Category of One book by Dominic Su

Not quite the right stage?

If you’d rather experience the ideas live and start defining your own CO1, the Masterclass may fit better.

See where you fit →
  1. Read at your own pace — available in digital and print formats.
  2. Work through the reflection prompts at the end of each chapter.
  3. Use the closing chapter to decide your next step on the CO1 River.

The book will not build your Category of One for you. It is diagnostic and educational — the starting point of the river, not the destination.

Common questions

Is this enough on its own?

For understanding the idea, yes. For applying it to your specific business, most readers move on to the Masterclass or Workbook.

How long does it take to read?

Most readers finish the core chapters in a weekend, then return to the reflection prompts over time.

Do I need to read this before the Masterclass?

It helps, but it isn’t required — the Masterclass covers the same worldview live.
