About Sébastien

I audit, I turn around, and I govern enterprise Salesforce programs, including those that have gone off track.

Independent Salesforce Consultant.

I take end-to-end responsibility for enterprise programs.

Including those that have gone off track.

Fourteen years in enterprise CRM.
The last decade on Salesforce, for European groups: Lacoste, L'Occitane, TotalEnergies, Sanofi.

At Cognizant, I co-piloted the growth of the Salesforce EMEA practice, from 5 to 200 consultants.
Then I went independent.

Where I intervene:

1. Program Takeover.
Implementation at a standstill, go-live slipping, integrator relationship broken. I find the cause and get the delivery back on track. A program brought back to full velocity in three months.

2. Org Audit.
An independent view of a Salesforce org that has grown without a framework.
With an actionable roadmap.

3. Multi-cloud Governance.
Keeping a large park consistent across Sales, Service, Marketing, and the data layer.

4. Training.
Salesforce admin and architecture. Concrete and practical, for your teams.

On Agentforce and Data Cloud: I drive program readiness and governance.
Specialists build.

I deliver the result, not the keyboard.
