The four steps to epiphany was a pretty great book for me.

I'd agree. However, reading it is hard, really skim parts and come back to it over time. It's also where the Lean Startup started.

Yep. It's the first book I'd recommend to a technical founder without a business background. It's an amazingly useful book, even if the formatting / etc. leave a little something to be desired.
