Houston rises in 2026 ranking of best U.S. cities to start a business

Best for Biz

Houston has reaffirmed its commitment to a business-friendly environment and now ranks as the 26th best large U.S. city for starting a business in 2026. The city jumped up eight places after ranking 34th last year.

WalletHub's annual report compared 100 U.S. cities based on 19 relevant metrics across three key dimensions: business environment, access to resources, and costs. Factors that were analyzed include five-year business survival rates, job growth comparisons from 2020 and 2024, population growth of working-age individuals aged 16-64, office space affordability, and more.

Florida cities locked out the top five best places in America for starting a new business: Tampa, Orlando, Jacksonville, Hialeah, and St. Petersburg.

Houston's business environment ranked as the 19th best in the country, and the city ranked 51st in the "business costs" category. However, the city lagged behind in the "access to resources" ranking, coming in at No. 72 overall. This category examined metrics such as Houston's working-age population growth, the share of college-educated individuals, financing accessibility, the prevalence of investors, venture investment amounts per capita, and more.

"From the Gold Rush and the Industrial Revolution to the Internet Age, periods of innovation have shaped our economy and driven major societal progress," the report's author wrote. "However, the past few years have been particularly challenging for business owners in the U.S., due to factors such as the COVID-19 pandemic, the Great Resignation and high inflation."

Earlier this year, WalletHub declared Texas the third-best state for starting a business in 2026, and several Houston-area cities have seen robust growth after being recognized among the best career hotspots in the U.S. Entrepreneurial praise has also been extended to five local companies that were named the most innovative companies in the world, and six powerhouse female innovators that made Inc. Magazine's 2026 Female Founders 500 list.

Texas cities with strong environments for new businesses
Multiple cities in the Dallas-Fort Worth Metroplex can claim bragging rights as the best Texas locales for starting a new business. Dallas ranked highest overall — appearing 11th nationally — and Irving landed a few spots behind in the 16th spot. Arlington (No. 23), Fort Worth (No. 30), Plano, (No. 35), and Garland (No. 65) followed behind.

Only six other Texas cities earned spots in the report: Austin (No. 24), Lubbock (No. 36), Corpus Christi (No. 39), San Antonio (No. 64), El Paso (No. 67), and Laredo (No. 76).

Austin tied with Boise, Idaho and Fresno, California for the highest average growth in the number of small businesses nationally, while Corpus Christi and Laredo topped a separate list of the U.S. cities with the most accessible financing.

Houston humanoid robotics startup taps Amazon veteran to lead manufacturing

new hire

Persona AI, a Houston-based startup that’s developing AI-powered humanoid robots for manufacturers and other businesses, has hired Brian Davis as head of global manufacturing.

Davis previously guided teams at Amazon Robotics and Dell Technologies. During his tenure at Amazon Robotics and Dell, both companies saw major increases in manufacturing volumes within a four-year period. Davis oversaw manufacturing, supply chain, logistics, quality assurance and real estate.

“Davis steps into this role [at Persona AI] as industrial enterprises face an urgent and accelerating challenge: a structural shortage of capacity for welding, fabrication, and heavy maintenance in dynamic environments, precisely the high-value, high-risk tasks where humanoid robots can deliver the greatest impact,” according to a company news release.

Davis comes aboard as Persona AI, founded in 2024, seeks to meet demand generated by deals with HD Hyundai and POSCO Group to make humanoids for shipyards and steel plants, and by a pilot program with the State of Louisiana.

“Now is the perfect time to accelerate our production capabilities as we rapidly close the gap between what’s possible in the lab versus what’s driving real commercial value,” Davis says.

“Building industrial-rated humanoid robots and production-deployable AI is only one piece of the puzzle,” he adds. “Producing humanoids at scale will require systematic supply chain management, stringent quality control, and building the playbook for safe, high-volume manufacturing. That’s what I’m here to build.”

Last year, Persona AI raised more than more than $10 million in pre-seed funding. The company also named a new head of commercial strategy in March.

Houston startup’s brain implant for depression advances to clinical trial

moving forward

Houston-based Motif Neurotech has received FDA approval to move forward with its first clinical trial for its innovative way to fight treatment-resistant depression and other mental health disorders.

The company has developed a brain-computer interface technology based on research from Rice University. The blueberry-sized, wirelessly powered implantable device known as the Digitally-programmable Over-brain Therapeutic (DOT) stimulator delivers electrical stimulation to brain circuits linked to depression. The DOT stimulator sits in the skull above the dura without touching the brain and is considered an alternative to transcranial magnetic stimulation, which requires multiple treatment sessions and can cause headaches.

“The goal for this technology is that it would be the mental health equivalent of a continuous glucose monitor for diabetes,” Jacob Robinson, a Rice University professor of electrical computer engineering and bioengineering and CEO of Motif Neurotech, said in a news release. “What has been really special for me personally on this journey is to be able to work all the way from a concept through the process of research and development funded by the federal government at Rice, and take that into a product that is going to affect people’s lives for the better.”

Eligible adults whose depression has not improved after trying multiple therapies can take part in the study. The clinical trial will be conducted in collaboration with Baylor College of Medicine, Brain Health Consultants (Houston), UT Health Houston, Massachusetts General Brigham, Emory Healthcare, University of Iowa, University of Utah Health and New York University, according to Rice.

Motif also announced that it was one of the first teams selected for ARPA-H’s EVIDENT initiative, which recently awarded up to $139.4 million to spur new, effective therapies for behavioral health. Through the initiative, Motif will collect additional data alongside its clinical trial.

“The idea with this funding is to support a number of teams who have rapid-acting interventions for a mental health condition and to collect additional data to help determine with greater precision whether a treatment is working, how it is working and which patients are benefitting most from which course of treatment,” Robinson added in the release.

Motif Neurotech was spun out of Robinson’s and Professor Kaiyuan Yang’s labs at Rice, along with collaborators and co-founders Dr. Sameer Sheth at Baylor College of Medicine and Dr. Sunil Sheth at the University of Texas Health Science Center at Houston. It was founded through the Rice Biotech Launch Pad. The company closed its Series A round with an oversubscribed $18.75 million last year.
