Our conversation with GV's Jake Knapp + John Zeratsky was packed with so much goodness that we bring you an extra special, slightly longer episode this week. Their book, "Sprint" (www.gv.com/sprint), gives teams a process for answering critical business questions through design, prototyping, and testing ideas.

Also on tap: SB50 (we prefer Superbowl L), opinionated products, Land Rovers and Grove Labs.
