I think it used to be the case (not sure if this is still true) that if you were an official NetSuite Partner you could like sign up for creating/sponsoring an official user group in particular region with NetSuite and they would kick in some resources or guest speakers or something, but might've been some strings attached 🤷♂️. Also there's the official NetSuite events:
