There's no way they have 1MM DAU. People play that once and then leave.
There are lots of apps with 20+ million downloads (total), and if they're good apps they might be pushing 1MM DAUs (of course, tough to tell unless developer reveals that). All I'm saying is that some of them are hits and VC's are clamoring over, but some might be good lifestyle (or less scalable) businesses and VC's aren't "knocking over doors" to fund a Series A with them.
I'm just calling out the assumption that 1MM DAU = guaranteed Series A funding.
Come to think of it, I should retract what I said about most of them not being VC-fundable. I just don't know cause the stats aren't out there.
