What is the name of Discord's other co-founder besides Jason Citron?

Discord’s other co-founder besides Jason Citron is Stanislav Vishnevskiy. He became Discord’s chief technology officer and helped shape the technical architecture behind the service.

Before Discord, Citron had founded OpenFeint, a social gaming network, and later created the game studio Hammer & Chisel. Vishnevskiy had founded Guildwork, a social platform for gamers. Their experience with online communities and the communication problems faced by multiplayer teams helped lead to Discord’s creation.

Discord began as a response to the difficulty of coordinating in games such as Final Fantasy XIV and League of Legends. The service was publicly released in May 2015 and combined low-latency voice communication with text channels and persistent communities. Vishnevskiy is also closely associated with Discord’s early adoption of Elixir for highly concurrent, real-time systems. His name is sometimes shortened to “Stan Vishnevskiy,” but that refers to the same co-founder.
