About
Mintlify is a developer documentation platform that uses AI to auto-generate, update, and maintain software documentation from codebases — providing beautiful, searchable documentation sites with AI-powered search and chat, code snippet integration, and automatic synchronization with code changes that ensures documentation stays current. Founded and headquartered in San Francisco, Mintlify raised $21.7 million total including an $18.5 million Series A led by Andreessen Horowitz with HubSpot Ventures and Bain Capital Ventures, serving 3,000+ customers and reaching $1 million+ ARR.\n\nMintlify's platform enables development teams to create and maintain API documentation, SDK guides, and product documentation that looks polished and stays current with the actual codebase. The AI layer can generate documentation from code comments and function signatures, suggest documentation improvements, and help users find answers through an AI chat interface built into the docs. Notable customers include Anthropic, Cursor, Perplexity, and Zapier — fast-growing AI and developer tools companies whose developer-facing documentation is a core part of their product experience.\n\nIn 2025, Mintlify competes with GitBook, Readme.com, Docusaurus (Meta open-source), and Notion for developer documentation platforms. Developer documentation has become a critical competitive differentiator for API companies and developer tools — poor documentation creates friction in developer adoption, and the best documentation experiences (like Stripe's) become competitive advantages. Mintlify's 1.5 million+ developers using documentation hosted on the platform monthly creates network awareness. The Andreessen Horowitz backing signals strong conviction about the market opportunity. The 2025 strategy focuses on deepening AI documentation generation capabilities, growing enterprise features for large engineering organizations, and expanding beyond developer tools to technical documentation for any software company.
