Blockchain has really started to come into its own as more and more companies are applying the technology across industries — from oil and gas analytics and fundraising to even social media marketing.

Five Houston companies have made their mark on these different industries by incorporating this burgeoning technology.

As the blockchain-as-a-service company's name suggests, Houston-based Data Gumbo is all about the data.

"The whole idea is to build out the blockchain network, and provide a network that they can subscribe to and start doing business on that network," Andrew Bruce, CEO of Data Gumbo, says. "It's a service, so there's a subscription fee. It gives them access to the savings they already have available within their organizations."

The company, which focuses on providing midstream and upstream oil and gas companies with timely decision-making information, was launched in 2016 and faced a big learning curve in the industry.

"We got a lot of questions and concerns about what blockchain is, why they need it, and whether or not they can trust it," Bruce says. "We were introducing a completely new concept to a conservative industry."

The industry is coming around as Data Gumbo grows its network and proves results.

Social Chains

When it comes to social media marketing, Houston-based Social Chains is putting the power back into the hands of users. Big social media companies, like Facebook, sell data about you to marketers and advertisers, and there's nothing you can do about it. Social Chains is a new platform where users own their own data and receive a cut of the payment.

"On our platform, the user is a stakeholder. Our platform distributes 50 percent of the profits to the users," Srini Katta, founder and CEO of the company, says.

Social Chains already has 5,000 users and, Katta says, that's with little to no marketing efforts. Currently, he's been working out a few kinks before launching into marketing for the platform, though he expects to do that beginning next month. Most of Social Chain's current users are high school to college students, so that will be the primary demographic for the marketing strategy.

Topl

Blockchain, when applied to consumer products, can be used to complete the full picture of that product. A chocolate bar, for instance, can be traced from cacao farm to grocery store. Not only does the connected information keep each party accountable when it comes to prices, it tells a story.

"We are a generation that wants a story," says Kim Raath, CFO of Topl. "We want an origin, and don't want to be fooled. And, because you might be able to reduce the cost by having this transparency, you might be able to bring down the cost on both sides."

Topl, a Houston-based startup that was created by a few Rice University graduate and doctorate students, uses blockchain to connect the dots. One of the ways Topl's technology is being used is to track money. If an investor gives to a fund, and the fund gives to a startup, there's nothing to connect that first investor to the startup's success or to measure its impact. This is a tool used by investors or donors alike. For instance, if you were to create a scholarship, you can use Topl to track what student received that money and if they are meeting the required metrics for success.

Topl's 2019 focus is on growing its network and what it's able to provide its clients, like an app factory for companies trying to track specific things.

The stock market has been using tech for years — why shouldn't the private sector have the same convenience? Getty Images

To Rashad Kurbanov, the private investment world was extremely backwards. While the stock market had been digitizing investment for years, private funds had a drawn out process of emails and meetings before moves were made. He thought introducing technology into the process could help simplify the investing for both sides of the equation.

"What we do, and where technology helps us, is we can take the entire process of receiving interest from investors, signing the transactions, issuing the subscription agreements, and processing the payments and put that all online," says Kurbanov, CEO and co-founder of Houston-based iownit.us.

The company is still seeking regulatory approval, but once that happens, the technology and platform will be ready to launch. The platform is a digital site that connects investors to companies seeking money. The investors can review the companies and contribute all online while being encrypted and protected by blockchain.

Houston Blockchain Alliance

The Houston Blockchain Alliance is a newly formed networking group for anyone working within or interested in the blockchain industry. Mahesh Sashital, co-founder of Smarterum, a blockchain news site, founded the organization late last year after realizing Houston was in need of an informative networking group.

"I thought that I'd start the Houston Blockchain Alliance so that someone like me, who's already in the industry, can find other people working in the industry," he says. "And for other people interested in blockchain can learn more and get up to speed with the technology."

The alliance aims to host regular events — its launch event is Feb. 20 — and educate people on blockchain. Click here to read Sashital's guest column about common blockchain misunderstandings.

3 Houston tech innovators to know this week

Who's who

Often, technology and innovation are mistaken for each other. While not mutually exclusive, both tech and innovation work well together in Houston across all industries — from oil and gas to real estate and social media. These three founders engaged technology for their individual startups.

As a social media user, your data is already out there and being used for marketing purposes. But, rather than the Facebooks or Googles of the world making a profit, Srini Katta wanted to create a platform where users made a profit off their own data.

"On our platform, the user is a stakeholder. Our platform distributes 50 percent of the profits to the users," he says.

Social Chains already has 5,000 users and, Katta says, that's with little to no marketing efforts, which Katta is about to launch.

Martin Kay, founder and CEO of Entera Technology

Martin Kay, who splits his time between Houston and the Bay Area for his startup Entera Technologies, knew there had to be a better way for people searching for a home to buy. He drew a comparison between homebuyers and Netflix viewers to create Entera's software.

"We're a little bit like Netflix," he says. "They go out and get content from everyone, and they begin to watch your behavior. So, Netflix has 2,000 profiles and you probably fit five or six of those. We have almost 100 profiles and what we do is say, we're going to understand what you want, watch your behavior and instead of giving you 40,000 properties on a big map, we actually match you based on your preferences, to the five or six houses that are best for you."

Houston-based Entera has grown as the platform loads more and more data for its users to engage with.

Luther Birdzell, CEO and founder of OAG Analytics

Luther Birdzell always knew he wanted to run his own company, but the software and analytics professional worked in various industries before realizing that oil and gas had a huge opportunity for savings using analytics. He founded OAG Analytics in 2013 to help provide a solution for these companies.

"When I founded OAG Analytics, our mission then — and still is today — was to build a platform for the upstream oil and gas industry that enables them to manage their data, introduces world-class machine learning in minutes without having to write a single line of code, and allow them to run simulations on the resulting analysis," Birdzell says.

The company has grown to 25 employees and tripled its revenue last year. The team is forecasting another year of high grow for 2019.

Houston startup aims to flip the script on social media marketing

anti social media

Social media companies are using user data for their own financial gain, but what if users had a cut in the profits? That's the business model for Houston-based Social Chains.

"Social Chains is a social media platform of real people, real privacy, and real rewards," says Srini Katta, founder and CEO of the company. "We're fixing three problems in the social media industry."

The first problem is that user data has market value, but only the Facebook, Google, and other platforms are reaping the rewards, not the user, who's the backbone of the platform. User privacy and a growing number of fake accounts are the other issues Social Chains addresses. Katta says he realized that most importantly, users should own their data

"On our platform, the user is a stakeholder. Our platform distributes 50 percent of the profits to the users," he says.

User privacy is protected and encrypted on this new platform, and users must register with a government-issued identification. Social Chains prevents fake accounts by using facial recognition.

The biggest differentiating factor of this platform is that users make real money, but it's kept track by the site's token system, which uses blockchain technology, and users receive some of the so-called "S tokens" just for signing up. And, businesses only pay for the ads that users engage with. For instance, for a marketing email, businesses will only pay for the emails that were actually opened. It's a win-win situation, as the user receives a kickback whenever they open a marketing email or engage with ads.

Social Chains already has 5,000 users and, Katta says, that's with little to no marketing efforts. Currently, he's been working out a few kinks before launching into marketing for the platform, though he expects to do that beginning next month. Most of Social Chain's current users are high school to college students, so that will be the primary demographic for the marketing strategy.

Katta says he first encountered some of the challenges using social media marketing at one of his former startups when attempting to use Facebook ads to grow the company. He says he saw increased engagement, but not as significant of an increase in sign ups on his company page.

"We looked back to see who are the people clicking on the ads," he says. "We looked at their profiles, and they were not from the United States, even though we had given geographic preferences."

He found out that third party ad management platforms were working with Facebook and click farms all around the world to increase engagement results. Katta starting thinking of a solution for this marketing problem.

"Then, in 2016, with the rise of 'fake news,' we realized this was a bigger problem," he says.

In addition to user growth, Katta hopes to grow his investors, and the company is seeking funds for its seed round in 2019.

"To be honest, we need $100 million to build this out, so we're trying to raise money," Katta says. "Personally, I've put in $3.5 million before I took any money from investors. I have a lot of skin in the game."

Currently, Social Chains has three team members, with a fourth joining soon. Diane Yoo, who is a founding member and director of the Rice Angel Network, leads growth and investor relations for the company. One obstacle for the team has been being spread out from Houston to The Woodlands and even Austin.

"I've lived in New York and San Francisco. I moved to Houston because I wanted a quiet place to raise my family," Katta says. "The biggest challenge for Houston, compared to other cities, is other cities are so dense. Houston is so sprawling. It's really hard to network, and meet potential employees."

One of the crucial connectors for Katta has been Station Houston. The team plans on meeting to work together two days a week at Station. In addition to being a great workspace, the area acts as a good hub for potential partnerships for Social Chains. Startups need marketing, of course.

It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
