Hey! I run marketing for Periscope Data, a data explorer/dashboard product. We have a lot of customers using postgres and get compared to Looker a lot. We focus on optimizing for the analyst whereas tools like Looker focus on business users. We have a lot of features for business users, but chart creation is all SQL based.
