I was in the same situation as you at the end of last year. After 2.5 years working on a Techstars VC funded startup as a co-founder, we failed. Unfortunately at the time, I didn't have the extra cash to take time off, so I sent a few emails out (to the Techstars network) and a few weeks later jumped onboard another early startup as the first engineering hire. I honestly wasn't sure if I wanted to join another early stage company, but they offered a nice salary (I obviously chose salary over equity), a nice bonus, + some equity. They were the perfect fit for me, so things worked out well.

If you have the $$ to travel before moving on, I would advise you to take some time off to relax and get your mind away from the startup world. Go see your family, it's amazing how much they care.

Lastly, you will experience many emotions for many months following, don't take it too hard. Life goes on, things happen for a reason, and good luck! It will all work out.
