The author's own brand — a free-plus-shipping book that markets King Kong, the agency he actually sells.
The person and the brand are the same here, as with James Clear: Sell Like Crazy isn’t sold to make money on the book itself (it’s free plus shipping), it’s sold to put King Kong’s “selling system” in front of business owners who might later book a strategy call. The book and the agency share every proof point — $7.8B in client sales, 1,067 niches, the same named case studies — because they’re the same pitch at two different price points: free, and a $1,000-value call.
