Posit: there hasn’t been a sustained break out social app not funded by a big tech company since Snap?

What candidates come to mind from each of the following buckets?

1. Funded by big tech and sustained
2. Not big tech funded, fizzled out

What social apps are you excited about? 

What do you think has the most promise to break out that fits your original criteria?

Would count tiktok as 1

For 2 I think of clubhouse, dispo, poparazzi etc

1. I think Youtube is the deepest sustained impact
2. maybe not of its own making, but Vine was pretty impressive, all things considered.

Do you think that Retro is gonna make it?
