Big Fish Games has rehired founder Paul Thelen as CEO, who left to be managing director at Goldman Sachs in 2006. Current CEO Paul Lewis, who was promoted to the position in 2008, will step down from the position but will continue on as a director at the company .

“This is a natural point in our company’s progression for me to pass the responsibilities as President and CEO back to Paul, who at this stage is best suited to lead us forward,” said Lewis in a company memo. “He will bring his characteristic entrepreneurial drive and creativity to the forefront.”

Big Fish had sales of $180 million in 2011, up 30 percent year-on-year. With dividends paid to its shareholders and almost every employee in October, it is believed that the company will go public soon.
