I still say the easiest form of validation is a PowerPoint or forum post. You have to practically smell their excitement. Look for the glint in their eyes, not data. I think what really matters is they can give honest feedback with little friction, and you can track churn. You should also be able to have a conversation with your earliest users. The best thing for feedback is an in-app chat room. I've tried setting up a Discord or a feedback form, these are relatively bad. And then just track that they come back. This could be Google Analytics on a landing page. Until they're hooked, the goal is product, and paid marketing is a waste.
