Great introduction to the PLG model as a new paradigm to win, grow, and keep customers.

Easy to read, highly actionable content, even when the Americans love their 3-letter frameworks a lot. Also helps to actually implement PLG, e.g., by guiding through quizzes to find out whether freemium or free trials, etc., are appropriate for a specific type of business. See also the later addition, The product-led playbook.
