Your best-fit buyers share a pattern, and the 'People also viewed' box on LinkedIn barely scratches it. CUFinder's Contact Lookalike Finder does the real work. Feed it a person by work email or LinkedIn URL, and AI builds a 360-degree profile from that person's posts, reactions, and activity - and their company's - then returns the top 25 contacts who match. Unlike tools that only accept a LinkedIn URL, CUFinder also works from a work email. So you can clone a champion, an ICP persona, or a closed-won contact into a fresh list in seconds.

Why Choose Our Contact Lookalike Finder
Most lookalike tools just read the 'People also viewed' column on a LinkedIn profile. CUFinder goes deeper. Its AI and machine-learning models read each person's posts, reactions, and activity - plus their company's - to build a true 360-degree profile, then rank the 25 closest matches by real behavioral and firmographic similarity. And because it accepts a work email as well as a LinkedIn URL, you're not limited to contacts you already have a profile link for.
