Trello is free forever. We may add pay-only features in the future, but everything that's free today will be free tomorrow and forever. Also, we'll not make a for-pay feature that forces you to compromise on privacy, security, or portability. Those are built-in.
How does Trello make money?
You might wonder what's supporting Trello's development. We want our users to know that Trello has a firm foundation and is well funded. Trello is here to stay.
Trello is the product of Fog Creek Software, a small, profitable, and friendly software company based in New York City. We make other products, FogBugz and Kiln, which pay for their own development plus the development and hosting costs of Trello, with more than enough left over for lunch.
Fog Creek is a sustainable and profitable business. We do not have outside investors pushing us to make money from Trello before we know what it’s going to be. Ultimately, we’d like Trello to be a self-sustaining and profitable product in its own right. When we turn our attention to profitability, we expect to follow the ideals that have made us successful for the last decade: respect for the user, excellent customer service, integrity in business, and making profits by providing real value.
We recently launched Trello Business Class, which provides additional tools to help make managing an organization a bit easier. This is a paid product (yay!).
Trello Gold is designed to give individuals additional features that aren't essential to the core Trello experience. It's a way to support Trello while getting a little something in return.
