Blis

Blis operates an advertising technology and data platform built around location intelligence. It ingests and aggregates anonymised location, telco and point-of-interest signals, applies geospatial and AI models, and exposes the resulting audiences and insights through its own planning and buying tools, a self-serve demand-side interface, and programmatic data feeds. This creates value for agencies, brands and programmatic buyers by enabling more accurate, geography-based targeting and post-campaign measurement (e.g., footfall, store visits) without relying on individual identity graphs.

The company’s business model combines enterprise software access with media and data enablement. It provides self-serve access to its platform for agencies and trading desks, offers managed-service campaign execution for brands that want full-service planning and buying, and supplies verified location data into external DSPs and programmatic environments via a private exchange. The data and platform are positioned as privacy-compliant infrastructure that complements existing programmatic workflows rather than functioning as a consumer-facing product.

Blis is a UK-based location intelligence and advertising technology company focused on privacy-first audience targeting and measurement. It provides a platform that aggregates and analyses anonymised location, telco and point-of-interest data to build geographic-based audiences, plan campaigns and measure outcomes such as store visits and footfall across digital channels, including mobile and digital out-of-home.

The company monetises this capability through a mix of self-serve programmatic tools, data access and managed advertising services. Its primary customers are media agencies, trading desks, demand-side platforms and brand marketers who use Blis for location-based audience creation, buying and campaign measurement, as well as programmatic platforms that consume its verified location datasets via a private exchange. Blis became a wholly owned subsidiary of T‑Mobile US in 2025.
