Zefr Tech Stack

Brand safety and measurement platform for social video advertising

Advertising Services Los Angeles, CA 201–500 employees Founded 2009 Privately Held

Zefr operates a technology stack built for programmatic video and brand verification across Meta, TikTok, and YouTube — anchored on Salesforce, Snowflake, Kafka, and dbt for data pipeline automation. The hiring mix is tilted toward data (3 roles) and marketing (4 roles), with engineering (2 roles) a distant third, reflecting a business model centered on campaign execution and client onboarding rather than core product development. Active pain points reveal operational friction: manual reporting overhead, client onboarding delays, and compliance gaps in pharma advertising — all addressable through internal tooling, not platform innovation.
