In 1993, Terry Zmrhal and Geoff Cashman were the originators of this service. In 1996, Roger Gravel began updating and managing the Warm Showers List after he found that it hadn't been maintained. Randy Fay turned the list into a database-and-map enabled website in 2005 and eventually assumed the webmaster/registar role from Roger when Roger retired in 2009. Now a small but dedicated group of volunteers manage the site and communication with our members.
The growth of the membership and its worldwide distribution are shown on the Statistics page.
In recent years the Warmshowers.org Foundation was formed to improve governance and sustainability of the organization. It is now a US 501(c)(3) nonprofit corporation. It has a Board of Directors and all decisions and financial reports and similar information are posted in the Leadership Council section of the forums.
