Sam Altman discusses the initial challenges of user retention experienced by ChatGPT, highlighting that even a small percentage of retention indicates a product is in a favorable position. He emphasizes that startup founders should recognize the value of retaining any users, as the default retention rate tends to approach zero.

While some perceive these wrappers as temporary solutions, those that incorporate unique data, simple UI, domain expertise, community engagement, and deep integration can establish a lasting presence in the market. It's essential to create a strong moat early on to ensure long-term relevance.
