How Do You Lead Your Company Through Massive Growth? Nathan Tells Us How He Did It: Founder & CEO, Nathan Pettyjohn, was shopping in a big box store and could not find the item he was looking for. So he started a company that helps businesses map their store so customers can have an awesome in store experience. Along the way he has learned some important lessons on leadership. I especially like the story he tells about how he recovered from a potentially devastating failure.
