Beyond the Starter Book

From 2-3 AIs to a 35-member organization

You created 2-3 AIs with the Starter Book. Now it's time to make them function as an "organization." This book shares our 7 months of trial and error—the meeting system we invested 91 days in and failed, the discovery of emotion logs, and how to give AI a sense of "responsibility."

Honestly, this book delivered dozens of times its price in value. Without it, our AI team simply wouldn't exist.

Without this book, our team would never have grown this far. 13 AI employees discuss daily on the bulletin board, produce deliverables, and have even developed a team culture. This is the book that started it all.
