In this episode, Marc and Vassilis explore the invisible mental models that shape marketing decisions, questioning long-held beliefs such as the funnel model, the five times customer acquisition myth, and the effectiveness of purpose-driven marketing.

They discuss the cashflow funnel as a more accurate representation of customer journeys and emphasize the importance of mental availability in driving growth. The conversation highlights the disconnect between customer satisfaction and revenue, urging marketers to adopt better models for understanding and measuring success.

Enjoy the show!
