RTB House

Leading independent deep learning-powered retargeting platform, competing with Criteo and other DSPs with a privacy-first, cookieless-ready approach

RTB House is a Warsaw-based Polish adtech firm whose proprietary deep learning-powered demand-side platform helps brands drive conversions, acquire customers, and engage users across the purchase funnel, with operations spanning more than 90 markets and over 1,500 employees across 30+ offices worldwide.¹ Its end-to-end performance pipeline leverages dramatically more computational power than conventional machine learning models and is built around durable first-party data signals.² The platform can pinpoint where each user sits within the purchase funnel—awareness, consideration, or conversion—using self-learning algorithms that analyze not just click-through rates but also browsing behavior, product categories viewed, transaction methods, and search tactics, enabling highly personalized retargeting.¹ In 2026, the company extended its reach to smaller advertisers by introducing rtb.com, a self-serve retargeting platform aimed at small and midsize ecommerce brands.¹ RTB House has also expanded its footprint through subsidiaries, including Adlook, a media buying startup focused on CPG brand advertising, and SEM House, a search engine marketing agency.¹ Across all entities that process client data, the company has achieved ISO/IEC 27001:2022 certification, reflecting its commitment to rigorous information security management.² Source 1: wikipedia.org — RTB House Source 2: rtbhouse.com — About Us
