Coya Therapeutics has named a new CEO. As of Nov. 1, Arun Swaminathan replaced Co-founder Howard Berman in the role. Berman has assumed the title of executive chairman, in which he will still remain active with the company.

Swaminathan started with Coya two years ago as chief business officer. This transition was planned, says the PhD-holding scientist and businessman.

“(Berman's) intent was that it was the right time to put in place a CEO that, as we move into the operational phases of the company, that can take the reins from him,” he tells InnovationMap.

Coya Therapeutics is a publicly traded biotechnology company that is working on two novel treatments for Alzheimer's disease. Coya's therapeutics, which are currently in trials, use regulatory T cells (T regs) to target both systemic- and neuroinflammation in patients.

InnovationMap: Berman has been a very visible CEO. Will you follow suit?

Arun Swaminathan: I think it's part of the CEO’s job to be visible and to communicate the value of our company to all the stakeholders out there. So yes, I do plan to be visible as well. Obviously, Howard as the founder had elements that he talked about, the foundational stories. I obviously will be doing less of that.

IM: What was your journey from the lab to the boardroom?

AS: I have a PhD from the University of Pittsburgh. I like to say that I grew up at Bristol Myers Squibb, so I started in a clinical pharmacology group at BMS, running clinical trials, but in the cardiovascular and metabolic space.

What happened was, as I was the study director on a diabetes trial there, and the data starts coming in for these early diabetic trials, and I got highly involved with the commercial folks at BMS in starting to plan out “What does the target profile look like? How is this going to play out in the real world?” You know, the marketing teams and commercial teams start engaging when clinical data is available, because they're starting to plan for the eventual launch of the product.

That gave me a lot of exposure to the commercial side of things, and I also got a lot of experience presenting to opinion leaders and others through that role. And I said, “What I really love is that intersection between science and business.” And so I think that was my moment.

Then I moved to business development and licensing, where I helped scan the universe for assets and talk to CEOs of companies like Coya as a junior person, trying to understand if there's something that we can bring into BMS to strengthen the pipeline of BMS. So that gave me exposure to deals, how deals are structured, how you negotiate a lot of that kind of stuff.

Then I said, “Look, if I want to be a complete person in biotech, I do need to go into more true commercial roles.” So I went into commercial strategy. I was involved in the commercial strategy for what is now known as Eliquis. Was back then known as apixaban. That’s still the generic name.

Then I led marketing for Orencia, a rheumatoid arthritis drug. So I went and got both strategic and tactical marketing experience at BMS, and then I used all of that experience, rounded up. I eventually ended up co-founding a company, and that's led me to the last nine years with smaller biotech companies. So that's my evolution and path. But I think my true moment of realization was about three years into my clinical role at BMS, when I said, what I really enjoy is translating good science into commercial value, and I think that's what excites me.

IM: Why is Houston an important part of Coya's success?

AS: It is important that Coya stays in Houston, because we have a very close association with Houston Methodist, we get a lot of our work, our early research work still done through Houston Methodist, through Dr. [Stanley] Appel's lab and through other experts. We absolutely have a special research agreement with Houston Methodist, so we have a very strong reason to be in Houston. So, we do not anticipate moving out of Houston.

Houston company with revolutionary neurodegenerative disease treatment shares milestones since IPO

ring that bell

After announcing its initial public offering earlier this year, a Houston therapeutics company has celebrated the milestone and announced recent growth as well.

Coya Therapeutics (Nasdaq: COYA) rang the closing bell last week. The clinical-stage biotech company, which has developed a biologics therapy that prevents further spreading of neurodegenerative diseases by making regulatory T cells functional again, announced the closing of its $15.25 million IPO in January.

"We launched our IPO into one of the toughest biotech capital markets in recent memory and are enormously grateful to all our investors for the confidence they then showed in our prospects," says Howard Berman, CEO and chairman of Coya, in a June 12 letter to stockholders. "I believe that to date, we’ve executed strongly against the goals we then established, and I remain excited about our future."

In the letter, Berman shares some of the recent clinical successes from two treatments — COYA 302, a treatment for ALS, and COYA 301, a treatment for Alzheimer’s Disease. Both treatments have seen strong clinical proof of concept data in the respective open-label studies.

Earlier this year, Coya expanded its C-suite to include Dr. Arun Swaminathan as chief business officer. He has over 20 years of hands-on health care business executive experience. Prior to Coya, Swaminathan served in the same role for Actinium Pharmaceuticals.

"Arun is actively engaged in exploring potential strategic opportunities across our portfolio of assets as we believe successful partnering efforts have the potential to enhance our scientific bona fides, leverage our technology into new areas of unmet medical need, and importantly, possibly secure upfront fees and associated non-dilutive funding," Berman writes in the letter. "We look forward to pursuing additional value creation catalysts that further highlight our entrepreneurialism and ability to execute, while maintaining focus on our core assets."

The latest addition to the Coya team is Guillaume Dorothée, who joins the company's scientific advisory board. A leading expert on the role that the immune system and peripheral-central immune crosstalk play in the pathophysiology of Alzheimer's, he's a tenured research director and team head in neuroimmunology at the French National Institute of Health and Medical Research in Paris.

“I am glad and honored to join such eminent scientists on the prestigious SAB of Coya Therapeutics," he says in a June 5 statement from Coya. "I am fully convinced that innovative Treg-based immunomodulatory approaches, as developed by Coya, are highly promising therapeutic strategies for the treatment of neurodegenerative disorders and other neuroinflammatory conditions. I will be happy to help Coya Therapeutics in this exciting endeavor.”

Recently, Berman joined the Houston Innovators Podcast to discuss Coya's mission and plan post IPO.

Why this Houston innovator is racing to commercialize its unique treatment for neurodegenerative diseases

HOUSTON INNOVATORS PODCAST EPISODE 182

When Howard Berman sought out renowned Houston Methodist researcher and neurologist Dr. Stanley Appel, he was looking for treatment for his father, who was suffering from dementia. He wasn't looking for a job, but Dr. Appel had other ideas and asked Berman to meet with him.

"I was interested in what I could do for my dad," Berman says on the Houston Innovators Podcast, explaining how he took the meeting with Dr. Appel, who then presented him with some of his research. "By slide five my jaw had hit the ground.

"He had shown that he could stop the progression in one of his early trials of ALS," Berman says.

Not too long after that meeting, Berman, who founded digital health platform imaware, joined Dr. Appel to lead commercialization of Coya Therapeutics, a biotech startup that raised over $20 million in venture funding before going public a few months ago.

Coya has developed a biologics therapy that prevents further spreading of neurodegenerative diseases by making regulatory T cells functional again. Diseases like ALS, the company's focus right now, prevent T-regs from doing their job in controlling inflammation, and without these cells hard at work, the human body doesn't stand a chance in fighting autoimmune threats.

Berman, as co-founder and CEO, has been at the helm of the company leading it through both the fundraising and IPO processes. Coya's IPO occured in a tough market — only 12 biotech companies went public last year, he explains. To Berman, that just proves how passionate the team was about getting this product to those who need it.

"It really says something for the fortitude and our team to come together to make it happen," he says on the show. "We're able to deliver and execute in a difficult market climate.

"Once you're a public company, you have different expectations," he continues. "But you also have the opportunity to go out and attract additional investors in ways you can't do as a private company."

For Berman, whose father passed away earlier this year, it's a personal motivation that drives him to lead the company — as well as an opportunity to advance the city of Houston.

"The next number of years as we develop this therapeutic regimen for ALS, we have the potential to transform Houston into something more than it is currently," he says. "Our success will be the city's success."

Berman shares more of the Coya Therapeutics story on the podcast, as well as how he sees Houston's potential as an emerging hub for biotech. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
