

    Get In The Game

    Sandbox VR, a futuristic, full-body virtual reality gaming experience, has announced it will enter the Houston market this month, opening its first local gaming center on January 23.

    "Houston's reputation as a hub for innovation and technology makes it a perfect fit for Sandbox VR," said Steve Zhao, CEO and founder of Sandbox VR, in a statement. "The city's diverse, tech-savvy population and strong entertainment culture create an ideal environment for our immersive VR experiences. LOL Entertainment continues to exceed our expectations as a partner, and we're excited to bring our cutting-edge virtual reality gaming to Texas's largest city."

    The new gaming center opens Friday, January 23 at 797 Sorella Court in CityCentre.

    One of the games that stands out is the Stranger Things: Catalyst game, based on the blockbuster Netflix television series. Groups of one to six players will be dropped into the sinister Hawkins Lab and the mysterious Upside Down to fight Demogorgons and other monsters. The game features Matthew Modine reprising his role as Dr. Martin "Papa" Brenner, who imbues players with psychic powers.

    Other games include the supernatural pirate title The Curse of Davy Jones and other Netflix tie-ins based on Zack Snyder's Rebel Moon and Squid Game. Sandbox VR offers fully-immersive group play activities that range from combat to puzzle solving for a variety of age groups.

    The opening of Sandbox VR is another part of the expansion of LOL Entertainment, who touts itself as one of the pre-eminent hosts of immersive and gaming experiences in the U.S. Sandbox VR will be their first entry into the Houston market, with another immersive group adventure game, Time Mission, set to open at the the Marq'E Entertainment District later this year.

    “Bringing Sandbox VR to CityCentre Houston is a big milestone for LOL Entertainment, for Sandbox VR, and for this market,” said Rob Cooper, CEO of LOL Entertainment. “Houston is a fast-growing, experience-driven city, and we’re excited to give locals and visitors a truly immersive, social gaming destination that you can’t replicate anywhere.”

    Presale tickets for the grand opening of Sandbox VR are available here. Standard pricing is $55-$65 per event, but Sandbox VR is running a special for 30 percent off with code OPEN30 for those who purchase before Thursday, January 22. Presale buyers are also entered into a drawing for free Sandbox VR for one year.
