From the about us page:
We believe that a picture paints a thousand words. That is the reason why people use whiteboards to work with ideas, concepts and to explain them to the team and clients. But whiteboards have three serious drawbacks — you can’t save them, you can’t share them, they have physical limits.
RealtimeBoard is an endless online whiteboard where you can organize your workflow, brainstorm and manage your tasks in a highly visual way. Our team has designed these endless boards to give everyone – a person, a creative team or a huge company – an opportunity to collaborate on ideas and projects easily and freely from any part of the world.
RealtimeBoard is being developed by Realtimeboard Inc., a company based in Las Vegas, NV (USA).
