Sounder

Niche contextual analytics provider for podcast advertising, acquired by Triton Digital to enhance its audio ad targeting infrastructure

Sounder is an AI-powered, end-to-end audio intelligence platform that brings together publishers, brands, agencies, ad tech marketplaces, and data partners to reshape how audio content is discovered, monetized, and optimized.¹ Its Audio Data Cloud enables large publishers to perform brand suitability analysis, topic analysis, content summarization, and dynamic segmentation.² On the targeting side, Sounder's True Topic targeting surfaces contextually relevant conversations at a granular level beyond assigned show genre, with its AI pinpointing podcast topics at the marker level to align ads with the most relevant content and audience.³ Clients can export podcast data from Sounder's Audio Insights dashboard into their existing workflows, and can also use the platform to verify active campaigns and validate media plans using brand suitability and contextual targeting criteria.⁴ Sounder has established strategic partnerships — including one with Magellan AI — to provide advertisers with comprehensive post-campaign measurement alongside verification of ad placements in brand-safe and suitable audio content. iHeartMedia, which has made a strategic investment in Sounder, was the first to deploy Sounder's AI and ML technology for episode-specific brand safety assurance at scale.^1,5 Source 1: magellan.ai — Strategic partnership for podcast brand safety Source 2: iheartmedia.com — iHeartMedia Partners with Sounder to Launch Best-in- ...
