Searching for Fit is the process of designing value propositions around products and services that meet jobs, pains, and gains that customers really care about. Fit between what a company offers and what customers want is the number one requirement of a successful value proposition. Fit happens in three stages. The first occurs when you identify relevant customer jobs, pains, and gains you believe you can address with your value proposition. The second occurs when customers positively react to your value proposition and it gets traction in the market. The start-up movement calls these problem solution fit and product-market fit, respectively. The third occurs when you find a business model that is scalable and profitable.
