AI in content discovery

Zihan Wang and her co-founder Lucy Clarke are both avid readers. But they found it frustrating to see the same bestseller recommendations over and over again. Wang and Clarke were itching to see titles that they were actually interested in – not just what was popular. The duo also have day jobs in the tech space, and saw that AI offered a unique opportunity to change how people discover content that resonates with them. So earlier this year, the Berlin, Germany-based co-founders launched Zilu, an app allowing users to discover a whole host of books they might not have known about before. Editor’s Note: Zilu has been named to The Story Exchange’s 2025 list of 10 Brilliant Business Ideas. Here's our lightly edited Q&A with Wang. How is your business different from others in your industry? Zilu focuses on discoverability. We help readers find what resonates instead of what's popular.
