CK is by invitation only, but based on more than spend. It's really based on
ability to influence spend. So, for example, it's a safe bet that the travel managers for the Fortune 100 are probably all CK because they set the travel policies for their organizations. But spending a ton as a individual doesn't necessarily get you a CK invitation.
