Lindsay Mullenger turned a quiet moment of organizing her child’s nursery into a Shark Tank–backed business. What started as a personal need for a meaningful keepsake box became Petite Keep, a company that won over Jamie Kern Lima, Mark Cuban, and Barbara Corcoran. 

From balancing a corporate career and motherhood to assembling products by hand with her family, she built her business with a mindset of “we figure it out.” Today, Lindsay runs a fast-growing company powered by community, storytelling, and a female-led team. 

Join us as we unpack her Shark Tank experience, the marketing strategies that fueled her growth, and the mindset shifts that every aspiring leader and entrepreneur can apply to transform a simple idea into something extraordinary.

"Our core values are: be curious, grow every day, and own the outcome." ~ Lindsay Mullenger
