ExeLate, a web based advertising startup from Israel, provides users with something called the 'exeLate Targeting eXchange' which relies on Delayed ads. Delayed ads are set up as users visit vertical-specific sites (such as travel, shopping, cars, etc.) or do searches on a certain subject. Rather than directly triggering a relevant ad, ExeLate introduces a Delayed ad cookie; later on when any Partner Network has available ad space, they'll ID the Delay cookie and display a pertinent delayed ad. ExeLate does not however, collect personal info, they don't send out ads based on adult content, and they do not do behavioral targeting.
