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.

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.

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.

Houston humanoid robotics startup secures millions in pre-seed funding

my robot

A Houston-based startup developing AI-powered humanoid robots for manufacturers and other businesses has raised more than $10 million in pre-seed funding less than a year after its founding.

Nic Radford, co-founder and CEO of Persona AI, declines to disclose the amount raised. However, he tells InnovationMap that it’s between $10 million and $50 million.

While not providing names, Radford says Persona AI’s first outside investors include VC firms, institutions and high-net-worth individuals in the U.S., London and Singapore. One of the high-net-worth investors was among the first employees at SpaceX, Elon Musk’s Brownsville, Texas-based aerospace company, according to Rodford.

No Houston investors have participated in the funding round yet. However, Radford says he’s working on bringing aboard one local investor before the round closes.

“Houston’s the perfect city to do a company like this in,” Radford says. “It’s just not the perfect investor climate, but it's the perfect city from a customer aspect.”

Persona AI’s pre-seed funding comes amid a dramatic surge in investment capital chasing AI startups. Global funding for AI-related companies exceeded $100 billion in 2024, up more than 80 percent from the 2023 total, Crunchbase data shows.

Radford and co-founder Jerry Pratt, the startup’s chief technology officer, bootstrapped Persona AI. The third co-founder, Jide Akinyode, serves as Persona AI’s chief operating officer. Radford and Akinyode helped develop NASA’s six-foot-two-inch Valkyrie humanoid robot and both are former employees of Webster-based Nauticus Robotics, a provider of autonomous subsea robots.

Persona AI launched last June in what Radford calls “anti-stealth mode.” The startup is close to announcing its first customer, which does business in the industrial sector. Persona AI expects customers to take delivery of its first robot in 18 to 24 months, Radford says.

Persona AI will operate primarily as a robotics-as-a-service provider, with the company retaining ownership of the lifelike robots and selling the labor that they supply. Radford says the startup’s robots will help alleviate a shortage of skilled labor in sectors like manufacturing.

A report released last year by consulting firm Deloitte and the Manufacturing Institute declared that as many as 1.9 million manufacturing jobs in the U.S. could go unfilled between 2024 and 2033 due to a skills gap and a tight labor market.

Persona AI competes in a market with enormous potential. In November, analysts at Citi Global Insights projected that the global market for humanoid robots could soar to $7 trillion by 2050, with 650 million of the robots tackling all sorts of jobs.

Radford says Personal AI is developing a “rugged” five-foot-eight-inch humanoid robot that’s able to survive tough indoor and outdoor conditions and take on tasks like carting around sheet metal, tending to metal-stamping machines, moving storage bins and handling order fulfillment. He likens his company’s robot prototype to a Ford F-150 pickup truck, compared to the less-sturdy versions produced by robotics competitors, which he calls the Toyota Camry or Volkswagen Beetles of the field.

Radford says he and his team “are building a really compelling startup in one of the hottest markets and one of the greatest cities.” Employees work at Persona AI’s headquarters in Houston or its satellite office in Pensacola, Florida, where Pratt is located.

“We don’t hire anybody that’s not a rock star or superstar,” says Radford, “and I think the city is going to benefit tremendously from our efforts at Persona.”

Radford saw his last company, Nauticus Robotics, from founding to IPO, left the company in January and previously told InnovationMap that he couldn't get the idea of advancing humanoid robotics out of his head. Read more here.

Blue Origin mimics the moon's gravity for NASA experiments during spaceflight

To The Moon

Jeff Bezos’ rocket company gave NASA a brief taste of the moon’s gravity Tuesday, February 4, without straying too far from home.

Blue Origin launched the 29 lunar technology experiments to the edge of space from West Texas. Plans called for creating a few minutes of artificial lunar gravity by repeatedly spinning the capsule.

It was Blue Origin’s first attempt at mimicking lunar gravity, which is one-sixth that of Earth.

NASA said it wants to test equipment on short spaceflights to weed out any problems before sending them to the moon. The experiments — mainly sponsored by NASA — included ways to keep lunar dust off future moonwalkers’ spacesuits and tools.

Mimicking the moon's gravity on spaceflights can accelerate research at much lower costs and future trips can “closely mirror Mars and other solar system gravity environments,” Blue Origin CEO Dave Limp posted on X ahead of the flight.

The New Shepard rocket landed as planned following the late morning liftoff. The capsule with the experiments parachuted back to the desert to close out the 10-minute flight.

New Shepard alternates between flying passengers and experiments on short space hops. Blue Origin's much bigger orbital rocket, New Glenn, made its debut launch from Cape Canaveral, Florida, last month.
