Intercom

AI customer service platform that unifies messaging, a Help Desk, and an in-app Messenger. Enables businesses to engage customers across chat, email, and multiple channels while managing conversations, tickets, and knowledge in one place.

Trusted by enterprises including Anthropic and Lightspeed Commerce, with over 25,000 customers. Intercom differentiates through an AI agent that handles complex multi-step queries across chat, email, voice, WhatsApp, and Slack, backed by an App Store of third-party integrations. Server-side SDKs cover Node.js, Ruby, .NET, Java, Go, and PHP.

Key features:

• Messenger and Help Desk with omnichannel messaging and ticketing
• REST API for contacts, conversations, messages, and custom reporting
• Messenger SDKs for web and mobile to embed and customize the chat widget
• Webhooks and developer workspace for building Messenger and Inbox apps
• Integrations with Slack, Jira, Salesforce, and GitHub via Tickets API

Support and product teams use Intercom to scale personalized customer conversations without proportionally adding headcount. Developers integrate via the REST API or SDKs, build custom Inbox apps for teammate workflows, and connect tickets to external systems such as GitHub Issues. The App Store lets teams publish and discover integrations across Intercom workspaces.
