We were extremely surprised by the figures
"The results were so good that I was suspicious, but I checked and they were right: defaults went from 33% to 13% in one market, from 37% to 19% in another. I don't know anyone who does it the way 4kst does, with this degree of personalization and evolution."

4kst gives me the exact remedy for my illness
"The score isn't off-the-shelf, it's personalized, thought out and specific. The model is developed using our data and not just market data. It's more niche. 4kst gives me the exact remedy for my illness. It is 4kst that is leading to a reduction in our default rates. We've already achieved a 30% reduction. To improve this figure we need to cut credit, but we can't make the business unviable."

The 4kst model brought personalized decision-making
"We used to do the analysis manually. My pain was to have a robust score that took into account all our particularities: my portfolio, the history of clients and their risk ranking, where I am economically inserted, the 9 companies in the group and the various products involved. The 4kst model provided personalized decision-making, which was very important!"
