AutoScout24, one of the world's largest automotive marketplaces, is saving approximately one million working hours annually through a single AI-powered workflow built on OpenAI's Codex. Global Chief Product Officer Justin Re is driving the adoption across the entire organization, not just engineering.

The company built a functional AI agent in 48 hours. That number matters. It signals a shift in build cycles, not just productivity metrics. AutoScout24 is explicitly targeting what Re calls 'hands off coding,' a state where developers direct rather than write.
