Who can join W3C?
All types of organizations (including commercial, educational and governmental entities), for-profit or not-for-profit, may join the World Wide Web Consortium. They may be developing web-based products, using web technologies as an enabling medium, conducting research on the web, or developing specifications based on W3C work.
W3C's processes are designed for organizational participation, and there isn't a class of Membership for individuals. Public participation in W3C is possible in a number of ways other than as an individual Member.
Membership fees
In order to promote a diverse Membership that represents the interests of organizations around the world, W3C Membership fees vary depending on the annual revenues, type, and location of headquarters of an organization.
