Sellbird (formerly Harvey): the open-source outreach platform that runs on your Claude or ChatGPT plan. Finds companies and decision makers, verifies emails, writes personal cold email, sends it and handles the replies.

A sales agent that runs loops on your Claude or Codex plan — Harvey is an autonomous agent that discovers prospects, profiles them, drafts personalized cold emails, sends campaigns, and works replies toward meetings. It runs continuously on your machine using your existing Claude Pro/Max or ChatGPT subscription instead of a metered model API, and ships with a local dashboard for approving outreach and pricing discovery runs before they spend anything.
