In this episode of the Building Great Tech podcast, hosts Simon Hook and Anastasija Krysa delve into a critical yet often overlooked issue in the startup world: the hidden costs of a toxic co-founder. Drawing on insights from Harvard Business School, they reveal that over 65% of startups fail due to co-founder conflicts, rather than market conditions or product issues. Simon and Anastasija discuss the detrimental effects of unresolved disputes, including time drains, decision paralysis, and the impact on team morale and productivity. They also share real-life stories, such as the tumultuous history of Tinder and the rise of Bumble, highlighting the importance of mutual awareness and understanding in co-founder relationships.
