We believe in the power of ideas

Our team of experts and PhDs have helped us curate and explain the 160 books that have shaped the world, and their wisdom can empower anyone to think smarter. Learn how to find creative solutions where other people see only a mass of information - and become a more powerful persuader - using ideas from the books you feel you should know (but will never have time to read).

And there’s so much more to come: we’re now working with the University of Cambridge to develop tools that will empower anyone to think more creatively and critically.
