One of the first tasks I tackled at Marketo was identifying and creating personas of the various users and influencers using the product. It’s an essential part of product development — making sure everyone agrees on who the customers are, what their goals are, and who the product is targeted at.
At the insistence of my boss, we made the personas a little bit silly so that they would be more memorable and interesting. You can see the results below. The way we knew it was successful was that during our product discussions we would refer to the personas by name.
