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.

Houston innovator launches holistic health and cognitive care app

Meet Laura. She’s not human, but she could be the key to your aging healthfully. She’s the digital wellness coach on myAvos, a groundbreaking app that launched this week from OptiChroniX.

Now meet Le Dam, the woman behind the app. Dam is a medical doctor, as well as CEO and co-founder of OptiChroniX. While practicing medicine in her birthplace of Australia, Dam realized that her life of prescribing medications to patients who were already sick was not how she had envisioned helping people. She knew that prevention, using the five pillars of healthy aging — nutrition, activity, sleep, health, and stress — was the way to keep patients fit and happy into their golden years.

She returned to California, where she lived after leaving Houston as a youth, to work at a startup with the goal of one day heading a company of her own. She met Swiss-based COO and co-founder, Rene Gilvert, on LinkedIn.

“He was looking for a medical doctor to join his startup,” Dam recalls. “We were so well aligned that we decided to join forces.” Now, the team works remotely in locations ranging from Dam’s home in Houston to Portugal.

When the pandemic happened, Dam took the opportunity to leave the Silicon Valley and work remotely from Houston, a return that she says was always her end goal.

“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. From there, Laura coaches them on what changes they can make to live healthier lifestyles. The app even reminds users when to take their medications and shares information with designated caregivers.

The app has been designed by behavioral health scientists to understand why you’re not exercising enough or eating right and can offer personalized motivations to get users off the couch.

Right now, the focus is on potential dementia and cognitive impairment, says Dam, but in the future, myAvos will more holistically target all preventable chronic illnesses. But dementia is one of the major causes of disability among older people around the world and people living with it is expected to triple by 2050.

“If we can empower people with health literacy, we really believe we can prevent chronic disease,” says Dam. “Forty percent of dementia is preventable. A lot of these chronic diseases are preventable. Even diabetes can be reversible.”

And she points out that the changes that can be made to help cognitive health can affect other systems as well.

“We really want to empower the individuals,” Dam says. “If we can empower people with health literacy, we really believe we can prevent chronic disease.”

And myAvos is the key. The app is based on a subscription model, allowing users full access to a risk calculator, monthly cognitive assessments, personalized lifestyle guidance, and even fun brain games to keep them sharp. It may turn out that a visit with Laura a day will keep the doctor away long into your later years.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
