A Houston startup is competing in the "Super Bowl of Business," as founder Pedro Silva calls it, and you can watch the action later this week.

Milkify will appear on ABC’s “Shark Tank” this Friday, April 7. Silva, co-founder and CEO, created Milkify along with his wife, Berkley Luck, PhD, in 2019. Today, Luck is a mom, COO, and a molecular biologist, but she had the idea for the company back in grad school. A coworker was struggling with pumping breast milk “lugging the pump back to work,” as Luck puts it.

Luck was studying probiotics at the time and was using a freeze-dryer in her work. The problem inspired her to create a process of freeze-drying breast milk that is now patent pending. The trademarked process is centered around SafeDry, special freeze-drying pouches.

“The breast milk never makes contact with our equipment,” Luck explains. The powdered milk is transferred directly from the bag in which it’s freeze-dried to the final packaging under sterile conditions. The result is not only shelf-stable, but keeps for at least three years, exponentially longer than frozen milk.

Silva admits that when Luck first pitched Milkify to him, he thought it was a crazy idea. “But Berkley is way smarter than I am. There must be something to it,” he realized. At the time, he was working in energy private equity. But he vowed that if they could find a viable path to making Milkify a business, he would join Luck full-time.

Early in the company’s life, the couple purchased a blue van that said “We will freeze-dry your breast milk,” recalls Silva. This grassroots marketing introduced them to a neighbor whose baby refused to drink her frozen milk. “He spat it out, he hated the taste,” Silva says. The pair freeze-dried her milk for the baby and their neighbor soon sent a video of the little one chugging six ounces of her rehydrated milk.

“That was the lightbulb moment,” says Silva. “How often do you get to work on something really meaningful?”

Since its founding, Milkify has freeze-dried and powdered more than half a million ounces of breast milk, all carefully preserved and packaged individually. Last October, Milkify opened what Luck claims is, “The only GMP-certified processing facility in the world right now specifically designed for freeze-drying breast milk.”

The 6,400-square-foot Houston space is a vast improvement from the previous 200-square-foot facility. That was thanks to raising $1.2 million in funds, which has also allowed them to build a larger staff.

“Our entire workforce at this point other than Pedro is moms,” says Luck. Including the couple, they are a team of 10, and just hired two additional members. They are currently looking to hire, says Silva, with roles including both operations and logistics associates. Experience, he says, is less important than conscientiousness and a good attitude, as they will train their new hires in-house.

And Milkify is about to receive more attention than ever with its appearance on “Shark Tank.” “Getting on a national stage to share our story was the main motivation for it,” says Luck. That translates to both education about the potential for freeze-drying breast milk, and about Milkify’s unique model.

“We started this business as a labor of love. It wasn’t just a financial reason,” says Silva. “This can actually help a lot of people. This is a way to spread the word.” And in the process, help countless moms and babies.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
