Strategic innovation cycle for

predictable growth in e-commerce

Case Study

Strategic business optimization through efficient personalization

As it transformed from a traditional catalog business into an e-commerce player, Arnulf Betzold GmbH faced the challenge of developing innovative online solutions without increasing product development costs. Betzold's secret to success was designing a personalization feature aligned with validated customer needs. Within a few weeks, the value showed up in revenue, registrations and sales. The Agile Growth Process™ made growth controllable.

Challenges and solution

The challenge: aligning innovation consistently with the customer

For 50 years, Arnulf Betzold GmbH has been the comprehensive point of contact for learning and teaching materials. Today, the established family business's range includes more than 100,000 items in its online shop, including comprehensive logistics. The digital shift away from a pure catalog business has grown into a successful hybrid of catalog and online retail.

Because digital transformation is also strongly influencing the education sector, Betzold wanted to develop its competitive advantages in e-commerce strategically while keeping product development costs from getting too high. It was important to Betzold to have a partner who develops innovation-driven measures in an agile way and aligns them consistently with customer needs through data-driven analysis and the application of consumer psychology. Broad digital marketing know-how, comprehensive technical support and interdisciplinary teams were meant to ensure that innovation within the company itself is strengthened as well. Looking ahead, it was also essential to understand its own target groups even better in order to increase sales, retention, loyalty and an improved customer experience digitally.

The solution: active personalization in a unique IT structure

Betzold's secret to success was designing a personalization feature aligned with validated customer needs, one that quickly reflects its value in revenue, registrations and sales in practice. That is why the innovation was developed as a minimum viable product. The MVP made sure the necessary functionality was delivered with the least possible effort.

Actionable feedback was then collected in live operation. All functionalities developed can be integrated through the infrastructure konversionsKRAFT created without additional IT effort. This essential technical advantage enables growth as soon as an innovation idea stands out through increased revenue in an A/B test. That's how controllable growth works.

Implementation in practice

Strong growth hypotheses as the result of systematic research into the customer experience.

We drew on existing data and new information from onpage surveys. It was important to find out how satisfied users are with the product segments on offer, in order to derive new ideas and hypotheses.


Agile Growth Process for predictable growth.

konversionsKRAFT used its own Agile Growth Process™ for Betzold. It shows which experiments answer rather tactical questions and which investigate growth-relevant principles. Through the three-stage process, new ideas can be put through success measurement and evaluation early on. As soon as a hypothesis can be linked to a company goal, the foundation is laid for turning insights into real growth. That is why we derived hypotheses for improving churn management and customer understanding, and evaluated new innovation and personalization measures. Looking ahead, the aim was to understand target groups better in order to increase sales, retention, loyalty and the customer experience.

konversionsKRAFT Agile Growth Process™

Concept success through consumer psychology.

The combination of technical innovation, consumer psychology and measurability, paired with the certainty that an innovation idea can be evaluated quickly, helps improve the online shop's offering further. Using consumer psychology principles, we developed a first MVP for a personalized shop area that covers the necessary functionality with the least possible effort.

High-impact testing and business optimization within a few weeks.

Agile development made it possible to create the concept and the shop module in one week each. For this, konversionsKRAFT used a unique technical framework that let Betzold bring the innovation live in the shop without major IT effort and run first success measurements. All the data generated was available across departments, was fed into internal decision-making and allowed the functionality to be optimized iteratively. This new kind of personalization could only come about because the innovation idea was backed by consumer psychology principles, data and testing. The result for Betzold is what we call high-impact testing for strategic business development.
