About Habitat X

Mission Statement: “The mission of Habitat X is to support the personal and professional development of individuals and organizations who work to develop sustainable housing.

The Broad Vision: “We recognize that housing, culture, and environment will be increasingly linked in the future, as limited financial and natural resources constrain our ability to house ourselves. We envision a next generation of sustainable housing, the creation of which could free important human and material resources for future generations. To this end, we create collaborative and fast-moving conferences and industry summits, on both face-to-face and virtual platforms, where people can connect with allied professionals in meaningful ways, expand their knowledge and skills, and become substantially more effective in their work.”

Habitat X, Inc. is organized as a Public Benefit Corporation (also known as a B-Corp) under the Montana Benefit Corporation Act, Title 35, Chapter 1, Part 14. Habitat X was founded by Chris Dorsi in 2011. The offices are located in Helena, Montana.
