How to meet Angels..
Whats your experiences? Thoughts.. Is it a simple email? Is it some meetup group? Is it a referral? What if you don't know anyone? Where to begin? Luck?
But seriously, other than AngelList (which is great if you have product+traction), go to meetups and network. If you're not in a tech hub (Bay area, NYC, Boston, London), move to one. Best of luck!
