Opinium Brings in Millward Brown's McCallum

London-based Opinium has hired Adrian McCallum, previously a Senior Director at Kantar Millward Brown, in the role of Research Director.

McCallum (pictured) spent sixteen years at Millward Brown and predecessor agency BPRI, and ten years before that in other b2b research roles. He has worked in sectors including finance, technology and professional services.

Opinium CEO James Endersby comments: 'We're growing at an incredible rate and making a number of high profile senior hires to support our existing and future clients. I'm over the moon that Adrian has chosen Opinium for his next big move after a hugely successful sixteen years at Kantar. Adrian is a phenomenal researcher and consultant and we're looking forward to working with him and welcoming him into the Opinium family'.

Opinium was founded in 2007 and is known for its political polling, having produced the only accurate eve-of-poll estimate for the EU referendum in 2016, among other achievements. A Manhattan office announced earlier this year, is due to open in December.
