Along the way we learned a lot about why YC is important, what it does for you (and what it doesn't) and why the application process is one of the best ways to think through creating your startup.
We've been really lucky to have great alumni help advise us and give us feedback on our applications (yes, all of six of them, thanks Jason Freedman!).
So hit me up if you want me to look over anything, it's the least I can do: hello@sandersak.com
EDIT - I may be slow on the reply until after demo day ;)
