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.

New Texas Stock Exchange officially begins trading in Dallas

Welcome to Y'all Street

Two-step aside, New York Stock Exchange and Nasdaq. The Dallas-based Texas Stock Exchange, nicknamed Y’all Street, just kicked off live trading with five stocks — and lots of Lone Star ambition.

“The Texas Stock Exchange aims to revitalize competition for [stock] issuers, establish the premier venue for listings, and create a world-class trading platform for all market participants,” the exchange says in a fact sheet.

The exchange — whose Texas-influenced nickname is a nod to New York City’s Wall Street — has collected at least $275 million in investments. The roughly 90 financial backers of TXSE include Bank of America, BlackRock, Charles Schwab, Citadel Securities, Dell Family Office, Fortress, Goldman Sachs, and JPMorgan Chase.

Representatives of TXSE couldn’t be reached for comment. On its website, the exchange calls itself “the most well-capitalized equities exchange to ever be approved” by the U.S. Securities and Exchange Commission (SEC).

Not to be outdone, NYSE has launched Dallas-based NYSE Texas and Nasdaq has expanded its presence in Dallas.

Y’all Street adds to Dallas-Fort Worth’s rising status as a major hub for financial services, with The Wall Street Journal naming North Texas the country’s second biggest financial hub after New York City.

“A homegrown national exchange means more jobs, more investment, and more growth opportunities for businesses and communities across the Lone Star State,” Gabriela von zur Muehlen, senior vice president and chief policy officer at the Texas Association of Business, told The Texas Tribune.

Bulent Temel, an associate professor of practice in economics at the University of Texas at San Antonio, told Texas Standard that TXSE “is going to boost the credibility of the Texas economy.”

Texas’ estimated gross domestic product (GDP), a yardstick for the size of an economy, climbed to a record-setting $2.9 trillion in 2025, making it the state with the second highest GDP after California. DFW’s estimated GDP in 2023 stood at $744.6 billion, eclipsing the GDP of many countries.

“The center of gravity for American capitalism is now headquartered in the Boom Belt,” Abbott proclaimed in April, referring to an 11-state region (including Texas) in the South and Southeast that’s seeing tremendous economic and population growth. “The Texas Stock Exchange is the natural extension of that capitalism. It ensures that capital markets will reflect the quadrant that is driving American growth.”

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.

Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.
