What successful company has Taber solo founded? The about section on that marketing page doesn't really inspire me to fork over $199.
He's also done a few other side projects and seems pretty involved in the startup community.
The book also includes feedback from pretty respected people in the small startup space:
Patrick McKenzie - Kalzumeus Software
Brennan Dunn - DoubleYourFreelancing.com
Gabriel Weinberg - Founder of Duck Duck Go
Josh Ledgard - CoFounder of KickoffLabs
Brian Casel - Founder of Restaurant Engine
Dr. Sherry Walling - Clinical Psychologist
Hiten Shah - Crazy Egg & KISSmetrics
Justin Jackson - Product People
Nathan Barry - ConvertKit
Also the book is only $39. Mike should pay me for this promotion, haha.
