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.”

As part of the 2026 Houston Innovation Awards, our Deep Tech Business category will honor an innovative startup providing technology solutions based on substantial scientific or engineering challenges, including those in the AI, robotics and space sectors.

Five deep tech companies have been named finalists for the 2026 award.

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

Casimir

Battery tech startup Casimir develops semiconductor chips that produce continuous electrical power straight from the quantum vacuum, without the need for a battery, cord or external charge source. The company is targeting commercialization for its first-generation MicroSparc chip by 2028.

Harold “Sonny” White founded Casimir in 2023 after nearly two decades at NASA. The company emerged from stealth with a $12 million seed round in 2026. It was also awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force earlier this year.

FocisAI

Artificial intelligence startup FocisAI helps refinery owner-operators unlock actionable insights from 3D scans and images.

FocisAI was founded by CEO Tyler Wooten, COO Colin Snell and CTO Kyle Snell in 2026. It is a member of Greentown Labs and launched a seed round in September, which is expected to close by the end of the year, according to the company's application. It has rolled out 10 pilot programs and is looking to move into recurring, facility-scale deployments and scale its team in Houston this year.

Machine Saver Inc.

Industrial tech startup Machine Saver Inc. builds wireless and wired vibration and proximity sensors to tell heavy industry when a machine is about to fail. The company's technology runs on an 8-plus-year battery life and helps operators reduce downtime, improve maintenance and extend equipment life.

Machine Saver was founded by CEO Colton Bach and Quentin Bach in 2013. Its customers and partners include Houston Methodist, Blue Bell, Genemco, as well as energy and heavy industry, food and beverage, and cold chain companies, according to its application. The company is raising a Series A.

It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
