Talking to potential customers one at a time is the simplest thing that might work. And it will be work. Hard work. If you don't want that hard work, don't have customers. Talking to customers one at a time is hard to scale and it is easy to scale zero customers. This mostly makes solutions that scale attractive when starting out. Scaling when you have many customers is hard work. Harder work than talking to customers one at a time. Good luck.
