Here are the most promising energy tech startups in the market today. Natalie Harms/InnovationMap

This week, 39 energy startup companies from all over the world pitched in Houston — and nine were recognized as being the most promising of the batch.

The Rice Alliance for Technology and Entrepreneurship returned its Offshore Technology Conference pitch event to its in-person capacity and host the annual event at the Ion Houston for the first time. The event featured three-minute pitches from the companies, and a select group of corporate and venture investors decided on the top nine to honor.

"We asked investors and corporates to look at the companies here today and help us determine the companies most promising — based on those that have an innovative technology that is solving a large problem, has customers willing to pay for it, and has the right team to build and grow their company," Brad Burke, managing director of the Rice Alliance says to the crowd at the event on May 3.

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.

Baylor College of Medicine names Minnesota med school dean as new president, CEO ​

new leader

Dr. Jakub Tolar, dean of the University of Minnesota Medical School, is taking over as president, CEO and executive dean of Houston’s Baylor College of Medicine on July 1.

Tolar—who’s also vice president for clinical affairs at the University of Minnesota and a university professor—will succeed Dr. Paul Klotman as head of BCM. Klotman is retiring June 30 after leading Texas’ top-ranked medical school since 2010.

In tandem with medical facilities such as Baylor St. Luke’s Medical Center and Texas Children’s Hospital, Baylor trains nearly half of the doctors who work at Texas Medical Center. In addition, Baylor is home to the Dan L Duncan Comprehensive Cancer Center and the Texas Heart Institute.

The hunt for a new leader at Baylor yielded 179 candidates. The medical school’s search firm interviewed 44 candidates, and the pool was narrowed to 10 contenders who were interviewed by the Board of Trustees’ search committee. The full board then interviewed the four finalists, including Tolar.

Greg Brenneman, chair of Baylor’s board and the search committee, says Tolar is “highly accomplished” in the core elements of the medical school’s mission: research, patient care, education and community service.

“Baylor is phenomenal. Baylor is a superpower in academic medicine,” Tolar, a native of the Czech Republic, says in a YouTube video filmed at the medical school. “And everything comes together here because science saves lives. That is the superpower.”

Tolar’s medical specialties include pediatric blood and bone marrow transplants. His research, which he’ll continue at Baylor, focuses on developing cellular therapies for rare genetic disorders. In the research arena, he’s known for his care of patients with recessive dystrophic epidermolysis bullosa, a severe genetic skin disorder.

In a news release, Tolar praises Baylor’s “achievements and foundation,” as well as the school’s potential to advance medicine and health care in “new and impactful ways.”

The Baylor College of Medicine employs more than 9,300 full-time faculty and staff. For the 2025-26 academic year, nearly 1,800 students are enrolled in the School of Medicine, Graduate School of Biomedical Sciences and School of Health Professions. Its M.D. program operates campuses in Houston and Temple.

In the fiscal year that ended June 30, 2024, Baylor recorded $2.72 billion in operating revenue and $2.76 billion in operating expenses.

The college was founded in 1900 in Dallas and relocated to Houston in 1943. It was affiliated with Baylor University in Waco from 1903 to 1969.
