Linear is fast, easy and carefully designed. Unlike other project management tools you are asked to work in a methodology which they have defined is best for software companies. Solved most of the problems of other PM tools.
They charge you the same amount for guests and that could be challenging if you are working with external parties.
Linear helps to streamline our dev and design teams. We create roadmaps, projects, and sprints and maintain our backlog of tasks in Linear. We also use it to handle support cases.
