HeyReach is a LinkedIn outreach platform built for agencies and sales teams running outbound across many LinkedIn accounts at once. Instead of charging per user, it charges per connected sender, so you can plug in 5, 20, or 200 accounts, rotate sends across them, and manage every reply from one unified inbox. It is cloud-based rather than a Chrome extension, assigns a dedicated residential proxy per sender on the Growth plan, and ships with the most extensive API in the category, including a native MCP server you can drive from Claude or ChatGPT. Anti-duplication stops two senders hitting the same prospect. In a GTM stack HeyReach is the LinkedIn layer. You feed it targeted leads, usually built in Clay, and it scales volume by adding senders rather than pushing one account harder. It connects natively to Instantly, Smartlead, and EmailBison so the same prospect gets an email touch too. At Nebor we run HeyReach as the LinkedIn engine in our multichannel client systems all the time. We build and segment the lists in Clay, route them in, and let it handle the rotation and reply capture across every connected sender, so outreach scales without one account ever carrying all the risk.
