How Wix's AI Agents Stay Ahead of the Rest | Life Is But A Stream

Real-time data and AI are converging—and companies that have already solved the data pipeline problem are pulling ahead fast. Wix processes over 40 billion interactions every day across hundreds of millions of websites, and the architecture behind that scale didn't happen by accident. It was built, lane by lane, around the principle that your upstream data must be at least as fast as your fastest use case.

In this episode, Josef Goldstein, Head of R&D for the Big Data Platform at Wix.com, joins Joseph Morais to unpack how Wix evolved from a batch-based Hadoop architecture to a fully streaming-first platform on Confluent Cloud. The conversation covers Wix's multi-lane data architecture—from petabyte-scale data lakes to sub-second algorithmic decisions—how they approach data contracts and governance at distributed scale, and why Confluent Freight Clusters became a strategic unlock for cost and elasticity. Josef also explains how Wix is now wiring real-time stream processing directly into context layers for agentic AI systems.

You'll Learn:
How to architect a multi-lane data streaming system that serves use cases from sub-second ML inference to petabyte-scale analytics
Why upstream data quality, governance, and metadata are the real prerequisites for production-grade agentic AI
How Confluent Freight Clusters reduced costs and unlocked elastic scale for Wix's highest-volume, latency-tolerant data streams
