Disclaimer: Non-dev small business owner here; I only MVPed offerings that solve a big-enough existing problem of contacts I know -- so for me the logical customers to validate are the ones with the pain points that I can comfortably access. For people who are comfortable enough to give you a signup already I'd just reach out to them first via a cold+mass email and get conversion through numbers. Once you get that personal connection you just wanna make sure it solves their use case; do remember how you solve it for them is often times as important as solving it itself.
