M.io, formerly known as Message.io, announced the closing of a $5.75 million funding round today. The round was led by Goldcrest Capital, Eniac Ventures, and Two Sigma Ventures.

M.io is a universal messaging network that makes it easy to chat with anyone, regardless of which chat app they use. Users of popular apps like Slack, Cisco Spark, and Atlassian Stride can natively send each other direct messages and join universal channels.
