Fathom Video AI

Fathom is a leading conversational intelligence platform that has evolved into a robust API-first architecture by 2026. Architecturally, it leverages a hybrid LLM stack—utilizing proprietary models for low-latency transcription and top-tier models like GPT-4o and Claude 3.5 Sonnet for high-reasoning summarization. The Fathom API enables developers to programmatically access meeting transcripts, AI-generated summaries, and 'Highlights' (atomic units of video intelligence) directly from Zoom, Microsoft Teams, and Google Meet sessions. Its market position is unique as it bridges the gap between simple transcription services and complex enterprise revenue intelligence tools. The API supports advanced webhooks that fire immediately upon meeting conclusion, allowing for real-time data injection into CRMs, proprietary data lakes, or custom agentic workflows. By 2026, Fathom has solidified its place in the enterprise stack by offering SOC2 Type II compliance and granular PII masking at the API layer, making it the go-to solution for developers building automated coaching, legal compliance, or automated project management tools that rely on the 'ground truth' of spoken conversation.
