Finnish cloud games developer Mainframe Industries has scored €20.3 million (23 million) in investment.

This Series B funding round was led by Andreessen Horowitz, with the likes of Twitch co-founder Kevin Lin, the co-founder of King Riccardo Zacconi and Dreamhaven, as well as Riot Games, who had previously invested in the company, chipping in.

That €20.3 million includes a €3 million ($3.4 million) loan from Business Finland.

We’re creating a persistent living world that people will call their home for years and hopefully decades,” commented Thor Gunnarsson, CEO and co-founder at Mainframe. “With this formidable group of returning partners and new industry friends on board, we will field a world class team able to make our vision for the future of MMO games real, and open to gamers from any screen they choose to play on.”

Jonathan Lai, general partner at a16z and new member of Mainframe's board, added: “When we first met the team, we were impressed by a roster of talent inclusive of the original developers behind trail-blazing MMOs like EVE Online and Habbo Hotel. Mainframe's ongoing ability to attract stellar talent has been instrumental as they continue to innovate along many different dimensions, from gameplay to new distribution models to virtual economy design."
