What Refer is

Refer is a warm intro tool in the B2B go-to-market stack. In the vendor's own words: “Grow with game-changing intros.” Put plainly, a tool in this category finds the person in your network who can introduce you.

Refer appears in 2 categories here — Warm Intro, Prospecting Database — which usually means it covers more than one job rather than doing a single thing narrowly.

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. Refer sits in the warm intro 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 Refer with M for Mercury

Refer sits on the email side of the stack. Mercury sits on the LinkedIn side and does not try to be your sending platform — Lead Finder returns a verified work email next to every LinkedIn profile and pushes it straight into Smartlead, Instantly, PlusVibe or EmailBison, so Refer keeps doing what it is good at while the connection request and the LinkedIn follow-up run in Mercury. One person, both channels, without the two lists drifting apart.
