Twitter Raises $80 Million From Andreessen Horowitz

Posted Feb 9, 2011

Twitter has raised $80 million from Andreessen Horowitz through stock in secondary markets. Andreessen Horowitz decided to make the investment since they are already major investors in other social companies like Zynga, Facebook, Groupon, and Foursquare. Twitter’s last round of funding was $200 million and a $3.75 billion valuation. [AllThingsD]
