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.

  1. Caris (Dallas)
  2. Apptronik (Austin)
  3. Sage Geosystems (Houston)
  4. HiddenLayer (Austin)
  5. Fervo Energy (Houston)
  6. Plus One Robotics (San Antonio)
  7. Diligent Robotics (Austin)
  8. HighRadius (Houston)
  9. LTK (Dallas)
  10. 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.

Three Harris County officials are pushing for greater local control over the development and operation of data centers.

County Attorney Abby Kamin, County Commissioner Lesley Briones and County Commissioner Adrian Garcia recently called for action to give Harris County more power to regulate data centers.

As it stands now, Harris County “has little to no authority” over the construction of data centers, Briones said at a news conference. Harris County has 55 operating, under-construction, or planned data centers, according to a document filed with the county.

Briones outlined four steps being included in the Harris County commissioners’ exploration of potentially tighter local regulation of data centers:

  • Reviewing what Harris County can and cannot do regarding data centers
  • Creating a Harris County plan for the upcoming state legislative session aimed at granting more local control over data center construction and operations. State lawmakers would need to approve any changes in local control.
  • Establishing community “listening” sessions in Harris County about data centers
  • Notifying Harris County commissioners when a proposed data center seeks permits

Kamin noted Houston and Harris County lack zoning regulations, and the county’s 34 cities set their own zoning rules. Furthermore, she said, Texas Attorney General Ken Paxton has not issued a ruling on whether counties can impose a moratorium on development of data centers.

However, she said, “limited jurisdiction does not mean limited responsibility … New technology is arriving in our communities faster than our laws and institutions can keep up with, whether that’s data centers, AI or even drones.”

The effort by Kamin, Briones, and Garcia follows Gov. Greg Abbott’s recent statewide halt of new environmental and construction permits for data centers. State permitting is frozen until the Electric Reliability Council of Texas (ERCOT) and the Public Utility Commission of Texas complete their review of data centers.

Their initiative also comes amid growing public concern over the amount of electricity and water gobbled up by data centers, as well as residents’ own rising electric and water bills.

Houston-based CenterPoint Energy expects to connect 8 gigawatts of new data-center loads in the Houston area by 2029, with about 4 gigawatts to follow, Kamin said. That, she said, would significantly increase peak power demand.

“No industry should get to monopolize or run roughshod over residents, public safety, and our critical natural resources,” Kamin said.

That being said, Kamin and Briones stressed they take pride in Houston being the Energy Capital of the World and Texas being an economic powerhouse.

“This isn’t about being against technology or new technology, but growth has to go hand in hand with accountability,” Kamin said.

Garcia said he’s open to welcoming data centers as good corporate neighbors, but not without protecting the people who live near these projects.

“I’ll keep an open mind,” he said, “but I want to know what will ultimately be the benefit to the community. And right now, I need tools [to do that].”
