Description

If you're reading this, you're probably managing HR on top of everything else.

And you feel like things are starting to get complicated.

HR Director for a multi-site, multi-country group for 3 years, during hypergrowth — I saw firsthand what breaks when left unattended, and what can be fixed in 6 months if done right.

Today, I do it on an outsourced basis for SME leaders with 40-200 employees across multiple sites who don't want to hire a full-time HR Director and don't have time to wait.

Specifically, over the last 3 years:

–52% turnover · 0 litigation despite restructuring · €120-180k in risks avoided · €2M+ in payroll managed at +2.7% vs inflation · multi-country · 100% social compliance.

3 areas of intervention:

→ Legal and social security (multi-site payroll, labor law, employee representative bodies, avoiding litigation)

→ Organizational structuring (processes, harmonization between sites, post-acquisition integration)

→ Manager and executive support (skills development, managing sensitive situations)

Sectors: retail · e-commerce · restaurant · multi-site services · logistics · healthcare.

Proprietary method Risk Compass™ (4S — Specify · Structure · Solve · Scenario).

Format: 1-4 days/week · available quickly · 40-200 employee SMEs in IDF (Paris region) prioritized + remote for other regions.
