Justtag Group

The company operates a data‑as‑a‑service and adtech infrastructure model. It aggregates online behavioural, demographic and offline micro‑location signals into a central data management platform and identity graph. From this, it creates pre‑built and custom audience segments, attribution datasets and analytics outputs.

Value is created for advertisers and media agencies through more precise audience targeting, cross‑device identity resolution and measurement of offline visits and campaign impact. Publishers and app partners gain tools to monetise their first‑party and location data via integration into the platform’s audience catalogue. Revenue is generated by selling access to segments and data (via DSP integrations and direct licensing), and by charging for analytics, measurement and identity‑graph services tied to campaigns and publisher integrations.

Justtag is a Poland-based advertising technology and data company focused on audience data, identity resolution and campaign measurement, primarily in Central and Eastern Europe and the Nordics. It operates a large data management platform that profiles tens of millions of users daily, combining online behaviour, demographic data and offline micro‑location signals gathered via Wi‑Fi and partner apps.

The company generates revenue by licensing audience segments and data enrichment services to advertisers, agencies and platforms, and by providing identity-graph, analytics and attribution solutions. Its data is activated through major demand-side platforms and adtech partners, and it also supports publishers and app partners in monetising first‑party and location data via shared segment sell‑throughs and measurement services.
