The Ideal Customer Profile (ICP) is a detailed description of a startup's ideal customer, based on characteristics such as industry, company size, needs and behaviours that represent the highest value and best fit for the product or service. Defining an ICP enables companies to target their marketing and sales strategies, increase the efficiency of customer acquisition and optimise resource allocation. By focussing on the Ideal Customer Profile, start-ups can improve customer satisfaction, increase customer loyalty and ultimately accelerate company growth.
