Verve CEO Remco Westermann Predicts Huge Growth for LLM Advertising

In an interview, Verve CEO Remco Westermann discusses the impact of AI on consumer trust and advertising. He cites a Verve study showing that users distrust AI-generated content, especially younger demographics (45% of 18-24-year-olds), but trust AI as a personal advisor and shopping assistant. Westermann sees this trust as a huge opportunity for LLM-based advertising, predicting that chatbots will eventually become ad-funded, similar to Google's evolution. He advises brands on AI disclosure, emphasizing its importance for trust, but suggests it should not overshadow the message. For comparison platforms like Check24 or Booking.com, he advises integrating AI capabilities to offer personalized advice. He believes LLM advertising will be 'very big', with a mix of premium and programmatic ad sales, and notes that consumer offerings will rely more on advertising than B2B models.

• Verve CEO Remco Westermann predicts LLM advertising will become 'very big'.
• A Verve study shows 45% of 18-24-year-olds report a loss of trust in AI-generated content.
• Verve's main business is in the USA, where AI usage in advertising faces less critical questioning than in Germany.
