About Sébastien

When customer data becomes a C-level topic, I step in.

Three acquisitions, three CRMs, one ERP, and nobody knows exactly how many customers the group has. This is where I come in. I design the architecture that consolidates the chaos and lead the teams that build it.

Yes, I lead CRM programs when it's the right decision. But I start by analyzing the situation and processes, not the tool. Vendor choices come after the business objective is clear, not before.

THE TYPE OF SITUATION I STEP INTO:
At Intescia, we went from 3 entities, 3 CRMs, 1 ERP, and a manual invoicing process to a single CRM integrated with the ERP to automate the Lead2Cash process. Production pilot delivered in 9 months. Harmonization of customer databases: 40k phantom accounts reconciled into 8k billable entities. Direct report to COO, roadmap presented to investors.

CRM architecture audit for Engie's investment office, COMEX deliverable. Salesforce Org supporting investment decisions of several million euros.

THE RECURRING PATTERN: fragmented systems, unusable data, scaling pressure, a board that needs visibility for yesterday.

MY DIFFERENCE: Focus on impact - my recommendations adapt to operational maturity, not to vendor licensing models.

I WORK BEST WITH:
→ CxOs who want operational visibility before launching a CRM program
→ Boards that need group customer insights to activate acquisition synergies from day 1

Sébastien was involved in leading the phase 1 of a strategic Lead to Cash project. He was instrumental in defining the architecture, coordinating with integrators, negotiating with Salesforce, coaching the internal team, and facilitating stakeholder engagement. Always precise, reliable, and willing, Sébastien integrated perfectly into our structure. I hope we will work together again!
