Why product-market fit is not enough: 4-fits framework

Achieving product-market fit is often seen as the key to product success, but it is only one element of a more comprehensive framework necessary for building successful products. Beyond product-market fit, which ensures that a product addresses a significant user problem, other critical aspects include product-channel fit, channel-model fit, and model-market fit. Product-channel fit involves aligning the product with the rules of the chosen growth channel to effectively reach users, while channel-model fit ensures that the average revenue per user (ARPU) can cover customer acquisition costs (CAC). Model-market fit assesses whether the monetization model aligns with the target market's willingness and ability to pay, allowing the product to scale. Focusing solely on product-market fit can lead to neglecting these other dimensions, which are crucial for distribution, revenue generation, and long-term scalability. The article suggests that building successful products is about balancing these four fits to create solutions that provide business value at scale, requiring ongoing experimentation and adaptation.
