About
Otter.ai is an AI meeting intelligence platform founded in 2016 by Sam Liang and Yun Fu in Mountain View, California. The company was built on the insight that conversations and meetings are the most information-dense and least captured medium in the modern workplace — and that real-time AI transcription could transform how teams capture, search, and act on spoken knowledge. Otter's initial product was a live transcription application that produced searchable, speaker-attributed transcripts of meetings, calls, and voice notes with significantly higher accuracy than existing dictation tools.\n\nOtter's platform has evolved into a full meeting intelligence system that includes real-time transcription, AI-generated meeting summaries, action item extraction, a meeting chatbot for querying transcript content, and integrations with Zoom, Google Meet, and Microsoft Teams. Enterprise features include custom vocabulary, team workspaces, compliance-grade data retention, and an API for embedding Otter's transcription capabilities into third-party applications. In October 2025, Otter launched an enterprise API and an MCP (Model Context Protocol) server, enabling AI agents to query and act on meeting intelligence programmatically.\n\nOtter.ai hit $100M ARR in March 2025, a milestone achieved with 25M+ users and a notably lean cost structure of approximately $500K in revenue per employee. The company has remained privately held and has not disclosed a primary capital raise, operating profitably at scale. Otter competes with Fireflies.ai, Fathom, and Zoom AI Companion in the meeting intelligence market, with its long operating history, transcript search quality, and enterprise integrations as primary differentiators.
