3 Houston startups named most innovative in Texas by LexisNexis

report card

Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

“Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

Caris (Dallas)
Apptronik (Austin)
Sage Geosystems (Houston)
HiddenLayer (Austin)
Fervo Energy (Houston)
Plus One Robotics (San Antonio)
Diligent Robotics (Austin)
HighRadius (Houston)
LTK (Dallas)
Eagle Eye Networks (Austin)

Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.

3 Houston tech companies recognized for creating top inventions of the year

best of the rest

Innovations from three Houston companies have been crowned among the top inventions of the year.

Time magazine’s "200 Best Inventions of 2024" identified top innovations across consumer goods, home health, robotics, sustainability, and two dozen other categories.

Fervo Energy, a provider of geothermal power, was recognized the Green Energy category for its FervoFlex system. As Time explains, the system enables horizontal drilling into hot rock under the earth’s surface and pumping in water to generate hot water and steam. The geothermal energy that’s produced can be stored and released for future use by Fervo customers.

Jack Norbeck, Fervo’s co-founder and chief technology officer, predicts that by 2050, geothermal energy will become “the backbone of the decarbonized energy system.”

In September, Fervo secured a $100 million bridge loan for the first phase of its ongoing Cape Station project in Utah, which is being touted as the world’s largest geothermal energy plant. Slated for completion in June 2026, this initial phase is expected to generate 90 megawatts of renewable energy. Ultimately, the plant is supposed to supply 400 megawatts of clean energy by 2028 for customers in California.

Time also lauded NanoTech Materials among its Manufacturing and Materials honorees for its Insulative Ceramic Particle. This powder can be added to materials like drywall or shingles to improve fire resistance and decrease heat penetration, according to Time. NanoTech’s Wildfire Shield coating for buildings contains the powder. Wildfire Shield prevents damage to materials and harm from noxious smoke.

NanoTech’s other product, Cool Roof Coat, is painted on a building to decrease HVAC use. This year, NanoTech moved into a 43,000-square-foot space in Katy, Texas, and brought on new partners that expanded the company's reach in the Middle East and Singapore.

The third Houston company to be praised by Time is BiVACOR — named to its Experimental category of the list. This year, the company’s artificial heart has kept three U.S. patients alive long enough to wait for donor organs, according to Time, the first of these operations took place this summer in Houston.

Dr. William Cohn, chief medical officer of BiVACOR, previously told InnovationMap that while the Total Artificial Heart is being used currently as a "bridge-to-transplant" device, he believes it has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

The full list of this year's top inventions is available online.

Houston businesses score spots on prestigious list of most influential companies

leading the pack

Five companies with strong ties to Houston have been named among this year’s 100 most influential companies by Time magazine.

The five companies are:

South Korea’s Hanwha Group, whose Hanwha Power Systems Americas subsidiary is in Houston. Hanwha, known as the “Lockheed Martin of Asia,” was praised for winning approval last year from the American Bureau of Shipping for the world’s first large-scale, carbon-free liquefied natural gas (LNG) vessel.
Houston-based Intuitive Machines. In February, the company’s Odysseus spacecraft became the first commercial spacecraft to land on the moon. The feat also marked the first U.S. landing on the moon since 1972.
Saudi Aramco, whose Americas headquarters is in Houston. Time cited Saudi Aramco’s dominance in the global oil market as a $1.9 billion “giant.”
Germany-based ThyssenKrupp Nucera, whose U.S. headquarters is in Houston. The company builds alkaline water electrolyzers to power steel mills and other fossil-fuel-dependent industrial sites.
United Airlines, which operates a hub at George Bush Intercontinental Airport. Chicago-based United was lauded for funding startups that help produce sustainable aviation fuel.

To come up with the fourth annual list, Time solicited nominations and polled in-house contributors and correspondents, along with external experts. Editors at Time then evaluated each company based on factors such as impact, innovation, ambition, and success.

“The result is a diverse group of 100 businesses helping chart an essential path forward,” the magazine says.

In a news release, Time’s editor in chief, Sam Jacobs, says the list of 100 companies “is more than an index of business success.”

“It is an argument for what business influence looks like in 2024,” Jacobs adds. “At a time when leadership in other sectors is battered, surveys suggest that many look to corporate leaders first for direction …. Each show us how companies can provide new models and new inspiration for the future of humanity.”

UH, Rice join other Texas universities in new ranking of best schools for future leaders

top of class

Two Houston schools just scored spots on a new list recognizing universities that are fostering future leaders.

TIME Magazine revealed its inaugural “Best Colleges For Future Leaders,” and the University of Houston and Rice University were recognized in the top 100 with UH coming in at No. 88 and Rice taking the No. 90 spot.

TIME and Statista analyzed the resumés of 2,000 top leaders in the U.S. like politicians, CEOs, Nobel winners, union leaders and more across various sectors to curate a list of the universities and colleges where they received their degrees.

The list is weighted for school size, and is led by “Ivy Plus schools'' like Harvard University — the No. 1 ranking. In addition, the top-ranked schools on the list also have business and law programs, and large research universities.

“Being recognized as one of the best colleges for future leaders is a testament to the University of Houston’s unwavering commitment to excellence in education,” Diane Chase, UH senior vice president for academic affairs and provost, says in a news release. “This ranking reflects our dedication to research and innovation, encouraging diverse perspectives and nurturing the next generation of leaders who will shape a dynamic future for society.”

UH was also ranked as No. 44 of the top 50 public universities for “Best Value” by The Princeton Review.

UH, UT Austin (No. 14) and Texas A&M (No.23) were the only public institutions in Texas on the list, and Rice, Baylor (No. 40), and Trinity University (No. 62) also cracked the top 100.

The two schools also recently shared an accolade from The Princeton Review. Each school ranked No. 1 for entrepreneurship — UH for the undergraduate list and Rice for the graduate ranking.

UH secures $5M in philanthropic gifts to bolster engineering, nursing

major gifts

The University of Houston has received two significant philanthropic gifts to advance innovation and healthcare, the college announced this month.

Manmohan Singh Kalsi and Marie-Luise Schubert Kalsi granted $4 million to UH’s Cullen College of Engineering to support endowed and current funds for graduate fellowships and industry interest in the mechanical and aerospace fields.

The gift is the Department of Mechanical and Aerospace Engineering’s largest donation in years, according to UH, and will establish two endowed professorships to attract and retain leading faculty. It will also create the Kalsi Faculty Research Fund, which aims to take emerging research to the next level.

Additionally, UH says it will also bring industry experts to campus to present and collaborate with students via the forthcoming Kalsi Seminar Series.

Manmohan Kalsi earned both his master’s degree and Ph.D. in mechanical engineering from UH. He went on to found Sugar Land-based Kalsi Engineering in 1978, which pioneered hydrodynamic rotary sealing technology and valve technology for nuclear power plants. In 2014, he established an endowed professorship within Cullen College in honor of the late UH professor Gabriel Fazekas.

"This gift provides a tremendous boost to our department's strategic momentum,” Karolos Grigoriadis, chair of the Department of Mechanical and Aerospace Engineering, said in a news release. “By simultaneously supporting faculty, graduate researchers and collaborative seminars, the Kalsis are strengthening every part of our research enterprise and creating new opportunities for discovery, collaboration and student mentorship.”

Meanwhile, Houston’s The Hamill Foundation also gave a $1 million gift to UH’s Andy and Barbara Gessner College of Nursing. The funds will establish The Hamill Foundation Endowed Professorship in Community Care Nursing, to support a faculty member focused on community-based nursing education, partnerships, research, and outreach to underserved communities in Houston.

Additionally, the funding will go toward efforts to address nurse shortages through the newly established UH Health program. The Hamill Foundation has donated $6 million previously to UH through the years, but the latest $1 million is the largest single investment from the foundation to date.

“The Hamill Foundation continues to help us raise the bar for nursing education and address the nursing shortage,” Kathryn Tart, founding dean and professor at Gessner College and Humana Endowed Dean's Chair in Nursing, said in a news release. “The enduring commitment and generosity of The Hamill Foundation allow us to answer the call and educate generations of competent and caring nursing professionals.”

Both of the recent gifts help fund UH’s $1 billion Can’t Stop Houston: The Centennial Campaign. As of September, the university had raised more than $881 million. UH turns 100 years old in March 2027.

SpaceX's supersized Starship rocket launches into orbit for first time

Out in Space

SpaceX launched its enormous Starship into orbit for the first time Monday, September 28, and successfully delivered the most advanced Starlink satellites yet, but cut the flight short to ensure safety.

The spacecraft reentered over the Pacific and splashed down north of Hawaii three hours after blasting off from Texas. The company had been aiming for a 10-hour flight, spanning six full laps around Earth, to prove its readiness for NASA’s Artemis moon program.

Starship tipped over and erupted in flames upon splashdown, a dramatic end to the mission.

Elon Musk's Starship almost didn't make it to orbit when one of its engines shut down prematurely. But with everything else working well and the bad engine no longer needed, flight controllers decided, after several tense minutes, to proceed as planned.

“Starship is orbital,” Mission Control announced to cheers.

NASA Administrator Jared Isaacman congratulated SpaceX on reaching orbit and “managing every step in a safe, responsible and especially inspirational way.”

Rocket carries 26 of Musk's most advanced Starlink satellites

Musk’s showpiece rocket — the biggest and most powerful ever built — carried 26 of the latest Starlinks to join the 11,000 older models already providing internet service. They popped out of the spacecraft one by one, drawing more cheers from the SpaceX crowd at the Starbase launch site.

The decision to end the flight early came soon afterward. SpaceX said hours later in an online update that the decision was made “out of an abundance of caution” because of the early engine trouble.

It was Starship’s 14th full-scale launch from Texas’ southern tip in three years. Earlier test flights ventured no farther than the Indian Ocean halfway around the world, often crashing in flames and briefly skimming space.

This time, the intent was for SpaceX to circle the globe from an altitude of 170 miles (275 kilometers) — not just once but six times over almost 10 hours, ending with a Pacific splashdown near Chile. While Starship achieved the proper orbit, zipping along at 17,500 mph (28,000 kph), flight controllers opted to play it safe and bring it back several hours sooner, after just a couple of laps.

The first-stage booster was never meant to return to the Starbase launch site either, dropping instead into the Gulf of Mexico within minutes of the morning liftoff.

SpaceX wants to ensure that everything works before flying Starship back to Starbase. If the spacecraft breaks apart over land and rains debris onto people, “our popularity would diminish very rapidly,” Musk said at a business summit earlier this month. “That’s why we’re being extremely cautious here.”

Depending on the findings from Monday's orbital debut, the next Starship could return to the launch pad, where giant mechanical arms would grab the hovering spacecraft. If the catch works — Musk gives it even or slightly better odds — then SpaceX will refly the spacecraft by year’s end or early next year.

The 407-foot (124-meter) rocket was designed from the start to be fully reusable, a key to lowering launch costs. SpaceX managed to salvage the last Starship from the Indian Ocean in July. Engineers modified the newly launched Starship’s heat shield based on hands-on inspections of the recovered spacecraft, which is being tugged back to Starbase.

SpaceX wants Starship to be certified for orbital flight

SpaceX is pressing hard to certify Starship for orbital flight, a vital step toward moon and Mars travel.

NASA’s Artemis III mission is coming up as soon as next summer, a triple-launch docking exercise in orbit around Earth between an Orion capsule full of astronauts and competing lunar landers. Jeff Bezos’ Blue Moon would blast off first, followed by Orion — which would close in for a linkup — and then Musk’s Starship for a docking with Orion once Blue Moon is unleashed.

The next mission, Artemis IV, is slated for no sooner than 2028 and would have astronauts landing on the moon in either Blue Moon or Starship, whichever is ready first. Subsequent moonshots will alternate between the two billionaires’ landers.

Musk originally developed Starship for Mars, intending to launch scores of them with the red planet’s first settlers. For now, he plans to focus on the moon and use Starship to haul satellites into orbit by the truckload, phasing out the company’s frailer Falcon 9 rocket within several years. A second Starship launch site is nearing completion at Florida’s Kennedy Space Center and a third is planned for Louisiana.
