Our clients & success stories

We work for companies that want to build and scale digital products and business models.

What we've achieved with our clients, in numbers and case studies.

Industry expertise

We know how buyers decide in ten industries

Since 2006, we've worked for retailers and brands, banks and insurers, travel providers, telecommunications companies, B2B providers and charities. Every industry decides differently. People book a cruise differently than a mobile plan. A donation follows different motives than a shoe purchase.

The psychology behind it is the same everywhere, though. People buy when an offer meets their motive and nothing makes them uncertain. We bring that knowledge from more than 300 client projects. Last year alone, we ran more than 275 experiments. That's why we don't start from zero in your industry.

Good reasons to work together

What sets konversionsKRAFT apart?

Our services

How can we help you
accelerate your digital growth?

Four services are behind the results above. We combine them based on your goals and your team's maturity.

Conversion optimization

We find out why customers buy or drop off, test solutions with A/B tests and implement what works.

Personalization

We recognize which customer type is on your site right now and show them the arguments that convince them. From the first test to a full program.

Redesign validation

Three out of four companies are unhappy with their redesign. We test your redesign step by step before it goes live.

Customer retention & loyalty

Discounts don't build lasting loyalty. We develop mechanics that turn a purchase into a habit, and we measure them by repeat purchase rate and contribution margin.

What matters to us: A growth mindset.

Most people associate a growth mindset with practices like growth hacking. But a growth mindset isn't limited to business goals. It's about understanding challenges at their core and turning that knowledge into results. The mental focus isn't on conditions, restrictions or bottlenecks, but on discovering optimization potential and understanding customers and their behavior.

Does our way of thinking resonate with you? Then we should work together.

Send us a no-obligation inquiry and tell us how we can support you on your mission. We'll get back to you within 48 hours.
