Building Marlo: an open-source AI CMO for founders and startups
6 November 2026 · Also published on DEV
Founders spend their days building, fixing bugs and talking to customers. Marketing piles on top: competitor research, keywords, blog posts, LinkedIn and X content, Reddit, SEO, lead generation, and keeping all of it consistent. Most founders either lose too much time to it or can't afford a marketing team. That is why we built Marlo.
