MillionaireVue, which currently operates in the UK, US and China, will now also include France, Germany, Italy, Spain, Switzerland and the Netherlands.

The survey currently gathers data from more than 500 validated millionaires across the UK, the US and China, with an additional 350 validated millionaires being covered across Europe.

MillionaireVue aims to provide luxury brands with insight on market intelligence, audience understanding, brand and marketing performance, customer acquisitions and customer retention.

David Barks, senior director, wealth – financial services at Savanta, said: “Expanding our omnibus survey into Europe is an exciting opportunity to further help brands obtain data quickly and cost effectively in six additional markets as we continue to grow our offer.”
