Vendors with Cross-device Matching

12 vendors in our catalog are built around cross-device matching — including Aqfer, Branch, Celebrus, Experian Marketing Services, Eyeota. A further 35 offer it alongside their main job. 40 of the 47 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. The grade comes from three independent reviews of the vendor's documentation, and only a majority verdict is recorded. 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 Identity Resolution, Data Onboarding, Customer Data Platform shelves. That matters when a capability crosses categories — a CDP and a customer engagement platform can both offer cross-device matching without being the same kind of tool.

Shortlist from the core list rather than the full one. 12 vendors are built around cross-device matching; the 35 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. 40 of 47 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
