Mintlify builds the documentation platform for software companies. Engineers write docs in Markdown/MDX, and Mintlify publishes them as polished, branded sites with built-in AI search, an in-docs chat assistant, and automated content suggestions tied to the codebase. The core value proposition is shifting documentation from a static artifact to a living, AI-maintained knowledge layer — one that can answer user questions conversationally, update itself when code changes, and now serve as structured context for AI coding agents. Founded in 2022, Mintlify today powers docs for 20,000+ companies — from YC startups to Anthropic, Microsoft, PayPal, Spotify, Coinbase, and X. Its two strategic acquisitions (Trieve for RAG search infrastructure in July 2025 and Helicone for LLM observability/routing in March 2026) signal a deliberate move up-stack: from a docs publishing tool toward infrastructure that makes any company's product knowledge queryable and consumable by AI agents. The buyer is a developer-facing software company that ships a public API or product and needs to manage external documentation at scale.
