Have you ever wondered how Amazon recommends products you might be interested in purchasing?

Recommendation systems study patterns of behavior such as customers’ clicks on products and/or previous purchases to know what the customer of the online shop prefers from among a collection of products they either have an experience with before or not.


A large number of marketers segment their customers based on specific features and send a personalized email with different content to each segment.

Imagine taking personalisation to a level where each customer is a segment on his own and will receive special offers directed specially to him in the mailbox. 74% of mail recipients are annoyed when receiving irrelevant marketing content.


Any online shop that wants to stand out in the market should consider the implementation of machine learning!

STACC can help you with intelligent solutions like supply chain management, demand forecasting, machine learning pricing models, business process optimization, credit scoring, etc. Create personalized customer experiences and scale your business!

“In the field of art, it is often not possible to collaborate with professional IT people. It is an extremely mind-broadening experience. Additionally, STACC’s employees Karl-Oskar Masing and Dage Särg are extremely enthusiastic and creative partners. I look forward to the first performance of our common artificial intelligence on the stage.”
