Creative wunderkind Ty Montague, along with a handful of others, have launched a new agency called :co. They're touted as 'a brand studio for the 21st century CMO & CEO.' :co develops business strategy, brand story, product innovation and new ventures, using a new model: flexible collaboration with a network of expert partners. With four core players, they've curated a group of 43 co-conspirators (thus far) – who are the best in the world at what they do. Interesting new-world model and one that looks primed to dominate.
