METRO wanted an internal activation mechanic that meets two goals at once: strengthening the internal sense of community as an employer brand and winning qualified employee contacts for internal newsletters and engagement communication. Classic email campaigns with no active employee interaction produce low opt-in rates and little emotional connection.

The operational requirement was a low threshold: the activation had to work with no app installation, no separate logins and no physical station logistics — distributed across a broad employee base at different locations. A central hardware activation at one place would have excluded a large part of the target group.

The communicative requirement was community visibility: the individual employee participation was to condense into an aggregated overall picture — a live mosaic showing the METRO community in a constantly updated form. Individual contributions were to be experienceable as part of the larger whole.

Lead time four weeks: two weeks for software configuration (UI branding in the METRO CI, overlay and filter curation, live-mosaic aggregation logic), one week for GDPR compliance review and newsletter opt-in mapping into the METRO marketing system, one week for internal communication preparation and employee onboarding.

No hardware logistics: the entire activation ran on the UpReach cloud infrastructure via the browsers of the employees' smartphones. The live-mosaic display was accessible via a separate browser link and could be embedded on internal screens, in break areas or in the intranet.

During the activation run, the cloud dashboard gave the METRO HR and marketing team real-time transparency on session volume, newsletter conversion rate, average interaction time and mosaic growth. After the activation ended, the final CSV export of all newsletter leads with complete opt-in documentation was handed over to the METRO marketing system.
