# Quantdeck

Quantdeck is a London-based marketing analytics and data intelligence company that helps businesses decode complex customer journeys across fragmented digital touchpoints. They specialise in translating raw data into actionable insights that drive measurable improvements in marketing ROI and media efficiency.

The company serves mid-to-large enterprises across retail, hospitality, and e-commerce sectors—including recognised clients such as Asda Walmart, Interflora, and luxury hotel groups. Their core offering addresses a critical challenge facing modern marketers: understanding how customers interact across multiple devices and channels while optimising advertising spend in an increasingly competitive media landscape.

What distinguishes Quantdeck is their technical sophistication combined with practical implementation. Their proprietary data-cleansing and attribution systems employ Bayesian and Markov statistical analysis to accurately allocate credit across marketing channels, moving beyond simplistic last-click models. Their single-line-of-code implementation eliminates lengthy IT development cycles, whilst their machine learning infrastructure processes vast datasets to deliver individual-level predictions.

Rather than offering generic analytics dashboards, Quantdeck provides bespoke, customisable reporting tailored to specific business requirements and departmental needs. Their multi-device tracking capability creates a unified customer view across all platforms and locations, enabling businesses to calculate true customer lifetime value and redistribute budgets from underperforming to high-performing channels with greater accuracy than competitors.
