thjnk Co-Founder Armin Jochum Quits to Run a Brand Client-Side

Armin Jochum, co-founder and CEO of Hamburg agency thjnk (part of WPP's Ogilvy Group Germany), is stepping down at the end of September to take over global brand management at a corporate from early 2027 - the latest marquee German creative to cross to the client side.
The Move
Armin Jochum, 58, co-founder and CEO of thjnk, is leaving at the end of the month to move client-side, taking on global brand leadership at a corporate from the start of next year. thjnk, which he co-founded in 2012 out of the former Kemper Trautmann agency, will install a team-based leadership from within rather than name a single successor.
It is a significant departure. Jochum is one of the most recognisable names in German advertising, and his exit to run a brand rather than an agency is a telling signal about where senior creative talent sees its future.
Why It Matters
In-house marketing is no longer just poaching agency talent by the individual; it is poaching agency leadership. When a co-founder chooses global brand management over running one of the country's best-known shops, it says the client side now offers the bigger canvas.
For agencies, that is a structural challenge. The traditional flow of ambition ran toward the agency world; increasingly it runs the other way, as brands build serious in-house creative capability and offer the scale and stability to match.
Marketing Minute's Take
We read this as more evidence that the agency-brand boundary is blurring from both directions. Brands are internalising creative leadership, and the best agency minds are following the work in-house. Neither side can take its talent pipeline for granted.
For brand owners, the opportunity is real but conditional: hiring senior agency leadership only pays if you give them the mandate, budget and creative freedom that made them good in the first place. Bring the talent in, then let it work - or you will simply have made an expensive hire who leaves.
