Out of the 2 cofounders in YC, one I later hired to run network operations at my company and the other I am very close friends with and regularly have beers. We left on good terms. Why don't you ask the two of them what they think of me?
You're the reason why I'm an entrepreneur today and I respect you immensely. To hear you describe what I did as treachery is hurtful but worse it's just factually wrong. It was an incredibly difficult ethical decision for me at the time, but I truly believe that I behaved in a transparent and above the board way.
I take responsibility for not talking to you before or after I left - I didn't realize you felt this way about it and I'm happy to have the chance to bring this out into the open.
