Dimdim

Open-source Web conferencing provider Dimdim has raised $6 million in Series B funding, the company is set to announce on Wednesday.

The funding round, which was led by current investors Index Ventures, Nexus India Capital, and Draper Richards, will enable Dimdim to introduce enhancements to the free service and expand its market reach.

Dimdim competes with fee-based services like Webex. Because it is open source, it could become a platform for real-time communications if it garners enough developer support.
Since its private launch 10 months ago, Boston-based Dimdim has attracted more than 500,000 users in more than 180 countries, the company says.
