What RSMB does

RSMB Solutions is a UK-based data science and audience measurement firm headquartered in London, founded in 1987 (per firmographics) and operating with 11–50 employees. The company provides audience measurement, methodology validation, and data enrichment services to media owners and platforms, media agencies, measurement vendors, and advertisers. Its client base includes the UK's principal joint industry committees (Barb, RAJAR, IPA) as well as broadcasters and brands (Sky, Samsung).

The company's flagship product is RSMB Fusion, a proprietary data fusion platform that enables clients to combine, model, and enrich datasets in-house. RSMB Fusion is distributed as a Native App on the Snowflake Marketplace (since March 2025) and on the Microsoft Azure Marketplace (since May 2025), and underpins operational products such as Barb's Data Hub, Barb Ads Hub, and successive phases of Barb's API. Supporting service lines — Measurement Solutions, Validation Services, and Data Enrichment — address cross-platform viewership measurement, independent methodology auditing, and dataset enhancement for advertising strategy and ROI work.

RSMB operates a B2B services model with custom enterprise pricing, multi-year contracts, and quote-based sales. GTM is consultative field sales segmented by client type, supplemented by content marketing via blog, LinkedIn presence, and industry event participation. Revenue is not publicly disclosed; no funding rounds, acquisitions, or institutional investors are recorded in available data, and the company appears to be independently held. Operating geographies extend beyond the UK to Germany, Italy, the Netherlands, and Sweden.
