The 12 tools, reviewed
#1 Zeotap
Composable CDP that runs inside your own Snowflake instance · Germany · zeotap.com
Snowflake Native App Identity resolution and activation EU-headquartered (Germany)
Zeotap is the most CDP-first product on this list: identity resolution, enrichment and activation are the whole company, not a module inside something larger.
- Pricing: Quote only. Not published; every deployment is quoted after a sales conversation. No free trial is advertised. Free plan: none stated.
- Best for: Teams that already run Snowflake and want the CDP inside their own warehouse
- Strengths: Cross-channel identity resolution; Audience enrichment; Segment activation to marketing and advertising destinations.
Where it falls short
Zeotap publishes no pricing anywhere on its site and no free trial is advertised, so a buyer cannot size a deployment without a sales call.
Wrong for
A small team wanting to self-serve a plan and see a price before talking to sales, since Zeotap publishes nothing and offers no free trial.

#2 mediarithmics
Cookieless-first CDP with built-in audience monetization · France · mediarithmics.io
Cookieless-first design Audience monetization EU-headquartered (France)
mediarithmics was built cookieless-first rather than retrofitted, which is a genuine differentiator as third-party cookies continue to disappear, and it combines customer data unification with the ability to monetize audience data directly rather than only using it internally. Its recent merger with Easyence extends the product into on-site personalization and search.
- Pricing: Quote only. Not published; every deployment is quoted after a sales conversation. No free trial is advertised. Free plan: none stated.
- Best for: Publishers and consumer brands planning their personalization and monetization strategy around the end of third-party cookies
- Strengths: Real-time customer data unification; Cookieless identity resolution; Audience monetization.
Where it falls short
No pricing is published anywhere and no free trial is advertised.
Wrong for
A buyer who wants to compare published pricing across vendors before a sales call, since mediarithmics discloses none.

#3 Spotler Activate
Dutch ecommerce CDP, formerly Squeezely, now part of Spotler Group · Netherlands · spotler.com
Ecommerce-focused CDP Formerly Squeezely EU-headquartered (Netherlands)
Spotler Activate is purpose-built for ecommerce, unifying customer and behavioural data into real-time segments and triggers rather than acting as a generalist profile store retrofitted for retail. Being part of Spotler Group gives a buyer the option of one Dutch vendor across CDP, email and marketing automation rather than three separate contracts.
- Pricing: Quote only. Not published; the vendor routes every buyer to a demo or quote request. No free tier is advertised. Free plan: none stated.
- Best for: Ecommerce teams wanting one Dutch vendor for the CDP and, if needed, the rest of the Spotler Group's email and automation stack
- Strengths: Customer and behavioural data unification; Real-time segmentation and triggers; Ecommerce personalization.
Where it falls short
The product was recently renamed from Squeezely to Spotler Activate as part of its move into Spotler Group, so older research and case studies under the Squeezely name may not reflect the current product or support team.
Wrong for
A buyer who wants a CDP with a long, stable brand history to research, since the recent Squeezely-to-Spotler-Activate rename makes older third-party material about the product harder to trust at face value.

#4 RudderStack
Warehouse-native CDP with a perpetual free tier and self-hosted option · United States · rudderstack.com
Perpetual free tier Self-hostable (Elastic License 2.0) Warehouse-native architecture
RudderStack takes the position that a customer's own warehouse is already the system of record, so it collects events, stitches identities and delivers to destinations without becoming a second store, and its Community Edition can be fully self-hosted under the Elastic License 2.0, with the same core processing layer as the cloud product.
- Pricing: Free + paid tiers. Free plan: 250,000 events/month perpetual, 16 SDK sources, 200+ destinations. Free plan: free plan.
- Best for: Technical teams that want to keep the customer profile store in their own warehouse rather than a vendor-hosted one
- Strengths: Event collection and identity stitching; Warehouse-native profile storage; 200+ destination integrations.
Where it falls short
Marketer-facing segmentation and audience-building tools are thinner than the packaged platforms on this list, and usage-based pricing scales with event traffic rather than with an approved budget.
Wrong for
A marketing team that wants to build and manage audiences directly through a polished interface without engineering support, since RudderStack is built around a technical, warehouse-native workflow.

#5 Bloomreach
Commerce-experience CDP with AI-driven ecommerce personalization · United States · bloomreach.com
Bloomreach Engagement (formerly Exponea) AI-driven segmentation Amsterdam-founded, now US-headquartered
Bloomreach Engagement (formerly Exponea, acquired 2021), now sold as Autonomous Marketing, is a genuine, well-funded CDP with strong ecommerce personalization and AI-driven segmentation.
- Pricing: Quote only. Not published; an annual subscription made of a module fee plus a usage-based fee, quoted after a sales conversation. No free trial found. Free plan: none stated.
- Best for: Ecommerce and retail brands wanting a single-customer view across web, CRM, warehouse and offline data with AI-driven segmentation
- Strengths: Single customer view across website, CRM, warehouse and offline data; AI-driven audience segmentation; Multichannel activation (Loomi AI-orchestrated).
Where it falls short
No pricing is published anywhere and no free trial was found, so budgeting requires a sales conversation.
Wrong for
A buyer who needs to see a published price or run a free trial before a sales conversation, since Bloomreach discloses neither and quotes every deal.
Visit Bloomreach →
#6 Piwik PRO
Polish analytics suite with a published-pricing CDP module · Poland · piwik.pro
Published entry pricing 30-day free trial EU-headquartered (Poland)
Piwik PRO is one of the few vendors on this list with a published starting price that covers its CDP feature (Business from €36/month, including a capped 300 Data Activation profiles/month) and a 30-day free trial, which makes it one of the easiest products here to evaluate without a sales call.
- Pricing: Free trial + paid tiers. Business plan from €36/month (up to 2M actions/month, 20 domains, 300 Data Activation profiles/month, 25-month retention). Free plan: free trial.
- Best for: Organisations that want analytics, consent management and a CDP module from one EU vendor with published pricing
- Strengths: Web analytics; Tag manager; Consent Management Platform (CMP).
Where it falls short
The Data Activation (CDP) allowance is capped even on the entry paid tier (300 profiles a month on Business, 1,000 on the cheapest Enterprise tier), and a buyer who wants a CDP specialist rather than an analytics-suite module will find Piwik PRO's identity resolution lighter than the dedicated CDP vendors on this list, even though it lists 1,000+ destinations via direct integrations, webhooks and automation tools.
Wrong for
A consumer brand or publisher that needs deep, high-volume identity matching as its primary requirement, since Piwik PRO's CDP module is profile-capped on most tiers and secondary to its analytics suite.

#7 Commanders Act
French CDP bundled with server-side tag management and consent · France · commandersact.com
Server-side tag management + consent + CDP Adloop ad-optimisation (acquired 2023) EU-headquartered (France)
Commanders Act, the trading name of Fjord Technologies (SIREN 527 730 782), built its CDP outward from a server-side tag management business, so consent state, collection and the unified customer profile all sit with one French vendor rather than three separate tools. Its 2023 acquisition of Adloop adds ad-spend optimisation to what is now a three-part suite.
- Pricing: Quote only. Not published; every plan is quoted after a sales conversation. No free trial is advertised. Free plan: none stated.
- Best for: European marketing and data teams that want consent, server-side tag collection and the CDP profile from one French vendor
- Strengths: Real-Time CDP: customer unification and segmentation; Enterprise Tag Manager (server-side collection); Consent management.
Where it falls short
No pricing is published anywhere and no free trial is advertised.
Wrong for
A buyer who wants a CDP specialist rather than a combined tag-management, consent and CDP suite, since Commanders Act's customer data platform is one part of a broader product.
Visit Commanders Act →
#8 mParticle
Mobile-first CDP with strong data governance, now part of Rokt · United States · mparticle.com
Mobile-first identity resolution Per-destination data governance Now "mParticle by Rokt"
mParticle is the strongest option on this list when the primary product is a mobile app: its SDKs are well maintained, cross-device and reinstall identity is handled properly, and per-destination filtering lets a team send a partner only the attributes it is entitled to rather than a full profile. That governance depth suits regulated sectors well.
- Pricing: Quote only. Not published; every plan is quoted with volume commitments after a sales conversation. No free tier is advertised. Free plan: none stated.
- Best for: App-first companies that need device identity resolution and strict, per-destination data governance
- Strengths: Cross-device identity resolution; Per-destination data filtering and governance; Mobile SDK coverage.
Where it falls short
mParticle has completed a merger with Rokt and now operates as "mParticle by Rokt," which makes the product's independent roadmap and support structure a real open question for a buyer relying on it long-term.
Wrong for
A small team with simple, web-only tracking needs, since mParticle's strengths and enterprise commercial structure are built for mobile-first, high-governance use cases.

#9 Tealium
Established tag management and CDP platform run by marketers · United States · tealium.com
Long-established incumbent (founded 2008) Tag manager + CDP combined Marketer-run, no engineering required
Tealium sells independence from the data team: tags, consent, profile unification and audience delivery in one product, administered by marketers rather than engineers. Its AudienceStream product, launched in 2013 and self-described by the vendor as the first CDP on the market, gives it one of the longest track records and largest customer bases in this category.
- Pricing: Quote only. Not published; every plan is quoted after a sales conversation. Free plan: none stated.
- Best for: Marketing operations teams that want data collection, consent and audience activation without engineering support
- Strengths: Tag management; AudienceStream customer data platform; Consent management.
Where it falls short
No pricing is published anywhere, so a buyer cannot size a likely deal without a sales call.
Wrong for
A technical team that wants the whole customer profile and identity graph to remain inside its own warehouse, since Tealium's Snowflake Native App builds audiences in Snowflake but activation and profiles still run through Tealium.
Visit Tealium →
#10 Twilio Segment
The default CDP pipeline, acquired by Twilio for $3.2B · United States · segment.com
550+ pre-built destinations Acquired by Twilio for $3.2B (2020) Free entry tier
Segment solved event collection first and set the conventions most of the rest of this category still follows, which is why engineers already know its API without training and why its 550+ pre-built destinations cover most of the tools a marketing stack uses, though Tealium and Piwik PRO now list larger integration counts.
- Pricing: Free + paid tiers. Free plan: up to 1,000 monthly tracked users at $0. Free plan: free plan.
- Best for: Teams that want one SDK feeding a large catalogue of pre-built destinations
- Strengths: Event collection via a single SDK; Identity resolution (Unify); Audience segmentation and activation (Engage).
Where it falls short
Pricing by tracked user punishes a high-traffic consumer product with many anonymous visitors who never convert, and the full CDP tier (Unify, Engage, Protocols) is quoted rather than published.
Wrong for
A high-volume consumer business that wants to keep a close eye on cost per tracked profile, since Segment's per-user pricing model scales with traffic rather than budget.
Visit Twilio Segment →
#11 Salesforce Data 360 (formerly Data Cloud)
The profile layer for organisations already running Salesforce · United States · salesforce.com
Salesforce-native Consumption-based pricing Enterprise scale
Data Cloud, which Salesforce now sells as Data 360, makes most sense as a decision about the platform rather than the category: if CRM, service and marketing are already Salesforce, unifying customer profiles anywhere else means integration work an organisation can avoid.
- Pricing: Free + paid tiers. Flex Credits at $500 per 100,000 credits. Free plan: free plan.
- Best for: Organisations whose marketing, sales and service already run on Salesforce
- Strengths: Salesforce-native customer profile unification; Consumption-based real-time processing; Cross-cloud activation (Marketing Cloud, Service Cloud, Commerce Cloud).
Where it falls short
List prices for credits and profiles are published, but consumption across Flex Credits, storage and add-ons is difficult to forecast, and the free allowance is only open to existing Salesforce customers, so the true cost is rarely visible until after a quarter of usage.
Wrong for
A company with no existing Salesforce investment, since Data Cloud's value is concentrated for organisations already inside that ecosystem.

#12 Adobe Real-Time CDP
The profile and audience layer inside the Adobe marketing stack · United States · business.adobe.com
Adobe Experience Platform-native Real-time profile processing Enterprise / partner-led implementation
Inside the Adobe stack, Real-Time CDP is the profile layer everything else reads from, and for a large consumer brand already committed to Journey Optimizer the integration is worth real money. Judged on its own, it is the heaviest product on this list to implement.
- Pricing: Quote only. Not published; every deployment is quoted per organisation. Free plan: none stated.
- Best for: Enterprises that already run Adobe Analytics and Journey Optimizer
- Strengths: Real-time customer profile unification; Adobe Experience Platform schema and data model; Cross-channel audience activation.
Where it falls short
Implementation requires Adobe partner expertise, specialists are scarce and expensive, and the product is very costly to run outside the wider Adobe Experience Platform commitment.
Wrong for
A mid-market buyer with no existing Adobe products or implementation partner, since Real-Time CDP is built to extend an existing Adobe deployment rather than stand alone.

Questions and answers
What is the best customer data platform software in 2026?
Zeotap ranks first of 12, best for teams that already run Snowflake and want the CDP inside their own warehouse. mediarithmics is second (publishers and consumer brands planning their personalization and monetization strategy around the end of third-party cookies) and Spotler Activate third (ecommerce teams wanting one Dutch vendor for the CDP and, if needed, the rest of the Spotler Group's email and automation stack). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Which of these vendors are genuinely EU-headquartered?
Five: Zeotap (zeotap GmbH, Berlin, Germany), mediarithmics (Paris, France), Spotler Activate (Spotler Group, Netherlands), Commanders Act (Fjord Technologies, Paris, France) and Piwik PRO (Piwik PRO S.A., Wrocław, Poland).
Is Bloomreach a European company?
Not today. Its CDP product, Bloomreach Engagement, began life as the Slovak company Exponea before Bloomreach acquired it in 2021, and that is the European part of its history.
Which vendors publish real pricing, and which are quote-only?
Four of the twelve: RudderStack (a perpetual free tier at 250,000 events a month, Growth from $265 a month at 1 million events), Twilio Segment (free up to 1,000 monthly tracked users, Team from $120 a month, quoted pricing for Business and CDP plans), Piwik PRO (Business from €36 a month with a capped CDP allowance, Enterprise from €366 a month, plus a 30-day free trial) and Salesforce Data 360 (list prices for Flex Credits and profiles).
Is there a free customer data platform tool on this list?
RudderStack has a genuine perpetual free tier at 250,000 events a month, and Twilio Segment has a free plan up to 1,000 monthly tracked users.
Which vendors are dominant, established platforms rather than smaller challengers?
Tealium, Twilio Segment, Salesforce Data Cloud and Adobe Real-Time CDP are the four vendors on this list with the clearest market dominance and name recognition.
Is mParticle still an independent company?
No. mParticle completed a merger with Rokt and now operates and is sold as "mParticle by Rokt." The product continues to be marketed around mobile-first identity resolution and data governance, but a buyer evaluating it should confirm the current roadmap and support structure under its new ownership rather than assume it is unchanged.
What happened to Squeezely?
Squeezely was a standalone Dutch ecommerce CDP that has been folded into Spotler Group, a Dutch marketing-technology group, and renamed Spotler Activate.
Can a customer data platform run inside my own data warehouse?
Two vendors on this list support that model fully.
Which vendor is built for a world without third-party cookies?
mediarithmics, a Paris-based CDP built around cookieless identity resolution and audience monetization from the outset rather than a cookie-era product with a cookieless mode added afterwards.
Is there a fee to be listed in this ranking?
Visibility in this ranking can be paid for. Payment can move a vendor's position within the shortlist; it never adds a vendor that doesn't belong here and never changes a word of a review.
How often is this ranking updated?
Whenever a fact underneath it changes: a pricing update, an acquisition, a rebrand or a product that stops being maintained.
