Rare

Perth independent agency Rare promoted Simon Stewart to managing director, with Callum Mackenzie moving to executive chair.

Leadership read: Stewart's promotion is not a lateral reshuffle, it commits Rare to a defined succession structure in which the founder or long-tenure principal steps back from day-to-day operations while retaining strategic oversight. That separation of execution from ownership is operationally significant for an independent agency: it moves accountability for client relationships, revenue delivery, and team performance to a new principal, while the executive chair position typically signals a mandate for new-business development, acquisitions, or market positioning that the managing director role cannot carry alone. This is one of twelve leadership-change signals we have tracked in the last 90 days across a wide range of sectors and geographies. The related set. Mediasense naming an internal client lead as CEO, Graham executing a planned CEO retirement with a ready internal successor, StashAway losing a founding country manager, reflects a consistent pattern: founder-era leaders reaching tenure thresholds where operational and strategic functions are formally separated rather than held by a single person. The Perth independent agency market is thin enough that this structural move carries outsized signal about Rare's growth intentions. The pattern, particularly among founder-led service businesses reaching scale, creates demand for commercial leadership that can own client retention and organic growth independently of the founder's network, alongside operations leadership capable of holding culture and delivery standards through a principal transition.
