Hey man great post!
I personally have never succesfully gotten funding from pitching events. Most of mine investors have been trough my network who have seen that im just the type of guy who works my ass off to make dreams come true. I find events where you pitch to investors a little bit to over crowded with desperate entrepreneurs, and not serious investors Would totally reccomend entrepreneurs to build a network in the investment communicty and work super hard, then people will notice and investors will contact you, not you them.
