Doodle is a free web app which helps you find suitable dates for group events, like a conference call, by creating a poll for a suitable meeting time and lettting people fill in their availability. It’s an idea which works very well, and is easily messed up. London-based ikordo closed last year through lack of funding and a complex interface. However, Doodle, which grew from a hacker project, has well-funded competitors like Tungle , which also comes as an Outlook plugin and has $1.5m in backing, as well as TimeBridge , and Jiffle . So Zurich-based Doodle is hoping its Outlook plugin, generic calendar feeds, white-label version and – most importantly – new open API for developers will set it apart from the pack.
