Local sales agent that finds small businesses, spots buying signals, writes and sends cold email and answers replies, using your Claude or ChatGPT plan.
Harvey (v0.3.0, October 2026, about 3k stars) is a Python app that runs a sales loop on your computer every 15 minutes. It finds local businesses (free from OpenStreetMap, or paid search APIs), collects up to 29 signals you approve such as running ads or no online booking, finds contact emails, writes personalised sequences and classifies replies, with a local dashboard. Every email waits for your approval unless you turn on autopilot. Model calls use Claude Code or Codex on your plan. You need your own mailbox and warmup. Meeting booking is still on the roadmap. MIT.
