This walks you through Hexa's methodology for defining your ideal customer profile, which is actually useful if you're a founder who keeps saying "everyone could use this." It forces you to map the entire buying center (not just the end user), build bottom-up from company profile to buyer to user personas, and then run the 50-company test where you literally list 50 companies, find real buyers at 20 of them, and reach out to 10. The pain hierarchy scoring is solid for prioritizing which problems to solve first. If you can't complete the 50-company test, your ICP is too broad and you'll waste time on scattered sales conversations.
