Framebench

Framebench is a cloud-based real-time collaboration platform with a focus on real-time communication, collaboration, and sync. Users have to upload files (doc and images) on to their platform. These files can then be viewed by the whole team and can be discussed upon using voice or chat. Its TableTop sync allows users to play, pan, pause, zoom and edit any file. Also allows collaboration on videos. Has 1,250 users as of February 2013. Available in a free plan and a paid ($19) plan. Acquired by Freshworks.
