⏳ [16:30] The Pandemic Pivot: Turning Crisis into Growth

• COVID-19 shut down outdoor advertising, leaving Flow City in crisis.

• The tech team used the downtime to develop better automation.

• Breakthrough moment: Secured direct access to premium ad networks, unlocking major growth.

⏳ [21:00] AI’s Role in Pricing & Campaign Optimization

• AI helps brands find the best locations at the best prices.

• Avoiding high-cost ad slots by identifying when advertising competition is lower.

• Strategic ad buying: Instead of running for two weeks, brands can spread ads over months for better impact.

 

⏳ [25:15] Challenger Brands vs. Big Advertisers

• Big brands are slow to adopt change, while small brands use AI to disrupt the market.

⏳ [34:00] The Future of Digital Out-of-Home Advertising

• 3D digital ads & transparent screens are the next big innovations.

⏳ [37:30] Startup Challenges & The London VC Scene
