Vendors with Visitor Identification

21 vendors in our catalog are built around visitor identification — including AtData, BDEX, Black Crow AI, Bluecore, Celebrus. A further 182 offer it alongside their main job. 200 of the 203 claims cite a page on the vendor's own documentation.

Core means the capability is central to what the product is; supported means it is genuinely offered but is not what the product is for. Most grades come from three separate AI passes over the vendor's documentation, with only a majority verdict recorded; the rest were set by hand. If you already own a tool listed under "also offer", check it before buying a dedicated one.

Most of the vendors here sit on the Customer Engagement Platform, Personalization, Customer Data Platform shelves. That matters when a capability crosses categories — a CDP and a customer engagement platform can both offer visitor identification without being the same kind of tool.

Shortlist from the core list rather than the full one. 21 vendors are built around visitor identification; the 182 below that offer it as a secondary job, which is usually enough if you already pay for one of them and not enough if this is the reason you are buying. We rank by what the evidence supports, never by company size or spend with us.

This page is it, and it is generated from the catalog rather than maintained by hand — a vendor added tomorrow appears here on the next build if the evidence puts it here. 200 of 203 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
