What we are currently doing: 1) Cold outreach to power users - to convert them into affiliates. 2) Cold outreach to individuals who have target ICP communities. 3) SEO for more long term (not for the first 500)
• Make a great product. Everyone tells you "build it and they will come" is not working anymore, but it's working _for me_.
• Outreach via your network. Talk to people with the intent of learning, not selling.
• I'm personally on a freemium model. But that's in the developer-to-developer market, which is vastly different from your B2C
EDIT:

The need is real, and the problem is real. I am one of the users myself. I built it because I felt the need myself. I ran the MVP with 15 others in my network with similar profiles. Quesiton is how to scale beyond that.
I almost didn't buy the great book The One Billion Dollar App because of hits clickbait title, but it actually well-elaborates the mechanics (and the mathematics) of viral spread of apps, which not by coincident corresponds to the familiar formulas that people will have seen during the CoViD19 pandemic ("r-coefficient", r or R0 [1]).
For example, if you have a mobile app that gives you something free for each friend you invite to it, it may encourage some folks to share with r friends...
