There is nothing particularly subtle about the sales patter. "We make mutually beneficial relationships," goes one pitch. "We are where the attractive meet the affluent," claims another.
A third bills itself: "An upscale community of beautiful women seeking wealthy men."
The service being brokered is as old as the institution of arranged marriage. The pitches are aimed at wealthy male "sugar daddies" who, in the jargon of lonely hearts ads, WLTM [would like to meet] very much younger women.
In America's booming online dating market, few sectors are hotter than so-called "sugar daddy" sites, which help rich men to make "arrangements" with attractive and financially needy younger women. Between them, these specialist sites now account for 10 per cent of the entire industry. In the US the online dating business now generates profits estimated at US$700 million ($840 million) a year.
The "sugar daddy" trend began in 2006, when the entrepreneur Brandon Lee founded a website called SeekingArrangement. The older, male subscribers pay a fee of US$50 per month; young women can join for free.
