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 university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”
