James MacDonald, Founder of Limelight, joins That’s What I Call Marketing to discuss programmatic advertising, building a global ad tech business, AI and why simplicity still matters for marketers today.
This episode explores the journey from Fleet Street advertising sales to modern programmatic technology, through a practical conversation about risk, reinvention, customer focus, remote culture and building technology that solves real problems.
In this episode, we cover:
– What Fleet Street taught James about sales, resilience and asking for the business
– Why helping people buy is more powerful than pushing people to buy
– How James identified the gap that led to Limelight
– Why programmatic advertising still needs simplicity, support and better execution
– How Limelight thinks about AI, interoperability and the importance of human judgement
– What it takes to build and maintain a strong remote culture across a global team
