Sarah "Sassie" Duggleby and her husband were living in Japan and considering a trip back to Texas and wishing there was a faster option than a full day of international travel — with their kids, no less. That's when Andrew Duggleby told Sassie that there actually might be an engine that could do that.

Flash forward a few years, and the husband-wife team has built a company around that idea. Venus Aerospace, originally founded in California, relocated to Houston in 2021 to establish their company in an ecosystem with the tools to advance their tech — and give their employees a good work-life balance, Sassie Duggleby explains on the Houston Innovators Podcast.

"We knew we had to find a location where we could test our engine and still be home for dinner," she says on the show. "Our company vision is 'home for dinner.' We want to fly you across the globe and have you home for dinner. And, if you work for us, we want you home for dinner." Read more.

Youngro Lee is no stranger to shaking up the finance world with a new tech-based way of doing business. One of the founders of NextSeed, Lee's newest mission is providing "investment infrastructure as a service" with his company, Brassica, which just raised $8 million in seed funding.

“The future of finance will depend on the ability of trustworthy institutions to provide secure and seamless transitions between traditional financial services and web3 innovations while complying with strict regulations and still providing great customer experience,” says Lee in the news release.

Houston-based Mercury Fund led the round with several other investors participating. Read more.

Le Dam, CEO and founder of OptiChroniX

After years on the West Coast, Le Dam has returned to her adopted hometown of Houston — just in time to launch a new app dedicated to providing health resources and information to its users.

“I always knew that I wanted to build my business in Houston,” Dam says, mentioning the assets of the world’s largest medical center, a thriving startup community, and diverse population for whom she wants to build her technology.

myAvos pairs with a user’s smart watch and harnesses their health information such as physical activity and hours slept. The user can also input additional information such as blood test results and meals eaten. The app analyzes the information provided and assesses the user’s risk for chronic illness later in life.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries — from 3D printing to food and cooking — recently making headlines in Houston innovation.

Alessio Lorusso, founder and CEO of Roboze

The hit the pandemic has had on the global supply chain has been a huge hit to so many companies. However, one Italian company with its United States headquarters in Houston, has an alternative for customers — large scale, in-house production. Roboze, which recently completed a multimillion-dollar fundraise, has seen explosive growth due in large part to how COVID-19 has affected the global supply chain over this past two years.

"This was an incredible accelerator for us," says Alessio Lorusso, CEO and founder, on the Houston Innovators Podcast. He adds that, while Roboze has attracted large corporate customers, the business is seeing growth in the small to mid-sized company sector.

"The moment is now," Lorusso says. "The time to integrate printing capabilities and have the possibility to print parts in house is something that needs to be done now." Click here to read more and listen to the podcast.

Tobi Smith, founder of All I Do Is Cook

Tobi Smith wanted to take his business to the next level — and he found the perfect opportunity to do so. After completing the gBETA accelerator program and winning the grand prize in the ClearCo ClearPitch competition, Smith and his business partner Bethany Oyefeso are transitioning their small business, All I Do Is Cook, into a startup with the ultimate goal of making Nigerian food accessible to everybody.

Smith and Oyefeso came one step closer to that goal when Phoencia, a Houston grocery story, started stocking the startup's condiments in 2021. In that same year, Smith and Oyefesso joined the gBETA accelerator program. Smith described this program as being instrumental in the advancement of their company from a small business to a start up, now at the beginning of their pre-seed funding phase.

“They taught us everything about what it meant to be a start up and connected us with mentors and other individuals working in the food and beverage space,” says Smith. Click here to read more.

Pradeep Sharma, engineering department chair at the University of Houston

The National Academy of Engineering elected its new members, and five local scientists are among the new 133-person cohort — as is Elon Musk, if you were wondering. The appointment is among the highest professional distinctions in an engineer's career.

Pradeep Sharma, M.D. Anderson Chair Professor and department chair, Department of Mechanical Engineering, University of Houston, was recognized for establishing the field of flexoelectricity, leading to the creation of novel materials and devices and insights in biophysical phenomena.

“Nature has provided us very few piezoelectric materials even though their applications in energy harvesting and in making sensors is very important. What we did was use theory to design materials that perform like piezoelectric ones, so that they can create electricity,” says Sharma in the release. Click here to read more.

3 Houston innovators to know this week

Who's who

It seems like 2020 is the year of the pivot and taking what the world has thrown at you —from pandemics to oil gluts — and making something out of what you have.

This week's innovators to know include a Houston startup flipping the switch on production to make face masks to the Rice Alliance re-envisioning an annual event that usually takes place at a global conference.

When Megan Eddings and Amanda Cotler saw the CDC was recommending medical professionals wear bandanas or strips of cloth when surgical face masks weren't available, they had an idea.

The duo behind Accel Lifestyle, a Houston-based athletic wear startup that has a bacteria-resistent fabric, hopped on a call to see how they could rework their supply chain to quickly pivot to making face masks.

When setting up the company, Eddings, Accel's founder, made it a priority to avoid sweatshops, and she set up her supply chain to be completely within the United States — something that's been beneficial to the company's COVID pivot.

"If we did not have a 100 percent domestic supply chain, there's no way we could have done this," Eddings says.

Eddings and Cotler joined the Houston Innovators Podcast to share the story of how Accel went from deciding to make the masks to selling them by the thousands to Houston Methodist.

"When you think of face masks, you wouldn't think about activewear or thinking of Accel being a part of the fight against coronavirus," Cotler says. However, that might no longer be the case for the company now. Click here to learn more and to stream the podcast episode.

Rice Alliance for Technology and Entrepreneurship typically hosts their Energy Tech Venture Day from the one of the halls within NRG Arena at the annual Offshore Technology Conference. However, the conference that attracts thousands of people from around the world, much like so many events, was canceled due to coronavirus.

But Brad Burke and his team at the Rice Alliance turned to tech to introduce the first virtual event, which then took place on Thursday, May 7. Burke introduced the event that had 39 startups that represented 11 different states and six different countries, 13 call Houston their HQ.

"We had many startups and corporations reach out to us and ask us if we could go ahead with the event in a virtual format, so that's how we ended up where we are today," says Burke. Click here to read more.

3 Houston innovators to know this week

who's who

While headlines about coronavirus keep multiplying — similar to the virus' cases, Houston's innovation news hasn't yet slowed.

This week's people to know include a female entrepreneur who's leveling the playing field for outdoorsy women, a blockchain expert with new growth, and an investor creating the angel network she's been wanting for years.

Debbie Mercer, founder of Zip Hers

Debbie Mercer, a Houston entrepreneur, has designed articles of clothing to empower female athletes. The marathon runner was tired of seeing female runners standing in long lines, awaiting their turns to do their business behind closed doors, while their male friends resorted to quickly and discreetly ducking behind the porta-potties, or finding nearby trees. Precious time ticked by as the women watched their male counterparts continue the race.

The Houstonian created Zip Hers, an activewear brand that has a full-length zipper lining the bikini area of each pant, to accommodate on-the-go women. The Zip Hers concept and design was intended to level the playing field for women and men when it comes to competitive sports.

"If we're wasting time on a bathroom break and they're not, that holds us back…Maybe it's our little tiny contribution to women's equality. We just really want to help women be the best that they can be," Mercer says. Click here to read more.

Andrew Bruce, CEO and founder of Data Gumbo Corp.

For the fist time, Data Gumbo Corp.'s GumboNet will be used in geothermal energy drilling thanks to the startup's new Indonesia-based client, Air Drilling Associates, a drilling and project management service provider.

"Expansion into Southeast Asia with ADA's deployment signals GumboNet's global applicability and benefit to industry — in this case, geothermal energy development," says Andrew Bruce, CEO and founder of Data Gumbo, in a news release. "We are excited that Data Gumbo is entering yet another sector of the energy market for improvements across its supply chain." Click here to read more.

Maria Maso, founder of Business Angel Minority Association

Maria Maso, frustrated with her investment opportunities in Houston, has launched the Business Angel Minority Association, or baMa, to gather established or brand new angel investors to move the needle on investments into minority-founded startups. Maso, founder and CEO, and Garaizar, president, want to round up 100 investors by the end of 2020. And they want these investors to write checks.

"We are not a networking organization. We are an investment organization. We are expecting at some point that you are writing a check to a startup," Maso says. "If we are doing our job properly and we are showing you the right startups, you should be able to make a check at some point." Click here to read more.

After 20 years in the venture capital world, Sandy Guitar Wallis has seen the evolution of investing — on both coasts and here in Houston as well. Now, as managing director of the HX Venture Fund, Wallis leads the fund of funds that's investing in VCs around the country in order to bring investment to Houston.

"We have raised a fund of funds with the HX Venture Fund, and we're deploying that capital across probably 10 venture capital funds over time," Wallis explains on the most recent episode of the Houston Innovators Podcast. "Each one of those funds, will invest in 15 to 20 underlying private companies. So, at the end of the day, HX Venture Fund 1 will have exposure to 10 VC funds, as an example, and — by virtue of those investments — maybe 300 private companies." Click here to read more.

Startups fail — and there are a number of reasons why that is. James Y. Lancaster, who serves as Texas branch manager for Arkansas-based VIC Technology Venture Development, writes in a guest column for InnovationMap about the second most common reason for startup failure: funding.

"A key part of the startup CEO's job is to understand how much total cash remains on hand and whether it is enough to carry the startup towards a milestone that can lead to successful financing as well as a positive cash flow," Lancaster writes. "Just as important is how to allocate their time and efforts to the fundraising process along the way." Click here to read more.

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.

Square Robot

Energytech startup Square Robot develops and operates submersible inspection robotics that inspect aboveground storage tanks while they remain in service. The robots reduce downtime and costs, improve worker safety and limit hydrocarbon emissions.

Square Robot launched its Houston office in 2019 and closed a Series B in 2025. It plans to complete its first U.S. Navy demonstrator tank in November and is also developing real-time inspection software.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines.

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.
