Petite Keep Net Worth Shark Tank Update 2025 

We all have those special moments in life that we want to hold onto forever. Baby clothes, wedding memories, or even sports trophies, these are the things that tell our stories. But often, these precious items end up stuffed in plain plastic bins, forgotten in attics or basements, gathering dust. Lindsay Mullenger saw this problem and decided to do something about it.

She created Petite Keep, a line of elegant storage trunks designed to preserve and celebrate life’s most cherished memories.  

Lindsay’s vision was simple: to give families a beautiful way to store their keepsakes. These trunks aren’t just functional; they’re personalized and stylish, making them a perfect addition to any home. Her goal was to turn storage into something meaningful and elegant.  

In Shark Tank Season 16, Lindsay pitched her business, seeking $400,000 for 5% equity in Petite Keep. She shared her journey, from starting the company in 2020 to achieving millions in sales. The Sharks were impressed, but not all were convinced. After some intense negotiations, Lindsay walked away with a deal. Let’s dive into the details of her pitch, the Sharks’ reactions, and what happened to Petite Keep after the show.

Lindsay Mullenger Backstory + Initial Pitch   

Lindsay Mullenger’s journey began with a simple observation. She noticed how families, including her own, struggled to preserve their most important memories. Baby clothes, wedding dresses, and other sentimental items were often stored in unattractive boxes or bins, hidden away and forgotten. Lindsay wanted to change that.  

In February 2020, she launched Petite Keep, a company that creates high-quality, customizable storage trunks. These trunks are designed to protect keepsakes while adding a touch of elegance to any room. Lindsay started small, selling her products directly through her website. By the end of 2020, she had made $110,000 in sales.  

Over the next few years, Petite Keep grew rapidly. In 2021, sales jumped to $660,000. By 2022, the company hit $1.7 million in revenue, and in 2023, sales reached $5 million. Lindsay projected $10 million in sales for 2024.  

During her Shark Tank pitch, Lindsay explained her business model. She offered three trunk sizes: the Mini ($195), the Petite ($275), and the Grand ($350). Customers could personalize their trunks with thousands of design options, making each one unique. Lindsay also shared that her customer acquisition cost was $86, and her profit margins were around 7.5% in 2023.  

Her ask was clear: $400,000 for 5% equity to help scale the business, reduce customer acquisition costs, and bring her elegant trunks to more families.  

Queries + Sharks’ Responses, and Final Deal    

The Sharks had a lot of questions for Lindsay. Here’s how the conversation went:  

Mark loved Lindsay’s product and admired her business growth. However, he admitted he wasn’t passionate about the product itself. He said, “You’ve done an incredible job, but this isn’t for me.” Mark decided to bow out of the deal.  

Barbara was impressed by Lindsay’s success but felt she didn’t need a partner to grow further. She said, “You’re doing great on your own. I don’t think you need me.” Barbara also exited the negotiations.  

Lori admired Lindsay’s creativity and business skills but felt the equity ask was too high for what she could bring to the table. She said, “I love what you’re doing, but I can’t make the numbers work.” Lori decided not to make an offer.  

Kevin saw potential in Petite Keep and wanted to help improve marketing efficiency. He teamed up with guest shark Jamie Lima, offering $400,000 for 20% equity. Kevin said, “I believe in your business, but I need a bigger stake to make it worth my while.”  

Jamie was excited about the product and offered $400,000 for 10% equity, but only if another Shark joined the deal. She said, “I love your vision, but I want a partner to help grow this.”  

After some back-and-forth, Lindsay countered with $400,000 for 10% equity. Kevin and Jamie refused, so she proposed $600,000 for 12% and 15% equity. Eventually, Mark and Barbara reentered the deal, offering $400,000 for 15% equity. Jamie joined them, and they agreed to split the equity equally, with each Shark taking 5%. Lindsay accepted the offer and left the Tank with a deal in hand.
