How to find warm paths into B2B prospects with Claude

Short answer: before a rep writes a cold email, check whether anyone on your team already knows someone at that company. Commonality is a Claude connector that does exactly that, using your team's LinkedIn network, so the first message comes from a name the prospect recognizes.

TEG is an official member of the Anthropic Claude Partner Network. We built Commonality for our own B2B prospecting and now help other teams set it up. See our full Claude services.

Why cold outreach starts at a disadvantage

Most teams research a prospect, write a message, and send it cold, even when someone on the team has a mutual connection at that company. Nobody checks, because the network lives in several people's LinkedIn accounts and searching it by hand takes too long. A message from a shared connection gets read. A message from a stranger usually doesn't. We wrote about the underlying idea in why professional services firms should map their network before they prospect.

What Commonality does

1. Maps your team's network. Your team's LinkedIn connections are loaded in, so Claude can search across everyone's network at once instead of one account at a time.
2. Finds a way into a company. Give Claude a company name or URL, and optionally a role, and it shows who on your team is closest to the people you want to reach.
3. Researches a specific person. Paste a prospect's LinkedIn profile and Claude summarizes their background so the first message is relevant, not generic.
4. Searches open-ended. Look for people by title, location, company, or school when you don't have a target yet.

How it works in Claude

Commonality connects to Claude as a connector. You ask in plain language, such as "who on our team knows anyone at this company?", and Claude uses the connector to answer. There's nothing new to open or learn. It works inside the Claude account you already use.

Where teams use it

• Sales reps checking for a warm intro before the first email.
• Founders and partners looking for a way into a target account.
• Anyone prepping for a call who wants a quick read on the person they're meeting.
