Company Overview

RTB House is a next‑generation performance demand‑side platform (DSP) that uses proprietary Deep Learning AI algorithms to help brands grow. Founded in 2012 and operating in over 90 markets, it embraces first‑party advertising, continuous innovation and offers end‑to‑end Deep Learning‑powered AdTech products and solutions to maximize conversion and drive new customer acquisition.

Our infrastructure processes over 26 million HTTP requests per second and runs across four global data centers (EU, APAC, US East, US West), powered largely by open‑source technologies and modern infrastructure automation.

The Network Infrastructure Team designs, builds, and maintains the global network that powers RTB House’s platform, managing hundreds of switches and routers across data centers, developing network automation tools, and ensuring reliability, low latency, and scalability.
