Sara Wyman, founder and CEO of Stackpack, joins me to share her journey from investment banking and a Wharton MBA to launching a company that’s redefining how finance and operations teams manage vendors. From surviving the Bear Stearns collapse to scaling Etsy and Affirm through IPOs, Sara’s career has been built on spotting patterns and acting with conviction. In this episode, she breaks down how she validated her idea with 75 CFOs before writing a line of code, why timing and conviction matter more than a perfect resume, and what it really takes to leave the safety of corporate life to build something of your own.

Key Takeaways

• Why solving a problem you’ve lived through yourself is the best foundation for a startup

• How interviewing potential customers before building can double as both research and sales

• Why founders should outsource what they’re not great at instead of spinning wheels

• The hidden advantage of years of work experience when stepping into a founder role

• Why pace setting—not just hiring—is one of the founder’s most critical responsibilities

A Standout Moment

“If you’re not awesome at something, outsource it or find the person that is. You don’t get bonus points for struggling through work that isn’t your strength.”

Talk to customers before you build. Sara’s early interviews not only validated her idea but converted into her first paying design partners.
