About Ingrid

Senior Product Manager — Growth B2C | Conversion · Retention · Funnel · Product AI

Do you have traffic but insufficient conversion? Onboarding that doesn’t activate enough? Declining retention?

I help B2C products generate sustainable growth by acting on three key levers: convert better, activate faster, retain longer.

For 13 years, I have worked on web, mobile, and e-commerce with a structured approach: product analytics, data diagnostics, ROI prioritization (RICE), experimentation (A/B testing), and business impact piloting.

Measurable Results

  • +27% active users (470K → 600K) - Poulpeo
  • +21% iOS conversion (+€12K/month) - Poulpeo
  • Critical customer journey redesign - Fortuneo
  • E-commerce became the 1st sales channel - Beaumanoir
  • Activation & retention optimization - Hellowork
  • +5 NPS points - Poulpeo

What I do

  • Funnel & conversion: journey audit, A/B testing, web/mobile CRO
  • Activation & onboarding: time-to-value reduction, product analytics
  • Retention & engagement: cohorts, churn, retention strategy
  • Roadmap & prioritization: backlog, RICE, product-business-tech alignment
