Decagon

Decagon builds AI agents for enterprise customer service across voice, chat, email and SMS. Its agents connect to company workflows and knowledge bases to answer product questions, process refunds and cancellations, and act within existing business systems. Customers include Avis Budget Group, Chime and Oura Health. Alongside customer-facing agents, Duet helps teams analyze conversations, suggest workflow changes and test agent behavior, giving support teams tools to improve their deployments.

Founded in 2023 by Jesse Zhang and Ashwin Sreenivas, Decagon is led by Zhang as CEO and Sreenivas as president. Its Agent Operating Procedures define agent behavior through natural-language workflows. These procedures also underpin Duet, connecting its reasoning to platform tools for testing, versioning and conversation analysis. Keeping the logic in inspectable procedures lets non-engineering teams understand how Duet operates and contribute to its development.

In January 2026, the company reported adding more than 100 new global enterprise customers during the preceding fiscal year. It also raised a $250 million Series D led by Coatue Management and Index Ventures at a $4.5 billion valuation. Sacra estimates that Decagon’s annualized revenue reached $100 million in July 2026.
