Trello software

Trello is a prominent web-based, Kanban-style list-making application, widely used for project management and team collaboration. It was originally created by Fog Creek Software in 2011 and later spun out into its own company. The tool gained significant traction for its intuitive interface and visual approach to task organization, allowing users to move cards across boards to represent workflow stages.

In 2017, the brand was acquired by Atlassian, a global leader in software for teams. Trello continues to operate as a core part of the Atlassian ecosystem, often integrated with other tools like Jira and Confluence. While the service is available globally through cloud infrastructure, its primary development and corporate ownership remain centered in the United States and Australia, reflecting Atlassian's dual headquarters and multinational operations.
