Dopplr CEO Lisa Sounio announced that the online social service for frequent world travelers has secured early-stage funding.

The investors are Martin Varsavsky, Joichi Ito, Reid Hoffman and The Accelerator Group led by Saul Klein. This international team—frequent travellers who themselves use Dopplr—has separately made previous investments in many successful startups that reads like a who’s who of the 2.0 economy including, Last.fm, Joost, FON, LinkedIn, Flickr, Technorati, Wikia, Xing, Stardoll, Six Apart and Netvibes.

Dopplr lets you share your future travel plans with a group of trusted fellow travelers via an invitation system. It also reminds you of friends and colleagues who live in the cities you’re planning to visit. For example, Dopplr might tell you that three of your trusted friends and colleagues will be in Barcelona when you are there next.

Personally, I love the service and have been using it since Stowe Boyd invited me to join several months ago. I look forward to what’s next.
