OpenSlate

A leading contextual intelligence and brand suitability solution for social video and CTV, now integrated within DoubleVerify's global verification platform

OpenSlate, now part of DoubleVerify following a $150 million acquisition completed in November 2021, is a leading contextual intelligence and brand suitability platform purpose-built for digital video advertising. The company's technology analyzes and classifies content across major social video platforms—including YouTube, Facebook, Instagram, and TikTok—as well as connected TV (CTV) environments, enabling brands and agencies to ensure their ads appear alongside content that aligns with their values and suitability standards. Founded in 2010 and headquartered in New York, OpenSlate built its reputation by developing one of the most comprehensive content classification systems in the industry, evaluating billions of pieces of video content against brand safety and suitability criteria. Its platform goes beyond simple keyword blocking to deliver nuanced, content-level analysis that helps advertisers make smarter targeting decisions while minimizing reputational risk. The acquisition by DoubleVerify was driven by a strategic desire to strengthen DoubleVerify's capabilities in CTV and social video—two of the fastest-growing segments in digital advertising. As part of DoubleVerify, OpenSlate's contextual targeting and suitability technology has been integrated into DoubleVerify's broader measurement and verification suite, extending its reach and scale across the global digital advertising ecosystem. The combined offering allows advertisers to not only verify ad delivery but also proactively plan and activate campaigns in contextually appropriate environments, reinforcing DoubleVerify's position as a comprehensive brand safety and media quality platform.
