For the Customer Data Platform (CDP), the challenge was to develop an interactive mode in which a user (marketer) with no knowledge of HTML could easily specify what data to collect about site visitors.
A tool for digital marketers to setup website analytics
10438121
My client is a service for automating online marketing. This service allows e-commerce companies to build promotions based on the profile of a customer or website visitor, thus generating more accurate and targeted offers. Typically, such companies already have a large customer base in CRM systems, and this database had to be imported into the service in the form of visitor profiles for further analysis and processing. To facilitate the creation of imports, my team designed an interface in the form of a chatbot that accompanied the user through all stages of the import. The user needed to upload the file itself, and then specify how to fill in the visitor's profile by combining the profile attributes with the columns from the file. In this case, the interface can “help” the user by automatically matching the matched attributes. After completing the configuration, the user started the import.

This is the second time we use Keepitok and they delivered what needed to be done, in budget, in time. They didn't apply some "blanket recipe" to the project and tried to understand what we really needed and do the right thing to make this project successful. They didn't hesitate to challenge us on some of our assumptions, which is always appreciated. I would use them again and would recommend them.
