Warm introductions

The warm intro tool built for friends' networks

Cold outreach gets ignored. A warm intro from someone you both trust opens doors. knowswho finds the right person in your friends' LinkedIn networks and routes the intro through your mutual friend — not a cold InMail.

Warm intro vs cold email on LinkedIn

Cold InMails and spray-and-pray outreach get single-digit reply rates. A warm intro works because your mutual friend vouches for you before the first conversation.

knowswho is a warm intro tool built on friends' networks: search who fits, see which friend knows them, and send a pre-written intro your friend approves in one tap.

Why warm intros beat cold messages

Recruiters, investors, and hiring managers respond to people referred by someone they know. The hard part is finding who in your extended network fits — and who can make the bridge.

Search friends' LinkedIn connections in plain English, then request a mutual friend introduction with a forwardable message your connector can send as-is. Not sure what to write? Read how to ask for a LinkedIn introduction — then use knowswho to find who can make the bridge.
