In practice

10 recipes · Martech Cookbook

10 recipes in the Martech Cookbook need identity resolution. Each is a worked use case: the problem, the patterns it composes, and where it fails. Written by Martech Therapy.

  1. Household identity stitching Resolve several people at one address into a household where the buying unit is the household, without letting one member's data quietly drive another's experience
  2. B2B account-level identity resolution Resolve individual visitors to the account they belong to, so the buying committee shows up as one account rather than scattered anonymous leads
  3. Duplicate customer record merge Merge the customer records that drifted apart over time, with the matching rules, the merge decisions, and the rollback path that lets a wrong merge be undone

Identity Resolution / ID Graph — questions

Which vendors offer identity resolution?

90 vendors in our catalog are built around identity resolution — including Acquia CDP, ActionIQ (Uniphore CDP Agent), Acxiom, Adform, Adobe Experience Platform. A further 87 offer it alongside their main job. 156 of the 177 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. 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.

What kinds of platforms have identity resolution?

Most of the vendors here sit on the Identity Resolution, Customer Engagement Platform, Customer Data 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. 90 vendors are built around identity resolution; the 87 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. 156 of 177 claims link the vendor's own documentation, and a blank cell means no verdict either way rather than "no".
