The challenges new mothers face when it comes to breastfeeding, especially when it comes to storing breast milk. Traditional methods of freezing milk can be messy, take up too much space, and can lead to problems like spoiled milk. This process can be even more complicated for mothers who work or travel often.
Dr. Berkeley Luck, a researcher, noticed these challenges while working in a lab and decided there had to be a better solution. In 2019, she and her husband, Pedro Silva, created Milkify, a service that freeze-dries breast milk into a lightweight powder that can be stored without refrigeration. This method not only makes it easier to store milk, but it also extends its freshness for up to three years while maintaining its nutritional value.
They showcased Milkify on Shark Tank, seeking an investment of $400,000 for a 10% ownership stake in their company. While there were mixed reactions from the sharks, with some concerned about the cost for families, others recognized the potential of the product.
Ultimately, Lori Greiner and Gwyneth Paltrow offered them $400,000 for a 20% stake through a financial arrangement that allows flexibility over time. This partnership helped Milkify grow further after appearing on the show.

Dr. Berkeley Luck and Pedro Silva Backstory + Their Initial Pitch
Dr. Berkeley Luck, who has a background in studying tiny organisms and human health, didn’t initially plan to become an entrepreneur. However, she noticed that many mothers faced challenges when it came to storing breast milk. Traditional methods, like freezing, were messy, took up a lot of space, and weren’t always reliable over time. Wanting to help solve this problem, she partnered with her husband, Pedro Silva, to create a product called Milkify.
The main idea behind Milkify was to freeze-dry breast milk instead of just freezing it. Freeze-drying removes the water content while preserving all the important nutrients, allowing the milk to be turned into a fine powder. This powder can be kept at room temperature for years and can be easily reconstituted with water to become liquid milk again.
When they appeared on Shark Tank, they brought samples of their freeze-dried milk and even demonstrated the process using Berkeley’s own breast milk to show it’s both safe and effective. They explained that their service costs around $1.60 for each ounce of milk, with typical orders costing about $475.
At that time, Milkify had received $2 million in orders and had made $525,000 in total sales. They were planning to expand their operations to meet growing demand and projected revenues of $3 million by the following year. Although their presentation was compelling, the investors on Shark Tank raised some concerns about their business.
Queries + Shark’s Responses, and Final Deal
Mark found the service to be a clever idea, but thought it was too pricey for most families to afford, suggesting it felt exclusive or like a luxury item. Because of this, he decided not to invest.
Kevin shared Mark’s view and added that only wealthy mothers could realistically buy this service. He felt that the target market wasn’t large enough to justify an investment, so he opted out as well.
Barbara also believed the price was too high and echoed that it was mainly for wealthy mothers. She, too, chose not to invest.
Gwyneth was interested in the idea. She wanted to know more about how many potential customers there were. The founder, Berkeley, explained that 2 million mothers freeze breast milk each year, and Pedro added that a significant portion of their customers (60%) were from middle- or lower-income families.
Lori saw promise in the business but had concerns about how much the business was valued at. She and Gwyneth discussed the possibility of teaming up to make an investment offer.
Pedro, the founder, proposed a convertible note, which is essentially a loan that could change into ownership shares if the business does well. After some negotiations, Lori and Gwyneth agreed to invest $400,000 in exchange for 20% of the company through this convertible note. The founders accepted their offer, securing funding from two investors.
In essence, the investors were divided on the idea due to pricing, with some wary about the target audience, but ultimately, a deal was made with two of them willing to invest.

3. Send It In: The moms collect their breast milk and send it to Milkify’s facility using the cooler.
