Gen Kobayashi, group chief strategy officer at M&C Saatchi Group UK, is leaving after little over a year — a fresh jolt of senior churn as the agency group pushes through its turnaround.
A senior exit at a group in transition
M&C Saatchi Group UK has confirmed that Gen Kobayashi, its group chief strategy officer, is departing. He joined in 2025 to lead strategy across the UK group, and his exit was reported by Campaign on 7 August.
The move lands while M&C Saatchi is still working through a multi-year turnaround after the takeover interest and boardroom upheaval of recent years. Strategy leadership sits close to the heart of that reinvention, which is why the departure matters well beyond a single name on an org chart.
Why strategy chiefs are the canary in the agency coal mine
In a holding-company world obsessed with AI, media and margins, the chief strategy officer is the role that decides whether an agency still has a genuine point of view — or is just an execution shop. Losing one mid-transformation is a signal worth reading.
The UK has seen a steady run of senior strategy and marketing moves across agencies this year, from VML naming a new CMO to reshuffles at the big networks. Talent is voting with its feet, and the agencies that keep their thinkers are the ones clients trust with the brief that actually matters.
What it means for M&C Saatchi's clients
For clients, continuity of strategic thinking is the real currency. A CSO exit raises a fair question: who now owns the through-line on the brands Kobayashi's team helped shape, and does the point of view survive the person?
Our read: expect M&C Saatchi to move quickly to reassure clients and, most likely, to fold strategy more tightly into its creative and data offer rather than replace like-for-like. The direction of travel across adland is blended strategy-plus-data leadership, not standalone planning departments.
The lesson for marketers
If your agency loses a key strategist, don't wait to discover what it means for your account. Ask who is picking up your business, what changes day to day, and whether the thinking behind your brand is written down anywhere.
Inside your own team, treat strategy as a capability you own, not one you rent. Document the logic behind your positioning so it survives the departure of any single person — on your side or your agency's.
