DIY, mostly. The first one that was truly my own I did by starting a dev-for-hire/consulting company and stashing some of the proceeds on the side to fund development of my first startup, and then from there it's self-sustaining. For passing the baton to the right people, finding those people is partially luck to begin with and basic networking, but after awhile you know a good group of people that you've worked with in the past (or are friends of them). More than once I've handed things off to some of the same people - I'm ready to leave this gig right as they are ready to leave the prior one.
