Your friend is starting a company and wants to identify the job their product will do for people. What advice would you give them?
Make your best guess based on the reason you’re starting your company.
Wait until you have at least 100 customers, and then interview 10 or 12 of them.
Put a plan in place to interview your first few customers soon after they buy from you.
Ask customers of your competitors why they bought the products they did.
