While Milkify's founders — husband and wife team Pedro Silva and Berkley Luck — secured partners on a popular business pitch and investment show, the entire experience almost didn't happen.

Silva and Luck, who got her PhD in molecular and biomedical s at Baylor College of Medicine, founded the company to provide breast milk freeze drying as a service to Houston-area families. Now, Milkify has customers across the country, but the duo didn't know if going through the process would be worth the investment and publicity, or if it would just be a distraction.

"The competitor in me wanted to be the first breast milk company to go on the show and to tell our story to the world — to show the world what my wife came up with that we thought was so great," Silva says on the Houston Innovators Podcast. "It was probably the scariest 45 minutes of my life."

But the sharks bit. Milkify's episode aired in April, and two investors — Gwyneth Paltrow and Lori Greiner — agreed to a $400,000 convertible note for 20 percent equity in the company. Paltrow even said on the show that she would have used the service when she was breastfeeding.

"It was empowering," Luck says of getting to wear her white coat on TV and share the story of how she came up with the idea of Milkify. "It was important to me when we went on the show to express that this had a scientific basis, that we didn't start this lightly, and that we've made huge strides in doing this in the absolute safest way possible."

Silva says they can't talk about some of the details of the show or the deal, but since then, Milkify has reached new customers, received additional investment interest, grown its team, and built out its plan to scale, the founders shared on the podcast. The team also shares its big-picture scale plans, which include tapping international partners to potentially take Milkify's tech global.

"Our vision is for every family to have access to breast milk formula, but instead of re-creating breast milk in a lab, we're doing it with mom's own milk," Silva says, mentioning a partnership with a breast milk bank that will convert its operation from freezing to freeze drying donated milk. "We're also working with groups in the UK and Australia to launch similar services using our patented technology."

"By the end of the year, we hope to see some announcements with those partnerships across the globe."

From the beginning, the importance of Milkify's team has been on supporting working parents to give them the best way to care for their families, Silva says. And for Luck — who says she's proud of the integrity Milkify has at its core despite competitors offering lower-quality and, in some cases, dangerous alternatives — she sees a lot of research benefits for the company.

"It's amazing to be at this leading edge, not just of innovation but of research, and to be able to still put out meaningful advances as an industry partner, not just as an academic," Luck says, adding that she hopes to be able to continue to contribute to the ongoing research into breast milk.

Luck and Silva share more about their Shark Tank experience, their co-founder strengths, and the future of Milkify on the podcast. Listen to the interview here — or wherever you stream your podcasts — and subscribe for weekly episodes.

After catching a deal on Shark Tank, these Houston-area fish foodies swim toward more funding

reeling in cash

The benefits of working more fish into your diet are as endless as the vast ocean itself, but going about buying and cooking fish is an expensive and daunting process.

Houstonians Melissa Harrington and Emily Castro thought they could help and launched Fish Fixe in 2017 to tackle these challenges and bring high quality seafood direct to consumers. Fish Fixe delivers seafood with easy-to-access instructions on storage and thawing — plus cooking recipes that take around 20 minutes.

The duo launched the company in 2017 and appeared on the 13th season of Shark Tank last year. In 2020, with more people avoiding grocery stores and restaurants, they saw a 400-percent increase in sales. They pitched asking for $200,000 in investment. Lori Greiner, the "queen of QVC," took the bait — and 25 percent equity.

“COVID-19, which forced more people to eat at home and adopt direct-to-consumer services, and Shark Tank were both spring boards for our sales, and through these events we've been able to retain many customers,” says Harrington.

In order to sustain this growth and provide more opportunities to scale, Harrington and Castro put the Shark Tank investment into their distribution line and moved everything into a centralized distribution center which replenishes distribution centers in other parts of the country.

“By late Q2, we will have four distribution centers that can hit 99 percent of the US in less than two days,” says Harrington.

Up next, Harrington and Castro have their sights set on the customer experience and the content space, which they hope to support with some outside funding.

“We are going to go raise some money because we truly feel that with the right resources we can scale and serve more people and spread the message,” says Harrington. “The hard work, we kind of feel like, has already been done in the setup and now it’s time to go have fun and go market, which is really fun.”

Prior to Fish Fixe, Harrington and Castro both worked in food and beverage. Harrington worked in the live lobster business and sold lobsters to high-end Houston restaurants and HEB. Castro worked in wine and spirits and managed a team of 50 sales professionals. Leveraging that depth of experience, they were able to bring Fish Fixe from concept to market in 90 days.

Houston lab-test startup seeks $1M for nationwide expansion

Testing Access

Health care industry veteran Jim Gebhart knew there had to be a better way for patients to access lab services, especially those with high health insurance deductibles or no insurance at all.

“This challenge became deeply personal when a close family member developed a serious illness, and we struggled to secure prompt appointments,” Gebhart tells InnovationMap. “It’s incredibly frustrating when a loved one cannot receive timely care simply because of provider shortages or the limited capacity of traditional clinics.”

Driven by the desire to knock down lab-test barriers, Gebhart founded Houston-based TheLabCafe.com in 2024. The platform provides access to low-cost medical tests without requiring patients to carry health insurance. TheLabCafe serves patients in six states: Texas, Georgia, Louisiana, Nevada, New Mexico and Oklahoma. Gebhart, the startup’s CEO, says that by the end of March, LabCafe will be offering services in 20 more states and the District of Columbia.

Gebhart has spent more than 30 years in the lab industry. His career includes stints at Austin-based Clinical Pathology Laboratories, Ohio’s Cleveland Clinic Laboratories and Secaucus, New Jersey-based Quest Diagnostics.

“Since nearly 80 percent of disease diagnoses rely on laboratory testing, I decided to leverage my background to create a more accessible, self-directed process for individuals to order blood and urine tests on their own terms — when and where they need them,” says Gebhart.

So far, Gebhart is self-funding the startup. But he plans to seek $700,000 to $1 million in outside investments in late 2026 to support the nationwide expansion and the introduction of more services.

TheLabCafe contracts with labs for an array of tests, such as cholesterol, hepatitis, metabolic, testosterone, thyroid and sexually transmitted infection (STI) tests. A cholesterol test obtained through TheLabCafe might cost $29, compared with a typical cost of perhaps $39 to $59 without insurance.

A health care professional reviews every test, both when the test is ordered and when the results are delivered, often within 24 hours. After receiving test results, a patient can schedule a virtual visit with a health care professional to go over the findings and learn potential treatment options.

Gebhart says TheLabCafe particularly benefits uninsured patients, including those in Texas. Among the states, Texas has the highest rate of uninsured residents. U.S. Census Bureau data shows 21.6 percent of adults and 13.6 percent of children in Texas lacked health insurance in 2024.

“Uninsured patients often pay the highest prices in the health care system,” Gebhart explains. “We address this by offering straightforward pricing and convenient access to testing without requiring insurance.”

“Our rates are intentionally set to remain affordable, helping individuals take a proactive approach to their health,” he adds. “Regular testing enables people to identify potential health issues early and track their progress as they make lifestyle changes. Ultimately, you can’t measure improvement without data — and laboratory results provide that data.”

Houston geothermal startup secures $97M Series B for next-gen power

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.
