Ask HN: Bootstrappers - How do you manage your product lifecyle?

I'm bootstrapping my web application, and while I have a non-technical cofounder, he is strictly business-oriented, which leaves the product management/direction, development, configuration/infrastructure, etc all on me. In previous jobs I was part of a team, where each of us had a discrete role (development, config mgmt, testing, etc.) How do others out there, that may be in a similar boat manage all of the moving pieces of getting your app up and out without going insane and ensuring critical things don't fall thru the cracks? Thanks for your time and assistance.
