Trello was created in 2011 by Fog Creek Software founders and was spun out in 2014 with funding from Index Ventures and Spark Capital. It's a simple, visual project management tool for organizing tasks on boards.

Trello uses Kanban-style boards where teams organize work through an intuitive drag-and-drop interface. Cards represent tasks and can include details, attachments, due dates, and checklists. Users can customize columns, add Power-Ups for additional functionality, and integrate with external tools. The platform supports team collaboration with workspace management and permission controls.
