Trello is a web-based, Kanban-style, list-making application and is a subsidiary of Atlassian.[5] Originally created by Fog Creek Software in 2011, it was spun out to form the basis of a separate company in 2014[6][7] and later sold to Atlassian in January 2017.[8] The company is based in New York City.[9]


The name Trello is derived from the word "trellis" which had been a code name for the project at its early stages.[10] Trello was released at a TechCrunch event by Fog Creek founder Joel Spolsky.[11] Wired magazine named the application in September 2011 one of "The 7 Coolest Startups You Haven't Heard of Yet".[12] Lifehacker said "it makes project collaboration simple and kind of enjoyable".[13]

In 2014, it raised $10.3 million in funding from Index Ventures and Spark Capital.[14] In May 2016, Trello claimed it had more than 1.1 million daily active users and 14 million total signups.[15] On January 9, 2017, Atlassian announced its intent to acquire Trello for $425 million. The transaction was made with $360 million in cash, while the remaining $65 million was made with shares and options. Trello sold 22% of its shares to other investors with the remaining majority held by founders Michael Pryor and Joel Spolsky at the time of acquisition.[16][17]

In December 2018, Trello announced its acquisition of Butler, the company that developed a Power-Up for automating tasks within a Trello board.[18] As of March 2019, Trello was adopted by over 35 million users.[19] Shortly after, in October 2019, Trello announced 50 million users.[20]


Users can create their task boards with different columns and move the tasks between them.[21] Typically columns include task statuses such as To Do, In Progress, Done. The tool can be used for personal and business purposes including real estate management, software project management, school bulletin boards, lesson planning, accounting, web design, gaming, and law office case management.[22]


According to a Fog Creek blog post in January 2012, the client was an extremely thin web layer which downloads the main app, written in CoffeeScript and compiled to minified JavaScript, using Backbone.js[23] HTML5 .pushState() and the Mustache templating language.[24] The server side was built on top of MongoDB, Node.js and a modified version of[24]


On January 26, 2017, PC Magazine gave Trello a 3.5 / 5, calling it "flexible" and saying that "you can get rather creative", while noting that "it may require some experimentation to figure out how to best use it for your team and the workload you manage."[25]
