Power, who joins the company from RDSi, where he is a board level director, takes up the new role from November. He has previously held client-side roles at Hachette and Future Publishing.

Reporting to Matilda Andersson, the company’s London managing director, Power will manage the quantitative and analytics team, directing the team’s services across Crowd DNA offices in London, Amsterdam, New York, Singapore and Sydney.

Crowd DNA’s quantitative and analytics offer provides around a quarter of the company’s revenue.

Under the new brand, Crowd Numbers will continue to offer online surveys, but will add passive tracking, data synthesis and social learning.

Andy Crysell, group managing director, Crowd DNA, said: “This is about giving data and quantitative work a louder voice in our business. With David on board, we’re excited by the potential we have to apply more of a data-led perspective to our ambition of providing our clients with culturally charged commercial advantage."
