WBD CTO Saxena outlines Max global DTC platform at Streaming Summit

Warner Bros. Discovery CTO Avi Saxena joined Streaming Summit chair Dan Rayburn on Tuesday April 21 to examine the engineering and business challenges of running a global direct-to-consumer platform at scale. The session covered HBO Max's international expansion, the localization requirements of serving multiple markets simultaneously, and how AI is being used inside live streaming delivery infrastructure — not in content creation pipelines.

The framing of the session positioned Max as a platform built for global scale from the outset rather than a US service being extended internationally. Saxena addressed the localization demands of diverse markets — language, regulatory compliance, content licensing boundaries, and latency requirements — as engineering constraints that shape the underlying architecture rather than features applied after the fact.

The AI discussion focused on infrastructure use cases: automated capacity management, delivery optimization, and quality assurance at scale. This aligns with the broader Streaming Summit theme that AI in the video stack is now operational, not experimental, and the questions have shifted to governance, cost, and reliability. For streaming operators planning global expansion, the WBD session provided a case study in what the engineering surface of a scaled international DTC platform actually looks like.
