Today the only real signal is sales. You publish a property, then wait months to see if it sells. An expensive, slow and blunt measure that tells you whether children bought it, never how they actually engaged with it.

Sooper Books publishes original stories, each starring new characters. Children read and listen to them on sooperbooks.com, and we measure exactly which ones they love. That data tells us which characters will win, before a penny goes into production.

Sooper Books creates and finds the characters children love. In weeks. For a fraction of the cost. Using real‑time audience data. HarperCollins produces, licenses and scales the proven winners into global franchises.

Every test runs on sooperbooks.com, where children in nearly every country read and listen to our stories. The site draws 38 million Google impressions a year, and we measure engagement the moment it happens.

Our writers are Emmy‑winning talent who have made children's content for CBeebies, Disney, Netflix and Sky Kids. Our animation comes from a team with credits on some of the biggest names in family entertainment.

This funds three years of testing and data collection, putting a minimum of 50 new IPs through the engine. And a growing pipeline of audience‑validated children's IP, with first claim on every winner.
