Introducing the Fifth Seat

Global Chairman & CEO Jack Martin explains the Fifth Seat:


H+K’s overriding beliefs about business are set forth in the trademarked Fifth Seat, pioneered by Chairman and CEO Jack Martin. This model defines and drives H+K’s work for C-suite clients around the world. Basic tenets of the Fifth Seat:

CEOs and their boards have traditionally turned to four key advisors when weighing decisions: lawyers (for legal implications), investment bankers (financial impact), management consultants (internal ramifications), and accountants (balance sheet considerations).

Fifth SeatNone of these four “seats” focus on the public as a discrete consideration. And yet, the public ultimately decides which businesses succeed — or fail — and at what pace.

H+K proudly occupies the fifth seat in the room – the one devoted expressly to all matters that concern the public. The Fifth Seat advisory model combines human and research-based insights and tools with a deep trove of creative ideation to provide C-suites with the frameworks they need to grow public trust into corporate success.
