As director of social innovation at Teach For America Houston, it's Sarah Essama's job to come up with new ways for the organization to support both students and teachers. But, as she explains on the Houston Innovators Podcast this week, Essama realized a huge lesson modern students needed was to learn this innovation process themselves.

This line of thinking turned into Essama founding The Dream Lab, powered by Teach for America Houston.

"The Dream Lab is a set of immersive design spaces where young people leverage their imagination and creativity to innovate and solve problems within their community," she explains.

Last month, the new concept rolled out to high school students in partnership with DivInc Houston, a nonprofit focused on social and economic equity in entrepreneurship, and 21 ninth graders spent the day at the Ion for a mini-innovation accelerator and design showcase. Click here to read more.

A Houston-based virtual reality training provider has closed its first round of funding. HTX Labs announced last month that it has received a $3.2 million investment from Cypress Growth Capital.

“We have been looking to secure outside capital to accelerate the growth of our EMPACT platform and customer base but we hadn’t found the right partner who provided an investment vehicle that matched our needs,“ says HTX Labs CEO Scott Schneider in the release. “We found everything we were looking for in Cypress Growth Capital. They have a non-dilutive funding model that aligns with our capital expectations and have the level of experience that really makes this smart money.

The fresh funding will go toward growing and scaling the company's operations — both within the current Department of Defense and expansion opportunities into key commercial markets, like heavy industry, manufacturing, and higher education. Additionally, the funding will support increased customer adoption. Click here to read more.

After months of development and testing, the Houston-born COVID-19 vaccine has gotten the go-ahead to be produced and distributed in Indonesia.

IndoVac was created by the Texas Children’s Hospital Center for Vaccine Development and Baylor College of Medicine. Drs. Peter Hotez and Maria Elena Bottazzi lead the vaccine project. Bio Farma is licensing IndoVac from BCM Ventures, the commercial group at the Baylor College of Medicine.

“Access to vaccines in the developing world is critical to the eradication of this virus,” Hotez, co-director of the Texas Children’s Hospital Center for Vaccine Development and dean of the National School of Tropical Medicine at Baylor College of Medicine, says in a news release.

Houston doctors get approval for low-cost COVID vaccine abroad

green light

A Houston-born COVID-19 vaccine has gotten the go-ahead to be produced and distributed in Indonesia.

PT Bio Farma, which oversees government-owned pharmaceutical manufacturers in Indonesia, says it’s prepared to make 20 million doses of the IndoVac COVID-19 vaccine this year and 100 million doses a year by 2024. This comes after the vaccine received authorization from the Indonesian Food and Drug Authority for emergency use in adults.

With more than 275 million residents, Indonesia is the world’s fourth most populous country.

IndoVac was created by the Texas Children’s Hospital Center for Vaccine Development and Baylor College of Medicine. Drs. Peter Hotez and Maria Elena Bottazzi lead the vaccine project. Bio Farma is licensing IndoVac from BCM Ventures, the commercial group at the Baylor College of Medicine.

“Access to vaccines in the developing world is critical to the eradication of this virus,” Hotez, co-director of the Texas Children’s Hospital Center for Vaccine Development and dean of the National School of Tropical Medicine at Baylor College of Medicine, says in a news release.

Aside from distributing the vaccine in Indonesia, Bio Farma plans to introduce it to various international markets.

“The need for a safe, effective, low-cost vaccine for middle- to low-income countries is central to the world’s fight against the COVID-19 pandemic,” says Bottazzi, co-director of the Texas Children’s Hospital Center for Vaccine Development and associate dean of the National School of Tropical Medicine at Baylor.

“Without widespread inoculation of populations in the developing world, which must include safe, effective booster doses, additional [COVID-19] variants will develop, hindering the progress achieved by currently available vaccines in the United States and other Western countries.”

Bio Farma says it has completed Phase 1 and Phase 2 clinical trials for IndoVac and is wrapping up a Phase 3 trial.

IndoVac is a version of the patent-free, low-cost Corbevax vaccine, developed in Houston and dubbed “The World’s COVID-19 Vaccine.” The vaccine formula can be licensed by a vaccine producer in any low- or middle-income country, which then can take ownership of it, produce it, name it, and work with government officials to distribute it, Hotez told The Texas Tribune in February.

Among donors that have pitched in money for development of the vaccine are the Houston-based MD Anderson and John S. Dunn foundations, the San Antonio-based Kleberg Foundation, and Austin-based Tito’s Vodka.

“During 2022, we hope to partner with the World Health Organization and other United Nations agencies to vaccinate the world. We believe that global vaccine equity is finally at hand and that it is the only thing that can bring the COVID pandemic to an end,” Hotez and Bottazzi wrote in a December 2021 article for Scientific American.

Houston doctors recognized among top creative leaders in business

winners

This week, Fast Company announced its 14th annual list of Most Creative People in Business — and two notable Houstonians made the cut.

Dr. Peter Hotez and his fellow dean of the National School of Tropical Medicine at Baylor College of Medicine, Dr. Maria Elena Bottazzi, were named among the list for “open sourcing a COVID-19 Vaccine for the rest of the world.” The list, which recognizes individuals making a cultural impact via bold achievements in their field, is made up of influential leaders in business.

Hotez and Bottazzi are also co-directors for the Texas Children's Hospital's Center for Vaccine Development -one of the most cutting-edge vaccine development centers in the world. For the past two decades it has acquired an international reputation as a non-profit Product Development Partnership (PDP), advancing vaccines for poverty-related neglected tropical diseases (NTDs) and emerging infectious diseases of pandemic importance. One of their most notable achievements is the development of a vaccine technology leading to CORBEVAX, a traditional, recombinant protein-based COVID-19 vaccine.

"It's an honor to be recognized not only for our team's scientific efforts to develop and test low cost-effective vaccines for global health, but also for innovation in sustainable financing that goes beyond the traditional pharma business model," says Hotez in a statement.

The technology was created and engineered by Texas Children's Center for Vaccine Development specifically to combat the worldwide problem of vaccine access and availability. Biological E Limited (BE) developed, produced and tested CORBEVAX in India where over 60 million children have been vaccinated so far.

Earlier this year, the doctors were nominated for the 2022 Nobel Peace Prize for their research and vaccine development of the vaccine. Its low cost, ease of production and distribution, safety, and acceptance make it well suited for addressing global vaccine inequity.

"We appreciate the recognition of our efforts to begin the long road to 'decolonize' the vaccine development ecosystem and make it more equitable. We hope that CORBEVAX becomes one of a pipeline of new vaccines developed against many neglected and emerging infections that adversely affect global public health," says Bottazzi in the news release from Texas Children's.

Fast Company editors and writers research candidates for the list throughout the year, scouting every business sector, including technology, medicine, engineering, marketing, entertainment, design, and social good. You can see the complete list here

2 Houston doctors nominated for Nobel Peace Prize for low-cost COVID vaccine

major moment

He’s gained national and global acclaim for his battle against COVID-19 and for his efforts, Houston’s Dr. Peter Hotez has been nominated for the 2022 Nobel Peace Prize.

Hotez, and his fellow dean of the National School of Tropical Medicine at Baylor College of Medicine, Dr. Maria Elena Bottazzi, were nominated for the iconic award by Houston Congresswoman Lizzie Fletcher (Texas-07).

The duo, who are also co-directors of the Center for Vaccine Development at Texas Children’s Hospital, were cited in a letter to the Norwegian Nobel Committee for their work to develop and distribute the low-cost Corbevax vaccine to people of the world — without patent limitation.

“My hope is that the nomination not only recognizes the importance of reducing global vaccine inequities and inequalities, but also raises the awareness regarding the importance of vaccines as lifesaving interventions and combating vaccine hesitancy in the US and globally,” Hotez tells CultureMap.

As ABC13 reports, the Nobel nominations were due Monday, January 31. In March, a shortlist is prepared and then reviewed between April and August. The winners are announced in early October and they receive their awards in Oslo, Norway on December 10.

“Dr. Hotez and Dr. Bottazzi’s effort to develop the Corbevax vaccine is truly one of international cooperation and partnership to bring health, security, and peace around the world by creating a COVID-19 vaccine and making it available and accessible to all,” Fletcher said in a statement. “It is a contribution that is of the greatest benefit to humankind.”

Hotez, one of CultureMap’s most-talked-about Houstonians in 2021, added in a statement: “I am honored that Congresswoman Fletcher would nominate us for the Nobel Peace Prize. Dr. Bottazzi and I have worked together for years, and our purpose has never changed — to bring attention to the neglected diseases of poverty and build a new generation of vaccine in the pursuit of global vaccine diplomacy. With our COVID vaccine, which is inexpensive and easy to produce, our intent was to make it available to millions of people in the world who would otherwise not have access to COVID vaccines.”

“When the COVID pandemic hit, we wanted to make a difference and had great confidence our coronavirus vaccine technology, previously developed, could lead to a global solution,” Bottazzi added. “Hopefully, it will be game changing for many countries.”

2 Houston powerhouses deploy game-changing COVID-19 worldwide vaccine

a good shot

With the U.S. logging its highest single-day total of new COVID-19 cases (441,278 infections) and some 281, 808, 270 cases documented worldwide, new treatments worldwide are in major demand — especially in emerging nations.

To that end, Texas Children’s Hospital and Baylor College of Medicine announced a new COVID vaccine ready to deploy in India and soon, other underserved countries.

Corbevax, which is dubbed “The World’s COVID-19 Vaccine,” utilizes a traditional recombinant protein-based technology that will enable production at large scales, per a press release. That means the inoculation will be widely accessible to inoculate the global population.

This new vaccine was developed at Texas Children’s Hospital CVD and led by co-directors Drs. Maria Elena Bottazzi and Peter Hotez — and in-licensed from BCM Ventures, Baylor College of Medicine’s integrated commercialization team, to Hyderabad-based vaccine and pharmaceutical company Biological E. Limited (BE).

After completing two Phase III clinical trials involving more than 3000 subjects the vaccine was found to be safe, well tolerated, and immunogenic. Current research shows Corbevax notably effective against the Ancestral-Wuhan strain and the globally dominant Delta variant, press materials note.

Safe, streamlined, low-cost vaccines for middle- to low-income countries are central to the world’s fight against the COVID-19 pandemic, the two Houston organizations note. Indeed, without widespread vaccination of populations in the Global South, additional virus variants will arise, hindering the progress achieved by currently available vaccines in the United States and other Western countries, per research.

“This announcement is an important first step in vaccinating the world and halting the pandemic,” said Hotez in a statement. “Our vaccine technology offers a path to address an unfolding humanitarian crisis, namely the vulnerability the low- and middle-income countries face against the delta variant. Widespread and global vaccination with our Texas Children’s-Baylor-BE vaccine would also forestall the emergence of new variants. We have previously missed that opportunity for the alpha and delta variant. Now is our chance to prevent a new global wave from what might follow.”

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.
