Source code repository startup GitHub is looking to raise $200 million for a new funding round that could give the company a valuation of about $2 billion, according to a new report today.

When the company announced its enormous $100 million series A round from Andreessen Horowitz in July 2012, it had a $750 million valuation, according to today’s report from Bloomberg.

A GitHub spokesperson declined to comment.

GitHub has become the de facto online hub for developers to collaborate on open-source projects large and small, including Docker, Meteor, Node.js, and RethinkDB, to name a few prominent ones.

The company has been pushing hard to get companies to pay to run GitHub Enterprise so their engineers can keep repositories of code secure. In addition to its availability in on-premises data centers, GitHub Enterprise has become available on popular public clouds Amazon Web Services and Microsoft Azure.

And GitHub has been keen to make its service relevant for people other than coders. Last month GitHub announced support for Jupyter notebooks to help data scientists collaborate.

San Francisco-based GitHub started in 2008.
