Meebo, a site where users can access all of their instant messaging applications in a single browser window, is announcing a $9 million Series B round of financing from Draper Fisher Jurvetson this evening, adding to the $3.5 million they raised from Sequoia in December 2005. As part of the round, Tim Draper is joining Meebo’s board of directors.

Our first post on Meebo was written the day it launched in September 2005. Since then we’ve watched them grow significantly (see our coverage here).

Meebo competitors include eBuddy, KoolIM and others listed here.
