Rovio also said all shareholders combined, which include such firms as Atomico and Accel Partners as well as Trema, would sell 34.3 million shares. That could be worth as much as $470 million. Thanks to the worldwide sensation of Angry Birds, Rovio has become one of the hottest gaming properties on the planet. The ability to milk that hit seemed to hit a wall in 2014. In December of that year, the company fired 110 employees and closed one of its game development studios to stem the bleeding. But the company has been on a bit of a comeback this year, thanks to new games and and a hit animated film based on its Angry Birds franchise. Rovio's revenues almost doubled the first six months of 2017, compared to the same period in 2016. In 2016, revenue jumped more than 30 percent over 2015. That's all good new for Kaj Hed, who was essential to the creation of Rovio. The company's cofounders include Niklas Hed, his cousin Mikael Hed, Kim Diker, and Jarno Väkeväinen.
