INSIGHT

Co-founder Conflict Damages Company Stability

Co-founder conflict creates a ripple effect that damages company stability and retention.
Matthew Jones explains employees see founders' fights as a signal that the company is unsafe, driving churn and anxiety.

ADVICE

Run Co-founder Syncs And Dates

Schedule two distinct rituals: short operational co-founder syncs and longer co-founder dates focused on the relationship.
Matthew Jones recommends asking one simple question on dates: "How are we doing?" to surface meta communication.

ADVICE

Use A Structured Conflict Navigation Process

Use a repeatable conflict navigation process before hiring a coach: contain the conflict, prepare, frame the conversation, and agree actionable follow-ups.
Matthew Jones's book offers scripts and steps teams can follow end-to-end.
