A Houston-based company is kicking it with some fresh funding with plans to expand development of its marketplace platform.

Unique sneaker trading platform, Tradeblock, has raised $8.9 million in funding from investment partners Courtside VC, Trinity Ventures, and Concrete Rose Capital. Per the news release, the company expects additional funding of around $4.5 million to its seed round.

Tradeblock — founded in 2020 by self-proclaimed "sneakerheads" and childhood friends Mbiyimoh Ghogomu, Tony Malveaux, and Darren Smith — will use the fresh funding to expand and improve its digital marketplace for shoes.

"Tradeblock is revolutionizing the way forward for the new emergent asset class of footwear," says Tradeblock angel investor Jason Mayden, former Nike and Jordan footwear designer and president of Fear of God Athletics. "The founding team's understanding of the nuances of culture and tech gives them an unfair advantage in the industry and the team’s desire to lead with inclusion, representation, and authenticity also provides them with unique and meaningful organic engagement."

Over the past two years, Tradeblock has grown to have over a million shoes listed online. The team has also grown, and Tradeblock's workforce is over 80 percent people of color.

“Black and brown communities have always been the backbone of the sneaker industry and sneaker culture,” says Ghogomu, who also serves as CEO. “Showing those folks that they can be the owners and operators of this industry as opposed to just consumers is both a point of pride and a deeply rooted responsibility for everybody at Tradeblock.”

Authentication is a priority for the company, and the fresh funding will go toward further development of this type of technology within the platform.

"The market for fake sneakers is itself a billion-dollar market. If you're trying to acquire a shoe that's worth hundreds or even thousands of dollars, you need to be absolutely certain that what you're getting is the real thing," Ghogomu previously told InnovationMap.

Houston-based 'sneakerheads' kick off new app to revolutionize the biz

STEPPING UP

Mbiyimoh Ghogomu remembers the moment he fell in love with his first pair of sneakers in the eighth grade. Growing up, he says "frugality was a virtue" in his household. "I was not rocking heat on feet for most of my childhood," he explains. On a mission for new basketball shoes, he found a brand new pair of Adidas T-Mac IIs, and his entry into sneaker culture was sealed.

Like Ghogomu, his childhood friends Tony Malveaux and Darren Smith each had their own awakening into the sartorial fascination of sneakers. The self-proclaimed sneakerheads founded Tradeblock in 2020, a new sneaker trading platform that provides collectors with a secure way to collect and trade shoes. After a successful beta, the Houston-based startup has recently launched a new mobile app available for iOS and Android users.

Malveaux, co-founder and director of authentication, started growing his sneaker collection during his job at Footlocker and currently owns nearly 40 pairs.

"My first paycheck came the same day that the Foamposites dropped in the electrolime colorway and let's just say my check wasn't too much bigger than the retail price," says Malveaux.

The former retail employee was using the ESPN Trade Machine in 2009, a website that lets you play the role of a team manager by creating different trade scenarios for players, when the idea for Tradeblock came to him. Malveaux shared his idea with best friend Smith, co-founder and COO, and the two held it in their back pocket for a decade.

"An entrepreneur to his very core, D was slanging Pokemon and Yu-Gi-Oh cards all the way back in elementary school," says Ghogomu of Smith. "After spending a few years in the dark cubicles of corporate America following his college graduation, he realized that he would never be truly happy or fulfilled unless he was building his own thing," he says.

Smith eventually escaped those dark cubicles and approached Malveaux about making Tradeblock a reality. The two started an Instagram and began a cross-country trip, visiting every sneaker event they could to research the needs of the marketplace. To cover the cost of travel, they sold off the majority of the impressive sneaker collection they'd built over the years and sometimes slept in their car to avoid extra expenses.

That year, the two also brought in their high school friend Ghogomu as a co-founder and CEO.

Tradeblock started with the three founders playing the middleman in trades through Instagram direct messages, and it soon grew into a fully functional web platform.

Kicks as currency

Sneaker collecting is no small expense, due in part to the enormous resale market. According to GQ, the coveted 2020 Dior x Air Jordan 1 sneakers retailed at $2,000 but skyrocketed to $10,103 at resale value. Even moderately priced items like the $140 Nike SB Dunk High "Reverse Skunk," a 4/20-themed release with a limited 420 pairs available, have a resale price of $4,500.

High demand and exclusivity have created a barrier to access. Some opportunists have even purchased online bots to scour websites for sneaker releases so they can make bulk purchases and resell the rest at premium costs.

"Besides the fact that nobody had taken on trading, which was already a known behavior in the sneaker community, we saw the exorbitant prices that sneakers were starting to sell at in the resell market," says Ghogomu. "We realized that a ton of true blue sneakerheads, people who were in the game for the love of kicks more than anything, were basically getting priced out of every shoe they wanted," he explains.

By providing a platform for sneaker collectors to trade shoes in their collection, the founders "could provide another outlet for them to acquire the shoes they wanted without having to spend next month's rent check," says Ghogomu.

The app allows you to explore other user collections, follow collectors to keep track of their newly added shoes, and create your own closet featuring your collection. "I think the biggest social aspect of our app today is the fact that sneakerheads can actually curate a unique profile and persona for themselves on Tradeblock, and then they can explore other sneakerheads' collections," says Ghogomu.

When wanting to pursue a trade, Tradeblock allows you to manage your offers from an inbox, review trade status, and review your trade history. Users can also negotiate monetary payment if a trade isn't quite equal with shoes alone.

Once a trade takes place, authentication is a priority.

"The market for fake sneakers is itself a billion-dollar market. If you're trying to acquire a shoe that's worth hundreds or even thousands of dollars, you need to be absolutely certain that what you're getting is the real thing," says Ghogomu.

To ensure customers are getting authentic sneakers, Tradeblock has a "two-factor authentication" where every shoe goes through a physical and digital inspection.

More than a throwback

Sneaker collecting dates back to the late 1970s, coinciding with the surge in popularity of the National Basketball League and the hip hop movement of New York City.

The first-ever Air Jordans were created in 1984 and worn exclusively by former NBA star Michael Jordan, and released to the public in 1985. Just last year, Jordan's original pair sold for a record $560,000 in a Sotheby's auction, according to Reuters.

Music heavily influenced a profusion of sneakerheads. Run-DMC released the popular song "My Adidas" in 1986, which stayed on top of the Billboard music charts for 16 weeks. The trend carried into the aughts, with the rapper Nelly debuting his 2000 hit "Air Force Ones."

The shoe style has even succeeded in permeating internet culture, with a slew of memes and influencers arriving to meet the moment.

"Damn Daniel," a viral video from 2016, has solidified its place in the ever-evolving online vault of cultural moments. The video which shows then-high schooler Daniel Lara's shoe collection led him to become one of TIME's "30 Most Influential People on the Internet" that year.

Sneakerheads have since found a community using online communication platforms like Instagram, Discord, and Facebook.

"We also noticed that sneakerheads were spending a ton of time on social media platforms showing off their kicks, exploring other people's collections, and just generally looking to connect with people who shared their passion for shoes," explains Ghogomu. "We thought that if we could capture that social energy in a platform that also facilitated trading, we could create something truly revolutionary for the culture," he says.

The most popular sneaker reviewers on YouTube have grown communities of hundreds of thousands of followers, earning a living off their connoisseurship. "Shoe-tubers are an integral part of the sneaker culture today. In many ways, they're like the sherpas of the sneaker world," says Ghogomu.

The growing social authority of sneakerheads has also helped fuel Tradeblock's launch. The company has seen success in driving awareness by creating an online community and building relationships with influential YouTubers.

Existing online sellers from eBay to Poshmark have provided a way for users to sell and buy items, but the process is transactional. Understanding the passionate community of collectors, Ghogomu says they wanted to "build not just a product, but a company and brand that genuinely put the people first and harkened back to the days when being a sneakerhead was just as much about the community as it was about the kicks in your closet."

Growing a community

Tradeblock currently has more than 23,000 collectors in its database, a number that is steadily increasing by the day. "What has really blown me away is just how supportive people have been from [the] jump," says Ghogomu.

The app currently has thousands of shoes in its database, including rare releases like the Nike Dunk Lobster collection and the Art Basel Jordan 1.

"We've even got a few pairs of the original Jordan 1s in the Chicago colorway from 1985… but you'll have to come correct if you want to trade for those," jokes Ghogomu.

Through the roadblocks that come with building a startup, Tradeblock users have been loyal.

"I genuinely couldn't count the number of times we've heard people say things like, 'I want to see y'all win,' but we never get tired of it," he continues.

"When you're trying to build something unlike anything else that exists in the world, it's easy to let doubt creep in. Any entrepreneur who says they've never asked themselves the question, 'Is this really possible or are we insane?' is lying to you," says Ghogomu. "I think that as people of color, those internal barriers are even higher because we have so few examples to look to in terms of seeing people who look like us building massively successful businesses," he continues.

As the company grows, the co-founders hope to strengthen the bonds of the sneaker community — a common factor that has strengthened their own friendship.

"When most people think about sneaker culture, they think about the shoes. When we think about sneaker culture, we think about the people," says Ghogomu.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."

Rice University launches new venture fund for university-affiliated startups

startup support

Rice University has launched its new One Giant Leap Ventures Fund I, which will invest in the university’s spinouts and alumni-founded startups.

The early-stage institutional venture fund will function with a hybrid structure that allows for participation from traditional equity investors and philanthropic investors. According to the university, the fund will invest up to $500,000 per Rice-affiliated company.

To be considered eligible for funds, companies must use intellectual property licensed by the university or be led or founded by alumni.

One Giant Leap will draw on support and mentorship from Rice’s pool of 60,000 alumni and aims to create educational opportunities within the investment phases, work with graduate and undergraduate venture students, explore the scaling and commercialization of their ideas, and help investigate all the facets of venture capital.

“Rice alumni bring an extraordinary depth of experience as entrepreneurs, investors and industry leaders, and One Giant Leap creates new ways to put that expertise to work for the next generation of Rice innovators,” Stephen Bayer, vice president for development and alumni relations, said in a news release. “It strengthens the connection between our alumni and the university while giving them meaningful opportunities to mentor, advise and support Rice-affiliated companies as they grow.”

The fund held its first close in August and made its first investment into Rice brain health spinout Motif Neurotech. Led by Rice faculty member Jacob Robinson, Motif is working to commercialize a minimally invasive neurostimulator that targets treatment-resistant depression. In May, the FDA approved the company to move forward with its first clinical trial.

“Research produces breakthrough technologies and our academic environment forms outstanding entrepreneurs,” said Adrian Trömel, the fund’s managing director, a Rice alumnus and a startup founder who also serves as Rice’s interim chief innovation officer.

One Giant Leap joins the already long list of Rice-led programs that foster innovation, including the Liu Idea Labs for Innovation and Entrepreneurship’s Innovation Fellows and Summer Venture Studio, the Rice Alliance’s Business Plan Competition, the Ion District, Woodside Rice Decarbonization Accelerator, Rice Nexus, the Biotech Launchpad and RBL Ventures and its upcoming 200,000 square-foot research lab the Arc.

“With One Giant Leap, I am excited that we are creating a unique structure that brings together traditional investment and philanthropic participation to invest in and help catalyze our startups, engage the deep expertise within the Rice ecosystem and transform those strengths into real-world impact,” Trömel added in the release.
