About
Trello is a visual project management and productivity platform — operating as a product of Atlassian Corporation (NASDAQ: TEAM) since its $425 million acquisition in January 2017 — providing kanban board-based task organization to over 50 million users worldwide through its boards, lists, and cards interface that applies the Kanban methodology to individual and team project tracking. Founded in 2011 by Joel Spolsky and Michael Pryor as part of Fog Creek Software (alongside Stack Overflow), Trello launched at TechCrunch Disrupt and reached 100,000 users within six weeks. Trello spun off as an independent company in 2014, raised $10.3 million in Series A from Spark Capital and Index Ventures, and was acquired by Atlassian for $425 million — the largest acquisition in Atlassian's history at the time. In May 2025, Trello launched a major platform update introducing AI-powered task extraction (automatically creating cards from conversations and documents), Trello Inbox (collecting to-dos from Slack, Microsoft Teams, and email), Trello Planner (calendar integration for deadline management), and Mirror Cards (synchronizing tasks across multiple boards).
