Percolate, a content-marketing platform used by some of the biggest brands in the world, it built a tool called Barista that allowed anyone in the company to ask a question and route it to people who might know the answer. Completed questions were tagged, saved, and searchable by everyone else. Instead of trying to drown a new employee in pushed information, Percolate let them find what they needed when they needed it.
