The document discusses the differences between natural product-market fit (NPMF) and artificial product-market fit (APMF). It notes that NPMF is achieved through bootstrapping, winning organic users, listening to feedback, and iterating quickly. In contrast, APMF is achieved through buying growth, which can lead to addiction and lack of long term viability. The document advises that after achieving NPMF through bootstrapping, companies should continue listening to feedback to further improve their product.
