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.

| 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. |

It provides native, plug-and-play integrations for Shopify, Magento, JTL-Shop and WooCommerce, alongside custom REST APIs for proprietary eCommerce platforms and ERP and POS systems.

Store staff can quickly scan a pass or search a profile at checkout to view the customer’s complete purchase history, online browsing behavior; campaigns, automations and transactional messages they received; and AI-powered product recommendations. This makes it effortless for staff to deliver personalized advice, update customer preferences, or sign up new loyalty members right at the till.
