What does it really mean to build in stealth—and when does it help or hurt? In this episode, Amir sits down with Yoni Michael, co-founder of Typedef, an AI infrastructure startup that recently came out of stealth. Yoni shares why his team chose to stay under the radar early on, how they balanced secrecy with customer discovery, and the lessons they learned about finding product-market fit in a noisy AI landscape. If you’re a founder or tech leader navigating early-stage strategy, this conversation offers practical insights you can apply right away.
Key Takeaways
• Stealth mode isn’t all or nothing—there’s a spectrum between total secrecy and open visibility
• Execution and speed of iteration matter more than protecting “the idea”
• Customer discovery should start before you even write code
• Messaging is never final—test, refine, and keep adjusting as you learn from design partners
• Investors expect shifts at the seed stage, but keeping them in the loop builds trust
