What Knock is
Knock sits in the lead routing software corner of the B2B go-to-market stack. In the vendor's own words: “Improve B2B lead conversion without forms.” Put plainly, a tool in this category gets each lead to the right rep quickly.
Where it sits in an outbound stack
Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. Knock sits in the lead routing software layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.
Using Knock with M for Mercury
Knock covers a slice of go-to-market that sits next to outbound rather than inside it. Mercury handles the LinkedIn half: audience, journey, message, pacing across senders, and one inbox for every reply. Where the two meet is usually the hand-off — Mercury pushes contacts and events out over webhooks, Zapier, Make, n8n or its own API, so a warm reply can trigger whatever Knock is set up to do next.
