Seth Godin

American marketing executive and prolific author who wrote Tribes, Purple Cow, Permission Marketing, The Dip, and Linchpin — and who has published a blog post every day for 20+ years — known for contrarian, aphoristic takes on marketing, leadership, and creativity.

Invented permission marketing and the purple cow framework — Permission Marketing (1999) argued that interruption marketing was dying and the future belonged to consensual marketing relationships; Purple Cow argued that remarkable products market themselves and that mediocrity is the riskiest strategy.
