Trello

One of the most widely recognized and used visual project management tools globally, known for its simplicity and Kanban-based interface.

Trello is a widely adopted visual collaboration and project management platform that organizes work into an intuitive Kanban-style interface of boards, lists, and cards. Originally launched in 2011 by Fog Creek Software and later spun off as its own company, Trello enables individuals and teams to plan projects, assign tasks, set deadlines, and track progress in a highly visual and flexible way. Its simplicity and adaptability have made it one of the most popular productivity tools globally, with tens of millions of users across industries. Trello's platform supports a rich ecosystem of integrations and Power-Ups — add-ons that extend functionality with features like calendar views, automation, time tracking, and connections to third-party tools such as Slack, Google Drive, and GitHub. The product caters to a broad audience, from individual freelancers to large enterprise teams, offering both free and paid tiers. Its no-code automation engine, Butler, allows users to automate repetitive tasks without technical expertise. While Trello is not a core AdTech platform, it is widely used within marketing and advertising teams for campaign planning, content calendars, and workflow management. It competes in the broader project management and productivity software space against tools like Asana, Monday.com, Notion, and Jira. Trello's strength lies in its ease of use, visual clarity, and extensive customization options, making it a go-to choice for teams seeking lightweight but powerful task management.
