If you remember Flipboard, Evan Doll was in the iOS team and also taught the CS183 at Stanford. As per his LinkedIn as soon as he left, the same month he cofounded Flipboard although the app was released 1 year later.
I have a few coworkers from my team that cofounded companies and they too have 1-2 month gap after they quit and they all got funding :)
