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 nonprofit news outlet will shut down after only 2 years

In the News

Amid financial challenges, the nonprofit Houston Landing online news outlet plans to shut down by mid-May.

In an April 15 announcement posted on its website, Houston Landing says that although it launched in 2023 with more than $20 million in seed funding, the outlet failed to attract enough revenue to continue operating. The announcement followed a vote by the organization’s board of directors to close the nonprofit newsroom. All 43 employees will be laid off, the Columbia Journalism Reviewreports.

“We are proud of the Landing’s coverage of Greater Houston and continue to believe deeply in the need for more free, independent journalism in our region,” Ann B. Stern, board chair of Houston Landing as well as president and CEO of the Houston Endowment, says in the announcement. “This decision was difficult but necessary. Houston Landing’s reporting has made a meaningful impact in the community, but it struggled to find its long-term financial footing.”

According to the announcement, the Landing’s board is exploring a partnership with the Austin-based Texas Tribune, a pioneer in nonprofit journalism, to potentially establish a local news initiative in Houston. Later this year, the Texas Tribune plans to open a locally focused newsroom in Waco. A similar newsroom is in the works in Austin.

“We have great respect for Houston Landing’s work in delivering high-quality, nonpartisan journalism to its readers,” says Sonal Shah, CEO of the Texas Tribune. “We also understand the profound challenges facing local newsrooms today — journalism is a public service and needs a strong ecosystem to thrive. We look forward to exploring how we can learn from what the Landing started and create a sustainable model that serves the Houston community. We will take time to explore the right path forward to ensure sustainability.”

Houston Landing was launched after a two-year study led by the American Journalism Project found many Houstonians were disappointed about a lack of trustworthy, deeply reported local news. Financial backers of the Landing include the American Journalism Project, the Houston Endowment, Arnold Ventures, the Kinder Foundation, and the John S. and James L. Knight Foundation.

Despite the high-profile support, the site struggled to find an audience. CJR notes that the Landing had approximately 13,000 newsletter subscribers and only generated about $80,000 in subscription revenue. In the article, executive editor Sewell Chan identifies a number of other issues, including a lack of editorial focus and changes in leadership. “But in the end, the gap between board and staff, between management and labor, and between runway and revenue was just too large to bridge,” he writes.

“While it’s with a heavy heart that we announce the closure of our newsroom, I want to express my deepest gratitude to the dedicated journalists and staff members who poured their passion into our mission every single day,” Houston Landing CEO Peter Bhatia says.

“Houston Landing demonstrates how a commitment to truth and accountability can transform communities and improve lives,” he adds. “I’m thankful to those who believed in us, supported us, and stood with us as we connected with each other through stories that inspired positive change.”

Houston space tech company develops new engine features with NASA funding

testing 1, 2, 3

Outfitted with a new type of aerospace technology, a rocket engine developed by Houston startup Venus Aerospace for hypersonic flights will undergo testing this summer.

Supported by a $155,908 federal Small Business Innovation Research (SBIR) grant from NASA, Venus Aerospace came up with a new design for nozzles — engine parts that help manage power — for its compact rocket engine. Venus Aerospace says the newly configured nozzles have “exceeded expectations” and will be incorporated into Venus’ upcoming ground-based engine testing.

“We’ve already proven our engine outperforms traditional systems on both efficiency and size,” Venus Aerospace CEO Sassie Duggleby says. “The technology we developed with NASA’s support will now be part of our integrated engine platform — bringing us one step closer to proving that efficient, compact, and affordable hypersonic flight can be scaled.”

The engine at the heart of Venus’ flight platform is called a rotating detonation rocket engine (RDRE). Venus says it’s the first U.S. company to make a scalable, affordable, flight-ready RDRE.

Unlike conventional rocket engines, Venus’ RDRE operates through supersonic shockwaves, called detonations, that generate more power with less fuel.

“This is just the beginning of what can be achieved with Venus propulsion technology,” says Andrew Duggleby, chief technology officer at Venus, founded in 2020. “We’ve built a compact high-performance system that unlocks speed, range, and agility across aerospace, defense, and many other applications. And we’re confident in its readiness for flight.”

Last fall, the company unveiled a high-speed engine system that enables takeoff, acceleration, and hypersonic cruising — all powered by a single engine. While most high-speed systems require multiple engines to operate at different speeds, Venus’ innovation does away with the cost, weight and complexity of traditional propulsion technology.

Among other applications, the Venus system supports:

  • Spacecraft landers
  • Low-earth-orbit satellites
  • Vehicles that haul space cargo
  • Hypersonic drones and missiles

Nvidia announces plans to produce AI supercomputers at new Texas plants

Manufacturing News

Nvidia announced Monday that it will produce its artificial intelligence supercomputers in the United States for the first time.

The tech giant said it has commissioned more than 1 million square feet of manufacturing space to build and test its specialized Blackwell chips in Arizona and AI supercomputers in Texas — part of an investment the company said will produce up to half a trillion dollars of AI infrastructure in the next four years.

“The engines of the world’s AI infrastructure are being built in the United States for the first time,” Nvidia founder Jensen Huang said in a statement. “Adding American manufacturing helps us better meet the incredible and growing demand for AI chips and supercomputers, strengthens our supply chain and boosts our resiliency.”

Nvidia’s announcement comes as the Trump administration has said that tariff exemptions on electronics like smartphones and laptops are only a temporary reprieve until officials develop a new tariff approach specific to the semiconductor industry.

White House officials, including President Donald Trump himself, spent Sunday downplaying the significance of exemptions that lessen but won’t eliminate the effect of U.S. tariffs on imports of popular consumer devices and their key components.

“They’re exempt from the reciprocal tariffs but they’re included in the semiconductor tariffs, which are coming in probably a month or two,” U.S. Commerce Secretary Howard Lutnick told ABC’s “This Week” on Sunday.

Nvidia said in a post on its website that it has started Blackwell production at Taiwan Semiconductor Manufacturing Co. chip plants in Phoenix. The Santa Clara, California-based chip company is also building supercomputer manufacturing plants in Texas — with Foxconn in Houston and Wistron in Dallas.

Nvidia's AI super computers will serve as the engines for AI factories, “a new type of data center created for the sole purpose of processing artificial intelligence,” the company said, adding that manufacturing in the U.S. will create “hundreds of thousands of jobs and drive trillions of dollars in economic security over the coming decades."

Mass production at both plants is expected to ramp up in the next 12-15 months, Nvidia said. The company also plans on partnering with Taiwan-based company SPIL and Amkor for “packaging and testing operations” in Arizona.

In a statement Monday, the White House called Nvidia’s move “the Trump Effect in action.”

Trump “has made U.S.-based chips manufacturing a priority as part of his relentless pursuit of an American manufacturing renaissance, and it’s paying off — with trillions of dollars in new investments secured in the tech sector alone,” the White House said.

Earlier this year, Trump announced a joint venture investing up to $500 billion for infrastructure tied to artificial intelligence by a new partnership formed by OpenAI, Oracle and SoftBank. The new entity, Stargate, was tasked with building out data centers and the electricity generation needed for the further development of the fast-evolving AI in Texas, according to the White House.

The initial investment is expected to be $100 billion and could reach five times that sum.
