About the client
Kent Engineering & Foundry (KEF) is a British audio equipment manufacturer founded in 1961. Known for its innovation and audio fidelity, KEF gained prominence through collaborations with the BBC, producing iconic speakers like the LS3/5A.
Today, KEF sells its premium loudspeakers, subwoofers, and headphones globally, across both digital and retail channels.
As the company expanded from B2B into B2C sales, understanding how marketing spend translated into revenue—especially across online, partner, and offline touchpoints—became a strategic priority.
Challenges
As KEF grew its direct-to-consumer presence, its marketing and analytics teams encountered several operational challenges:
- Fragmented data across platforms: Spend data lived in Google Ads, Facebook Ads, and affiliate platforms, while revenue was split across KEF.com, retail partners, and brick-and-mortar stores.
- Disconnected customer journeys: A typical buyer journey might begin with a Facebook ad, include several touchpoints, and end in an offline store, making attribution complex and imprecise.
- Lack of centralized insights: Global, regional, and local campaigns were managed in separate environments with siloed reporting. This made it difficult to evaluate performance or optimize budget allocation in real-time.
KEF needed a data integration and attribution solution that could consolidate its full marketing and revenue picture, quantify the effectiveness of upper-funnel activity, and connect media investments to actual business outcomes.
Solutions
To solve these challenges, KEF adopted Windsor.ai as its centralized data integration and attribution platform due to the following features:
| Windsor.ai capability | Benefit to KEF |

| Cost-to-revenue mapping in real-time | Clear ROI visibility across all regions, platforms, and channels |

Results
