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.”

Even amid a pandemic, a Houston startup accelerator focused on local, early-stage companies has announced its new cohort and is operating its program virtually.

International accelerator gener8tor announced last fall that its early-stage program, gBETA, was coming to Houston following a $1.25 million grant approved by Houston's Downtown Redevelopment Authority. gBETA, which named its local leader and opened applications in January, now has revealed the five companies that will participate in the free, no-equity accelerator.

"This cohort was selected from among a highly competitive pool of applicants, and I'm so pleased with how they have adapted to the impacts of COVID-19 on the program and their businesses," says Eleonore Cluzel, director of gBETA Houston, in a news release.

The program kicked off April 30 and the five companies will graduate at a virtual pitch event June 18. While completely virtual this time around, the plan was to co-locate the program with MassChallenge Texas in Amegy Bank's Downtown Launchpad. The program is expecting to continue with its second cohort later this year.

"We are committed to establishing Downtown as a nexus for innovation and a leader in urban entrepreneurship and we applaud the talent of the first cohort, especially under these unprecedented circumstances," says Jonathan Brinsden, Central Houston's board chair, in a news release. "We look forward to them joining MassChallenge in the Downtown Launchpad at Amegy at Main this coming summer."

The spring 2020 gBETA cohort includes:

  • Best Bites Houston — a food tourism company that conducts exclusive food tours both in-person and virtually, exploring culture within cuisine.
  • Blown Assignments LLC — a web tool geared at improving communication between student athletes and their coaches.
  • GRIND — a sportstech company that merges sports and design to create products and services for athletic training.
  • Learn2Code.Live — a provider of computer science programming company that serves both students and teachers virtually.
  • Zent LLC — the creator of an innovative toothbrush called the Zent Flex that improves oral disease prevention and — no matter how hard a user brushes — physically limits brushing pressure to the optimal pressure.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.
