Data Gumbo, a Houston-based tech startup, has picked up $4 million in a series C round from the venture capital arms of foreign energy companies Saudi Aramco and Equinor.

The funding for Data Gumbo came from Saudi Aramco Energy Ventures, the VC subsidiary of government-owned oil and natural gas giant Saudi Aramco, and Equinor Technology Ventures, the VC subsidiary of Norwegian energy operator Equinor. The U.S. headquarters for both Saudi Aramco and Equinor are in Houston.

Data Gumbo said in January that it had signed up Equinor as a customer.

Only last year, Data Gumbo announced it had raised a $7.7 million series B round with participation by Saudi Aramco, Equinor Technology Ventures, and VC and private equity firm L37, which has an office in Houston. The startup has hauled in $26.7 million in funding since its founding in 2016, according to Crunchbase.

Data Gumbo provides a contract platform, GumboNet, that is powered by blockchain technology. The platform serves more than 180 corporate customers in the oil and gas sector. The startup says the funding will enable it to expand its contract automation offering beyond the energy industry.

“While we started in energy, we already have value for bulk commodity haulage, trucking and shipping, with plans to parlay our momentum into other global industries,” says Andrew Bruce, founder and former CEO of Data Gumbo. “Wherever two or more organizations share a contractual relationship that can be verified with a digital source of data, opportunities abound to realize efficiencies and cost savings utilizing our blockchain network.”

Frank Andrasco, senior investment director at Saudi Aramco Energy Ventures, says Data Gumbo’s platform “has broad industrial applicability.”

The announcement of the $4 million funding round comes on the heels of William Fox being named CEO of Data Gumbo in July. Fox had been the startup’s chief product officer.

“The partnership with Equinor and Saudi Aramco, and their associated supply chains and partnerships, will continue the momentum for the Data Gumbo’s smart contract network,” Fox says.

Earlier this year, Data Gumbo announced the opening of an office in Saudi Arabia. Data Gumbo’s headquarters is at The Cannon’s coworking space in the Energy Corridor. It also maintains offices in Norway and the United Kingdom.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from corporate venture capital to digital health — recently making headlines in Houston innovation.

When it comes to venture capital, the corporate model can be considered a little less risky, Jim Sledzik, North American managing director of Saudi Aramco Energy Ventures, says on last week's episode of the Houston Innovators Podcast. Over the past decade, Saudi Aramco Energy Ventures has invested $320 million into 33 portfolio companies in the United States. Sledzik, who's worked in various energy services roles around the world before entering in to investment, explains that the corporate venture model is ideal for scaling big technology — and fast.

“When you’re using the venture model in a corporate setting, you have the company and the balance sheet behind you, which brings different benefits to companies you’re investing in,” he says. “These entrepreneurs who are looking to figure out how to deploy technology at scale becomes the real interesting item. All entrepreneurs want to grow — and they want to grow fast."

Scaling fast is risky, but big corporates — like Aramco — can help address the risks by providing a foothold in the market, a place to roll out the technology, and more. Click here to stream the episode and read more.

Throughout her career, Arti Bhosale has seen the inefficiency and the ineffectiveness of selecting patients for clinical trials.

“Across the globe, more than 30 percent of clinical trials shut down as a result of not enrolling enough patients,” says Bhosale. “The remaining 80 percent never end up reaching their target enrollment and are shut down by the FDA.”

So, in 2020, Bhosale and her team developed Sieve Health, an AI cloud-based SaaS platform designed to automate and accelerate matching patients with clinical trials and increase access to clinical trials. Click here to read more.

Rice University has stood up a new office of innovation — and named its new leader. Paul Cherukuri, the executive director of the Institute of Biosciences and Bioengineering, the inaugural vice president for innovation. In his role, Cherukuri will "lead Rice’s technology and commercialization infrastructure to translate breakthrough discoveries into inventions for the benefit of society," per a news release from Rice.

“I am thrilled and honored to serve in this new role at this inflection point in our university’s history,” Cherukuri says in the release. “Rice has some of the finest minds in the world and I look forward to working with President DesRoches and the leadership team he has assembled to chart a bold new path for world-changing innovation from Rice by engaging the remarkable innovation ecosystem including the Ion District, the Texas Medical Center, industry and other unique assets in Houston.” Click here to read more.

Houston corporate investor on why Houston is poised to lead the energy transition

HOUSTON INNOVATORS PODCAST EPISODE 145

When it comes to Houston's potential to lead the energy transition, Jim Sledzik, North American managing director of Saudi Aramco Energy Ventures, says it's a no-brainer.

"We understand the energy business — we understand size and scale. And the size and scale of the challenges in front of us to get to net zero is enormous,” he says on this week's episode of the Houston Innovators podcast. “The basics are here. We just need to tap into the talent and experience."

Over the past decade, Saudi Aramco Energy Ventures has invested $320 million into 33 portfolio companies in the United States. Sledzik, who's worked in various energy services roles around the world before entering in to investment, explains that the corporate venture model is ideal for scaling big technology — and fast.

“When you’re using the venture model in a corporate setting, you have the company and the balance sheet behind you, which brings different benefits to companies you’re investing in,” he says. “These entrepreneurs who are looking to figure out how to deploy technology at scale becomes the real interesting item. All entrepreneurs want to grow — and they want to grow fast."

Scaling fast is risky, but big corporates — like Aramco — can help address the risks by providing a foothold in the market, a place to roll out the technology, and more.

“With corporate venture, you can bring the assets and the application of those technologies, and you can work to scale it in a manner that’s somewhat derisked,” Sledzik says on the show. “In corporate venture capital, you have other levers in which to pull to add value to the entrepreneurs you’re investing in. The private side brings different values.”

Earlier this year, Aramco announced a partnership with the Ion, representing its dedication to the Houston innovation ecosystem. Sledzik says Aramco being named a founding partner at the Ion opens the door to more collisions with Houston entrepreneurs. Starting later this month, Sledzik and his team will host office hours every other Friday.

"Ion is the place where you can find those collisions,” he says. “You just never know when serendipity is going to be created.”

He shares more about the types of technology Aramco is looking for and his advice to energy tech entrepreneurs on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

With boost from Houston, Texas is the No. 1 state for economic development

governor's cup

Texas is on a 14-year winning streak as the top state for attracting job-creating business location and expansion projects.

Once again, Texas has claimed Site Selection magazine’s Governor’s Cup. This year’s honor recognizes the state with the highest number of economic development projects in 2025. Texas landed more than 1,400 projects last year.

Ron Starner, executive vice president of Site Selection, calls Texas “a dynasty in economic development.”

Among metro areas, Houston lands at No. 2 for the most economic development projects secured last year (590), behind No. 1 Chicago and ahead of No. 3 Dallas-Fort Worth.

In praising Houston as a project magnet, Gov. Greg Abbott cites the November announcement by pharmaceutical giant Lilly that it’s building a $6.5 billion manufacturing plant at Houston’s Generation Park.

“Growth in the Greater Houston region is a great benefit to our state’s economy, a major location for foreign direct investment and key industry sectors like energy, aerospace, advanced manufacturing, and life sciences,” Abbott tells Site Selection. “Houston is also home to one of the largest concentrations of U.S. headquarters for companies from around the world.”

In 2025, Fortune ranked Houston as the U.S. city with the third-highest number of Fortune 500 headquarters (26).

Texas retained the Governor’s Cup by gaining over 1,400 business location and expansion projects last year, representing more than $75 billion in capital investments and producing more than 42,000 new jobs.

Site Selection says Texas’ project count for 2025 handily beat second-place Illinois (680 projects) and third-place Ohio (467 projects). Texas’ number for 2025 represented 18% of all qualifying U.S. projects tracked by Site Selection.

“You can see that we are on a trajectory to ensure our economic diversification is going to inoculate us in good times, as well as bad times, to ensure our economy is still going to grow, still create new jobs, prosperity, and opportunities for Texans going forward,” Abbott says.

Houston e-commerce giant Cart.com raises $180M, surpasses $1B in funding

fresh funding

Editor's note: This article has been updated to clarify information about Cart.com's investors.

Houston-based commerce and logistics platform Cart.com has raised $180 million in growth capital from private equity firm Springcoast Partners, pushing the startup past the $1 billion funding mark since its founding in 2020.

Cart.com says it will use the capital to scale its logistics network, expand AI capabilities and develop workflow automation tools.

“This investment will strengthen our balance sheet and provide us with the flexibility to accelerate our strategic priorities,” Omair Tariq, CEO of Cart.com, said in a news release. “We’ve built a platform that combines commerce software with a scaled logistics network, and we’re just getting started.”

In conjunction with the funding, Springcoast executive-in-residence Russell Klein has been appointed to Cart.com’s board of directors. Before joining Springcoast, he was chief commercial officer at Austin-based Commerce.com (Nasdaq: CMRC). Klein co-led Commerce.com’s IPO, led the company’s mergers-and-acquisitions strategy and played a key role in several funding rounds.

“The team at Cart.com has demonstrated excellence in their ability to scale efficiently while continuing to innovate,” Klein said. “I’m excited to join the board and support the company as it expands its AI-driven capabilities, deepens enterprise relationships, and further strengthens its position as a category-defining commerce and fulfillment platform.”

Before this funding round, Cart.com had raised $872 million in venture capital and reached a valuation of about $1.6 billion, according to CB Insights. With the new funding, the startup has collected over $1 billion in just six years.

This is the income required to be a middle class earner in Houston in 2026

Cashing In

A new study tracking the upper and lower thresholds for middle class households across the nation's largest cities has revealed Houstonians need to make at least a grand more than last year to maintain their middle class status this year.

According to SmartAsset's just-released annual report, "What It Takes to Be Middle Class in America – 2026 Study," Houston households need to make anywhere from $42,907 to $128,722 to qualify as middle class earners this year.

Compared to 2025, Houstonians need to make $1,153 more per year to meet the minimum threshold for a middle class status, whereas the upper bound has stretched $3,448 higher. The median income for a Houston household in 2024 was $64,361, the study added.

SmartAsset's experts used 2024 Census Bureau median household income data for the 100 biggest U.S. cities and all 50 states and determined middle class income ranges by using a variation of Pew Research's definition of a middle class household, stating the salary range is "two-thirds to double the median U.S. salary."

In the report's ranking of the U.S. cities with the highest household incomes needed to maintain a middle class status, Houston ranked No. 80.

In the report's state-by-state comparison, Texas has the 24th highest middle class income range. Overall, Texas households need to make between $53,147 and $159,442 to be labeled "middle class" in 2026. For additional context, the median income for a Texas household in 2024 came out to $79,721.

"Often, the expectations that come with the term 'middle class' include reaching home ownership, raising kids, the comfort of modest emergency funds and retirement savings, and the occasional splurge or vacation," the report said. "And as the median household income varies widely across the U.S. depending on the local job market, housing market, infrastructure and other factors, so does swing the bounds on what constitutes a middle class income in America."

What it takes to be middle class elsewhere around Texas

Two Dallas-Fort Worth suburbs – Frisco and Plano – have some of the highest middle class income ranges in the country for 2026, SmartAsset found.

Frisco households need to make between $96,963 and $290,888 to qualify as middle class this year, which is the third-highest middle class income range nationwide.

Plano's middle class income range is the eighth highest nationally, with households needing to make between $77,267 and $231,802 for the designation.

Salary range needed to be a middle class earner in other Texas cities:

  • No. 28 – Austin: between $60,287 and $180,860
  • No. 40 – Irving: between $56,566 and $169,698
  • No. 44 – Fort Worth: between $55,002 and $165,006
  • No. 57 – Garland: between $50,531 and $151,594
  • No. 60 – Arlington: between $49,592 and $148,77
  • No. 61 – Dallas: between $49,549 and $148,646
  • No. 73 – Corpus Christi: between $44,645 and $133,934
  • No. 77 – San Antonio: between $44,117 and $132,352
  • No. 83 – Lubbock: between $41,573 and $124,720
  • No. 84 – Laredo: between $41,013 and $123,038
  • No. 89 – El Paso: between $39,955 and $119,864
