About the company

RZR is a growth marketing intelligence platform that acts as a DSP to unify and optimize advertising across mobile, retargeting, and Connected TV. Its system uses a proprietary neural architecture to analyze billions of signals in real time and predicts a user’s lifetime value before bidding on an impression, aiming to optimize for ROAS and long-term retention rather than just installs. The platform differentiates itself with AI-driven LTV prediction, cross-channel integration, and a single connected performance system supported by global data centers for brands in gaming, retail, and entertainment. Its goal is to help brands scale marketing effectiveness across channels through smarter bidding and attribution, building on its relaunch from Aarki in 2024 under CEO Aman Sareen.

Aarki rebrands as RZR, expanding into cross-screen performance platform processing 6M queries per second

Aarki, a performance marketing platform with over a decade of mobile advertising experience, has rebranded as RZR. The new identity reflects the company's expansion into a connected, cross-screen performance system that optimises user acquisition, retargeting, connected television and influencer campaigns. RZR's platform processes over 6 million queries per second and now serves brands across gaming, food and beverage, consumer apps, retail and entertainment. The company operates through proprietary neural architecture that treats all digital advertising channels as one connected system rather than siloed tactics. The rebrand follows significant investment in cross-screen measurement and a push into connected television as a performance channel. RZR now uses OEM data partnerships to target CTV audiences using behavioural signals whilst measuring mobile outcomes like installs and return on ad spend. The company operates offices across San Francisco, New York, London, Bangalore, Beijing, Manila and Seoul.
