As someone who has both founded a startup (and failed), as well as took 18 months to go overlanding -- and who now has a normal engineering job -- I found that interviewers were more impressed with the travel than the startup. The co-founder label still has some sort of negative connotation with certain interviewers. It seemed worse the larger the company was. I had no problem finding my pick of companies to work for however. The transition wasn't tough necessarily, but neither is the desk job very fulfilling. There's a sort of manifest destiny when you're building YOUR thing, and building anyone else's thing is just nowhere near the same -- regardless of the token scraps of RDUs or options or company outings they throw at ya. You're riding on the bus, not driving it. It just ain't the same. Like the other poster, I would do it all over again as well.
