Case Study: KEF achieves a 32% ROAS increase and full cross-channel revenue transparency with Windsor.ai

KEF measures the impact of their global media activities onto online and offline revenue

KEF, the British loudspeaker manufacturer, faced the challenge of expanding from B2B into direct B2C sales while measuring the impact of global media across complex, multi-channel customer journeys. With transactions split across online stores, e‑commerce partners and brick-and-mortar retail, KEF needed to centralize diverse marketing and revenue data and understand how upper‑funnel brand activity translated into online and offline conversions. They worked with Windsor.ai and its Attribution Insights platform to address this.

Windsor.ai integrated all of KEF’s revenue and marketing data into Attribution Insights, applied a data‑driven attribution algorithm, and matched attributed performance to platform costs to show clear cross‑channel ROI. As a result, KEF gained full transparency into spend and performance, increased overall ROAS by 32% across channels, and can now quantify how online advertising drives both offline and e‑commerce partner conversions.
