What NumberEight does
NumberEight is a London-based privacy technology company founded in 2018 that provides an ID-less audience intelligence platform for the advertising ecosystem. The company serves publishers, ad platforms, and brands by enabling audience targeting and content curation across mobile, podcasts, gaming, and connected TV (CTV) environments without relying on traditional identifiers such as cookies or mobile advertising IDs (MAIDs). Its core technology combines on-device artificial intelligence, federated learning, and zero-PII analytics to process user signals locally on devices, transforming anonymous behavioral, contextual, and sensor data into actionable audience segments with claimed 95%+ match rates across 200+ countries and 28+ languages.
The product portfolio is organized around two pillars: curation (Omnichannel Affinity Curation and Contextual Curation) and targeting (Live & Behavioral Targeting, Podcast Affinity Targeting, and Mobile Affinity Targeting). These are powered by three enabling capabilities—Affinity Audiences, Advanced Behavioral, and Deep Contextual—that use machine learning, natural language processing, and generative AI to interpret sensor data, content metadata, and behavioral signals. Distribution is primarily via SDK integration into customer apps and embedded partnerships with major adtech platforms including AdsWizz (AudioServe, AudioMatic DSP, AudioMax SSP, Simplecast) and The Trade Desk.
NumberEight operates a SaaS-style revenue model through SDK/platform licensing and data intelligence services to enterprise customers, with quote-based annual pricing. The company has raised approximately $5.67 million across disclosed rounds, most recently a $2.7 million Pre-Series A led by ACF Investors in January 2024 to fund US expansion and product development. Named customers include Southern Cross Austereo/LiSTNR, Yieldmo, McDonald's, Berocca, BBC Studios, Kic, and Adverty, with case studies demonstrating outcomes such as 15% CPM lifts, 130% ad spend increases, 58% brand preference boosts, and 71% listener action rates. The company is led by co-founders Abhishek Sen (CEO) and Chris Watts (CTO), with Emma Raz as Commercial Director.
