RealtimeBoard, the online whiteboard that became Miro.
An online whiteboard still listed as RealtimeBoard in July 2019, four months after it renamed itself Miro; Miro raised $400 million at a $17.5 billion valuation in 2022 and now says more than 100 million people use it.
RealtimeBoard's Stompstart page called it "the simplest collaboration tool for project leaders, marketers, designers, developers and creatives." It was "an endless flexible space": a whiteboard for jotting down ideas, or a place for a team to build a whole project remotely, with mockups, post-it notes, feedback and video chat, and every change visible to everyone at once. The listing placed the company in Las Vegas.
When the Wayback Machine captured that page in July 2019, the name on it was already out of date. In a post dated 7 March 2019, founder and chief executive Andrey Khusid had announced: "As of March 6, 2019, we have a new name and brand identity: RealtimeBoard is now called Miro." The product had more than 2 million users, he wrote, and a new address at miro.com; the company had wanted a name that was memorable and easy to pronounce and spell.
Miro's About page traces the product to 2011, when Khusid needed a way for his design agency to show ideas to clients who were not in the same room. In January 2022 the company announced a $400 million Series C at a $17.5 billion valuation, bringing its total raised to $476 million. It said its users had grown from 5 million at its Series B in April 2020 to 30 million, and gave its headquarters as San Francisco and Amsterdam.
The old realtimeboard.com address forwards to miro.com, which now presents an AI-assisted visual workspace and says more than 100 million people collaborate on Miro across more than 250,000 companies.
