Data Management Platforms (DMP)
The classic third-party cookie DMP has largely gone, and what remains splits into three groups: publisher-side platforms that build audiences from their own first-party data, identity and onboarding providers that connect a company's CRM records to advertising platforms, and audience data marketplaces that sell ready-made segments. Buyers are usually programmatic media, audience or data teams deciding how first-party data reaches a DSP without breaching privacy rules.
What is data management platforms (dmp) software?
Data management platforms collect, segment and distribute audience data for advertising.
How many data management platforms (dmp) platforms are there?
The Opsmarshal Terminal tracks 21 active data management platforms (dmp) platforms as of 2026-08-30, within a marketing technology landscape of 15,505 products. Each entry links to the vendor’s own site and, where one was captured, its review source.
What to look for
- Be clear which of the three jobs you are buying: publisher audience building (Permutive, Audigent), identity and onboarding (LiveRamp, TransUnion, Experian, Semcasting), or third-party segments (Eyeota, Datonics, Alliant). Vendors market across all three; the products are not interchangeable.
- Match rate against your own file is the only number that matters for identity vendors. Every one of them will run a test file, so run it before signing rather than trusting a published coverage figure.
- Third-party segment quality varies by individual segment, not by vendor. Test at segment level in a live campaign against a control before committing budget.
- Data provenance is now a legal question, not just a quality one. Ask where consumer data came from, what consent it carries, and how the vendor handles US state privacy law and GDPR deletion requests.
- Geography decides more than feature lists. US-centric providers thin out fast in Europe and Asia-Pacific, which is the entire reason Eyeota and Adsquare have buyers.
- Clean rooms (InfoSum, Optable, LiveRamp) are absorbing what DMPs used to do. If your real need is a data partnership with one retailer or publisher, that is a clean-room purchase, not a DMP purchase.

How this list is built. Platforms are placed in this category by their
public positioning, and ordered alphabetically by company name — this is a reading order,
not a ranking, and it does not indicate quality, popularity, or evidence strength. Ratings appear only where captured
from a named review source with a capture date; a missing number means no qualifying evidence stored,
not a judgment about the vendor. Vendor and review links are unpaid and carry nofollow.
Sponsored placement, where it exists, is labeled separately and never reorders this list.
