The conversation

Milan Savov talks with Theo Kanellopoulos, Head of Marketing at SalesCaptain, about building a marketing and sales engine that produces predictable revenue. Theo says the problem is rarely execution; it is a lack of clarity on the business model, messaging and alignment with sales before scaling activity. Marketing needs leadership buy-in and long-term investment, because companies that expect instant results abandon strategies before they compound.

He explains the difference between lead generation, which captures existing demand, and demand generation, which educates the market earlier, and why companies need both. He also covers treating marketing and sales as one system and how AI is helping both teams share insights.
