More recently we've been rejected three times with Missive, (https://missiveapp.com), still not financially successful, but starting to receive a pretty good vibe from early users + big potential.
I wrote about how we manage the two projects side by side with a small team of 4. https://medium.com/missive-app/successfully-bootstrapped-a-p...
Everyone is biased towards themselves, but still, I think we're a high quality, high achievers team that should have been accepted. You can now troll :).
We will reapply until we are in or until it doesn't make sense anymore. The value proposition of YC is that good + life is an adventure.
