Mintlify raised a $45M Series B led by a16z and Salesforce Ventures at $500M valuation, now powering documentation for 20,000+ companies reaching 100M+ people annually. The critical data point: nearly 50% of traffic to documentation now comes from AI agents and AI-assisted workflows. Documentation has become the product's interface to AI — a system of record that agents rely on to take action, not just a reference for human developers.
