Best European Customer Data Platform Software

#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 the CDP in their warehouse

• Operating company. zeotap GmbH (HRB 158127 B, Amtsgericht Charlottenburg)
• Jurisdiction. EU (Germany)
• Where the data sits. GDPR-compliant; deployable as a Snowflake Native App inside the customer's own Snowflake instance
• Independent checks. No independently confirmed third-party certification
• Source code. Closed source
• Replaces. Twilio Segment, Tealium, mParticle

Zeotap (zeotap GmbH, entered in the commercial register as HRB 158127 B at Amtsgericht Charlottenburg, Berlin, founded in 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 a broader suite of tag management, consent or analytics, which is how several other vendors on this page are built.

Its most distinctive move is architectural. The Composable CDP is available as a Snowflake Native App, so the CDP logic can run directly inside a customer's own warehouse rather than requiring customer data to be copied into a separate vendor-hosted profile store.

That matters most to a data team that has already invested in modelling customer tables in a warehouse and does not want a second system of record. Zeotap's public materials cite G2 High Performer recognition in the Enterprise CDP category for 2026 and a Google Cloud Partner designation.

The trade-off is transparency. Zeotap publishes no pricing anywhere on its site and advertises no trial, so a buyer cannot size a deployment without a sales conversation.

The company also went through a restructuring in 2025, with a June spin-off of a separate entity, zeotap Data GmbH, and a September change of chief executive, which is worth asking about directly during procurement. A small team that wants to self-serve a plan and see a number first will find this the least approachable of the specialists.

Standout feature. The only tool here that can run as a Snowflake Native App, keeping the CDP inside the customer's own warehouse.

#2 mediarithmics

Paris, France Quote-only, no published tiers No free tier or trial advertised

Best for: Publishers and brands planning for a cookieless future

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

mediarithmics is a Paris-registered customer data platform, with its address given as 3 rue d'Edimbourg, 75008 Paris. It is built around real-time personalization and cookieless audience monetization from the outset, rather than being a cookie-era product that gained a cookieless mode later, and that origin is its clearest difference from the older US platforms it is positioned against, such as Twilio Segment, Tealium and mParticle.

The pitch is to unify first-party customer data, build segments from it and activate those segments across channels, and, distinctively, to monetize audience data directly rather than only using it internally. That monetization angle suits publishers and consumer brands with large first-party audiences. The company has recently merged with Easyence, a personalization and on-site search vendor, which extends the product from the back-end data layer into on-site experience as well.

Like most of this category, mediarithmics does not publish pricing anywhere and advertises no free trial, so every deployment is scoped through a sales conversation. It is a smaller and less internationally recognised brand than the US incumbents, and the Easyence merger makes the near-term roadmap harder to read from outside. A buyer should ask what has been combined, on what timeline, and which parts of the earlier product line are being retired.

Standout feature. Audience monetization built into a CDP designed around a world without third-party cookies.

#3 Spotler Activate

Netherlands Quote-only, no published tiers No free tier stated

Best for: Dutch ecommerce teams wanting one vendor for CDP and email

• Operating company. Spotler Group
• Jurisdiction. EU (Netherlands)
• Where the data sits. GDPR-compliant
• Independent checks. 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 customer data platform that unifies customer and behavioural data into segments and real-time triggers for personalization, email and advertising. 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 marketing automation.

For a buyer the practical effect of the rename is twofold. The product itself continues largely unchanged, so any research, reviews or case studies published under the Squeezely name describe the same underlying product now sold as Spotler Activate. And a buyer already using or considering another Spotler product gets the option of a single Dutch vendor across CDP, email and automation, rather than three separate contracts and three separate data-processing agreements to manage.

Pricing is not published and no free tier is advertised; the vendor routes every enquiry to a demo or quote request. The founding year is not stated by the vendor under the Spotler name. This pattern, a smaller focused CDP absorbed into a larger regional marketing-technology group and renamed, is worth probing in procurement: ask how much of the original roadmap and support team survived the transition and where the product sits in the group's plans.

Standout feature. One Dutch vendor for ecommerce CDP, email and automation after the Squeezely rename.

#4 Commanders Act

Paris, France Quote-only, no published tiers No free tier or trial advertised

Best for: Teams wanting consent, server-side tagging and the CDP from one vendor

• Operating company. Fjord Technologies, trading as Commanders Act (SIREN 527 730 782)
• Jurisdiction. EU (France)
• Where the data sits. GDPR-compliant; EU-hosted
• Source code. Closed source
• Replaces. Twilio Segment, Tealium, mParticle

Commanders Act is the trading name of Fjord Technologies, a Paris-registered company (SIREN 527 730 782) that built its customer data platform outward from a server-side tag management business rather than starting from a blank profile store.

That history shapes the product: collection happens through the company's own Enterprise Tag Manager, consent state from its consent management layer travels with the data by default, and the Real-Time CDP sits on top to unify the resulting customer profile and push segments to activation channels.

In October 2023 the company also acquired Adloop, an ad-optimisation product, adding a third line to what is now a three-part suite rather than a CDP sold on its own. For a European marketing or data team the pitch is consolidation: one French vendor, one contract, and no seam between the consent banner and what the tag actually sends, which is a gap where compliance failures in multi-vendor stacks commonly hide.

The company does not publish pricing anywhere on its site, every plan is scoped through a sales conversation, and no free trial is advertised. Judged purely as a CDP, Commanders Act is less of a specialist than Zeotap or mediarithmics, because the customer-data layer is one of three product lines rather than the whole company. For a buyer who already wants server-side tagging and consent management from the same vendor, that breadth is the point rather than a distraction.

Standout feature. Consent state, server-side tag collection and the CDP profile sit with one French vendor.

#5 Piwik PRO

Wroclaw, Poland Founded 2013 Business from €36/month with a capped Data Activation allowance (300 profiles/month); Enterprise from €366/month; higher tiers quoted 30-day free trial, no credit card required; no permanent free tier for the CDP module

Best for: Organisations wanting analytics, consent and a CDP module 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 (Piwik PRO S.A., Wroclaw, founded in 2013) 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, branded Data Activation, alongside analytics, a tag manager and a consent manager, rather than marketed as a standalone CDP. It is reviewed in more depth on this site as a web analytics tool, which is its primary listing.

It is the only tool here with a published starting price. The Business plan runs from €36 per month and includes a capped Data Activation allowance of 300 profiles per month, with Enterprise tiers from €366 per 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 itself, so a buyer with a large profile base needs to work out which tier applies.

Data is held in EU-only data centres with no US transfers for EU-hosted customers, which is why its customers skew towards public administration, healthcare and finance, where that is a procurement requirement rather than a preference.

The trade-off against the CDP-first specialists is depth: the CDP is one module in a four-part suite and its profile allowance is capped even on paid tiers. For analytics, consent and a CDP from one EU vendor with published pricing, it is the most accessible entry point.

Standout feature. The only published CDP entry price in the category, with a 30-day trial and EU-only data centres.

#6 Celebrus

Sunbury-on-Thames, United Kingdom Founded 1999 Not published; demo and quote on request Not stated by the vendor; demo on request

Best for: Enterprises needing tag-free first-party data capture and identity resolution

• Operating company. Celebrus Technologies plc (Companies House 01892751)
• Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
• Where the data sits. Celebrus Cloud is a single-tenant virtual private cloud; AWS, Azure and Google deployment options stated
• Independent checks. Penetration testing to ISO 27001 standards stated; no ISO certificate named on the pages reviewed
• Source code. Closed source
• Replaces. Adobe Real-Time CDP, Amperity, mParticle

Celebrus is the product of Celebrus Technologies plc (Companies House 01892751, registered office in Sunbury-on-Thames), a company quoted on the AIM market of the London Stock Exchange and, according to its own about page, founded in 1999. It sells a digital data and identity platform that captures behavioural data from web and mobile channels without tags, resolves identity in real time and exposes the result through an API and batch connectors to warehouses and analytics platforms.

It describes itself as an AI customer data platform, and its own site compares it against Adobe, Amperity and mParticle, but its centre of gravity is the capture and identity layer rather than segmentation and campaign tooling. The same data model also feeds Celebrus Fraud, with behavioural biometrics, and Celebrus Analytics, so it is a data platform with several uses rather than a marketer-facing tool. Its anonymized collection mode captures data when visitors opt out of cookies.

Celebrus Cloud is a fully managed single-tenant virtual private cloud, with deployment options on AWS, Azure and Google, and the vendor says it tests to ISO 27001 standards without naming a certificate. No price is published and no self-serve trial is stated. The company lists a US subsidiary, Celebrus Technologies Inc. in North Carolina, alongside its UK parent, and as a UK company it is covered by the EU adequacy decision rather than being established in the EU.

Standout feature. Captures complete first-party behavioural data without tags and resolves identity in real time.

#7 Agillic

Copenhagen, Denmark Founded 1999 Not published; contact sales or book a demo Not stated by the vendor; demo on request

Best for: Nordic and EU marketing teams wanting CDP plus automation with an audit trail

• Operating company. Agillic A/S (CVR 25063864)
• Jurisdiction. EU (Denmark)
• Where the data sits. All data hosted in EU data centres; EU-based processing only
• Independent checks. Annual ISAE 3000 Type 2 audit by Deloitte; ISMS based on ISO/IEC 27001:2022 controls, data centres conform to ISO 27001; no ISO 27001 certificate for Agillic itself stated
• Source code. Closed source
• Replaces. Twilio Segment, Tealium, Bloomreach

Agillic A/S (CVR 25063864, Copenhagen) describes itself as a Nordic marketing automation and customer data platform. According to its own about page it was founded in 1999 and has been listed on Nasdaq First North Growth Market Denmark since 2018, which makes it one of the few vendors on this page with public financial reporting. Its named customers on the homepage are mostly Nordic, including retailers, a cultural institution and a football club.

The Agillic CDP can be used alone or as part of its marketing automation platform.

The model is built on profiles and events, with aggregated properties such as event counts, latest values, counts per topic and RFM scores, and a condition editor whose segment entry and exit triggers drive actions. Data comes in through API requests, custom endpoints that accept any incoming payload, and CSV imports, and goes out through prebuilt or low-code actions. The page does not explain how identities are matched.

On security, the vendor publishes an annual ISAE 3000 Type 2 report audited by Deloitte and states that production and customer data sit in Tier 3+ equivalent data centres inside the EU, with EU-based processing only. Its information security management system is based on ISO/IEC 27001:2022 controls and its data centres conform to ISO 27001; it does not claim an ISO certificate of its own. No price is published and the hosting provider is not named.

Standout feature. A listed Danish vendor that publishes an annual Deloitte ISAE 3000 Type 2 audit alongside EU-only hosting.

#8 Ometria

London, United Kingdom Founded 2013 Not published; demo on request Not stated by the vendor; demo on request

Best for: Retail and ecommerce brands wanting a retail-specific CDP with activation

• Operating company. Ometria Ltd (Companies House 08372083)
• Jurisdiction. United Kingdom (adequacy decision, outside the EEA)
• Where the data sits. Not stated by the vendor
• Independent checks. ISO 27001 and ISO 27701 listed among its security credentials; no certificate document published on the pages reviewed
• Source code. Closed source
• Replaces. Klaviyo, Bloomreach, Twilio Segment

Ometria Ltd (Companies House 08372083, London, incorporated in 2013) calls its product a customer data and experience platform, built specifically for retail brands. The data layer ingests from ecommerce platforms, data warehouses and ERP, websites, mobile apps, POS, loyalty and customer support systems, consolidates customer profiles, resolves identity across email, mobile and cookie data, including for anonymous visitors, and keeps a single record of marketing consent across channels.

The experience layer sits on the same profiles: real-time audiences, a broadcast builder, a cross-channel journey builder and delivery through email, SMS, ads and retargeting, mobile push, direct mail, in-store and customer service, and loyalty. Its AI layer, Architect AI, adds predictive attributes such as forecast next-order timing and VIP potential. The vendor lists ISO 27001 and ISO 27701 among its security credentials and says it supports both GDPR and North American requirements such as CCPA.

The retail focus is the point and the limit: a B2B or non-retail team will find less that fits. No pricing is published, there is no pricing page, and no self-serve trial is stated.

The company says it has about 200 clients, 150 staff and more than 250 million customer profiles, figures it reports about itself, and has raised more than $70 million. As a UK company it is covered by the EU adequacy decision rather than being established in the EU.

Standout feature. A retail-specific CDP and cross-channel orchestration layer on one set of profiles, with identity resolution for anonymous visitors.

#9 Voyado

Stockholm, Sweden Founded 2005 Fixed platform fee plus volume-based usage fee for email, SMS and other channels; amounts not published Not stated by the vendor; demo on request

Best for: Retailers wanting CRM, loyalty and product discovery from one Swedish vendor

• Operating company. Voyado AB (reg. no. 556787-0208)
• Jurisdiction. EU (Sweden)
• Where the data sits. Main processing takes place within the EU; some sub-processors process outside the EU/EEA under stated transfer tools
• Source code. Closed source
• Replaces. SAP Emarsys, Twilio Segment, Salesforce Marketing Cloud

Voyado AB (reg. no. 556787-0208, Stockholm) was founded in 2005 in Norrköping and now has more than 400 employees in Sweden, with offices in the UK, the Netherlands and Germany, according to its own about page. It sells what it calls an agentic CX suite for retail: customer engagement (CRM, email, SMS and RCS), loyalty, product discovery (site search, recommendations and merchandising) and retail media.

Voyado does not lead with the CDP label on its product pages, but its own knowledge hub pitches it against SAP Emarsys for omnichannel engagement and CDP use. The customer profile, consent capture and data-quality controls are what a retailer is buying, with in-store identification connecting purchases to the profile. It is deliberately retail-specific, and the vendor says it serves more than 500 retail brands across 100 markets.

Pricing has two parts, a fixed platform fee and a usage-based fee that scales with volume, with no amounts published. The agreement is governed by Swedish law. Main processing takes place within the EU, but some sub-processors process data outside the EU/EEA, in which case transfer tools such as the EU-US Data Privacy Framework or standard contractual clauses apply, as listed on its public sub-processor page.

Standout feature. A Swedish retail suite where customer profile, loyalty and product discovery share one data layer.

#10 Custobar

Espoo, Finland Founded 2014 Small plan from €548/month (up to 300,000 contacts; 20,000 contacts and a monthly email package included); Medium, Large and Enterprise on request Not stated by the vendor; demo on request

Best for: Retail and ecommerce brands wanting a CDP with marketing automation and EU data centres

• Operating company. Custobar Oy (Y-tunnus 2645106-1)
• Jurisdiction. EU (Finland)
• Where the data sits. Data centres in Finland and Germany, within the EEA
• Independent checks. GDPR compliance audited by a third party, as stated by the vendor; no ISO or SOC certificate named
• Source code. Closed source
• Replaces. Salesforce Marketing Cloud, Bloomreach, Klaviyo

Custobar Oy (Y-tunnus 2645106-1, registered in Espoo, Finland, in 2014) describes itself as a retail-focused CDP and marketing automation platform. Its story starts in 2014 with a founder who had implemented Salesforce in a record store and found it lacked offline data collection and point-of-sale usability. The vendor says it now has 300+ customers in eleven countries, a figure it reports about itself.

The platform covers a customer 360 view, segmentation and data management, then activation through email, two-way SMS, push, on-site banners and pop-ups, AI product recommendations, Meta custom audiences and Google customer match. It lists more than 70 integrations including Shopware, Shopify, Magento and WooCommerce. Pricing is published: the Small plan starts at €548 per month, includes 20,000 contacts and an email package, and is the choice for up to 300,000 contacts.

Its terms are governed by Finnish law with arbitration in Helsinki, and its data centres are in Finland and Germany. On 31 August 2026 the listed Finnish group Ilkka Oyj acquired 100% of the company, according to Custobar's own blog, so the direction of the product now follows that group. A third party has audited its GDPR compliance, but no ISO certificate is named.

Standout feature. A retail CDP with marketing automation in one licence, a published €548 per month entry plan and data centres in Finland and Germany.
