I built my product. Now I have no idea how to get users!

I’ve built VIViD, a deep interactive work-fit assessment that helps people understand whether they are in the wrong role, the wrong company or the wrong environment. I believe it's unique in its offer.

The product is live. The problem is distribution.

I have no audience, no email list and very little experience with X, Instagram, LinkedIn, Reddit or paid ads. I also don't have the funds to just buy traffic, so I thought I'd ask advice here.

For those of you who started from zero:

How did you get your first 10 paying users?

What would you focus on first if you were launching today?

What channels would you ignore?

I’m not looking for hacks. I’m trying to understand what actually works when you have a real product but no audience. Any other advice will be gratefully received
