AI is fundamentally changing how developers discover, evaluate, and use technology. With tools like Claude Code and Codex increasingly writing and interacting with code, the developer is no longer always the primary evaluator of a developer product the AI agent increasingly is. This changes the rules of Developer Marketing. Documentation is no longer just a resource for developers; it is becoming a critical interface for AI agents. Developer experience must now work for both humans and machines, while marketers face a new challenge: understanding who or what is actually evaluating and using their product. This session explores how AI is reshaping DevX, DevRel, Developer Marketing, and Developer Sales, and why traditional approaches to developer engagement may no longer work. We’ll also explore the emerging role of MCP in building discoverable, agent-friendly developer experiences.
