The Unpublished David Ogilvy, edited by his longtime colleague Joel Raphaelson, is a collection of memos, letters, speeches, and private notes Ogilvy wrote over five decades at Ogilvy & Mather. Assembled as a surprise gift for his 75th birthday, it captures him thinking out loud to his own people rather than performing for a public audience, on subjects ranging from hiring and management to creativity and client relationships. Because the material was never intended for publication, it reads as more candid and unguarded than his bestselling books.
This is Ogilvy without the polish — the internal memos he actually sent to his agency, which makes it arguably more useful to a founder than his public-facing books. He is blunt about hiring only people better than himself (his famous "Russian nesting doll" memo, where he gave each new office head a doll with a note inside: "If you always hire people who are smaller than you are, we shall become a company of dwarfs. But if you always hire people who are bigger than you are, we shall become a company of giants"), and equally blunt about firing clients and employees who don't meet his standards.
For founders building a culture rather than just a product, the value here is in seeing how a founder actually communicates standards internally: short, sharp, repeated memos rather than one-time speeches. Ogilvy treated internal writing as seriously as external advertising, understanding that the culture of a company is built from the accumulation of small, clear directives, not a single mission statement.
