Love the landing page and the Swedish city references :) I'm working on something similar, actually, but in the lunch/dinner niche. It's a nice feeling to build something that you actually use yourself to meet other people, but I find it's hard to scale beyond that. What are the major features you're missing before making it an open sign up?

Btw for ticketed events, I've seen that https://posh.vip has been growing pretty quickly for music performers.. maybe some inspiration for you there.
