Case Study: Pre-owned luxury marketplace Vestiaire Collective achieves 82% translation cost savings and near-real-time product translations with Google Cloud Platform

Vestiaire Collective Pre-owned luxury site saves 82% on translation

Vestiaire Collective is a Paris-based global marketplace for authenticated pre-owned luxury fashion with over five million members. To connect buyers and sellers across countries it needed fast, reliable translation of 3,000–4,000 daily product descriptions; its previous human-translation provider cost about €500,000 a year and caused multi-hour delays that slowed listings and risked lost sales.

Vestiaire implemented Google Cloud’s Translation API to auto-translate item descriptions from six languages into English, migrating in just two days. The result: translations now happen in near real time, upload time dropped from hours to almost immediate, translation spend fell by 82% (from €500k to roughly €90k), there’s no negative impact on conversion quality, and the company is expanding translations sitewide while exploring other AI tools.
