For the latest episode of my Foundation series, I headed over to the Path office to sit down with founder Dave Morin. Dave talks about getting his start in student marketing at Apple, and reflects that focus is one of the most important things he learned there. He goes on to describe his time at Facebook, where an intense focus on product utility set the product up for long-term growth. Dave also dives into the moments that inspired Path, and the different ways their team thinks about the social graph.
