It was race day for avid marathon runner, Debbie Mercer. She and her race pack got up early on a brisk winter's day in Chicago, Illinois, piling on warm layers over their compression tights, to run the Chicago Marathon.

Miles into the race, Mercer and her friends made a pit stop at the portable bathrooms. The female runners stood in long lines, awaiting their turns to do their business behind closed doors, while their male friends resorted to quickly and discreetly ducking behind the porta-potties, or finding nearby trees. Precious time ticked by as the women watched their male counterparts continue the race.

"I remember thinking 'I wish there was some way that we could do that too,'" Mercer recalls.

The Houstonian created Zip Hers, an activewear brand that has a full-length zipper lining the bikini area of each pant, to accommodate on-the-go women. The Zip Hers concept and design was intended to level the playing field for women and men when it comes to competitive sports.

"If we're wasting time on a bathroom break and they're not, that holds us back…Maybe it's our little tiny contribution to women's equality. We just really want to help women be the best that they can be," Mercer says.

From full-length pants and tights, to 3-inch compression or loose shorts, Zip Hers has established an array of products suitable active women. However, it was a long and winding road to producing such innovative, high-quality products that could be competitive in such a vast industry of activewear, according to Mercer.

Zip Hers in the making

Mercer kicked off prototype production in 2016. She jumped around to various designers and manufacturers, turning away samples that didn't quite fit her vision for the product. Part of the challenge, Mercer describes, was finding a manufacturer who could manipulate stretch and non-stretch fabric in high-quality ways. Maintaining maximum comfort and a sleek design were challenges when the new variable of a zipper was thrown into the mix.

"It took us a while to get the zipper design perfect so that it would fit well and have a design that was comfortable," Mercer says. "We had to find the right manufacturer to find the skill to make these. We found one in Dallas and one in Houston."

Through trial and error, the Zip Hers design team produced a smooth design that coexists seamlessly with the delicate areas that sit around the zipper. They created a custom-made zipper pull, an invisible, thin disk embossed with the Zip Hers logo.

"Women can easily grab it when they're squatting, and don't have to struggle to find it… you can't even tell that a zipper is there. It's very sleek," Mercer says. "They're all handmade. We have to have special fabric for the panels and…have to have special machines to get the seams just right."

By September 2019, the Zip Hers prototype was finalized and officially launched via the company's online retail site.

Zip Hers products, the first of their kind, are sure to change the game for female marathon runners, hikers and any other outdoor activity fanatics, Mercer says. With so many athletic brands available on the internet, Mercer hopes that Zip Hers' innovative approach to active wear, and the unique opportunity they offer to women, will help set the brand apart.

"We really don't see any other products out there like ours…As far as apparel goes, we're the only one," Mercer says.

Since launching last year, Zip Hers has watched their clientele expand with predominantly long distance runners and adventure goers. With the 'athleisure' trend on the rise, they're also seeing more women buying leisurewear for yoga classes, or indoor casual use. Mercer says that she hopes Zip Hers will continue to expand to reach female fishers, hunters, climbers, and even first responders, so that women never have to take off their duty belts.

From various race-day experiences of waiting in long bathroom lines as precious time ticks by, to when nature calls during outdoor activities involving co-ed company, Mercer confronted women's realities by proposing an empowering solution for women.

"Ultimately, it gives women a choice. What's more empowering for women than the power to choose what's best for them?" Mercer says.

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.
