I think,
therefore
I know.

“Brad’s book dives into how unexamined assumptions and ‘common sense’ thinking can hinder meaningful learning inside organizations… It’s a useful reminder that improvement is rooted in curiosity, humility, and a willingness to test our assumptions.”

Mike Rother, author of Toyota Kata

“The book that I highlighted the most ever.”

Egor Savochkin

“I read a lot of books, but this one felt special to me. Brad was able to capture thoughts and feelings that I’ve had for years and express them in ways I have always struggled with. If you want to understand why organizations struggle to change, why frameworks never feel quite right, and learn to diagnose the problems, I would highly recommend this book.”

Jim Hendriks

“If you want to understand why you’re not getting the results you want, you should read this book.”

Mike Bowler

“I Think, Therefore I know made a huge impression on me. It is insightful, easy-to-read and full of great advice. Definitely in the top 10 books I ever read.”

Bertold Kolics

“For CEOs, founders, and executives, this book is invaluable… Despite its intellectual depth, it remains accessible, engaging, and clearly structured. No buzzwords. No self-promotion. Instead, it offers concrete insights and numerous moments that make you think: ‘That is reality.’”

Roman Didier

“What stood out most is your focus on real problem-solving, backed by concrete examples and evidence, not theory. It’s usable. I’ll be buying copies for our management team.”

John Neels

“Great book! One of the best I have read on organizations. Every sentence for me was, ‘Yes! This is exactly what I have seen too!’”
