Best European Customer Data Platform Software

Looking for a GDPR-compliant alternative to Twilio Segment, Tealium or mParticle? European customer data platforms unify customer profiles from multiple systems and make the result available for segmentation and activation — while keeping the profiles themselves under EU jurisdiction. This is one of the thinner categories on this site: we found five genuinely EU-headquartered vendors after checking and rejecting several others, and we are saying that plainly rather than padding the list.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

How we review

Key takeaways

  • This is a genuinely thin category: five EU/EEA-headquartered customer data platforms passed our checks, and we rejected several other candidates rather than pad the list.
  • Only three of the five — Zeotap, mediarithmics and Spotler Activate — are CDP-first companies. Commanders Act and Piwik PRO sell their CDP as a module inside a broader tag-management, consent and analytics suite.
  • Zeotap ranks #1 for being the most CDP-first product here, and for running as a Snowflake Native App inside a customer's own warehouse rather than a separate vendor-hosted store.
  • Piwik PRO is the only tool in this category with a published starting price (Business from €36/month) and a free trial; the other four are entirely quote-only with no free tier.
  • Bloomreach, despite Amsterdam roots, is now genuinely US-incorporated and is not listed here; Occtoo and Contentsquare are genuinely European but are not CDPs by what they actually do.

Every European customer data platform reviewed

#1 Zeotap

Berlin, Germany Founded 2014 Quote-only, no published tiers No free tier or trial advertised

Best for: Teams that already run Snowflake and want identity resolution and activation inside their own warehouse rather than a second, vendor-hosted store

  • Operating company. zeotap GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. GDPR-compliant; deployable as a Snowflake Native App running inside the customer's own Snowflake instance
  • Source code. Closed source
  • Replaces. Twilio Segment, Tealium, mParticle

Zeotap (zeotap GmbH, Berlin, founded 2014) is the most CDP-first product in this category: identity resolution, audience enrichment and cross-channel activation are the whole company, not a module inside something larger.

Its most distinctive move is architectural — the product now runs as a Snowflake Native App, so the CDP logic can sit directly inside a customer's own warehouse rather than requiring a second, vendor-hosted profile store. The company went through a corporate restructuring in 2025 (a June spin-off of zeotap Data GmbH and a September change of chief executive) that is worth asking about directly during procurement, and it publishes no pricing anywhere on its site.

What stands out
  • CDP-first, not a module in a larger suite
  • Runs as a Snowflake Native App
  • Genuinely EU-based (Germany)
Where it costs you
  • No published pricing anywhere
  • No free trial advertised
  • 2025 restructuring and CEO change worth asking about

#2 mediarithmics

Paris, France Founded: not stated by the vendor Quote-only, no published tiers No free tier or trial advertised

Best for: Publishers and consumer brands planning their personalization and monetization strategy around the end of third-party cookies

  • Operating company. mediarithmics
  • Jurisdiction. EU (France)
  • Where the data sits. GDPR-compliant; no independently confirmed third-party certification
  • Source code. Closed source
  • Replaces. Twilio Segment, Tealium, mParticle

mediarithmics, registered in Paris, is built around real-time personalization and cookieless audience monetization from the outset rather than as a retrofit onto an older, cookie-era product. It recently merged with Easyence, a personalization and on-site search vendor, extending the product into on-site experience as well as the back-end data layer. Like most of this category, pricing is not published and no free trial is advertised.

What stands out
  • Built cookieless-first
  • Data unification plus audience monetization
  • Easyence merger adds on-site personalization
Where it costs you
  • No published pricing anywhere
  • Smaller international brand recognition than the US incumbents
  • Easyence merger makes the near-term roadmap harder to read from outside

#3 Spotler Activate

Netherlands Founded: not stated by the vendor (as Squeezely) Quote-only, no published tiers No free tier 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

  • Operating company. Spotler Group
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. GDPR-compliant; no independently confirmed third-party certification
  • Source code. Closed source
  • Replaces. Twilio Segment, Bloomreach, BlueConic

Spotler Activate is the current name for what was, until recently, sold as a standalone product called Squeezely: an ecommerce-focused CDP that unifies customer and behavioural data into segments and real-time triggers.

The Squeezely brand has been retired and the product folded into Spotler Group, a Dutch marketing-technology group whose other products cover email marketing and automation. Online reviews or case studies still published under the Squeezely name describe the same underlying product. Pricing is not published and no free tier is advertised.

What stands out
  • Purpose-built for ecommerce
  • Part of a larger Dutch marketing-technology group
  • Genuinely EU-based (Netherlands)
Where it costs you
  • Rename from Squeezely makes older reviews unreliable
  • No published pricing or free tier
  • Same product-independence question as any recently-acquired vendor

#4 Commanders Act

Paris, France Founded: not stated by the vendor Quote-only, no published tiers No free tier or trial advertised

Best for: European marketing and data teams wanting consent, server-side tag collection and the CDP profile from one French vendor

  • Operating company. Fjord Technologies (trading as Commanders Act)
  • Jurisdiction. EU (France)
  • Where the data sits. GDPR-compliant; EU-hosted
  • Source code. Closed source
  • Replaces. Twilio Segment, Tealium, mParticle

Commanders Act, the trading name of Paris-registered 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 vendor. In October 2023 the company acquired Adloop, an ad-optimisation product, making the CDP one of three product lines rather than the whole company. No pricing is published and no free trial is advertised.

What stands out
  • Tag collection, consent and CDP from one vendor
  • Genuinely EU-based (France)
  • Adloop acquisition adds ad-spend optimisation
Where it costs you
  • No published pricing anywhere
  • No free trial advertised
  • CDP is one of three product lines, not a specialism

#5 Piwik PRO

Wroclaw, Poland Founded 2013 Business from €36/month; 30-day free trial No permanent free tier for the CDP module

Best for: Organisations that want analytics, consent management and a CDP module from one EU vendor with published pricing

  • Operating company. Piwik PRO S.A.
  • Jurisdiction. EU (Poland)
  • Where the data sits. EU-only data centres, no US transfers for EU customers
  • Source code. Closed source
  • Replaces. Twilio Segment, Tealium, mParticle

Piwik PRO is the least CDP-first tool in this category and the most transparent on price.

Its customer data platform capability is sold as one of four modules — alongside analytics, a tag manager and a consent manager — branded “Data Activation” rather than marketed as a standalone CDP.

It is also the only tool here with a published starting price: the Business plan runs from €36/month and includes a capped Data Activation allowance (300 profiles/month), with Enterprise tiers from €366/month and higher tiers quoted.

A 30-day free trial is available with no credit card required, though there is no permanent free tier covering the CDP module. This page covers Piwik PRO specifically as a CDP option; it is also reviewed in more depth on our Web Analytics category, which is its primary listing on this site.

What stands out
  • Only published pricing in this category
  • 30-day free trial, no credit card required
  • EU-only data centres, no US transfers
Where it costs you
  • CDP is one module in a four-part suite, not a specialism
  • Data Activation profile allowance is capped even on paid tiers
  • No permanent free tier for the CDP module itself

Why this category is thin, and what we rejected

Customer data platforms are a category dominated globally by US vendors — Twilio Segment, Tealium, mParticle, Amplitude, Salesforce Data Cloud and Adobe Real-Time CDP between them cover most of the market — and the EU/EEA alternatives are correspondingly few. We researched a longer list of candidates than the five listed here, and rejected several for concrete, checkable reasons rather than simply not finding them.

Bloomreach was founded in Amsterdam in 2009 and its CDP product, Bloomreach Engagement, began life as the Slovak company Exponea before being acquired in 2021. Despite that European history, Bloomreach's current legal headquarters is in Mountain View, California, and it operates as a US-incorporated company today. That disqualifies it from this page even though its product is a genuine CDP.

Occtoo (Malmö, Sweden) is genuinely EU-headquartered, but its own product positioning is a “Product Orchestration Engine” — closer to product information management than to customer data unification — so it does not belong in this category regardless of its EU ownership.

Contentsquare (Paris, France) is also genuinely EU-headquartered, but it is an experience-analytics platform — session replay, heatmaps and journey analytics — not a customer data platform in the sense of unifying and activating customer profiles across channels. Being a real European company was not, on its own, enough to qualify it.

We also checked and set aside a smaller Belgian and Italian vendor after finding either an opaque ownership structure or a product that had narrowed to a specific regional vertical, in both cases making an EU-alternative claim harder to stand behind than for the five tools listed above.

CDP specialists versus CDP-as-a-module

Of the five tools here, only three — Zeotap, mediarithmics and Spotler Activate — are CDP-first companies where the customer data platform is the whole product.

Commanders Act sells its Real-Time CDP alongside its own server-side tag manager and consent tooling, and Piwik PRO sells its CDP module (branded Data Activation) as one of four modules in a broader analytics and consent suite.

Neither approach is wrong, but they answer different questions: a buyer who wants a CDP specialist should lean toward the top three, and a buyer who wants consent, tagging and customer data unification from a single EU vendor has good reasons to look at Commanders Act or Piwik PRO instead.

Published pricing is rare in this category

Piwik PRO is the only tool on this page with a published starting price, and even that only covers a capped allowance of its CDP module before the higher, uncapped tiers become quote-only.

Zeotap, mediarithmics, Spotler Activate and Commanders Act publish no pricing at all — a pattern consistent with the CDP category globally, where even large US vendors like Twilio Segment and Tealium mostly move buyers to a sales conversation once volume exceeds an entry tier. Budget for a scoping call as part of evaluating any tool on this page.

How we selected and ranked these 5 tools

Every tool on this page is in the European Purpose directory, which means the operating company is established in Europe and we have verified that from the company's own legal or privacy pages, or an official company register, rather than from a marketing page. Tools headquartered outside Europe are not eligible, however good they are — this is the specific reason Bloomreach is not listed here.

  1. Genuine CDP fit (weight: 40%). We check what the product actually does — unifying customer profiles and activating segments — against the vendor's own documentation, not against how loosely the word “CDP” is used in its marketing. Occtoo and Contentsquare failed this test despite being genuinely European.
  2. Independence and specialisation (weight: 25%). Whether the customer data platform is the company's whole product (Zeotap, mediarithmics, Spotler Activate) or one module inside a broader suite (Commanders Act, Piwik PRO). We rank specialists above suites, all else being comparable, but do not exclude suites outright.
  3. Value and transparency (weight: 20%). Published pricing counts in a vendor's favour; quote-only pricing is recorded as quote-only rather than estimated. Piwik PRO's published entry price is the reason it is not ranked last despite the weakest CDP-only fit.
  4. Editorial review (weight: 15%). Three people touch every page: one writes it, a second edits it, and a third checks the compliance and pricing claims against the vendor's documentation. The weights above decide the order; a position is a ranking against the other European tools in this category, not an absolute score.

Vendor-reported outcomes — certifications, funding milestones, customer counts — are labelled as vendor claims wherever they appear on this page. We have not independently audited them. Read our full editorial process for how pages are re-verified.

Frequently asked questions

Zeotap ranks #1 in this directory because it is the most CDP-first product on this page — identity resolution, enrichment and activation are the whole product, and it can run as a Snowflake Native App inside a customer's own warehouse. mediarithmics and Spotler Activate are the other two genuinely CDP-first European vendors; Commanders Act and Piwik PRO are broader suites (tag management and consent, or analytics and consent) with a CDP module rather than CDP-only companies.

Because that is genuinely how many EU/EEA-headquartered customer data platforms exist that pass this site's ownership test. We researched and rejected several other candidates that are either not EU-headquartered (Bloomreach is now US-incorporated), not actually CDPs (Occtoo is a product-data orchestration tool, Contentsquare is an experience-analytics platform), or too thinly documented to verify. We would rather list 5 genuine European CDPs than pad the page with tools that do not belong here.

All five tools in this category are built as European alternatives to Twilio Segment, Tealium and mParticle. None of the five publishes pricing that covers the CDP feature specifically except Piwik PRO, whose Business tier (from €36/month) includes a capped amount of its Data Activation module; the other four are quote-only.

Mostly, you do not find out without a sales call. Piwik PRO is the only tool here with a published starting price (Business from €36/month, including a capped Data Activation allowance; Enterprise tiers from €366/month, higher tiers quoted). Zeotap, mediarithmics, Spotler Activate and Commanders Act are all quote-only, with no published tiers.

Not a permanent free tier. Piwik PRO offers a 30-day free trial (no credit card required) rather than a free plan; the other four vendors advertise no free trial or free tier at all.

Zeotap, mediarithmics and Spotler Activate are CDP-first: the customer data platform is the whole product. Commanders Act sells its CDP alongside its own server-side tag manager and consent management tooling, and Piwik PRO sells its CDP module (branded Data Activation) as one of four modules in a broader analytics, tag manager and consent suite. Neither is a bad product for it, but a buyer wanting a CDP specialist should weigh that difference.

mediarithmics, a Paris-based CDP built around cookieless identity and audience monetization from the outset, rather than a cookie-era product with a cookieless mode added afterwards.

Zeotap is the one tool in this category available as a Snowflake Native App, meaning its identity resolution and activation logic can run inside a customer's own Snowflake instance rather than copying customer data into a separate vendor-hosted profile store.
