A couple of things that might help you get started:

New York Tech Meetup (now the New York Tech Alliance) - https://nytm.org/ (meetups happen monthly; events happen regularly, check the site for the schedule)

Co-working spaces in NYC - there are new ones popping up (and shutting down) all the time throughout different parts of the city. Probably easiest to search for co-working spaces near where you live. I haven't been to any in awhile, but a Google search should get you a decent list.

New York Tech Week - http://techweek.com/newyork-schedule/ (this happens in the fall, but you can still get an idea of popular companies and people from the speaker list. More of an information source.)

Thanks! These are all very useful.
