About Marie-Helene

Too many priorities. Not enough decisions.

I help organizations unlock their product and Customer Experience (CX) decisions — fast.

I align Product Strategy, Product Discovery, and Customer Experience (CX) to transform complex situations into concrete, actionable decisions.

Decisions rarely slow down because of the teams.
They slow down due to a lack of alignment between Product Strategy, Customer Experience (CX), and delivery.


🎯 Typical cases
– too many priorities, no clear decisions
– unstable or constantly questioned roadmap
– fragmented or inconsistent customer journeys
– misaligned Product, Customer Experience (CX), and business teams
👉 Result: wasted time, diluted efforts, postponed decisions

🎯 Example — AXA Banque
Facing fragmented customer journeys and unclear Customer Experience (CX):
→ structuring Product Discovery
→ product prioritization
→ alignment of Product Strategy, Customer Experience (CX), and business teams

Result: clarified priorities, accelerated decisions, strengthened Customer Experience (CX), smoother delivery.

🎯 Role
Quickly unblock the situation and get teams moving again.
In a few days:
– clarification of a Product Strategy issue
– Product / Customer Experience (CX) / business team alignment
– structuring Product Discovery
– acceleration of decisions and consistency of customer journeys

⚡ Express diagnostic (30–45 min)
→ Rapid identification of blocking points
→ Highlighting of Product / Customer Experience (CX) misalignments
→ Immediately actionable recommendations

🎯 Objective: unblock a situation in a very short time, without long-term commitment.

🎯 Positioning
I primarily intervene on high-stakes issues:
product decision-making, journey performance, Customer Experience (CX) transformation.
