This document provides an overview of content marketing for startups. It discusses that content marketing is a resurging marketing model that is important for startups due to factors like the digital age, consumers controlling media, and the value of engagement. It should not be viewed as just publishing content like infographics and videos, but rather require a strategy-first process where startups plan by listening, create an editorial strategy, and define operations before publishing and distributing content and optimizing over time based on what works best. The document recommends startups take an app-like approach, focusing on small-scale testing and learning initially to inform broader efforts.
