Tony White

In recent years, Monaghan-born Tony White has been better known for his Manhattan property deals than the direct marketing from which he originally made his fortune. After emigrating to the US, he set up Abacus Direct in 1990, floating it seven years later on the Nasdaq. Two years later, he netted €63m in stock when he sold the business to internet ad broker DoubleClick for €1.05bn.

But since then, he and his wife Clare have been behind some very high profile - and lucrative - home sales. They sold the famous Upper East Side Mellon mansion in 2015 for $37m, having bought the home for $22.5m in 2006. That same year, the couple sold a home across the street, at 118 E 70th St, to Woody Allen for $25.6m, having bought it in 1998 for $6.05m.
