Houston startup scores on TV, medical entrepreneurs land new gigs, and more innovation news

short stories

It's been a busy month so far with plenty of Houston startup news, new hires, and more — and there might be some headlines you may have missed.

In this roundup of short stories within Houston startups and tech, a startup snags investment from two sharks, two medical professionals take on new roles, and more.

Milkify lures in two sharks on TV debut

Milkify, a Houston startup that's created a breastmilk freeze-drying business, appeared on ABC's Shark Tank on April 7 and got two investors to bite. Gwyneth Paltrow and Lori Greiner agreed to a $400,000 convertible note for 20 percent equity in the company.

“It’s a dream team — Lori and Gwyneth — to help us grow this company and help us take it and make it more available to moms," says Berkley Luck, COO and co-founder, on the show.

Luck founded the company with her husband, Pedro Silva, and told InnovationMap the company has freeze-dried and powdered more than half a million ounces of breast milk since founding in 2019.

On the show, the duo explained that some of the customers' employers paid for the process.

“It gives such agency to working moms, it empowers them,” Paltrow says on the show. “I work at a company with so many women and nursing mothers. Breastfeeding really factors in for women. This makes working less of a guilty experience for mothers.”

Coya Therapeutics, a clinical-stage biotechnology company with multiple therapeutic platforms, announced Arun Swaminathan will be taking on the role of chief business officer. He will be responsible for new business development partnerships, including licensing opportunities, across the company. Swaminathan has over 20 years of hands-on health care business executive experience.

“Our team is excited to welcome Arun to Coya at such an exciting time in our evolution. We look forward to working with him as we leverage his extensive experience and successful track record in corporate strategy and business development,” says Howard H. Berman, CEO of Coya, in a news release. “This is an opportune time for Arun to join our team on the heels of recent positive data and as we accelerate the clinical development of our biologic and cell therapy Treg immunomodulatory assets. We are confident that Arun’s contributions will prove to be impactful for Coya and our shareholders.”

Prior to Coya, Swaminathan served in the same role for Actinium Pharmaceuticals.

“Coya has an innovative pipeline, and its multiple therapeutic platforms provide a strong base for potential value-creating partnerships,” says Swaminathan in the release. “I look forward to working with Howard and the Coya team to realize the promise of Coya’s portfolio and deliver new therapies for patients.”

A Houston company that is retrofitting commercial buildings for energy efficiency has joined a brand new Maryland-based accelerator. INOVUES has been named to the Montgomery County Economic Development Corp.'s inaugural cohort for its Hospitality Tech Accelerator.

The six selected companies are focusing on some of the hospitality industry’s top sustainability challenges, according to a news release, including energy, water, and waste reduction and management. The cohort will be supported by experts in the sustainability, travel, foodservice, and hospitality industries from Growth Advisors International Network and Bethesda Green’s Innovation Lab mentor network, per the release.

“We were particularly impressed by the caliber of applicants for this inaugural program,” says Bill Tompkins, president and CEO of MCEDC, in a statement. “The selected companies have developed innovative solutions that can be implemented today to reduce food and material waste, detect water loss, and provide fast and convenient energy savings through high-performance insulation, AI and machine learning, and smart glass retrofits."

In a recent interview with InnovationMap, founder Anas Al Kassas says commercial building energy efficiency is a major contributor to energy consumption.

“If you look at buildings today, they are the largest energy-consuming sector — more than industrial and more than transportation,” Kassas said in December. “They account for up to 40 percent of energy consumption and carbon emissions.”

Female Houston founder on her dream of making high-speed, international travel a reality

HOUSTON INNOVATORS PODCAST EPISODE 181

Sarah "Sassie" Duggleby is on a mission to get people home in time for dinner — whether they are traveling around the world or working for her business. That's why she founded Venus Aerospace, which is developing hypersonic space planes. It's also why she relocated the company from the West Coast to Houston.

"We knew we had to find a location where we could test our engine and still be home for dinner," Duggleby says on this week's episode of the Houston Innovators Podcast. "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."

Venus's technology enables this revolutionary travel through its supersonic combustion engine — more akin to a rocket's engine than an airplane's — that allows for travel at a higher elevation, she explains on the show. Jet engines rely on air outside of the aircraft to combust, and rocket engines work with a system that supplies air internally. And, as Duggleby explains, the engine can go further with the same amount of fuel, so it's a more sustainable way of traveling too.

"Our ultimate goal is to go with completely carbon-free propellants. There are fuel choices we could make that would be carbon free, but the biggest challenge is continuous operability," she says, explaining that there would then need to be green fuels at whatever airport Venus aircrafts land in to refuel. "You've got to stand up an entirely green ecosystem across the globe. But I think the world would handle that."

The company's developed engine right now works with jet fuel and hydrogen peroxide, a source that can be made without any carbon emissions, she says.

Duggleby founded Venus Aerospace with her husband and CTO Andrew in 2020. The two worked for Virgin Orbit before leaving to start Venus, relocating to Houston in 2021 and setting up shop in a hangar at Ellington Field in the Houston Spaceport. Last year, Venus raised a $20 million series A round.

Once a scrappy team of three people, Venus Aerospace now has almost 100 employees. When thinking about the challenges she's facing, Duggleby says she knows how to navigate the engineering journey the technology faces and she knows they face regulatory obstacles ahead too. Something Duggleby, recently named to Inc. magazine's Female Founders list, is focused on these days — with the pace of growth at the company — is staying true to the company culture she founded since day one.

"There's a constant tension to grow, grow, grow, and build out bigger systems, versus take what you have now and get it really great," she says on the show, recognizing that aerospace work environments tend to have more toxic and competitive cultures. "As important as the technology that we're building is, it's also just as important who we are and how we treat our people."

Duggleby shares more of her story on the podcast, as well as her observations on the space tech industry, Houston's role in the ecosystem, and more. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

3 Houston companies rank among best in biz list

better than all the rest

In the season’s spirit of giving, Inc. magazine has named three Houston companies to its 2022 Best in Business list, recognizing companies that put purpose before profit.

The Houston honorees are:

Enchanted Rock, a producer of energy microgrids powered by natural gas and renewable natural gas. In a news release, Thomas McAndrew, the company’s founder and CEO, says the Inc. recognition reflects “the dedication and hard work of our employees who work tirelessly to help our customers keep their power on.”
Proxima Clinical Research, a contract research organization for the biotech and medtech sectors. Earlier this year, Proxima appeared on the Inc. 5000 list of the country’s fastest-growing private companies.
Smith, a distributor of electronic components and semiconductors. The company has undertaken several humanitarian relief efforts for Ukraine, including the donation of at least $750,000 worth of electronics to Ukrainian citizens.

Inc. says its Best in Business list recognizes “the most dynamic companies of all sizes and industries that have had an outstanding influence on their communities, their industries, the environment, or society as a whole.”

Rather than relying on criteria tied to sales or funding, Inc.’s editors reviewed companies’ achievements over the past year and focused on how they made a positive difference in the world. They then selected honorees in 55 overall categories, and in age-based, revenue-based, size-based, and impact-based categories.

In all, Inc. named 14 Texas companies to this year’s Best in Business list. Aside from the three Houston companies, they are:

Austin-based AlertMedia, which produces emergency communication software
Austin-based Halcyon, a provider of security technology
Austin-based Matterlab, a communications agency
Austin-based Pushnami, which offers an advertising and engagement platform
Austin-based ZenBusiness, a provider of business products and services
Dallas-based Upkeep Aesthetics, a franchiser of medical spas
Fort Worth-based TimelyMD, which delivers virtual health and well-being services for students
Frisco-based Lexipol, a provider of policy, training, and wellness services for the public safety sector
Irving-based Tricolor Holdings, which sells used cars and extends auto loans to underserved Hispanic consumers
Plano-based Improving, a provider of tech consulting and training
San Antonio-based AmeriVet Veterinary Partners, an operator of veterinary practices

Houston-area lab grows with focus on mobile diagnostics and predictive medicine

mobile medicine

When it comes to healthcare, access can be a matter of life and death. And for patients in skilled nursing facilities, assisted living or even their own homes, the ability to get timely diagnostic testing is not just a convenience, it’s a necessity.

That’s the problem Principle Health Systems (PHS) set out to solve.

Founded in 2016 in Clear Lake, Texas, PHS began as a conventional laboratory but quickly pivoted to mobile diagnostics, offering everything from core blood work and genetic testing to advanced imaging like ultrasounds, echocardiograms, and X-rays.

“We were approached by a group in a local skilled nursing facility to provide services, and we determined pretty quickly there was a massive need in this area,” says James Dieter, founder, chairman and CEO of PHS. “Turnaround time is imperative. These facilities have an incredibly sick population, and of course, they lack mobility to get the care that they need.”

What makes PHS unique is not only what they do, but where they do it. While they operate one of the largest labs serving skilled nursing facilities in the state, their mobile teams go wherever patients are, whether that’s a nursing home, a private residence or even a correctional facility.

Diagnostics, Dieter says, are at the heart of medical decision-making.

“Seventy to 80 percent of all medical decisions are made from diagnostic results in lab and imaging,” he says. “The diagnostic drives the doctor’s or the provider’s next move. When we recognized a massive slowdown in lab results, we had to innovate to do it faster.”

Innovation at PHS isn’t just about speed; it’s about accessibility and precision.

Chris Light, COO, explains: “For stat testing, we use bedside point-of-care instruments. Our phlebotomists take those into the facilities, test at the bedside, and get results within minutes, rather than waiting days for results to come back from a core lab.”

Scaling a mobile operation across multiple states isn’t simple, but PHS has expanded into nine states, including Texas, Oklahoma, Kansas, Missouri and Arizona. Their model relies on licensed mobile phlebotomists, X-ray technologists and sonographers, all trained to provide high-level care outside traditional hospital settings.

The financial impact for patients is significant. Instead of ambulance rides and ER visits costing thousands, PHS services often cost just a fraction, sometimes only tens or hundreds of dollars.

“Traditionally, without mobile diagnostics, the patient would be loaded into a transportation vehicle, typically an ambulance, and taken to a hospital,” Dieter says. “Our approach is a fraction of the cost but brings care directly to the patients.”

The company has also embraced predictive and personalized medicine, offering genetic tests that guide medication decisions and laboratory tests that predict cognitive decline from conditions like Alzheimer's and Parkinson’s.

“We actively look for complementary services to improve patient outcomes,” Dieter says. “Precision medicine and predictive testing have been a great value-add for our providers.”

Looking to the future, PHS sees mobile healthcare as part of a larger trend toward home-based care.

“There’s an aging population that still lives at home with caretakers,” Dieter explains. “We go into the home every day, whether it’s an apartment, a standalone home, or assisted living. The goal is to meet patients where they are and reduce the need for hospitalization.”

Light highlighted another layer of innovation: predictive guidance.

“We host a lot of data, and labs and imaging drive most treatment decisions,” Light says. “We’re exploring how to deploy diagnostics immediately based on results, eliminating hours of delay and keeping patients healthier longer.”

Ultimately, innovation at PHS isn’t just about technology; it’s about equity.

“There’s an 11-year life expectancy gap between major metro areas and rural Texas,” Dieter says. “Our innovation has been leveling the field, so everyone has access to high-quality diagnostics and care, regardless of where they live.”

Aegis Aerospace appoints Houston space leader as new president

moving up

Houston-based Aegis Aerospace's current chief strategy officer, Matt Ondler, will take on the additional role of president on Jan. 1. Ondler will succeed Bill Hollister, who is retiring.

“Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers,” Stephanie Murphy, CEO of Aegis Aerospace, said in a news release.

Hollister guided Aegis Aerospace through expansion and innovation in his three years as president, and will continue to serve in the role of chief technology officer (CTO) for six months and focus on the company's technical and intellectual property frameworks.

"Bill has played an instrumental role in shaping the success and growth of our company, and his contributions leave an indelible mark on both our culture and our achievements," Murphy said in a news release.

Ondler has a background in space hardware development and strategic leadership in government and commercial sectors. Ondler founded subsea robots and software company Houston Mechatronics, Inc., now known as Nauticus Robotics, and also served as president, CTO and CSO during a five-year tenure at Axiom Space. He held various roles in his 25 years at NASA and was also named to the Texas Aerospace Research and Space Economy Consortium Executive Committee last year.

"I am confident that with Matt at the helm as president and Bill supporting us as CTO, we will continue to build on our strong foundation and further elevate our impact in the space industry," Murphy said in a news release. "Matt's vision, experience, and understanding of our evolving markets position us to build on our foundation and pursue new frontiers."
