Customer Analytics

Turn CRM and transactional data into retention, growth, and measurable business decisions.

  • Customer value: quantify LTV/CLV and identify value drivers
  • Retention: predict churn and design targeted retention actions
  • Segmentation: build actionable segments for targeting, lifecycle management and personalisation
  • Growth: uncover cross-sell / upsell opportunities and next-best-action

Marketing Mix & Effectiveness

Measure what works, quantify incremental impact, and optimise spend across channels.

  • Contribution: quantify baseline vs incremental impact by channel and tactic
  • Efficiency: estimate ROI and response curves (diminishing returns, saturation, carryover)
  • Optimisation: run budget and mix scenarios to maximise outcomes under constraints
  • Validation: design measurement to verify impact beyond correlation (tests / causal checks)

Research & Insights

Translate research into decisions, strategy and actionable recommendations.

  • Understanding: identify needs, drivers, barriers and perceptions behind behaviour
  • Segmentation: define needs-based segments with clear implications for targeting and messaging
  • Evidence: quantify trade-offs and priorities (drivers, choice models, pricing preferences)
  • Activation: turn findings into decision-ready recommendations and workshop-friendly narratives
