Houston-based medical device company Saranas has tapped a veteran of the healthcare industry as its new CEO.

Mike MacKinnon most recently was president and partner at Madison Ventures +, a private equity firm based in Greenwood Village, Colorado. The firm invests in companies in healthcare, real estate, finance, and other sectors.

Before joining Madison Ventures +, MacKinnon was CEO of Zidan Medical, a startup focused on treatment of airway lesions in patients with early stage lung cancer. He served in that role from 2019 to 2023.

Earlier, he was CEO of ROX Medical, a medical device company specializing in minimally invasive vascular therapy for patients with uncontrolled high blood pressure. He held that role from 2018 to 2019. He previously worked at Philips North America, Volcano, AtheroMed, Hansen Medical, Access Closure, and FoxHollow Technologies.

In a news release, Dan Wolterman, chairman of Saranas’ board and former president and CEO of Memorial Hermann Health System, calls MacKinnon “an accomplished executive with an impressive record of bringing disruptive technology to market, guiding strategy, and driving significant growth.”

Now president and CEO of Nashua, New Hampshire-based medical device company Conformal Medical, James Reinstein was president and CEO of Saranas from 2020 to 2022. Prior to Reinstein, Zaffer Syed held that position from 2017 to 2020. He's still an adviser for the company and recently announced his role as entrepreneur in residence at the Texas Medical Center.

Saranas is working on commercializing its Early Bird Bleed Monitoring System, touted as the first and only system FDA-approved bleeding detection system for procedures involving blood vessels. It is designed to detect bleeds early, enabling physicians to reduce medical risks and potentially avoid costly medical problems.

“Bleeding remains a common issue during and after endovascular procedures and can result in life-threatening complications,” says MacKinnon.

Since being founded in 2013, Saranas has treated over 1,200 patients with its device and has received $29.2 million in funding, according to Crunchbase. This includes a $12.8 million Series B round that Saranas got in 2021 from Chicago-based Baird Capital and Austin-based S3 Ventures.

The Early Bird device was developed at Houston’s Texas Heart Institute. The FDA approved the device in 2019.

Dan Wolterman, who served as president and CEO of Memorial Hermann Health System for 15 years, has been named to the board of directors of Houston-based ZIBRIO. The health tech company, which was founded based on NASA technology, has developed a device that measures balance.

"We're delighted to have Dan on the team," says Katharine Forth, ZIBRIO CEO and co-founder, in a news release. "He understands ZIBRIO's vision to work across the full continuum of care, empowering older patients and clinicians with quantifiable fall prevention. His experience and enthusiasm will be invaluable in helping us to achieve it."

Falling is the top cause of trauma injury and trauma death across all age groups, according to ZIBRIO's release, and the current cost of falls in people over 65 is $50 billion – which is expected to double.

"ZIBRIO is coming to market at a time when population health and prevention are key for Healthcare systems to generate outcomes. They have a strong team and an elegant solution to a complex problem that will help millions," Wolterman says in the release.

The company just recently announced its expansion, including another new C-level exec and a new 75,000-square-foot site in St. Louis.

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.
