What Letterbook does

Letterbook is the AI-native alternative to Zendesk, Freshdesk, Zohodesk, and Intercom. We help companies manage and resolve customer support tickets across email, in-app feedback, and website forms. Our AI will triage your tickets, write replies, and build your knowledge base.

No open roles recorded right now.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
