Hey, this is Anth from Zumper. Interesting - yeah, it seems to work both ways. Big, well-known funds usually have the firepower to follow on, but that virtue can also be a vice if they don't and they scare everyone else off with that signal. This is my first startup so I can't comment with experience on going the angel route first to avoid these issues, but more and more founders seem to be going this route, and in part relying on their angels to make the Series A intros later on. AngelList itself seems to be thriving off this model.
