Case Study: Vente‑Privee achieves full cross-device user-journey visibility with Adjust

A chat about user acquisition with Vente-Privee

Vente‑Privee, the original members‑only flash‑sales site with 35 million European members, moved from a web‑only model to launch a mobile app to meet rising demand for convenience. The team quickly discovered mobile behaved very differently from desktop: installs and in‑app behavior were a “black box,” making it hard to attribute installs, understand cross‑device purchase journeys, and measure the ROI of paid acquisition.

They integrated Adjust, assigned unique campaign codes, and merged mobile data with web analytics and their CRM, using deep links and Facebook Connect to pass tracking codes and improve UX. This enabled full cross‑device attribution, LTV tracking and channel ROI comparisons. As a result mobile now accounts for over 50% of web sales and 63% of 83.3 million monthly visits, mobile activity fuels many desktop purchases, and Vente‑Privee now allocates roughly 70% of marketing spend to acquiring and retaining mobile users.
