Unpopular opinion: your first 10 users matter more than your first 100

Everyone chases signup numbers early on. i think that's backwards.

10 people who actually use your product and complain about it teach you more than 100 who signed up and forgot you exist.

I've got 8 paying users right now for Banalo.Business. haven't even scaled outreach yet, just been obsessing over what those 8 actually do inside the product.

Curious what others think, early on do you optimize for more users, or deeper usage from fewer?
