ZEFR

What ZEFR does

Zefr is a brand suitability and verification platform purpose-built for social video advertising. Its core product, the Classification Engine, applies a multi-modal AI model that ingests video frames, audio, speech, text, metadata, and contextual signals simultaneously to classify content at scale across YouTube, Meta (Facebook, Instagram, Threads), TikTok, Snapchat, Google Ads, and DV360. The platform delivers content-level brand safety and suitability, AI-generated content detection, brand misappropriation detection, viewability, and media quality measurement, with MRC-accredited methodologies on YouTube for both viewability/IVT (2025) and content-level brand safety and suitability (2026) — the first independent third party to achieve the latter.

Zefr monetizes through three primary streams: subscription-based measurement and verification (Brand Safety & Suitability, Viewability, AI-Generated Content, Brand Misappropriation), managed media services for end-to-end YouTube campaign execution at a single transparent fee, and data solutions distributed via a DV360 browser extension and platform-native integrations inside TikTok Ads Manager and Google Ads. Customers are Fortune 100 brands, sensitive-vertical advertisers (pharma, finance, kids), and major media agencies; multi-year contracts and enterprise field sales dominate the GTM. Operational footprint includes HQ in Los Angeles plus offices in New York, Chicago, London, and a Tel Aviv AI engineering team established through the 2022 acquisition of Adverif.ai.

In 2026 Zefr extended its product surface with Zain, an agentic hub offering the industry's first AdCP-based buying integration for YouTube and an MCP server that connects client AI agents to Zefr's data, positioning the company to evolve from passive measurement into agent-driven activation across social platforms.
