About | Marianna Costa

Marianna Costa

Principal

The Reputation Agency

Marianna Costa is a senior marketing leader who builds brands that hold their value under commercial pressure and turn positioning into revenue. 

With 25 years of experience across peak bodies, industry networks, tourism, manufacturing, and government-funded organisations, Marianna has built or rebuilt brands at five organisations. Her work ranges from brand personality frameworks at Tourism Victoria to a full visual identity at Langdon Ingredients and a brand playbook at Industry Capability Network Victoria. 

She starts with brand clarity: what the organisation stands for, who it is for and what it will not claim. From there, she sets the strategy and builds the machinery to run it. This includes the marketing technology stack, connecting CRM, automation, content, and analytics, so campaign performance can be traced back to the strategy that produced it. 

Her commercial record across services and products includes Gateway Activate, a bundled B2B subscription product she conceived at ICN Victoria and adopted nationally, and the Henry Langdon retail range, which grew into a global brand within three years. 

Marianna holds a Master of Marketing and a Graduate Certificate in Digital Marketing Leadership from RMIT. 

Helping clients succeed, she takes pride in building relationships that deliver results.
