Jobs at Djinni

We create solutions that put the client at the center of marketing. Marketing activities begin with an understanding of the client's needs and behavior, not with a product or campaign.

rich historical, real, and forecast customer data, AI-controlled orchestration of the client's multi-channel paths, and statistically reliable assessment of the impact of each marketing action.

This allows you to create personalized, efficient, and measurable marketing that is truly customer-oriented.
