Sitefire

Sitefire is a Generative Engine Optimization (GEO) platform — the marketing suite for the agentic web and a self-described System of Record for AI visibility. It monitors how AI models (ChatGPT, Gemini, Perplexity, DeepSeek, Google AI Mode and AI Overviews) mention and cite a brand across tracked topics, diagnoses why content is or isn't cited using its 4C content classification, and generates actionable briefings plus AI-optimized articles that publish directly to CMS platforms such as Webflow and Framer. Sitefire connects to analytics (GA4, Cloudflare, AWS CloudFront) to measure AI referral and crawler traffic, and exposes its data and content workflows to AI agents through an official hosted MCP server (Spark) and a published Agent Skills bundle. A small public, unauthenticated REST API books product demos. Sitefire is a Y Combinator (W2026) company.
