Intercom

Intercom is a customer communications platform providing live chat, targeted email campaigns, help center (knowledge base), product tours, and AI-powered customer support automation. Founded in 2011, Intercom is used by over 25,000 businesses including Atlassian, Amazon, and Shopify, and is particularly popular with SaaS companies that need to support, onboard, and engage users across the entire customer lifecycle from within their product. Intercom's AI agent, Fin (powered by GPT-4), resolves a significant percentage of customer queries automatically by answering from the help center knowledge base and conversation history — without requiring human escalation. Fin's resolution rate (the percentage of queries it fully handles without human intervention) averages 40–75% depending on documentation completeness. Intercom's product is organized around three "Surfaces": the messenger (in-product chat widget), the inbox (team conversation management), and outbound messages (email, in-app, push, SMS campaigns for user engagement and onboarding sequences).
