How to fight with your co-founder

Every founding team is a mix of personalities, communication styles, and strengths. That can be a superpower or cause founders to butt heads. Without a clear framework for navigating conflict, even the strongest teams can fall apart before they really get started. This week on Build Mode, Isabelle Johannessen sits down with Ian Schmidt, strategic advisor at Trimergence, to unpack the “personal operating system” behind every founder. As a coach, consultant, and occasionally a bouncer, Ian helps teams build the self-awareness and relational tools they need to scale without unnecessary friction. They discuss: 🧩 Why founders should invest in coaching before conflict escalates 🧩 How to repair after conflict goes sideways 🧩 The importance of understanding your own triggers as a leader 🧩 How to create space for the self-work that actually saves time long-term Following last week’s episode on family co-founders, this conversation expands those lessons into practical tools any founding team can use.
