Trello

Trello is a web-based Kanban-style project management application, launched in 2011 by Fog Creek Software co-founders Joel Spolsky and Michael Pryor. Its card-and-board interface lets teams track tasks across customizable columns.

Atlassian acquired Trello in January 2017 for approximately $425 million, integrating it alongside Jira and Confluence. Trello now serves more than 50 million users worldwide across small teams, startups, and Fortune 500 companies.

As an Atlassian product, Trello does not report independent financial results. Atlassian (NASDAQ: TEAM) is led by co-CEOs Mike Cannon-Brookes and Scott Farquhar; day-to-day, Trello is managed as part of the Atlassian Work Management portfolio.
