Online network for frequent business travellers Dopplr has raised new funding from a group of angel investors in a second financing round. The undisclosed round makes the list of Dopplr backers even more impressive than it already was: Martin Varsavsky, Reid Hoffman and Joichi Ito were some of the initial seed investors, while Saul Klein from The Accelerator Group invested in both rounds.

Now you can add the following familiar names to that list: Esther Dyson, Tyler Brûlé, Thomas Glocer, Yat Siu,Aditya dev Sood, Lars Hinrichs, Joshua Schachter, Brian Behlendorf, Ami Hasan, Daniel Sachs, Joshua Cooper Ramo, Kim Weckström, and Azeem Azhar.

Dopplr helps you make the most of your trips by sharing your travel plans with people and brands you trust.

The service then highlights coincidences, for example, telling you that three people you know will be in Tokyo when you will be there too. You can use Dopplr on your PC or on the go, and links with many popular online calendars and social networks. 

Dopplr expects to use this new round of financing to expand its business globally. Currently, Dopplr’s user base is mostly in Europe and the U.S.
