Dialog, the private network cofounded by Peter Thiel, grades its event attendees on a hidden scale, ranking them by wealth and fame, tracking their relationships, and using algorithms to help decide who they should meet, who they should sit with, and who no longer belongs. Founded in 2006 by Thiel and data broker Auren Hoffman, Dialog is a private club that convenes politicians, investors, entrepreneurs, military leaders, executives, academics, and journalists for invitation-only, off-the-record retreats. According to a Dialog document shared by a past participant, it has "over 1,000 paying members," and more than 2,500 people have attended its annual retreats. Dialog assigns people grades before they join. Of the 192 dossiers examined by WIRED, 130 are tagged as members. The rest are prospects with files bearing markings like "First Time Dialoger" or "Warm." Everyonemembers and prospective invitees alike"is assigned a grade of A, B, or C. The "C" grade appears reserved for the most famous and influential; only one in seven received it. Most people"141 of 192"received a "B." The final tier, "A," appears primarily assigned to older, established members whom the graders consider less notable. The leak also points to a built-in matchmaking system that pairs members for both networking and dating. (Roughly 10 percent of respondents opted into a singles pool.) More than three-quarters already have a list of algorithm-suggested matches.
