This document discusses the challenges of achieving product-market fit for startups. It argues that product-market fit is more complex than simply building an MVP and measuring customer usage and revenue. True product-market fit requires considering the product value, business model, and ecosystem in which the product exists. It emphasizes the importance of understanding customer needs deeply and solving meaningful problems, rather than focusing solely on product features or growth metrics. Achieving product-market fit is an iterative process of learning through building, measuring, and refining based on customer and market feedback.
