Custobar Joins Ilkka Group: Scaling EU Data Sovereignty & Omnichannel Firepower for European Retailers

Written by Aleksi Montonen | 2. September 2026

On August 31, 2026, Nordic marketing technology group Ilkka Oyj acquired 100% of Custobar Oy. This acquisition combines Custobar’s B2C Customer Data Platform (CDP) and omnichannel marketing automation engine with Ilkka’s European martech ecosystem (including WordPress/WooCommerce agency Evermade). The integration provides accelerated product development, enterprise stability, and 100% EU data sovereignty (GDPR-compliant hosting in Germany and Finland) for merchants running Shopware 6, Shopify, Magento, and WooCommerce across the DACH region and Europe. 

More Muscle, Zero Compromises on Data Sovereignty 

Running a omnichannel or pure ecom retail business in Europe means navigating a tricky landscape: consumers demand hyper-personalized shopping experiences, but privacy regulations (GDPR) and third-party cookie depreciation make US-hosted MarTech stacks increasingly risky.  

Custobar’s merger with Ilkka Oyj, a publicly listed European technology and marketing group, gives us serious extra muscle to scale our CDP and marketing automation platform while reinforcing what matters most: trust and local control.

Custobar has proven itself as a trusted CDP and marketing automation partner for leading retail and e-commerce brands across Europe and the DACH region. Their status as an official Shopware Technology Gold Partner perfectly highlights their strategic value—we are thrilled to welcome them into the Ilkka family and fully back their next phase of growth. -Olli Pirhonen, CEO of Ilkka Oyj 

 

 

What This Acquisition Means for European Retailers:

  • Backed by a European Publicly Listed Group: Joining Ilkka’s Data & Technology unit provides long-term financial stability and expanded R&D resources without relying on US venture capital cycles.

  • Strict European Data Sovereignty: All customer data remains stored and processed strictly within EU servers (Germany and Finland), offering complete legal compliance and immunity from international data transfer shifts.

  • Unified CDP + Activation: Unlike complex multi-vendor stacks that force you to glue a database to a separate sending tool, Custobar unifies customer data collection, natural language customer dynamic segmentation, built-in RFM segmentation, dynamic AI recommendations, and multi-channel messaging (Email, SMS, Whatsapp, Meta and Google Ads audience syncs) in one place.

 Operational Pain Point  Pure-Play E-Com Tools Custobar + Ilkka Group
"What did the customer buy in-store?" Blind spot. Store purchases live in a disconnected POS system. Full clarity. Real-time POS & Store UI integration enriches the 360° profile.
"Is our customer data legally safe in Europe?" Uncertain. Data relays through US infrastructure under changing privacy frameworks. 100% Guaranteed. Data is hosted in Europe (Finland/Germany) and is fully GDPR compliant
"Could foreign political shifts or non-EU vendors restrict access to our data?"    High risk. Exposed to the US CLOUD Act, foreign jurisdiction shifts, and third-party access risks.  Zero risk. 100% Finnish-owned, European stock-listed entity (Ilkka Oyj) operating strictly under EU laws.  
"Can store staff see online customer history?" No. Sales associates have zero access to e-commerce browsing or wishlist data. Yes. In-Store CRM UI gives floor staff instant customer insights on tablets/POS.
"How fast does Shopware 6 data sync?" Hourly batch updates or limited standard fields. Real-time event streaming for cart additions, wishlists, and order statuses. Also customer data is updated in real-time and custom fields can be brought into Custobar as well because of Custobar's open data schema.

This makes it effortless for staff to deliver personalized advice, update customer preferences, or sign up new loyalty members right at the till.
