What Justtag Group does

Justtag Group is a Polish data-as-a-service and marketing platform headquartered in Warsaw that provides AI-driven advertising targeting, retail media, and cross-channel campaign analytics to enterprise brands. The company combines online behavioral data from 25 million internet users, offline location data covering 5 million Poles, and transactional data from 11 million consumers across 72,000 retail points to power precision marketing campaigns, claiming reach of 85% of Polish internet users. Its core product portfolio includes Kampanie JUSTTAG (campaign management across Display, Video, Rich Media, and Native), Retail Media, Targetowanie (AI-powered targeting via PersonAi), Drive2Store (offline attribution), and Analityka (analytics), all built on proprietary technologies including JustID for cookie-free, GDPR-compliant user identification and Drive2Store's 2-meter-accuracy foot traffic measurement. The platform integrates online and offline consumer data into unified behavioral profiles, enabling clients to verify advertising-driven in-store visits rather than relying on third-party cookies, and operates within the IAB Europe Transparency & Consent Framework.

The company pursues an enterprise field sales motion with custom quote-based pricing and multi-year contracts, targeting major consumer brands and retail chains. Notable customers include Samsung, Disney, Electrolux, Philips, Volkswagen, Lotte, Bauer Media Outdoor Poland, and Continental Opony Polska, with strategic retailer partnerships including Żabka for first-party purchase data and Audience Solutions S.A. for cross-channel identity graph stitching. Revenue streams are generated from data-driven marketing services and retail media partnerships.

Justtag has executed an acquisition-led growth strategy: in November 2023 it acquired Finnish data provider Relevant Audience to enter the Scandinavian and Baltic markets (Finland, Sweden, Denmark, Norway, Latvia), and in June 2024 it acquired Polish native and mobile advertising network Adrino, adding a 20+ person team and mobile-first inventory. The company is led by CEO Tomasz Machała with Adam Sawicki as Chairman, Anna Kowalczyk as Chief Growth Officer, and Tomasz Mielcarz as CTO. Justtag operates as Justtag sp. z o.o. (KRS 0000463888), a privately held Polish limited liability company with no disclosed institutional investors beyond an early 2019 investment from Hubraum.

Broad incumbents

• Nielsen: Global media and audience measurement incumbent providing cross-channel attribution and ROI analytics. Comparable to Justtag's analytics and Drive2Store offerings as a large-scale measurement alternative for enterprise advertisers.
• Criteo: Global commerce-media platform operating the Criteo Retail Media Network with shopper data and retail-media monetization. Overlaps with Justtag in connecting ads to commerce outcomes, but at global scale across open web rather than a single market.
• The Trade Desk: Leading global independent demand-side platform with growing retail-media and identity (UID 2.0) offerings. Comparable as a buy-side platform that competes for the same enterprise advertiser budgets and is investing heavily in cookie-less identity.
• Quantcast: Audience intelligence and programmatic advertising platform using AI on first-party data. Comparable in combining behavioral data with AI-driven targeting and measurement for brand and performance campaigns.

Direct peers

• RTB House: Warsaw-headquartered, AI-driven performance retargeting and personalized marketing platform. Directly comparable as a Polish-rooted ad-tech player using deep learning on behavioral data to deliver measurable campaign outcomes for enterprise brands across EMEA.
• Synerise: Polish AI marketing automation and behavioral-data platform serving enterprise retail and e-commerce clients with audience targeting, recommendations, and campaign analytics — a directly comparable CEE-rooted data + AI marketing stack.
• QuarticON: Polish AI-driven personalization and recommendation platform for retail and e-commerce. Comparable as a CEE-based company applying AI to transactional and behavioral data for marketing and merchandising use cases.
• Cuebiq: Location intelligence and foot-traffic measurement platform that connects ad exposure to in-store visits — directly analogous to Justtag's Drive2Store, including its reliance on consented location signals under GDPR/CCPA frameworks.

Others

• Lotame: Global data-management platform and data-collaboration infrastructure provider. Adjacent to Justtag's data layer (PersonAi, Audience Solutions integration), enabling audience targeting and identity in a privacy-compliant way.

Emerging players

• LiveRamp: Data connectivity and identity-resolution platform enabling cookieless, people-based marketing. Closely comparable to JustID's identity thesis, but at cross-industry enterprise scale rather than a regional Polish/Czech stack.
