RZR Becomes Top Open Internet iOS Retargeting Engine
RZR, formerly Aarki, has emerged as the No. 2 ranked iOS gaming remarketing platform globally in the AppsFlyer Performance Index 2026, trailing only Meta. This places RZR as the top-ranked iOS remarketing solution on the open internet, operating outside walled gardens. The company achieved this milestone less than a year after launching its iOS retargeting product, which relies on privacy-preserving machine learning instead of device identifiers. RZR processes over six million queries per second using its own data centres. The platform has delivered significant results for studios like Highcore Games, Playtika, and Zynga, with ROAS improvements up to 5x. The company, led by CEO Aman Sareen, rebuilt its technology stack after his appointment in 2023, and is now expanding its predictive engine beyond gaming to user acquisition, CTV, and consumer brands.
This news highlights a major advancement in post-ATT iOS retargeting, showing that open internet solutions can compete with walled gardens. It validates privacy-preserving ML approaches and could influence mobile marketing strategies across the industry.

AI Targeting Revolutionizes Mobile Gaming User Acquisition
An interview with Günay Azer discusses the rise of AI-driven targeting in mobile gaming and the three startups he helped found (Gamelight, Oroom, Catbyte). Gamelight operates a mobile marketing platform focused on rewarded user acquisition, building its own user base through game recommendation apps. Users earn rewards (e.g., Amazon gift vouchers, Google Play credits, or PayPal balances) and consent to data sharing, which Azer emphasizes is transparent and revocable. The platform collects demographic data and gameplay behavior, with AI processing this information in real time to tailor suggestions and improve ROAS. Azer argues traditional targeting is insufficient and that AI-based targeting, privacy-first marketing, and rewarded UA are transforming user acquisition, with Germany highlighted as a strong market. The conversation envisions future steps like hyper-personalization, predictive modeling, and context-aware targeting.
