About Dopplr

Dopplr is a service for smart travellers. Dopplr members share personal and business travel plans privately with their networks, and exchange tips on places to stay, eat and explore in cities around the world.

Lisa Sounio, Tyler Brûlé and Saul Klein serve on the Board of Directors. Dopplr is backed by a premier international group of investors including Reid Hoffman, Esther Dyson, Thomas Glocer, Martin Varsavsky, Lars Hinrichs, Joichi Ito, Tyler Brûlé, and Saul Klein.
