Dr. Joseph Rogers, the president and CEO of the Texas Heart Institute, is passionate about preventative health care for THI and its patients, as he shares on the Houston Innovators Podcast. What's required is a comprehensive culture shift away from just using a pill to accomplish this goal.

Rogers says health care organizations are going to need to partner with other players — nonprofits, universities, local government — in ways never been done before. And THI is dedicated to this mission.

"Houston is the place to do this," he says. "The reason I think this is such an important community to address this problem is it's the most diverse city in the United States. And I've never lived anywhere or heard of another city that I was so convinced believed they could do anything they set their minds to. It's about making the community aware of the problem and a potential solution — and then working on trying to solve it." Read more.

San Diego, California-based Ascent, a collegiate student loan company that also provides student support services, announced it has acquired Houston-based Ampersand, a software platform that provides skills training to young professionals.

With the acquisition, Allie Danziger, co-founder and CEO of Ampersand, joins Ascent as senior vice president and general manager of student success. She will lead the company's educational program that focuses on equipping students with skills from education to employment.

“Since launching Ampersand in 2020, we’ve received constant praise from employers, students, and universities on the real education-to-employment skills gap we are filling,” says Danziger in a news release. “I take immense pride in the fact that we’ve helped thousands of students enter the workforce with confidence, earn higher salaries, and get set on the right career path. I know joining the Ascent team will unlock even more opportunities for our combined companies, expanding our collective impact to millions of students and job seekers.” Read more.

Innovative Houston nonprofit taps into biotech to preserve ecological biodiversity

For centuries, humans have been negatively impacting the natural world around them. A Houston organization is looking to leave an impact on the environment — but this time for the better.

Based in Houston, RioRaiz is a 501c3 nonprofit organization charting a unique course in the world of conservation and education. Founded in March of 2021, RioRaiz – meaning "root of the river" in Spanish, a nod to its deep-rooted connection with South American culture – seeks to preserve biodiversity through biotechnology and offer transformative learning experiences to contribute to a healthier planet.

Led by Jeff Carlson, the president and CEO, RioRaiz's mission is driven by three core pillars: conservation, scientific discovery, and education.

Currently, the nonprofit's efforts are focused on regions on the edge of ecological disruption, specifically the East Texas area and the Tropical Andes. In Texas, the organization aims to expand the biome of the Big Thicket National Preserve in Kountze as well as engaging locals by hosting clean-up drives. In the Andes, RioRaiz aspires to establish biological corridors between national parks and natural reserves, diminishing potential disruptions to animal migration patterns.

The timeline for these critical initiatives, Carlson said, hinges on donations.

"We have a list of priorities that is cataloged from input from our scientific collaborators, as well as our ability to deliver on our promises to our donors and supporters,” Carlson said.

Partnerships form a critical role in RioRaiz's work, notably those with academic institutions in the United States and Colombia. One of these collaborations saw Carlson spend three months in Colombia, working with the local Páez tribe, also known as the Nasa, to explore the potential of their traditional medicines for modern treatments.

"We're really excited to learn and to share our techniques and our knowledge," Carlson said, underlining the organization's commitment to partnering with traditional and indigenous knowledge sources.

With its blend of biotechnology, conservation, and education, RioRaiz seeks to inspire a new generation of conservationists. By offering an intimate virtual glimpse into the world's biomes, the nonprofit aims to instill a deep-rooted respect for nature and encourage sustainable action.

"If you expose students to these different kinds of environments at an early age, that might inspire somebody to go into conservation," Carlson said.

With a progressive effort, RioRaiz is harnessing the power of virtual reality to redefine education. The organization uses specialized filming equipment during its expeditions, capturing moments like the discovery of new species or conducting bio surveys. RioRaiz's visually compelling stories will surpass language barriers, transporting students virtually to different biomes. In time, Carlson hopes to distribute pre-loaded systems to communities with limited internet access, taking the classroom to every corner of the world. These virtual reality experiences are expected to launch within the next year.

"We want to bring the rainforest into the classroom," Carlson said.

Through its work, RioRaiz aims to demonstrate that the route to a sustainable future lies not just in face-to-face interactions, but in a global, interconnected approach to education and conservation. Its vision is clear — to grow far beyond traditional reaches, preserving biodiversity and fostering a healthier world.

Why building bridges in Houston's nonprofit, innovation communities should be a priority

guest column

I have witnessed numerous Houston-based nonprofits utilize the enormous advantages of community involvement in catalyzing creativity and creating real, sustainable change, but nonprofits can't accomplish everything on our own. For-profit organizations, private academic institutions, and government entities have a substantial role to play in growing community projects, embracing connections, and bolstering nonprofit efforts. Let’s explore some of the advantages of for-profit businesses partnering with nonprofits in order to grow all-around community innovation development.

Connecting with local communities

A vital first step in promoting community participation for innovation is connecting with local communities. For-profit companies can participate in regional projects, pay attention to local residents, and comprehend the opportunities and issues facing their areas. This can assist them in creating strategies that are adapted to local requirements and have a significant impact.

Collaborating with organizations

To spur innovation and realize common objectives, collaboration is essential. For-profit businesses can cooperate with nonprofit groups that share their goals and ideals. This may result in a situation where everyone gains from the collaboration. Non-profit groups can provide their local experience, passion, and connections to the community, while for-profit businesses can contribute their resources, networks, and specializations.

Offering volunteer incentive programs and opportunities

For-profit businesses can engage their staff members and encourage them to participate in community projects by providing volunteer incentive programs and opportunities. This can improve job satisfaction, boost staff morale, and foster a supportive business culture. Additionally, volunteering can benefit workers by allowing them to grow their networks, learn new things, and obtain new experiences.

Engaging in educational initiatives

Another successful strategy for for-profit businesses to encourage community participation for innovation is to participate in educational projects. For instance, they can collaborate with educational institutions to support STEAM (science, technology, engineering, art, and mathematics) initiatives. A pipeline of smart young professionals who are enthusiastic about innovation and social impact may result from this.

Being willing and open to put themselves out there

Lastly, but perhaps most importantly, for-profit businesses must be open and take the potential risks in order to engage with communities and create the seeds of innovation. Businesses open to new concepts and methods, listening to criticism, and conducting transparency can produce happier employees by incorporating the same practices they use to build community engagement. For-profit businesses can truly benefit their own profitability by being willing to cultivate long-lasting relationships and meaningful projects with nonprofits: all while having a significant impact on their communities.

Ultimately, by emphasizing community involvement and engagement organizations can stimulate creativity, attain common objectives, and make social impact, benefiting private, public, nonprofit, for profit, and government agencies alike.

Building bridges, cooperating with nonprofit groups, and supporting community initiatives are all important roles for for-profit businesses to play. For-profit businesses can encourage general community engagement for innovation and change the world by interacting with local communities, working with nonprofits, providing volunteer incentive programs and opportunities, taking part in educational initiatives, and being open and willing to put themselves out there.

5 Houston deep tech startups pushing the boundaries of their industries

meet the finalists

Houston has long been at the forefront of innovation, from NASA’s Johnson Space Center to its startup ecosystem using technology to disrupt industries.

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.
