You are far better just soliciting for partners on HN or other startup sites of which there are plenty with plenty also looking to partners.
Hate to sound cynical and/or degrading but moat I've met through meetups and alike groups are all wannabes.
However like anywhere else, there are still plenty like myself who wants to get started on that endeavor too.

The only time you maybe be successful is if you are already funded.
But there is one advantage of doing all that in the Valley; funding is easy. Almost every serious meetups have someone in VC world scouting.

btw the "it" place(s) to be is Palo Alto and SF.
It as mentioned before breaking in and getting noticed is impossible unless you already got in roads with connected ppl.
Ol adage: It's WHO you know not WHAT you know.
