Episode notes
In startups, choosing a co-founder is often compared to choosing a spouse. But what happens when your co-founder actually is family? In this episode of Build Mode, host Isabelle Johannessen explores how founders navigate co-founder relationships that come with built-in trust and unique challenges. First up is Hala Jalwan and Alessio Tresanti, the married co-founders of AI agent for procurement focusing on autonomous sourcing, Rivio. They discuss building a company from the same household and why clear roles and communication matter when both your personal and professional lives are on the line. Then Isabelle talks with Anna Sun, co-founder of Nowadays, an AI co-pilot for corporate event planning that she launched with her sister Amy shortly after graduating from MIT. Sun explains how their sibling dynamic shapes decision-making, team culture, and the way they move quickly as founders.
