How to build a company you’ll run forever | Zack Kanter (Founder and CEO of Stedi)
In Depth
Signs of urgency and buying despite imperfections
Brett asks about differences; Zack outlines speed to close, urgency, and customers buying despite missing features.
Zack Kanter is the founder and CEO of Stedi, an API-first healthcare clearinghouse. After bootstrapping a wildly profitable auto-parts business, he sold it to tackle "the most complicated problem" he'd ever encountered: business-to-business transaction exchange. He spent years building EDI infrastructure, threw away the entire codebase eight times, and found extraordinary traction in healthcare. Stedi recently raised a $70M Series B co-led by Stripe and Addition. In this conversation, Brett and Zack discuss why venture capital means "going pro," why execution is never actually a moat, and how "eating glass" became Stedi's competitive advantage.
In today’s episode, we discuss:
- How 16-year-old Zack turned $2,500 into a wholesale empire
- Why bootstrapping means being "constrained by capital" and how VC removes that ceiling
- Why Zack rebuilt their EDI product eight times before launch
- The snake swallowing a deer: what extreme product-market fit really looks like
- What software companies can learn from discount retail and Toyota
- Why Stedi’s new hires are told "everything’s your fault now"
- And much more
