We took a bet on Linear fairly early on (moved over last August!) and have been consistently impressed. I've used many different tools in the past (Pivotal Tracker, Jira, Trello, Asana, Github...) and Linear has by far the most polished, productive interface of the bunch.

We have fairly strong opinions about our workflow (using points, planning sprints, etc) and have found that even in the cases where Linear isn't as opinionated as we are, or doesn't have granular tools/configuration to manage things, we can get most of the benefits we need by using tags and other features appropriately. I was a die-hard Pivotal Tracker user before this, and it's very hard to imagine going back now.

Super impressive product and team, highly recommended!
