Nick Stanhope is the CEO of Big Problems, a company that takes a traditional approach to social and environmental issues by using messages, calls to action, and campaigns to encourage behaviors and target audiences. However, their new approach focuses on creating tangible products and tools that facilitate behavior change in a practical and desirable way to address issues like inter-generational dislocation. One such product is Historypin, a website that allows users to pin historical photos to maps and share them.
