Rovio Mobile, the firm behind the hit game Angry Birds, has set a goal to seek an initial public offering (IPO) sometime during the next 2-3 years, Reuters is reporting. The firm raised $42 million in Series A funding earlier this year, and its Angry Birds franchise has spread across multiple platforms including Android, iOS, webOS â€” and you can even play it in your web browser. As such, Rovio has increased its staff from 12 employees to 100 employees this year. “I see that this is only beneficial for us in terms of making the company more structured and more focused on creating it into a proper large organization, having grown from a company of 12,” Rovio’s CEO Mikael Hed said during the Reuters Global Technology Summit in Paris. In May, Rovio’s board chairman expressed interest in seeking an IPO in New York.
