OpenX Tech Stack

Independent supply-side platform for programmatic ad exchanges

Technology, Information and Internet Pasadena, CA 201–500 employees Founded 2007 Privately Held

OpenX operates a supply-side platform (SSP) for publishers in programmatic advertising, with a polyglot backend spanning Java, Go, Erlang, Elixir, and Rust running on GCP + Kubernetes. The active project list reveals a company mid-pivot: while yield optimization and ad exchange features dominate, a significant thread of work targets connected TV (CTV) go-to-market and sales enablement — suggesting CTV is being positioned as a new growth vector. Pain points cluster around real-time scaling (low-latency integrations, deployment speed) and operational infrastructure (payroll compliance, cloud platform streamlining), indicating growing infrastructure debt as the platform scales.
