What Readers Are Saying

★★★★★ 5.0 average rating

"The missing playbook for founders transitioning from operator to investor."

Having scaled an agency from $20M to over $200M in ARR, I've seen firsthand how a lack of clear business architecture creates a ceiling for growth.

"A smart, practical lens on what to do with profits."

The models are easy to follow, grounded in real businesses, and make capital allocation feel tangible.

"It answers the 'what's next?' question most profitable founders wrestle with."
