Idea: Just hang out for an hour or two on a Thursday or so with absolutely no agenda but to find someone to talk to about professional issues, start up challenges etc. In return perhaps meet someone interesting, may be a partner, co founder or an employee.
I'm an amateur re meet ups, pardon in advance. By definition should be in small groups. I am scared of wasting time going to these events having to listen to the talks much of which can be found and learned.
Recommendation: Organize small and personalized events for serious entrepreneurial people so that they can make meaningful connections that are professionally rewarding.
For example: I left running bulk of a multi billion international company. I cant find a good hands-on engineer to join as my technical partner. I am new to meetups hoping that I'd make some meaningful professional connection. As an entrepreneur I put a premium on the hours I have on hand.
