Anyone who's witnessed even just a minute of basketball knows how important accuracy is in sinking shots on the court. One Houston startup has developed a device to help practice make perfect in a game.

GRIND’s portable basketball shooting machine, the first of its kind, was created by founder and CEO Thomas Fields, former basketball phenom at Houston’s Reagan High School (now Heights High School).

“I remember being on varsity as a freshman and shooting thousands of shots every day trying to be the best,” says Fields. “My school bought a shooting machine, but they never let me use it. It was a game-changing piece of equipment, and I didn’t even have access because the gyms were always closed or closing.

“And another major problem was getting your rebounds, so we set out to make a portable basketball rebounding machine, so you could take it anywhere like home, the park, or the gym. It was also important to make it affordable, too.”

At just 110 pounds, the GRIND shooting machine is 54 percent lighter than other home shooting machines, has a 12-foot net, and needs just 90 seconds to set up or take down.

“Our portable shooting machine has been on the market for about three, four years now,” says Fields. “So now it's time to kind of accelerate the growth, and that’s pretty exciting. We really have our sights on NBA Africa for a partnership there. Another one is Adidas; we are collaborating with them right now and they're also one of the sponsors of Black Hat Mission. And hopefully, we would like to land some NBA guys to invest and really get behind our sportstech company, but also make a significant impact in the community by getting kids into tech through sports.”

To that end, GRIND recently won second place in a competition from Black Ambition, an organization founded by Pharrell Williams. With the tagline, “Uninterrupted ambition. Unmatched impact,” the Black Ambition Prize celebrates underrepresented founders globally.

“When I initially heard of Black Ambition, I just kind of heard that Pharrell had started a venture fund aimed at uplifting black and brown entrepreneurs,” says Fields. “And when I read more about it, I realized that their mission perfectly aligned with GRIND. Our goal is to try to get kids into tech and STEM, but use sports as the conduit and the bridge to get them there.

“We applied for the million-dollar cash prize for first place, but took second place, which is a $250,000 investment in the company. So now that Pharrell and Black Ambition are behind us, we are going out and raising some more capital to hit that hyper stage that we're going into. We are launching our software next year and our hardware has really been growing.”

Fields pitched GRIND on Shark Tank in May of 2021, where he was offered a joint deal for $250,000 for 25 percent of the company from both Mark Cuban and Barbara Corcoran. While Fields agreed on the show, the finalized terms of the deal were not disclosed.

As a startup, GRIND, a consumer brand developing the world’s first smart ecosystem of sports equipment products, represents the continued uptick with sportstech innovation in Houston.

“We want to revolutionize the world of sports equipment by leveraging cutting edge technology by developing sports equipment that can seamlessly connect to software, enhancing athletic performance, and pushing athletes to achieve their peak potential,” Fields says.

As GRIND continues to push forward and expand its footprint, it’s also looking to expand its customer base.

“I think the target users are middle school and high school athletes,” says Fields. “These are the kids that are striving to be great athletes and striving to get into college. We also have colleges that have our product, as well. But mostly, the customer is the parents of those athletes. That's really who we're trying to get excited.

“And then, of course, there are the coaches and trainers. They own gyms; they own organizations and need equipment for their schools and universities. That's another target customer of ours for sure.”

Ultimately, GRIND will continue to build on Fields’ initial inspiration to design products and technologies with the athletes — especially hoopers — in mind.

“Our goal in the next few years is to really amp up the scholarships that we facilitate to funnel kids into STEM tech careers and pathways,” says Fields. “GRIND Day, which is a proclamation the City of Houston gave us for August 12 each year, is a day where we bring sports, tech, and culture all under one umbrella. Kids see us using 3D printers and lasers to cut the products that we make in our warehouse, which is in an underserved community, which hopefully makes them think it’s cool and want to get into 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.
