About us

Nabu Casa is best known as the organization driving the development of Home Assistant, the world's largest free and open-source smart home platform. More than one million households benefit from its home automation capabilities. Powered by a worldwide community of open-source developers, GitHub ranked it the second most active open-source project in the world in 2023.

We were initially founded to ensure that the development of Home Assistant would remain sustainable as it kept growing, but over time it has grown to support more open home initiatives. In 2024, the Open Home Foundation was formed to protect these open-source projects and ensure they thrive into the future. Nabu Casa is a commercial partner of the Foundation, and our principles are aligned with a joint commitment to privacy, choice, and sustainability in the smart home. These are the values that we put at the heart of every decision we make. It’s woven into our architecture, licensing, community, and everything else.

Nabu Casa is profitable, has no external investors, and our only funding comes from people subscribing to Home Assistant Cloud and buying Home Assistant hardware. That means the only stakeholders we have to concern ourselves with are our employees and our users. We now employ more than 30 contributors from all over the world to make sure they have the financial freedom to focus on Home Assistant and other open-source projects that help drive the Open Home vision.
