Trello is a free web-based project management application originally made by Fog Creek Software in 2011, that spun out to be its own company in 2014. It operates a freemium business model, as well as being cross-subsidized by other Fog Creek Software products.
A brief history of Trello. Around the summer of 2010, Fog Creek Software starts doing regular Creek Weeks, internal explorations for potential products. In January 2011, a prototype that hopes to solve some high-level planning issues is pitched. Itâs called Trellis. Full time development begins soon after.
