Considering using Brand Advocates to market professional financial services

This excerpt comes from Zuberance:

“Brand Advocates are people who frequently recommend brands and products without being paid. Brand Advocates are a company’s most engaged, loyal, and valuable customers.

Size: About one in four adults in the U.S. – about 60 million people – are Brand Advocates.
Influence: Advocates are about 3X more trusted and influential than ads and other forms of paid media.
Reach: Amplified by social media, Advocates’ recommendations reach now rivals ads.”

Is it possible or likely that Brand Advocates will change the marketing of professional financial services?
