A blockchain technology company that was founded out of Rice University has closed its latest round of funding.

Founded in 2017, Topl is a blockchain-as-a-service company that's developing a purpose-built blockchain ecosystem to empower impact and sustainability within its userbase of businesses. The company's $15 million series A round was co-led by Houston-based Mercury, Republic Asia, and Malta-based Cryptology Asset Group.

“Topl’s blockchain was purpose built to power the next wave of supply chains and markets, that are more sustainable and inclusive,” says Chris Georgen, founder and managing director of Topl, in a news release. “Every decision we’ve made has been relentlessly focused on this problem and it’s exciting to see this approach yielding results with more than 30 different impact-forward use cases already live or approaching launch. Through this latest fundraise and with the strong network we’ve built, we’re looking to accelerate the growth of our ecosystem and setting a goal of at least 100 applications launched by next year.”

The company, which is now headquartered in Austin but still has a presence in Houston, has raised over $20 million in investment to date. Topl announced its $3 million seed round of funding — also led by Mercury — in 2020.

“Despite broader market dynamics across the Web3 sector, Topl’s strategic and early focus on users allowed the team to build an incredibly strong foundation that can weather cycles by providing an increasingly in-demand service to companies implementing various sustainable initiatives,” says Samantha Lewis, principal at Mercury, in the release. “We are excited to support Topl in this pivotal growth period.”

The round included two new international investors in Topl. Republic Asia is a newly launched arm of private investing platform Republic that is focused on fintech and web3 solutions. Houstonian Youngro Lee leads the division as executive vice president at Republic and head of Republic Asia and will join Topl's board to assist with international expansion.

“Sustainability and climate considerations are no longer mere luxuries, but an absolute necessity for companies to contribute to global finance and commerce,” Lee says in the release. “Topl will make it easier than ever for any organization around the world to harness the power of blockchain to track and monetize their positive environmental impact.”

Cryptology, with its European operations, also brings Topl key international presence.

"It's been an honor to see Topl progress from when it first entered Iconic Lab's accelerator program back in 2018 to where it is today," says Patrick Lowry, CEO of Cryptology, in the release. "Cryptology is hyper-focused on driving crypto adoption in an impact-focused, sustainable manner. We are proud to add Topl to our portfolio of companies and excitedly await Topl's network decentralization."

In addition to increasing its international impact, Topl will reportedly continue to build out its blockchain and technology. Per the release, Topl expects to launch a traceability platform for ethically and sustainably sourced products later this year.

Topl, which launched a grant program to fund Web3 startups and developers with inclusive and sustainable solutions, plans to announce its first 20 grant awards early next year. The grant recipients will also receive development, go-to-market, and fundraising support from Topl's team and network.

Houston startup rolls out blockchain-as-a-service model

ESG BAAS

A Houston blockchain startup has launched a new service that allows companies to enroll in the platform in just a few clicks.

Houston-based blockchain network developer Topl has announced the new platform, which is in its public beta stage. Startups, mid-level, and enterprising companies can register online. The new blockchain-as-a-service tool is purpose-built for Environmental, Social and Corporate Governance, or ESG.

The new BaaS solution allows for users to provide tangible proof that's free from data loss or manipulation.

"Adoption of blockchain technology in enterprises has been slowed because of problems with ease of use and infrastructure management," says Chris Georgen, Topl's co-founder and chief architect, in a news release. "Topl's Blockchain-as-a-Service removes these barriers to entry and provides a seamless means of upgrading current platforms with blockchain technology."

Topl's beta version of its blockchain as a service is available for free for startups and small companies, but it also has $50 and $500 a month pricing plans for larger operations.

The Topl team also recently announced it has published a new white paper called "Virtual Reality, Adapting Coffee Supply Chains To COVID-19." It focuses on how coffee supply chains are able to adapt digitally to the changes brought about by COVID-19. According to the release, the paper shows how blockchain technology allows every person and company of the global coffee supply chain can be included in the process.

Topl recently closed its $3 million seed round in December of last year. The round was led by Houston-based Mercury Fund with support from Houston-based GOOSE Capital, among others.

"We're grateful to have closed an oversubscribed venture round during a pandemic, especially given the unfortunate truth that many women-led startups are getting much less investment during this time," Kim Raath, CEO of Topl, said of the raise. "Bringing transparency to causes dedicated to environmental and social good has never been more important. We are building a modern blockchain for a world where purpose and profit go hand in hand."

Coronavirus has placed new focus on digitization and supply chain, says Houston blockchain startup leader

HOUSTON INNOVATORS PODCAST EPISODE 25

From a business perspective, Kim Raath, founder and CEO of Topl, sees the challenges and expected recession caused by COVID-19 as an opportunity — and a test.

"A bunch of companies — like Airbnb — were built in the 2008 recession," Raath says on this week's episode of the Houston Innovators Podcast. "I'm excited to see if we make it through here, I think we can survive anything."

Topl was founded by Rice University graduates — Raath, James Aman, and Chris Georgen — to track impact in various industries, such as carbon footprints in oil and gas or fair wages for farmers in agriculture, via a robust blockchain network. The company closed a $700,000 seed round last year and is looking toward another round of investment this year — yes, even amidst the current situation.

Raath just recently took over as CEO for the company following the completion of her Rice Ph.D in statistics and a Master's in economics, and it was a perfect time for the founders to sit down and realign their company. Aman will continue to focus on the tech, Georgen will focus on the customer, and Raath will steer the ship.

"It was definitely a cool experience for us as founders to go through together, but I'm glad that all three of us came out of this excited about what we're doing moving forward," says Raath.

And then, the coronavirus hit, which, to Raath, has proven to be an added obstacle and an exciting time to be in the track and trace world of blockchain.

"A lot of these COVID-19 trackers that everyone is watching, the data is being pulled into these trackers in the same way you could be tracking your chocolate, diamonds, anything," says Raath. "I'm excited to see the virtual and digital side of this — people are realizing you can use data to visualize things — and at the same time use that data for informed decision making."

She's observed that people are actually thinking of the effects on supply chain — in more than just the business sense.

"I don't think any of us thought this much about supply chain. Most of us just went to the grocery store, and we had all these options," Raath says.

Raath, like many startup founders, have had to make some tough calls and some huge cuts to her business, which has been scrappy and bootstrapped most of its existence anyways. In the episode, she offers her fellow startup leaders some advice about making these cuts as well as reminds them, as well as herself, that everyone is in the same boat right now — ask yourself what you can do to stand out and survive.

"Everyone is in the same place — including your competition right now," Raath says. "You don't have control of the uncertainty — but no one does. What do you have control over right now and how can you act on that control. That's what my focus has been."

Houston-based blockchain company continues growth with expansion in Southeast Asia

making moves

A Houston startup that's created a global industrial blockchain network has announced a new application and expansion into a new market.

For the first time, Data Gumbo Corp.'s GumboNet will be used in geothermal energy drilling thanks to the startup's new Indonesia-based client, Air Drilling Associates, a drilling and project management service provider.

"Expansion into Southeast Asia with ADA's deployment signals GumboNet's global applicability and benefit to industry — in this case, geothermal energy development," says Andrew Bruce, CEO and founder of Data Gumbo, in a news release. "We are excited that Data Gumbo is entering yet another sector of the energy market for improvements across its supply chain."

ADA will use GumboNet to automate invoice payments of its contracts, including ADA's work on on major geothermal exploration drilling campaign for international power company. This project is part of the country's plan to develop infrastructure to meet national electrical energy needs.

"In geothermal energy, supply chain parties are sluggish to invoice and execute payments, remote operations exist all over the world, and it takes dozens of counterparties to get a well site up and running," says Diederik Zwager, CEO of Air Drilling Associates, in the release. "By implementing GumboNet, we will gain greater transparency into our operations, and experience billing and invoicing execution at a monumentally faster rate."

Zwager will also become an adviser for Data Gumbo and is eager "to implement the network at ADA to pass along the benefits to customers, vendors and suppliers," he says in the release. The company has a presence in Southeast Asia, the Middle East, the Asia-Pacific region, and North and South America.

Since its inception in 2016, Data Gumbo has raised a total of $9.3 million — recently closing a $6 million series A led by Saudi Aramco's venture arm. While that recent pop of investment means expanding to new industries — the company announced its entrance into the construction industry — Bruce preciously commented that these funds would go toward taking Data Gumbo to new global markets.

"The whole thing for us is building this blockchain network of interconnected companies," Bruce says on a recent episode of the Houston Innovators Podcast. "The more companies that are a part of that network, the more value that network has."

Houston blockchain company plans for huge growth — from new offices to new industries

HOUSTON INNOVATORS PODCAST EPISODE 9

Andrew Bruce saw that the oil and gas industry had a data problem. If energy companies were ever going to be able to set up autonomous drilling, they needed to integrate data and challenge the commercial model.

On this week's episode of the Houston Innovators Podcast, Bruce, CEO of Data Gumbo Corp., shares how he created a solution to move the needle on streamlining data within industry.

"Data Gumbo was originally founded to solve that integration problem. Take data from different sources, standardize it, clean it up, and make sure only the people who have the authority to get access to the data, can get access to the data," Bruce says on the podcast. "That's why we're called Data Gumbo — take a bunch of data, put it in the pot, stir it up, and make it taste good."

Since its inception in 2016, Bruce has led the company to raise a total of $9.3 million — recently closing a $6 million series A led by Saudi Aramco's venture arm. While that recent pop of investment means expanding to new industries — the company announced its entrance into the construction industry — Bruce says the funds will also take Data Gumbo to new global markets, including the Middle East.

"The whole thing for us is building this blockchain network of interconnected companies," Bruce says. "The more companies that are a part of that network, the more value that network has."

Bruce discusses his planned growth, the origin story of Data Gumbo, and how the Houston innovation ecosystem has helped the company grow in the episode. Listen to it below and subscribe wherever you get your podcasts.

Houston oil and gas blockchain company expands into new sector

Building blockchain

With a new partnership, Houston-based Data Gumbo Corp. will move into a new sector within oil and gas, allowing the startup to tap into the Permian Basin.

Austin-based Antelope Water Management, which provides sustainable water solutions within the O&G industry, has partnered with Data Gumbo on its blockchain network, called GumboNet™, allowing the Houston startup to go beyond the drilling sector. The partnership means Data Gumbo will have life operations in both onshore and offshore drilling, including in the shale basins, according to a news release.

"As an integrated water management company in the Permian Basin providing tailored management services for water infrastructure, we look forward to incorporating Data Gumbo into each of our business units," says Dustin Brownlow, CEO of Antelope, in the release. "Data Gumbo is a game changer enabling us to provide customers, vendors, and regulators the best experience that smart contracts can offer."

According to the release, this partnership is the first use of a blockchain platform for water management services in U.S. shale sites in the industry.

"Data Gumbo was the first blockchain in offshore drilling and now we are the first in oil and gas water management. We anticipate continuing to break ground across the industry as companies realize the vast benefits we afford them such as security, certainty of data and, most of all, savings to the bottom line," says Andrew Bruce, CEO of Data Gumbo, in the release.

The technology allows for valuable cost-saving initiatives, including lower overhead expenditures, fewer outstanding payments between parties, and data certainty for business transactions.

Data Gumbo operates as a blockchain-as-a-service company, where clients across midstream, drilling and completions opt into the network service. The company was founded in 2016 and recently closed a $6 million Series A round.

Oxy's $1.3B Texas carbon capture facility on track to launch this year

gearing up

Houston-based Occidental Petroleum is gearing up to start removing CO2 from the atmosphere at its $1.3 billion direct air capture (DAC) project in the Midland-Odessa area.

Vicki Hollub, president and CEO of Occidental, said during the company’s recent second-quarter earnings call that the Stratos project — being developed by carbon capture and sequestration subsidiary 1PointFive — is on track to begin capturing CO2 later this year.

“We are immensely proud of the achievements to date and the exceptional record of safety performance as we advance towards commercial startup,” Hollub said of Stratos.

Carbon dioxide captured by Stratos will be stored underground or be used for enhanced oil recovery.

Oxy says Stratos is the world’s largest DAC facility. It’s designed to pull 500,000 metric tons of carbon dioxide from the air and either store it underground or use it for enhanced oil recovery. Enhanced oil recovery extracts oil from unproductive reservoirs.

Most of the carbon credits that’ll be generated by Stratos through 2030 have already been sold to organizations such as Airbus, AT&T, All Nippon Airways, Amazon, the Houston Astros, the Houston Texans, JPMorgan, Microsoft, Palo Alto Networks and TD Bank.

The infrastructure business of investment manager BlackRock has pumped $550 million into Stratos through a joint venture with 1PointFive.

As it gears up to kick off operations at Stratos, Occidental is also in talks with XRG, the energy investment arm of the United Arab Emirates-owned Abu Dhabi National Oil Co., to form a joint venture for the development of a DAC facility in South Texas. Occidental has been awarded up to $650 million from the U.S. Department of Energy to build the South Texas DAC hub.

The South Texas project, to be located on the storied King Ranch, will be close to industrial facilities and energy infrastructure along the Gulf Coast. Initially, the roughly 165-square-mile site is expected to capture 500,000 metric tons of carbon dioxide per year, with the potential to store up to 3 billion metric tons of CO2 per year.

“We believe that carbon capture and DAC, in particular, will be instrumental in shaping the future energy landscape,” Hollub said.

New app by Sports Illustrated grants access to 700 sports courts in Houston

Goal!

A new sports center booking app CatchCorner, powered by Sports Illustrated, enables sports enthusiasts in Houston to seamlessly secure a spot for a quick game without membership fees.

It soft-launched in Houston this spring and, according to co-founder and chief operating officer Maya Azouri, has been a huge success.

"The Houston expansion has been jaw-dropping," she said. "Up until now, CatchCorner’s launch in New York City had been our most successful market, but Houston has launched on par with it."

Within a 30-day period this summer, over 30,000 users join the app, Azouri noted, adding that the app would include 700 unique recreational spaces users can choose from in the city.

"There’s a real sports culture here, with athletes of all levels from casual weekend players to competitive amateurs and even pros. The diversity of the sports community, combined with the number of high-quality facilities across the city, makes it a perfect fit for CatchCorner," she said.

CatchCorner in Houston offers bookings for basketball, volleyball, soccer, pickleball, padel, baseball, badminton, and tennis, with plans to include golf simulators and ice rink sports soon. The Zone Sports, Toros HTX, PAC Gym, and Houston Pickleball Center are among the most popular venues.

Using the app is a snap. Once you pick your sport, venues with available slots are listed including distance from you with the booking schedules in the results so there are no surprises. The slots can go fast, so occasional error messages pop up when trying to book, but it's otherwise a three-click process. CatchCorner also helpfully includes a picture of the facilities while booking.

CatchCorner announced Google integration in June that lets users book through the app directly from searches when they look up specific venues. This is slightly less intuitive to use than the app, but it does ultimately work in both mobile and desktops versions. Either way, it greatly streamlines the booking process for people who just want to schedule a quick pickup game somewhere.

"It’s especially useful for casual players or people who want to organize something on short notice," said Azouri. "Whether it’s a weekend basketball run, a weekday futsal match, or a spontaneous pickleball game with friends, CatchCorner makes it easy to coordinate without the usual logistical headaches.

"Some feedback here has been that we’re like 'Expedia for sports.' It’s because booking a flight online is that easy, booking your next game or workout should be just as simple."

10 Houston billionaires make Forbes' list of richest Americans in 2025

The Rich List

America's wealthiest billionaires are $1.2 trillion richer in 2025, bringing their collective worth to a staggering $6.6 trillion. And Houston's own Richard Kinder has become the richest billionaire in the city, according to the new Forbes 400.

The Kinder Morgan chairman is the 11th richest Texas resident and ranks as the 108th richest American. Kinder also dethroned Tilman Fertitta to claim the title as the wealthiest Houstonian.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies.

Kinder's wealth

The publication estimates Kinder's net worth at $10.6 billion, up from $8.1 billion last year. He also appears among Forbes' separate list of the richest billionaires in the world.

"It’s been a year unlike any we’ve seen in the four decades we’ve tracked America’s billionaire class,” said Forbes senior editor Chase Peterson-Withorn in a press release. "The super-rich at the very top are richer than ever — and between the White House and the booming stock market, they’re as powerful as they’ve ever been."

Kinder, 80, co-founded oil and gas pipeline firm Kinder Morgan in 1997, which is now known as one of the largest American energy infrastructure companies. He stepped down as CEO in 2015, though he still chairs the board of directors.

Kinder and his wife, Nancy, also founded Houston-based nonprofit the Kinder Foundation in 1997. The organization provides "major gifts to public causes with the intention of helping people realize healthy and rewarding lives," according to its website.

In May 2025, the Kinders pledged $150 million to Texas Children's Hospital and MD Anderson to create the Kinder Children's Cancer Center.

"Our philanthropic efforts center on supporting transformational projects in Houston, and this initiative exemplifies that mission in every way," said Kinder in a press release. "We were deeply impressed by the extraordinary leadership and unwavering commitment of both UT MD Anderson and Texas Children’s to pursue a bold, collaborative model of care. It is a rare and powerful moment when two leading organizations come together to create something entirely new – something capable of reshaping the future of pediatric cancer care."

The richest Houstonians

In all, 43 Texas billionaires made it on the 2025 Forbes 400 list, and 10 are based in the Houston metro.

Hospitality honcho Fertitta, 68, is the second-richest billionaire in Houston, and his net worth has jumped from $10.1 billion last year to $11 billion in 2025. He owns the Golden Nugget Casinos, the Houston Rockets, Texas-based restaurant and entertainment company Landry's, and also serves as the U.S. Ambassador to Italy.

"Serving as President Trump's ambassador to Italy 'is a real job,' says Fertitta, who personally oversaw the renovation of Villa Taverna, the ambassador's residence in Rome," Forbes wrote in his profile.

Fertitta most recently put his ritzy 250-foot-long superyacht on the market for about $192 million, with Forbes saying he "has a bigger one on order."

Here's how the rest of Houston's billionaires fared on this year's list:

Oil tycoon Jeffery Hildebrand ties for No. 123 nationally with an estimated net worth of $10 billion. Last year: $7.6 billion.
Toyota mega-dealer Dan Friedkin ranks 128th nationally with an estimated net worth of $9.7 billion. Last year: $7.6 billion.
Houston pipeline heir Randa Duncan Williams ranks 130th with an estimated net worth of $9.5 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 135th nationally. Each has an estimated net worth of $9.4 billion. Scott Duncan ranks No. 141 with a $9.2 billion estimated net worth.
Houston Texans owner Janice McNair ranks 201st nationally with an estimated net worth of $7.3 billion. Last year: $6.2 billion.
Energy exploration chief exec George Bishop of The Woodlands ranks No. 325 with an estimated net worth of $4.7 billion. Last year: $5 billion.

Richest billionaires elsewhere in Texas

The richest person in America in 2025 is none other than Austin-based Elon Musk. Musk, 54, saw his net worth skyrocket to $428 billion this year, or $184 billion more than his 2024 net worth. He claimed the No. 1 spot for the fourth time.

Walmart heiress Alice Walton of Fort Worth was dubbed the wealthiest woman in America for 2025. Walton, 75, simultaneously holds the title as the richest woman in the world. Forbes estimates Walton's net worth at $106 billion (up from $89.2 billion last year) and proclaims her as the first female centibillionaire (a person with a 12-digit fortune) in America. Now that's wealth.

"Tariffs. Inflation. Slowing employment. None of it has hit the fortunes of America’s billionaires," Forbes said. "A decade ago, when it took $1.7 billion to make The Forbes 400, a net worth of $3.8 billion was comfortably within the top half of the ranking — now that lofty sum is the minimum required."
