In Episode 17 of BITE BIG, we go behind the scenes of one of Australia's most successful luxury skincare brands, Rationale, with its trailblazing CEO, Shamini Rajarethnam. From navigating global expansion and regional relocation, to staying ruthlessly focused in a fragmented market, Shamini shares the story of building an enduring brand without compromising on values.
With a mantra passed down from her father, "Nobody cares how much you know until they know how much you care", Shamini's leadership style is deeply human, deeply strategic, and unapologetically clear on what matters most: purpose, people, and integrity.
