If you're stuck behind a firewall at work, you are probably familiar with Meebo.
Apparently enough people are familiar with the instant messaging system that Meebo has opened a new office in San Francisco.
The company currently has offices in Mountain View but it has raised $70 million in venture capital funding in six years and its staff has expanded.
Meebo's new San Francisco location will be home to about 50 employees at 101 Montgomery St.
The company is not done expanding there either. A spokeswoman told the San Francisco Business Times that Meebo plans to expand its staff across all departments by 25 percent by the end of th year.
