Read Rocket Fuel. Its a book I am sure the HN crowd will critique but it has made a large difference in how my biz operates and how multiple founders fill roles. I am very much an "integrator" from the book. I am less of the massive, big picture and more of the day to day execution. Good at growth/maintenance. Not great as a true "founder". And I have managed through near death and it seemingly took years off my life so I'd prefer not to go back to that one!
