This week on Build Mode, we’re diving back into the archives for a special best-of episode all about startup mistakes, hard-earned lessons, and the decisions founders wish they’d made differently.
Host Isabelle Johannesen and producer Maggie Nye revisit some of the most insightful conversations from past seasons to explore the missteps that shaped successful companies. Guests share candid stories about chasing product-market fit, making hiring mistakes, navigating investor expectations, managing hypergrowth, building company infrastructure, and learning what really matters in the early days of a startup.

Jasper Carmichael-Jack, cofounder & CEO of Artisan
Yuri Sagalov, partner at General Catalyst
