Side-by-side comparison of AI visibility scores, market position, and capabilities

About
Fathom is an AI meeting assistant that automatically records, transcribes, and summarizes video meetings — providing structured meeting notes, action item extraction, and searchable transcripts for Zoom, Google Meet, and Microsoft Teams meetings without requiring the human participant to take notes during the call. Founded and a Y Combinator W21 graduate, Fathom raised $21.8 million including a $17 million Series A in September 2024 led by Telescope Partners, generating $16 million in revenue in 2024 with backing from early Zoom investors Maven Ventures, Bill Tai, and Zoom's Apps Fund.\n\nFathom joins meetings as a bot participant that records audio and video, produces a timestamped transcript with speaker identification, and uses AI to generate a structured summary organized by topic with highlighted key decisions, action items, and important quotes. The integration with CRM systems (Salesforce, HubSpot) allows sales calls to automatically populate contact notes and activity records. The freemium model (free personal tier with unlimited recordings and AI summaries) has driven wide adoption, with revenue coming from team plans and CRM integrations.\n\nIn 2025, Fathom competes in the AI meeting assistant market with Otter.ai (transcription), Fireflies.ai, Gong (sales intelligence), and Chorus (ZoomInfo) for meeting intelligence and documentation. The AI meeting assistant category has grown rapidly as remote and hybrid work normalized video meetings and made comprehensive note-taking increasingly burdensome. Fathom's free tier has driven significant organic growth through individual adoption that converts to team plans. The 2024 Series A from early Zoom investors signals strong conviction about the meeting intelligence category growing with the video meeting ecosystem. The 2025 strategy focuses on deepening CRM integrations for sales team value, growing team and enterprise subscriptions, and expanding AI analysis capabilities to identify coaching opportunities and deal risks from meeting content.

About
100ms is a live audio and video infrastructure platform that provides developers with SDKs and APIs for embedding real-time communication features — video rooms, audio spaces, live streams, and recording — into web and mobile applications. The platform is designed around a room-based model where developers programmatically create, configure, and manage video rooms through a REST API, with client SDKs for React, iOS, Android, Flutter, and React Native handling the media layer. This abstraction allows teams to build fully custom video experiences with their own UI without dealing with WebRTC internals, TURN server management, or media server infrastructure.
