I'd point you to two posts, the first is about a role I call "Everything But Code" http://jonsteinberg.com/post/67043520/everything-but-code

The second is an extension of the idea, which I call Hackable Business Development. http://jonsteinberg.com/post/170568831/hackable-business-dev...

You can also handle a lot of the product management and the interfacing and deals that can be built upon your API and those of prospective partners
