Impact Hub Houston — the local chapter of a nonprofit focused on supporting startups in the social impact space — has a lot on its plate this month.

Not only is next week The Houston Innovation Summit — the fourth annual week of entrepreneurship programming — as well as the second annual Climathon, but the organization has also just launched a new business incubator program.

Accelerate is a program that Impact Hub has offered across 17 international markets. Houston's new chapter already has a few Houston startups involved — including Potentia Workforce and McMac CX. Structured as an ongoing accelerator with mentorship, education, and support, the program is currently accepting new members.

"We actually sit down with each new Accelerate member and then go through a diagnostic interview to help them understand what stage they're at," says Grace Rodriquez, CEO and executive director of Houston Impact Hub. "And then we create a development strategy with them."

Whether the Accelerate member needs one-on-one mentorship, specialized education, or more, the program match makes each member's needs. EY is a network partner and — since everything is virtual — member companies have access to international experts through Impact Hub and its partners' networks.

"The ideal entrepreneur for the Accelerate membership is somebody who has already developed a solution — at least an MVP — for their social venture, whether it's a product or a service," Rodriguez says.

She cites Potentia as an example. The startup helps find jobs for adults with special needs, as well as educate corporations on how to work with and collaborate with these individuals. The company already has data and momentum, and the Accelerate program is helping the company to get to it's next stage.

"The idea is that we help people ladder up — no matter what stage you're at," Rodriguez says.

While growing the new program's membership — Rodriguez says it's her goal to get to 10 member companies my early next year — she's also focused on The Houston Innovation Summit and Impact Hub's Climathon.

The second annual Climathon, which begins Friday, November 13, has evolved since last year in a number of ways. First of all, it's completely virtual — which poses its own set of challenges and opportunities. Additionally, the event has several new partners — most of which didn't even exist in Houston last year, like Greentown Houston and Evolve Houston.

One of the biggest, most exciting changes for Rodriguez is the structure. While last year's event functioned as a hackathon, this year attendees can expect thought-provoking programming and collaboration.

"Last year, [Climathon] was directed at people who were more tech savvy," Rodriguez says. "What we found is people who are interested in climate action are a lot of times policy oriented or community activists and they don't know how they can plug into the tech space. It's more of an idea-a-thon. You don't have to develop a tech solution, but we can think about how we can activate more people for climate change."

Last year's Climathon took place during October. WIth it moving to November this year, it coincides with THIS, adding even more events to the week-long, impact-focused summit. THIS, which was designed to run alongside Global Entrepreneurship Week, also considers that week's themes, which are: education, ecosystems, inclusion, and policy.

"The focus on education and policy is really interesting to me — it's not just about tech and business anymore," Rodriguez says. "It's really about how we are supporting businesses in the face of the pandemic, climate change crises — floods, fires, hurricanes — the entire world is being affected by these crises. ... [We need to focus on] how we are making sure that people are aware of everything that's happening and how we can innovate solutions."

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

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.

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