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.

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

  • 93 percent provide voter registration and/or serve as voting locations
  • 84 percent provide partnerships with local social services agencies
  • 82 percent provide job application assistance
  • 68 percent facilitate applications for government benefits
  • 38 percent provide on-site social services
  • 30 percent provide telehealth rooms and/or resources
"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
