Identity Resolution / ID Graph — questions

Which vendors offer identity resolution?

79 vendors in our catalog are built around identity resolution — including ActionIQ, Acxiom, AdForm, Adobe Experience Platform, Adobe Real-Time CDP. A further 63 offer it alongside their main job. 122 of the 142 claims cite a page on the vendor's own documentation. It is also called "id graph"; the same record covers both.

What is the difference between core and supported identity resolution tools?

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.

What kinds of platforms have identity resolution?

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

Which identity resolution providers and companies should I shortlist?

Shortlist from the core list rather than the full one. 79 vendors are built around identity resolution; the 63 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.

Is there a list of identity resolution software?

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. 122 of 142 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
