Dimdim’s mission is to become the leading provider of open source web meeting software. Dimdim strives to be an open and transparent company, with source code, product roadmaps and simple technical documentation freely available online. We also listen closely to the needs of the open source community and are actively improving our product based on their feedback.

"...solutions that remain islands, developed and deployed by one company, are much less interesting
than open-source solutions that are developed and deployed by a community."
