MediaJel sells programmatic advertising into regulated industries, cannabis, alcohol, gaming, politics, where the mainstream ad networks will not go and where attribution is legally constrained rather than merely difficult.
The tracker is the instrumentation layer underneath that: the pixel and tag infrastructure that turns ad delivery into attributable events, feeding a clickstream pipeline into a warehouse. It went out across the client base and became a seven-figure revenue line on its own.
The work either side of it was the same shape at larger scale, Snowplow ETL pipelines on Kubernetes, a Snowflake warehouse, and later a migration of those pipelines onto ClickHouse that cut the cloud bill by ninety percent.
