Decagon

Decagon is a US conversational AI company whose platform lets enterprises build, optimise and scale AI agents that act as a concierge for every customer across voice, chat, email, SMS and messaging channels. Its stated aim is to make every customer feel like the only customer, turning customer experience operations into a growth driver without adding headcount. Decagon is backed by investors including a16z, Accel, Bain Capital Ventures, Coatue and Index Ventures, and its customers include Avis Budget Group, Chime, Oura Health, 1-800-FLOWERS.COM and Hunter Douglas; American Airlines and Deutsche Telekom appear among the logos on its site.

Platform

• Agent Operating Procedures (AOPs) that let non-technical teams define agent workflows in natural language, with Duet and Duet Apprentice tools for building and iterating agents without engineering sprints
• Decagon Voice, built on the company's own Chord speech model, supporting more than 70 languages with automatic detection, interruption handling, hundreds of brand-tuned voices, outbound calling and summarised handoffs to human agents
• Chat for web, mobile, SMS and WhatsApp with branded interfaces, dynamic greetings, structured inputs, rich media carousels and multi-brand management, plus always-on email agents
• A proprietary engine that keeps customer context across sessions and channels, a network of frontier and specialised models, built-in guardrails and data controls, and testing, observability and analytics suites
• Decagon Assist for human agents, with live transcription, auto-generated summaries and replies, and a Personal Agent Gateway that detects customers' own AI agents and serves them through a dedicated channel with controlled permissions
