The early days of e-commerce were chaotic. No Shopify, no Klaviyo, no attribution dashboards. In this conversation, Jennifer turns the tables and interviews Mark about the path that began with a phone call from a man selling hammocks in Washington and eventually led to Hayneedle’s sale for hundreds of millions. Their story was built inside a Barnes & Noble, fueled by instinct, trial-and-error, and a long list of decisions that shaped modern online retail.

Mark shares what it felt like to scale from a single product site to more than 300 niche stores, how customer curiosity became the catalyst for entire categories, and the moments where listening to his gut would have saved millions.

If you’re building, scaling, or thinking about your next chapter, this conversation offers the kind of clarity only lived experience can give.

FrostBuddy didn’t start with a pitch deck or a perfect plan. It started with two brothers in a small Illinois town who were curious enough to chase an idea and resilient enough to keep going when the market got crowded.

In this conversation, Brock and Mitch Mammoser walk through the early days, the decisions that shaped their momentum, the people they trusted along the way, and the mindset that helped them scale from a few samples to a business approaching $70 million this year.

Their honesty about growth, pressure, community, and identity makes this one of the most grounded founder stories we’ve shared, and a powerful look at what it actually takes to build a modern e-commerce business without losing yourself in the process.
