NumberEight provides ID-less audience intelligence technology for digital advertising, serving publishers, ad platforms, sales houses, and agencies across podcasting, mobile, and connected TV (CTV). The company uses on-device AI, natural language processing, and machine learning to analyze content and behavioral signals, generating audience and contextual data without relying on cookies, device IDs, or other personal identifiers.

Its product suite includes Advanced Behavioral targeting for real-time, deterministic audience moments, Affinity Audiences for demographic and interest-based segmentation, and Deep Contextual analysis for content classification. These solutions are designed to help clients increase addressability, attract premium advertisers, and improve monetization in environments where traditional identifiers are limited or unavailable, such as podcasts.

NumberEight reports coverage of over 95% of podcast content across more than 200 countries and 28 languages. The company has partnered with Barometer to make its podcast-specific Affinity Audiences available through The Trade Desk demand-side platform, enabling advertisers to target segments such as sports fans, business leaders, and fitness enthusiasts. Clients cited in company materials include advertisers in automotive, retail, CPG, and entertainment sectors.

The company is led by co-founder and CEO Abhishek Sen, with a management team that includes a CTO, Commercial Director, and Machine Learning Lead. NumberEight positions itself within the privacy-first advertising space, emphasizing compliance with data privacy regulations while enabling audience targeting and curation at scale.
