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.

Arti Bhosale, co-founder and CEO of Sieve Health

Sieve Health is an AI cloud-based SaaS platform designed to automate and accelerate matching patients with clinical trials. Photo

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.

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.

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.

2 Houston suburbs rank among 10 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

No. 1 – Midland, Michigan
No. 2 – Homosassa Springs, Florida
No. 3 – Weirton, West Virginia
No. 4 – The Woodlands
No. 5 – Spring, Texas
No. 6 – Rio Rancho, New Mexico
No. 7 – Altoona, Pennsylvania
No. 8 – Paducah, Kentucky
No. 9 – Lynchburg, Virginia
No. 10 – Palm Coast, Florida

Air taxi network to land in 'Texas triangle' of Houston, Austin, DFW next year

taking flight

San Jose, California-based aerospace company Archer Aviation is bringing its air-taxi system to the “Texas triangle” of Houston, Austin and Dallas-Fort Worth.

Currently, the planned zero-emission electric air taxi networks will use Archer’s Midnight air taxi to “turn 60- to 90-minute drives to major airports, business districts and major destinations into 10- to 20-minute flights,” the company said in a news release. Archer plans to begin flights in the Texas triangle next year.

The Midnight air taxi is an all-electric vertical takeoff and landing (eVTOL) aircraft. It can carry four passengers and a pilot and is designed for consecutive flights of about 20 miles.

Archer cites the Texas triangle as one of the busiest and fastest-growing “megaregions” in the country due to its proximity to coastal regions, major airports, and a number of business districts.

Archer Chief Commercial Officer Nikhil Goel described the air taxi experience to CW Houston as “100 times quieter than a helicopter for the price of an Uber Black.” He added that the air taxis are a combination of a helicopter, a small airplane and a drone.

In Houston, Archer’s air taxi network will aim to connect George Bush Intercontinental, William P. Hobby and Sugar Land Regional Airport with downtown destinations, including the Thompson Hotel helipad, and Galveston.

In Austin, it plans to link the city's Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas. Archer debuted its Midnight aircraft at the F1 Prix in the Fan Zone and the F1 Paddock at Austin’s Circuit of the Americas. The Dallas-Fort Worth network is slated to include Dallas-Fort Worth International Airport, Dallas Love Field, Addison Airport, Arlington Municipal Airport, Fort Worth Meacham International Airport and Perot Field Fort Worth Alliance Airport, plus major business hubs like Frisco Station.

“Texas is setting the bar for America’s leadership in the next generation of aviation,” Adam Goldstein, founder and CEO of Archer Aviation, said in the release. “Our planned networks will make the benefits of electric air taxis real for Texans — trading hours in traffic for minutes in the air, while connecting the biggest airports, business districts and sporting hubs in ways that America’s largest megaregion needs to grow.”

Archer is working with state and local partners to develop charging infrastructure and plans to pursue Texas operations through the White House’s eVTOL Integration Pilot Program, according to the release. It recently completed its "No Roads" flight tour, which included multiple flights over the San Francisco Bay, and flew to seven cities over three days.
