Fivetran, an Oakland, California-based data integration startup, is raising new funding that’ll value it at more than $1 billion, according to a report from Bloomberg. Fivetran, which last raised funding less than a year ago, is reported to be in advanced talks to raise even more funds from investors including venture capital firms General Catalyst and Andreessen Horowitz.

Fivetran’s most recent funding was a $44 million Series B round led by Andreessen Horowitz in September of last year. Other investors including Matrix Partners and CEAS Investments also participated in the funding. Martin Casado, a partner at Andreessen Horowitz, is notably a member of Fivetran’s board.

Since its founding in 2012, Fivetran has raised about $63 million in total funding. The company develops data analytics tools targeted at enterprises and currently has more than 1,000 paying enterprise customers.
