Cyber64 and Würth Croatia

SOLUTION

Cyber64 worked with Würth across three areas: platform stability and performance, release quality across web and mobile, and Adobe Target personalization

Strengthening platform stability and performance

Cyber64 optimized critical purchasing processes, improved ERP integration reliability and introduced better monitoring to identify and resolve issues faster. Frontend and backend improvements addressed performance bottlenecks, while the technical foundation was streamlined to make the platform easier to maintain and evolve.

Strengthening release quality across web and mobile

Cyber64 introduced a more structured release and quality process across the project. Automated tests were added for critical mobile journeys such as cart calculations, shipping logic and product validation, with failed tests blocking production deployment.

The mobile application was also improved across stability, search, product display and usability.

Building a secure personalization setup

Würth wanted to use Adobe Target to deliver more relevant product recommendations to different B2B customer groups. Cyber64 rebuilt the foundation for this capability, introducing proper consent management, securing the product data used for recommendations and establishing reliable audience segmentation and measurement. Würth can now deliver different recommendation experiences to their customers while measuring how each audience responds. The homepage recommendation experience was also modernized to support customer context, pricing, stock information, quantity selection and Add-to-Cart functionality.

RESULTS

Processing time for large B2B carts improved by almost 50%

Many Würth customers place complex, multi-product orders, making speed especially important in B2B purchasing.

Cyber64 reduced Add-to-Cart processing time by 1.5-2 seconds across key purchasing journeys. For large carts, response time within the recommendation component fell from 4.8 seconds to 2.56 seconds - an improvement of almost 50%.

For Würth's professional customers, this means less waiting while building complex orders and a smoother purchasing experience.

Homepage response became more than 18× faster

Initial server response improved from around 4 seconds to 220 milliseconds - more than 18× faster. Browser processing was also reduced by more than 80%, while the Google PageSpeed Performance Score increased by around 22%.

80% reduction in maintenance effort

As platform stability improved, maintenance processes became more efficient - the share of project capacity consumed by maintenance fell from 54.34% in April to 10.7% in June. That is an approximately 80% reduction - or around 5× less capacity spent on maintenance in just three months. This created significantly more capacity for new features, customer experience improvements and strategic ecommerce development

More reliable releases, with zero rollbacks

Würth and Cyber64 established a predictable monthly delivery cycle with quality checks before changes reach customers. During the observed period, no production release required a rollback or revert, and no critical production bugs were reported in connection with newly delivered features. For Würth, this supports the reliable introduction of new functionality in a business-critical ecommerce environment. Automated testing catches mobile issues before release Automated quality controls now cover 100% of mobile application pages and validate critical customer journeys before every production release. Failed tests automatically block deployment. This gives Würth a stronger safeguard against regressions and supports more reliable mobile development as the application continues to evolve.

Personalization became secure, measurable and actionable

Würth can now securely deliver personalized product recommendations to different B2B customer groups and measure how each audience responds. In the first measured month after launch, recommendations reached 6,510 visitors and achieved a 3.07% overall click rate. The data also showed clear differences between customer groups, where some groups achieved a 5.86% click rate - almost 2× the overall average. This gives Würth a clear benchmark for refining recommendations and expanding personalization across additional B2B customer groups.
