Mintlify Raises $45M Series B at $500M Valuation — Nearly 50% of Documentation Traffic Now Comes from AI Agents

Mintlify·medium signal

Mintlify closed a $45M Series B led by a16z and Salesforce Ventures at a $500M valuation ($67M total raised), powering documentation for 20,000+ companies reaching 100M+ users annually. The key signal: nearly 50% of all documentation traffic now comes from AI agents and AI-assisted workflows, not humans. For builders: documentation is becoming the knowledge layer that AI agents consume to understand and integrate with products. Companies without structured, agent-readable docs are invisible to the AI-native distribution channel.
