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.

How a Houston company is fighting anxiety, insomnia & Alzheimer’s through waveforms

mental health

A Houston-based company is taking a medicine-free approach to target brain neurologically associated with mental illness.

Nexalin Technology’s patented, FDA-cleared frequency-based waveform targets key centers of the midbrain to support the normalization of neurochemicals through a process known as Transcranial Alternating Current Stimulation (tACS). Delivered via a non-invasive device, the treatment gently stimulates the hypothalamus and midbrain, helping to “reset networks associated with symptoms” of anxiety and insomnia. Early clinical evidence suggests this approach can promote healthier brain function and improved sleep.

Through its recently appointed scientific advisory board (SAB), Nexalin also aims to target Alzheimer’s disease with a clinical development pipeline supported by published data and internal data from studies involving its proprietary DIFS technology. Nexalin’s Gen-2 SYNC and Gen-3 Halo headset delivers the DIFS, which is a waveform that can penetrate deep brain structures implicated in cognitive decline and mental illness.

The board includes experts in neurology, neuroimaging and neurodegenerative diseases with Dr. Mingxiong Huang, Dr. David Owens, and Dr. Abe Scheer coming on board. Nexalin plans to initiate new Alzheimer’s-focused clinical studies in the Q3 2025 by incorporating cognitive testing, imaging biomarkers, and guided metrics to assess treatment efficacy and neural activation.

“I am excited to work alongside Nexalin’s leadership and fellow SAB members to help guide the next generation of non-invasive neuromodulation therapies,” Huang said in a news release. “The intersection of neuroimaging, brain stimulation, and clinical science holds enormous potential for treating neurodegenerative disease.”

Recently, Nexalin’s proprietary neurostimulation device moved forward with a clinical trial that evaluated its treatment of anxiety disorders and chronic insomnia in Brazil. The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices was shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria University Hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia. The Nexalin Gen-2 15-milliamp neurostimulation device has also been approved in China, Brazil and Oman. Its Gen 1 device first received FDA clearance in 2003, according to the company's website.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population.

Nexalin previously raised $5 million through a public stock offering.

Houston regenerative medicine company expands lab for future trials

new digs

A Houston regenerative medicine company has unveiled new laboratory space with the goal of expanding its pioneering science.

FibroBiologics uses fibroblasts, the body’s most common type of cell, rather than stem cells, to help grow new cells. Fibroblasts are the primary variety of cells that compose connective tissue. FibroBiologics has found in studies that fibroblasts can be even more powerful than stem cells when it comes to both regeneration and immune modulation, meaning they could be a more versatile way forward in those fields.

In 2023, FibroBiologics moved into new lab space in the UH Technology Bridge. Now, with its new space, the publicly traded company, which has more than 240 patents issued or pending, will be even better equipped to power forward with its research.

The new space includes more than 10,000 square feet of space devoted to both labs and offices. The location is large enough to also house manufacturing drug product candidates that will be used in upcoming trials. Additionally, the company reports that it plans to hire additional researchers to help staff the facility.

“This expansion marks a transformative step forward for our company and our mission,” Pete O’Heeron, FibroBiologics founder and CEO, said in a news release. “By significantly increasing the size of our lab, we are creating the space and infrastructure needed to foster greater innovation and accelerate scientific breakthroughs.”

The streamlined, in-house manufacturing process will reduce the company’s reliance on external partners and make the supply chain simpler, O’Heeron added in the release.

Hamid Khoja, the chief scientific officer for FibroBiologics, also chimed in.

“To date, our progress in developing potentially transformative therapeutic candidates for chronic diseases using fibroblasts has been remarkable,” he added in the release. “This new laboratory facility will enable further expansion and acceleration of our research and development efforts. Additionally, the expansive new space will enable us to bring in-house currently outsourced projects, expand our science team and further contribute to the increased efficiency of our R&D efforts.”

This news arrives shortly after a milestone for the company in its research about neurodegenerative disease. Last month, fibroblast treatments in an animal model study demonstrated a notable regeneration of the myelin sheath, the layer that insulates nerves and is worn down by disease.

“Confirming remyelination in a second validated animal model is an important step in our research and development efforts, offering fresh hope for patients with demyelinating diseases, including multiple sclerosis,” O’Heeron added in a separate release. “These findings advance our mission to develop transformative fibroblast-based therapies that address the root causes of chronic disease, not just their symptoms, and reflect our dedication to pushing the frontiers of regenerative medicine."

How this Houston innovator is using his personal connection to ALS fuel his fight for a cure

guest column

We can never predict how our lives will turn out, but then maybe some of us can. Genetic testing showed that I, like my grandfather, aunt, uncle and father before me, would most likely die of amyotrophic lateral sclerosis, more commonly known as ALS, and/or frontotemporal degeneration (FTD) in my 40s.

Being 36, it’s possible that fear could have overtaken my life, but instead I chose to fight for every chance to change not only my life, but the lives of millions who are suffering or may one day suffer from neurodegenerative disease.

ALS is a rare disease that robs one of their ability to control their muscles, leading them to lose their ability to walk, talk and eventually breathe. Eighty percent of cases are sporadic (of unknown origin) and 20 percent have known genetic causes.

When I learned that I carried the C9ORF72 genetic variant, a causative genetic variant for ALS/FTD) my first instincts were to help others understand their status and where they could turn for help. I saw a vacuum for resources and understanding in the genetic ALS space and I knew that thousands were suffering in darkness.

Through the efforts of many, we created the first ever nonprofit – Genetic ALS & FTD: End the Legacy – focused on fighting for the genetic ALS and FTD communities. After making great strides to fight for our rights and access to care, I was asked if I could help my current CEO, Howard Berman, commercialize Dr. Stanley Appel’s regulatory T Cell (Treg) therapy for ALS.

I joined Coya Therapeutics in 2021 as the first employee, working to build a company that would one day bring life changing therapies to patients. Coya’s therapies are based on Dr. Appel’s discovery that neurodegenerative diseases drive an inflammatory response. As inflammation rises, it damages regulatory T cells, and when Tregs are damaged, inflammation becomes a persistent condition driving degeneration and eventually death.

It was at that point that my life changed from the advocacy world to the therapeutic world. Now over three years later, we are closer than ever to making a paradigm change for how patients with ALS and other neurodegenerative diseases are treated.

At Coya, we believe that combination biologics are the future of treating neurodegenerative diseases. COYA 302 is our lead asset, which has shown promising results in a proof-of-concept study released in March of 2023. We are currently working towards a double-blind, placebo-controlled trial for COYA 302 in ALS set to kick off later this year.

I never wanted to live a life so damned by disease, but when put between a rock and a hard place, the only choice is to fight. I don’t know how my life will end, but I hope that my children will know that I faced a great challenge head on with pride and resilience.

In the end, it is the combination of both the worlds I work in that lead to better outcomes for patients, raising awareness and lifesaving research. This ALS Awareness Month, please join us and our partners like the ALS Association, End the Legacy, and I AM ALS in raising awareness about these conditions, their risks, and treatment options.

Houston ranks No. 2 for share of AI talent in professional services

AI surge

Houston’s professional and business services sector—think law, accounting, consulting, and engineering firms—grabs one of the industry’s biggest shares of AI talent.

A report from commercial real estate services giant CBRE ranks Houston No. 2 among the top 50 U.S. and Canadian tech markets for the concentration of AI talent in professional and business services.

Houston’s share of AI talent in professional and business services stands at 26 percent, the report shows. Washington, D.C., tops the list at 31 percent. At 25 percent, Dallas-Fort Worth claims the No. 3 spot.

CBRE based the AI ranking on data from the LinkedIn networking platform.

The company’s researchers tallied 11,709 AI-related tech jobs in Houston. Nationwide, data scientists lead AI-related job growth in the U.S., according to the report.

“AI software and hardware developers are currently the most sought-after tech talent by employers,” the report says.

Houston faces AI talent gap

DoubleTrack, a provider of AI and data consulting, reported in June that Houston faces an AI talent gap.

“The places where businesses say they will adopt AI over the next six months, well ahead of where they are today, are mostly the same places already short on talent: Miami, Houston, and Denver among the metros, South Dakota and South Carolina among the states,” DoubleTrack said.

This labor shortage comes amid Houston’s ascent as an AI hub. For instance, a factory being built here by AI chipmaker NVIDIA and electronics manufacturer Foxconn will produce AI supercomputers and infrastructure systems.

Houston’s place in the sphere of tech talent

Overall, Houston ranks No. 32 in the CBRE report among the top 50 U.S. and Canadian markets for tech talent. The San Francisco Bay Area claims the top spot, with Austin at No. 5 and DFW at No. 8.

CBRE relied on 13 metrics to rank tech talent markets, including concentration of tech talent, tech talent pipeline, and research-and-development investments.

Here are other Houston details from the report:

  • In 2025, Houston’s tech talent workforce numbered 104,080, up 7.3 percent over the past three years.
  • Houston’s average wage for tech talent within the tech industry was $120,216 in 2025, up 13.3 percent over the past three years.

New pilot program for air taxis, Project Nexus, takes flight in Texas

Project Nexus

By 2029, Texas skies could be buzzing with air taxis, much like they are with drones today.

To kick off the "Project Nexus" pilot program in Texas, U.S. Transportation Secretary Sean Duffy, U.S. Sen. Ted Cruz, and Texas Department of Transportation officials attended an event September 10 at Fort Worth Alliance Airport, which serves as the launchpad for a statewide pilot program that could result in air taxis, self-piloted planes, and vertical take-off-and-landing aircraft permanently buzzing across the skies of Texas.

It was the first demonstration in Texas of next-generation aircraft under the pilot program; Texas is the sixth state to participate in the program.

Air taxi service on the radar
The federal government has teamed up with aviation companies BETA Technologies and Joby Aviation, as well as the Texas Department of Transportation, to develop regional air taxi service in Dallas, Austin, San Antonio, and eventually Houston.

Roger Venables, Fort Worth’s aviation director, said in January that he foresees regular air taxi service becoming a reality in the next five years.

On September 12, a Joby-made electric air taxi took a roundtrip flight between Fort Worth Alliance and Dallas Fort Worth International Airport to test flight operations.

The mission was part of a five-day test involving Fort Worth Alliance and DFW Airport flights, and flights over the Fort Worth Stockyards, Toyota Motor North America’s Plano headquarters, and other sites.

A new facility at Fort Worth Alliance will be Joby’s long-term home for regional flight operations.

Building a 'framework' for electric aircraft
TxDOT said Project Nexus is aimed at creating “a scalable system” to connect urban areas, rural communities, and neighboring states as air mobility technology advances.

In a TxDOT release, Marc Williams, the agency’s executive director, said the pilot program will “build a framework for how electric aircraft could one day connect people, goods, and communities across the state.”

Three-phase project will test flight capabilities

Initial flights in the third-year pilot program won’t carry passengers, according to TxDOT. Instead, the flights will gather data, validate air travel routes, and help improve the safety of air mobility technology.

The first phase of the U.S. Department of Transportation’s Project Nexus will feature piloted aircraft such as helicopters and fixed-wing planes. CultureMap previously reported Plano-based VertiPorts by Atlantic, which develops takeoff and landing sites for airplane-helicopter hybrids, would be part of Project Nexus.

The second phase will involve testing airborne medical and cargo logistics. This includes transporting critical medical supplies or donor organs between rural and urban hospitals in the Austin and San Antonio areas.

In the third and final phase, passengers will fly aboard air taxis across the Texas Triangle. Dallas-Fort Worth, Austin, Houston, and San Antonio anchor the triangle.

“In Texas, we don’t wait for the future to arrive, we build it,” Cruz said in the TxDOT release. “The Lone Star State is pushing the boundaries by testing the next generation of aircraft through Project Nexus.”

“These technologies will connect communities, expand access to jobs and services, and strengthen supply chains,” the senator added. “What starts in Texas will help shape the future of aviation throughout the entire country.”

Houston-area NASA contractor plans Nasdaq IPO

going public

Webster-based NASA contractor Rothe Development Inc. has filed paperwork with the U.S. Securities and Exchange Commission to go public.

Rothe, a minority- and woman-owned business, hasn’t yet identified how many shares it will sell and how much money its IPO might raise. Rothe plans to offer Class B common stock on the Nasdaq exchange.

CEO Karen Wheeler-Hall owns all of the Class A shares and would retain majority control after the IPO, according to the SEC filing. The company plans to use $2.4 million of the IPO proceeds so Wheeler-Hall can pay off a loan from the seller for her 2021 acquisition of Rothe.

From last December to this May, the company raised about $2.1 million in a pre-IPO private placement at $1 per share, the SEC filing shows.

Rothe runs NASA training lab in Houston

Founded in 1967, Rothe supplies engineering, technology, operations and technical services to NASA, the U.S. Department of Defense, other federal agencies, commercial space operators, and regulated industries.

Rothe is likely best known for operating NASA’s Neutral Buoyancy Laboratory in Houston. The lab trains astronauts for spacewalks and simulates space missions. It supports NASA’s International Space Station and Artemis programs.

Company sees room for growth

In the SEC filing, Rothe said it operates in several expanding markets driven by rising investments, including space exploration, national security, cybersecurity and digital infrastructure.

“We believe these market trends create significant opportunities for continued growth across both government and commercial sectors,” the company said.

Rothe generated nearly $126.4 million in revenue last year, up from $117.3 million the previous year. However, the company swung to a $700,000 operating loss in 2025 versus $1.8 million in operating income in 2024.

At the end of 2025, Rothe’s workforce comprised 385 employees and 25 subcontractors. The company also works in the cybersecurity, computer engineering, software development, multimedia and communication, and commercial calibration sectors, according to its website.
