Los Angeles-based BlackLine Systems, the developer of financial close software used by companies to automate balance sheet reconciliation for companies, is in a major expansion, saying today that it has opened up offices in five cities worldwide. The company said it opened up offices in Atlanta, Chicago, London, New York City, and Portland, Oregon, on top of existing offices in Sydney and in Los Angeles. The firm said the new offices come as a result of international growth for the company. The firm said it saw revenues grow by 50 percent in 2010 and 2011, and expects a similar growth rate this year. BlackLine is headed by THerese Tucker.
