The Woodlands-based medical device company Autonomix Medical grossed more than $11.1 million in its recent IPO.

The company’s stock now trades on the NASDAQ market under the symbol AMIX. On February 1, company officials range the NASDAQ’s closing bell. The stock closed February 5 at $5.60 per share.

The NASDAQ listing “represents a pivotal moment in the growth of our [company] and a significant corporate milestone leading to what we believe will be an exciting future for Autonomix,” says Lori Bisson, the company’s CEO.

In the IPO, Autonomix sold nearly 2.24 million shares of common stock at $5 each. The gross amount raised excludes sales commissions and other expenses.

In a January 19 filing with the U.S. Securities and Exchange Commission (SEC), Autonomix had eyed gross IPO proceeds of more than $21.2 million — nearly half of what the company actually raised — from the sale of up to 4 million shares.

For the six-month period ended September 30, 2023, Autonomix tallied a net loss of $6.9 million and a deficit of nearly $30.5 million.

Outside investors BioStar Ventures (with a 15 percent pre-IPO stake) and Tricord Holdings (5.5 percent), according to SEC documents. Before the IPO, seven Autonomix executives and directors controlled 50.6 percent of the company’s common stock.

The first medical device being developed by Autonomix, founded in 2014, is a catheter-based microchip that the company says can detect and differentiate neural signals with about 3,000 times greater sensitivity than current technology.

On its website, Autonomix cites a potential $100 billion global market for its technology.

Initially, Autonomix’s technology is geared toward treating pain stemming from pancreatitis and pancreatic cancer. Other uses for the technology, protected by dozens of patents, include management of post-surgery pain, treatment of high blood pressure, and treatment of organ-related conditions.

A day after the January 29 IPO, Autonomix announced it had wrapped up an $8 million all-stock deal to regain exclusive worldwide rights for use of its technology in the cardiology sector. In December 2021, Autonomix granted a license to Impulse Medical for use of its technology for cardiac purposes. In exchange for 1.6 million Autonomix shares, Impulse sold back those rights to Autonomix.

“Regaining the cardiology rights to our innovative technology broadens our development opportunities and provides further optionality related to our development strategy moving forward. Looking ahead, we remain focused on our pancreatic cancer pain development program and are on track to commence our first-in-human clinical study this quarter,” Bisson says.

Autonomix says its catheter-based sensing technology is designed to sense neural signals associated with pain or disease and then target those nerves for treatment.

“Autonomix believes this technology is a better alternative to the current approaches commonly used today, where doctors either rely on systemic drugs like opioids that lose effectiveness,” say the company, “and have unwanted side effects or treat suspected areas blindly in hopes of hitting the right nerves, an approach that is often inaccurate and can miss the target and even cause collateral damage to surrounding parts of the body.”

Houston regenerative medicine company to IPO, move toward more human trials

ready to list

Want a piece of one of Houston’s most promising biotech companies? On January 31, FibroBiologics will begin the trading of its common stock on the Nasdaq stock exchange.

While most labs in the realm of regenerative medicine are focused on stem cells, FibroBiologics has bet on fibroblasts as the secret to treating myriad ailments. Fibroblasts, the most common type of cell in the body, are the primary cells that compose connective tissue.

Interested investors can find a prospectus to peruse before taking the leap. FibroBiologics filed with the U.S. Securities & Exchange Commission (SEC) on November 7, 2023. In September, FibroBiologics CEO Pete O’Heeron told InnovationMap, “I think what we're going to see is that fibroblasts are going to end up winning... They're just a better overall cell than the stem cells.”

O’Heeron was first exposed to the possibilities of fibroblasts as a means of regrowing discs in the spine. Since starting the company in 2008 as SpinalCyte, O’Heeron and FibroBiologics have organically written and filed more than 320 patents. Potential treatments go far beyond spinal surgery to include wound care, cancer, and multiple sclerosis.

According to O’Heeron, the goal in going public is to raise capital for human trials.

“We’ve had really fantastic results with animals and now we’re ready for humans,” he explained in September. “We've done small human trials, but we haven't done the large ones that are going to get the commercialization approval from the FDA.”

FibroBiologics is growing with impressive speed. O’Heeron told us that he is hiring as quickly as he is able to find qualified scientists with the expertise to do the one-of-a-kind work required. The company opened a new lab last fall at the UH Technology Bridge, Newlin-Linscomb Lab for Cell Therapies. With its new status as a publicly traded company, FibroBiologics is primed to break even more ground.

Houston brain health co. secures $6.5M for rare disease study

neuro funding

Houston-based Goldenrod Therapeutics, part of Fannin Partners' portfolio, has announced the initial close of a $6.5 million series seed preferred stock round.

The round was led by Ataxia Ventures and an affiliate of Fannin, according to a news release.

Goldenrod Therapeutics plans to use the funding to support manufacturing, formulation optimization, IND-enabling studies and a Phase I study of its drug to treat brain inflammation, known as 11h.

The study will consider how 11h, which blocks the enzyme PDE4, could treat Friedreich’s ataxia (FA), a rare genetic disease that affects movement, speech and balance. To date, other PDE4 inhibitors have proven to regulate neuroinflammation and neuronal signaling, but have had adverse gastrointestinal side effects or have not reached enough of the central nervous system, according to Goldenrod.

The company says its 11h is expected to have "broad applicability" with limited emetric side effects.

“Our 11h program is a next-generation, orally bioavailable, brain-penetrant PDE4 inhibitor, where researchers overcame longstanding limitations associated with earlier PDE4 inhibitors," Dr. Dev Chatterjee, CEO of Goldenrod, said in the news release. "We believe this creates the potential for a best-in-class therapy for Friedreich’s Ataxia and a potential foundation for development across multiple neurodegenerative and neuroinflammatory disorders.”

11h was first developed at the University of Nebraska Medical Center (UNeMed). Houston-based Fannin Partners in-licensed the product 2020 and landed SBIR Phase I funding to support its initial development for opioid use disorder soon after.

Goldenrod has also received funding to study 11h's effectiveness for multiple sclerosis, methamphetamine addiction and cocaine addiction.

Goldenrod says it is developing 11h to target a variety of neurological and inflammatory conditions, including Alzheimer's disease, multiple sclerosis, ALS, substance use disorders, Batten disease, pain and traumatic brain injury.

27 Houston companies make Fortune 500 for 2026, led by energy giants

Houston HQs

Editor's note: This article has been updated to correct the number of companies based in the Dallas-Fort Worth area.

Houston is a giant among U.S. hubs for corporate headquarters.

The 2026 Fortune 500 lists 27 companies based in the Houston area, with many energy companies claiming top spots. Houston ties with Chicago for the second-most Fortune 500 headquarters, preceded only by New York City (53). Dallas-Fort Worth is home to 24 Fortune 500 headquarters.

Texas leads the nation for Fortune 500 headquarters (57), with California in the No. 2 spot and New York at No. 3.

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

The 2026 Fortune 500 ranks the largest U.S. corporations based on revenue in fiscal year 2025.

The Greater Houston Partnership notes the Houston area soon will welcome its 28th Fortune 500 company. Expand Energy (formerly Chesapeake Energy), appearing at No. 362 on the 2026 list, says it’s moving its headquarters from Oklahoma City to Spring this year.

As the natural gas producer prepares to relocate to Texas, it’s hunting for a new leader. Nick Dell’Osso stepped down as president and CEO earlier this year. Board Chairman Michael Wichterich is interim president and CEO.

Dell’Osso became president and CEO of Oklahoma City-based Gulfport Energy effective May 28.
