What tool identifies anonymous website visitors by company?

A common tool for identifying anonymous website visitors by **company** is **Leadfeeder**. It uses reverse IP lookup to match a visitor’s IP address to a company, rather than to an individual person.[1]

Other tools that do the same at the company level include **Factors.ai**, **Snitcher**, **Warmly**, **Leadinfo**, and **ZoomInfo WebSights**.[2][4][5][7]
