The Perfect Customer Experience through Data Intelligence

CRM Consulting

Marketing is not about you liking your campaigns, your content, or your public presence. It is about your customers liking it. What good is the cleverest or most charming newsletter if nobody wants to read it? What good are 100 news leads every week if you don’t know what to do with the data? What you want is the right customer experience, and that is why CRM and marketing automation tools matter: As the perfect place to pool all of your customer data, insights, and intelligence.

Personalisierung & Recommendation Engines

We want to help you use data analytics to understand your customers and their behaviour better. Knowledge is power: The more you know about your customers, the better you can personalize and match their experience to their expectations.

Data/Web Analytics & Optimization

We can assist you in discovering more about your customers and their habits and preferences. You can tailor your offerings perfectly to their needs and expectations: Data and business analytics or A/B tests can pinpoint what you can improve for more revenue and a better conversion rate.


The right CRM system gives all parts of your business the access they need to the crucial customer data. It improves the flow of information and reduces the hassle of administration. You can collect, automate, and personalize all of the communication with your customers (offers, invoices, vouchers, orders, newsletters and more). The benefits for your people are obvious: More personal, appreciated relations with customers with less effort and lower costs.

Customer Service & Marketing Automation

It is all about customer centricity. A good CRM system goes a long way, but the real trick lies in using the data and insights you have to make your customers happier and more satisfied and to always offer them just the experience they want (and more). That is easier than you might think: The magic of data, personalization, and automation can ensure an impressive customer experience at any stage in the customer journey.
