With fresh funding, a Houston-based health tech platform that's less than a year old has grown its United States footprint.

CardioOne, which has created a cardiology care delivery enablement platform that serves independent cardiologists, has closed an $8 million seed round of funding and secured three new partnerships. Axios and Crunchbase report that the round has closed, and CardioOne confirms the funding and new partnerships in a press release.

The company has three new partnerships with independent cardiology clinics in New Jersey, Florida, and Pennsylvania, Cardiac Associates of New Jersey, Twin Hearts LLC, and Corrieius Cardiology. The trio joins existing partner practices in Texas and Maryland.

In addition to joining forces with these practices, CardioOne has entered into a partnership with MedAxiom, which is described as being "the cardiovascular community’s premier source for organizational performance solutions," in the release.

“CardioOne is optimizing cardiology practice management and providing new options for independent cardiologists,” Joe Sasson, MedAxiom’s executive vice president of ventures and chief commercial officer, says in the news release. “With CardioOne, independent cardiology practices can access the scale and leverage typically reserved for large hospital groups and are empowered to grow through additional service lines, strong network relationships, and payor contracts, including value-based care arrangements.”

Dr. Jasen Gunderson, who's based in Denver, is the CEO and co-founder of CardioOne, which was founded last year. He explains the challenges of independent cardiologists, which includes inefficient revenue cycle tools, incomplete vendor management systems, and other tech-based and administrative obstacles — most of which CardioOne addresses.

“Inadequate and fragmented technology is at the root of many of the problems that independent cardiologists are facing today,” Gunderson says in the release. “CardioOne’s solution removes the heavy administrative burdens, empowering cardiologists to focus on their expertise and true passion – the practice of medicine without feeling forced into acquisition.”

CardioOne's mission is to continue to help cardiology practices maintain their independence while keeping up with demand, patient care, and business growth.

"Our independence and clinical autonomy has allowed our practice to provide more personalized care to our patients, but in a consolidating market... the resources and technology investments required to run a practice group today make staying independent more difficult than ever before,” Dr. John H. Lee of Cardiac Associates of North Jersey, says in the release. “CardioOne is a true collaborator, serving as an extension of our operations and allowing us to focus on doing what we love — caring for patients.”

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.
