matteo In my experience the international platforms dominate and are more then enough when you host an event in Vienna, there are still some local ones worth trying: International: Eventbrite Meetup.com luma (not that big in Vienna yet, they also don't have a Vienna page yet) Local: Falter Events Brutkasten Events: I don't think I've gotten in there in the past as I was always too late. Austrian Startups was good in the past, but I don't see any significant traffic coming from there anymore. Others: Xperience: I've heard about that one but never tried.
