Overview
Mainframe Industries is a Helsinki-based game development studio building cloud-native massively multiplayer online games designed to run across devices via streaming. Founded by veterans from Riot Games, Remedy, and EA, the studio raised approximately $8.3M Series A in 2020 and ~$23M Series B in November 2021, both led by Andreessen Horowitz, with Play Ventures and others participating.
Why Mainframe Industries is interesting
Mainframe is among the first studios designing MMOs explicitly for cloud gaming — a16z led Series A and B (~$31M total) as Riot Games and Twitch alumni bet on device-agnostic persistent worlds.
Product & use cases
Mainframe develops PIONGG — a cloud-native MMO framework and game built for streaming to phones, tablets, and PCs without separate platform ports. Architecture assumes cloud infrastructure from day one rather than retrofitting console/PC titles.
- Players accessing persistent MMO worlds on mobile without native app performance constraints
- Cross-device progression in a single MMO account via cloud streaming
- Studios licensing cloud-native multiplayer infrastructure learnings

Competitive landscape
Edge: Finnish AAA talent (Remedy, Riot alumni) plus a16z double-led rounds gave runway to build for cloud-first MMO before competitors ported legacy engines.
Cloud gaming MMOs remain unproven at scale — latency and economics hurt. Mainframe's bet is native cloud architecture unlocks MMO experiences impossible on mobile hardware alone.
-
Traditional MMO studios (Blizzard, etc.) incumbent
PC/console-first MMOs porting to mobile; Mainframe cloud-native from architecture level.
-
Xbox Cloud Gaming / GeForce NOW adjacent
Cloud streaming platforms; Mainframe builds games optimized for streaming vs streaming PC titles.
-
GaaS mobile MMOs direct
Native mobile MMOs; different technical approach than Mainframe's cloud streaming design.
Notable stories
- Mainframe's founders saw mobile MMO attempts fail on hardware limits — betting cloud streaming lets one world serve all devices if designed natively for cloud, not ported.
- a16z leading both Series A and B signaled long development horizon acceptance rare in mobile gaming VC.
