Professional Focus

Voice of Customer Intelligence

  • Classify open text by sentiment and themes
  • Export Excel or BI-ready tables with charts for non-technical partners

Product Analytics

  • KPI design, funnels, retention cohorts, lightweight LTV
  • Clean executive readouts that drive a decision

Experimentation

  • Guardrails, lift estimates, and concise one-pagers
