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.

Houston named among the best large cities for early-stage startups

Start up here

When it comes to cities with over a million residents, Houston's at the front of the pack, according to a new study. But, there's a catch.

Last month, Commercial Cafe rounded up the 20 top cities for early-stage startups and entrepreneurs, and Houston missed the list. Now, the commercial real estate blog has broken down the data into three top ten lists based on city size, and Houston has claimed the No. 5 spot on the list of cities with 1 million or more residents.

The study took into account education, affordability, startup financial success (calculated from Kickstarter data), millennial population growth, among other aspects. Houston in particular was called out for being the most affordable major metro and for having the third best startup survival rate.

"The city is home to the fourth-largest percentage of millennial residents out of the total population, and saw the fourth-largest growth in number of millennial residents," the report reads. "Houston ranked fifth in group for the share of population holding a bachelor's degree or higher in a tech discipline. The rate at which the number of such residents has increased placed Houston seventh for tech education growth."

Outpacing Houston on the larger cities were Dallas at No. 1, San Diego, California, at No. 2, San Jose, California, at No. 3, and Los Angeles at No. 4. San Antonio also made the list, coming in at No. 7.

Texas cities were sprinkled throughout the two smaller cities list. Austin came in at No. 1 for the cities with 500,000 to 1 million residents, as well as claimed the top spot in the best cities regardless of population. Fort Worth ranked as No. 10 on this mid-sized city list.

On the small cities list for metros with less than 500,000 residents, Arlington came in at No. 6 for its location and startup density. The city also made the top 20 regardless of size, sliding into the No. 19 spot. Dallas, which topped the large cities list, came in at No. 15 on the size agnostic list for top startup cities.

Recently, Texas was named a top city to start a company by personal finance website, WalletHub, based on similar statistics.

"[I]t's clear why Texas would come in at No. 1," Susan Davenport, senior vice president of economic development for the Greater Houston Partnership, says responding to that study. "These are all areas where the Lone Star State consistently excels and why Texas continues to attract both entrepreneurs and existing companies across industry sectors."

The Cannon and Capital Factory announce new Houston-based partnership

Teaming up

Two major players in the Texas innovation ecosystem are teaming up for a partnership in Houston.

The Cannon, which is expected to open its 120,000-square-foot space later this summer, announced a partnership with Austin-based Capital Factory, a tech accelerator. The partnership will give Capital Factory space in The Cannon to provide remote mentorship and local programming for its Houston-based companies for six months throughout the cohort.

This alliance allows for more collaboration between Houston companies and mentors and resources across the state.

"The Texas Startup Manifesto is about leveraging the entire Texas startup ecosystem while honoring the unique contributions of each city and region," says Gordon Daugherty, co-founder and president of Capital Factory, in a release. "We can't deliver on that vision in Houston without the help of local partners like The Cannon and their collaborative attitude really sets them apart."

Capital Factory recently entered the Dallas market with the opening of a location in partnership with The Dallas Entrepreneur Center.

This new office space will result in two new hires for Capital Factory — both will be responsible to advancing the Texas-wide program. A venture associate position will be created to recruit and educate local companies. The associate will also find potential investments for the accelerator's venture fund, which has already invested in several Houston startups, including Apartment Butler, Groupraise, Hypergiant, and Zenus Biometrics in 2018.

The second new hire will be a mentor coordinator to seek out new mentors — not necessarily in Houston, as mentors can access startups through a software platform.

Capital Factory's space in The Cannon will be a branded office complete with Cisco Webex video conferencing equipment, according to the release, so that local Capital Factory startups can connect to mentors across the state. As an added plus, the entrepreneurs can also have access to The Cannon community, and vice versa. Capital Factory will also host events at The Cannon.

"We're thrilled that this partnership with Capital Factory will connect Houston startups with more resources," says Lawson Gow, founder and CEO of The Cannon, in the release. "These companies will have a chance to join an incredibly valuable network, and in return, Capital Factory will have the opportunity to invest in Houston's booming startup scene and diverse talent pool." (Gow is the son of InnovationMap's CEO.)

Houston startups stand to benefit from this partnership, according to Aaron Knape, co-founder and CEO of Houston-based sEATz, who says he's already seen the benefit of the alliance.

"The Cannon and Capital Factory's partnership has proven to be a game-changing resource for us, giving our team access to Capital Factory's incredible Accelerator platform while allowing our company to remain in Houston and continue to receive all of the benefits of The Cannon's growing entrepreneurial community," Knape says in the release.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.
