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)

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.

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
