Decagon

Decagon is a San Francisco-based AI customer experience company founded in August 2023 by Jesse Zhang and Ashwin Sreenivas, with additional offices in New York City and London. The company builds, optimizes, and scales AI agents that resolve customer support across voice, chat, email, and SMS channels for enterprise brands including Notion, Eventbrite, Duolingo, Chime, ClassPass, Hertz, Rippling, Noom, Oura, Samsara, Dropbox, Mercado Libre, Bilt, Cash App, Square, Fanatics, and Riot Games. Its platform centers on Agent Operating Procedures (AOPs) — natural-language workflow definitions executed by AI agents — alongside Watchtower for continuous QA, Experiments for live A/B testing, Insights & Reporting analytics, and Suggestions for AI-powered knowledge management. Decagon connects to customer stacks through pre-built integrations (Salesforce, Zendesk, Intercom, Confluence, Contentful, Kustomer, Amazon Connect, RingCentral, Stripe), Model Context Protocol (MCP) servers, and custom API endpoints, but the platform's own developer-facing APIs, SDKs, OpenAPI specs, and technical setup documentation are not published publicly and are made available only to contracted enterprise customers and implementation partners. Decagon has raised $481M across rounds led by Accel, Andreessen Horowitz, Index Ventures, and Coatue Management, reaching a $4.5B valuation following its January 2026 Series D, and was ranked #38 on the 2026 CNBC Disruptor 50 list.
