Flock is a messaging app that allows you to chat with colleagues and entire teams. We make it easy for you to collaborate with people you love, wherever they are, and whatever they’re doing.

Whether you’re at home or at your desk, Flock is a powerful business communication tool that brings all your work into one place. You can share files and collaborate on projects and to-do lists with your team, regardless of where they are in the world.

The Flock team is made up of people who love talking to each other and working together. We believe that the best teams have a common understanding of where they’re going and how they’re doing it.
