Australian software company Atlassian has agreed to acquire the Trello collaboration service for around $425 million.
Atlassian is the company behind Jira, Confluence and HipChat, which are used by more than 65,000 organisations in 170 countries.
Cloud collaboration service Trello's user base has almost doubled to 19 million in more than 100 countries over the past year.
It is used to organise and share information between teams in a diverse range of organisations including Fender Music, Google, John Deere, National Geographic, the Red Cross, the United Nations – and a cafe in Brazil.

"Atlassian knows more about how teams work than any company on the planet, which is why our collaboration suite powers teams of all shapes and sizes, from bleeding-edge startups to the Fortune 50," said Atlassian co-founder and co-CEO Mike Cannon-Brookes.
"There is no silver bullet for teamwork. Teams have diverse ways of working and require a broad set of tools that adapt to their specific needs. Trello has built an incredibly sticky and useful product for organising nearly any type of information simply and quickly. The addition of Trello will be a great complement to our existing portfolio of team collaboration software as we look to reach the 1 billion knowledge workers globally."
Atlassian will provide a new version of its Trello integration for HipChat, and will introduce Trello integrations for other products including Jira, Confluence and Bitbucket.
The current plan is for Trello to remain as a standalone service.
Trello chief executive Michael Pryor said: "We share Atlassian's mission of unleashing the power of all teams. As part of Atlassian, we will accelerate our efforts and continue to champion teams everywhere.
"Atlassian's deep investments in research and development will help augment Trello's product offering. And the broader team collaboration portfolio Trello will integrate with will let us help customers in new and exciting ways."
Atlassian will pay approximately $360 million in cash for Trello, with the balance in Atlassian restricted shares, restricted share units and options to acquire Atlassian shares.
The transaction is expected to close by the end of March 2017, subject to conditions and approvals.
