After nine years of investment experience, IOSG Ventures has identified six types of founders they avoid investing in, based on patterns observed over four market cycles. The review, led by founder Jocy, highlights traits such as emotional instability, lack of hunger due to safety nets, and uncontrolled ego as key red flags. Additionally, founders who prioritize token over product, lack a clear exit strategy, or have not experienced a full market cycle are also considered high-risk. IOSG emphasizes the importance of founder traits and project structure in determining success. They note that successful founders are often deeply obsessed with solving specific problems, possess strong communication skills, and demonstrate controlled ego and resilience. The review aims to help both investors and entrepreneurs avoid common pitfalls and improve decision-making in the volatile crypto market.
