Dubai-based communications agency North Seventy Five has appointed Mustapha Al-Tayech as Associate Director, with responsibility for sustainability, energy and financial communications across the Middle East.Al-Tayech joins North Seventy Five from Burson, where he spent more than 12 years advising organisations including the Dubai International Financial Centre (DIFC) and Saudi Aramco.During his tenure at Burson, he worked across mandates covering financial-centre growth and investment, energy transition, major destination and infrastructure projects, and reputation-critical issues.In his new role, Al-Tayech will focus on strengthening North Seventy Five’s work across finance, energy and sustainability, while supporting the agency’s growth in the region.“I spent more than a decade working alongside Lisa and Iman, so there is already a great deal of trust and familiarity between us,” said Al-Tayech. “What made North Seventy Five particularly exciting was the opportunity to bring that shared experience into something newer and more entrepreneurial, whilst staying close to the kind of complex, high-stakes work I’ve always enjoyed.”Lisa Welsh, Co-founder and Managing Partner, North Seventy Five, said Al-Tayech’s appointment comes as clients increasingly expand into sectors including sustainability, energy, real estate and finance.“Mustapha has spent over a decade advising some of the region’s most influential organisations through the moments that matter most, and that depth of experience makes him a natural fit for North Seventy Five,” Welsh said.
