Paananen, Kodisoja, Petri Styrman, Lassi Leppinen, Visa Forstén, and Niko Derome who had known each other through work connections, founded Supercell in 2010. The company started its business in the Niittykumpu district of Espoo. Kodisoja and Paananen invested €250,000 in the company. Tekes, the Finnish funding agency for technology innovation loaned them a further €400,000 and Lifeline Ventures also invested in Supercell. The following October, Supercell raised €750,000 through seed funding, including from London Venture Partners and Initial Capital. The first game Supercell started to develop was the massive multiplayer online game Gunshine that could be played on Facebook with a browser or on mobile platforms. The game prototype was ready in eight months. After Gunshine's completion, Accel Partners also invested €8 million in the company in May 2011, and shareholder Kevin Comolli became a member of Supercell's board of directors. Accel also invested in Rovio, among others. Change of strategies In November 2011, Supercell abandoned Gunshine for three reasons: it did not interest players for long enough, it was too difficult to play, and the mobile version did not work as well as the browser version. At best, the game had approximately half a million players. Supercell considered Zynga's market leadership in games on the Facebook platform insurmountable and so decided to focus on iPad games, cancelling a Facebook game it was developing. In order to ease concerns of Supercell's investors due to the change of direction, Paananen increased the detail of progress reports. The company simultaneously developed five games and the first to be released for public testing was Pets vs Orcs. This game and Tower were abandoned. In May 2012, Hay Day was published and eventually became Supercell's first internationally released game. Hay Day was Supercell's version of Zynga's successful Facebook game FarmVille, an easy-to-play farm simulator. Supercell added to their farming simulator the ability to refine products, a production chain, and touch screen properties. The social aspect of the game was emphasised as well. In four months, the game became one of the most profitable games in Apple's App Store in the US, and was one of the most profitable in the world for two and a half years. The game receives regular updates and is maintained by a team of 14 people. Development of Clash of Clans Lasse Louhento had started at Bloodhouse, and Lassi Leppinen was the chief programmer at Sumea and Digital Chocolate.
