In this landmark episode, Craig interviews Justin Gehtland and Rich Hickey as they discuss the merger of Relevance and Metadata Partners (the company behind Datomic) to form a new company: Cognitect. They discuss why they made the decision to join forces, what will stay the same with the products and services that Relevance and Rich currently provide, and what will be different and better. They discuss the choice of the name, and how it reflects the new company's philosophy of craftsmanship and considered design.

This is the final episode of ThinkRelevance: The Podcast; happily, it is also the first episode of The Cognicast.
