Inner Circle is an exclusive lifestyle community in Vienna, running adults-only events at discreet locations for a verified, closed membership. Its own summary of what it is built around is comfort: every rule and every step of the process, it says, exists so that guests feel safe, at ease and welcome.

Three things follow from that and the community states them plainly. Membership is closed — profiles and photographs only become visible once you have attended in person. Verification is personal rather than automatic. And a gender balance is guaranteed at every event, with the ratio published on each one, along with a maximum number of guests, an age range and the level of play the night is set at.

It also runs a matching feature of its own, Circle Match, and keeps its formats deliberately separate — in its own words, three clearly distinct worlds.
