· Group transition enables greater integration and scalability
· Restructure sharpens focus and supports continued expansion
· New leadership team to drive Strata’s next phase of growth
Strata, the award-winning brand experience agency, has announced a major leadership restructure to support its continued expansion and ambitious growth plans within the events and experiential marketing sector.
This marks a formal leadership shift as Simon Hambley and senior colleagues transition to group-level roles focused on strategic growth across the wider agency portfolio. Day-to-day leadership of Strata will now be led by a new executive team comprising Cole Mulkerrins as Chief Executive Officer, Andrea Bishop as Managing Director and Giles Cattle as Chief Growth Officer.
Simon Hambley, formerly CEO of Strata, now serves as Group CEO, a move that reflects the business’s evolution and its goal of accelerating growth across its group of agencies. He will focus on shaping overall strategic direction, performance and integration across the group’s brands, working closely with recently appointed Non-Executive Chairman John Farrell and leveraging support from investment partners at Ethos.
Joining Hambley at group level are Paul Querfurth (Chief M&A, Integration and Transformation Officer), Phil Staines (Chief of Staff), Jake Shuckburgh (Chief People Officer), Julie Phillips (Finance Director) and Liz Gear (Head of Business Systems). Together with Farrell, this expanded leadership team will drive the group’s long-term strategy, integration efforts and operational excellence.
The new Strata executive team brings deep experience and continuity, having all held long-standing leadership roles within the business. Their appointments reflect the agency’s commitment to strengthening leadership from within and building a future-ready structure capable of scaling with continued demand.
“This transition signals our intent to grow further and meet the evolving needs of our clients,” said Cole Mulkerrins, CEO of Strata. “I’m incredibly proud to step into the role at such an exciting point in Strata’s journey. We’ve achieved strong momentum, built a brilliant team and delivered outstanding work. I’m looking forward to leading the business into its next phase and continuing to raise the bar across everything we do.”
This leadership evolution ensures Strata is well-positioned to deliver exceptional client work while exploring new opportunities for innovation, integration and group-wide collaboration.
