We place insights at the heart of our work.
"Her experience and industry nous will be invaluable in delivering best in class solutions and strengthening our offering."
Nuckey added: "I am excited to be working with Allan and the Momentum UK team to lead our proprietary research efforts and strategic thinking in the UK for our wide variety of clients, starting with our next research piece, ‘We Know Sports Fans’, due for release in the June."
