Mainframe Industries has raised €20.3 million ($23 million) in funding to create a cloud-native MMO.

The funding round was led by American venture capital firm Andreessen Horowitz, marking the company's second investment in Mainframe since the studio was established in April 2019.

The cash injection also brings notable co-investors Kevin Lin and Riccardo Zacconi into the fold. Lin is best known as the co-founder and former COO of Twitch, while Zacconi co-founded and prevously led King as CEO.

Mainframe, which describes itself as a "pan-European studio," said the cash will allow it to realize its vision of creating a "persistent living world that people will call their home for years and hopefully decades."

"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," added Mainframe CEO, Thor Gunnarsson.

Mainframe is also working to expand its presence in Helsinki, Reykjavik, and Paris, and said its unnamed MMO will be a "social sandbox" that's playable across mobile, PC, and console platforms.
