A year later Exec got acquired and I started looking for another job. My roommate had failed an interview with Uber a few months earlier and gave me the recruiter's email. I sent an email, interviewed and got the job.
I've just started my own design/engineering studio with my fiancée - most of our clients have been our network so far. Either people we've directly worked with, or a referral from them.
So I think for me, it has always been about the network. That should be a pretty good news for anyone, because my network has never been very large (except maybe now that I cumulate experience both in YC companies and Uber).
