Do people have thoughts or pointers for building something users love when your product depends on there being enough users using the product? Dating apps, platforms and such.

When a single user gets no utility from your product if there aren't enough already using it, what does one do? You kind of have to spend some money marketing to get the initial word out. This is something I've been struggling with. We've been doing a lot of writing content and there's some word of mouth happening. We spend small amounts on FB too. But we're seeing a lot of users drop off with the reason "there just aren't enough other people using this".
