Media buying alone is dead. Performance is driven by creative strategy and in-depth analysis of *real* business data (COS & CAC NC, healthy LTV/CAC ratio...)
If you agree with this👇
Former Agency Account Manager, I support high-growth DNVBs and Ecom businesses.
The 3 pillars of my support:
1/ Creative Strategy (primarily via Motion)
2/ Solid Tracking
3/ Management for real profitability (COS/MER, CAC New Client, %NC).
Ecom Results and Experiences
- **Toutou Petcare**: +84% revenue vs. previous year with stable COS. My mission led to a 25% decrease in CAC, a 20% increase in AOV, and the establishment of an iterative testing methodology.
- **Bloon**: Supported the scaling of this French DNVB through a creative strategy focused on product benefits (ergonomics and design).
- **Maison Hela & By Hela, Performe**: Managed acquisition with a focus on the wellness, cosmetic, and food supplement sectors.
Creative Strategy Expertise
- **Analysis**: Proficient in Motion to make numbers speak (Hook Rate, Hold Rate...).
- **Briefing your internal teams (if applicable)**: Writing UGC scripts and precise editing briefs for your creative teams, based on psychological mechanics and real data.
- **Testing**: Setting up a proper creative testing structure (adapted for Andromeda) to isolate winners and scale with predictability.
Management and Data
- **Reporting**: Setting up Looker Studio dashboards to manage by COS/MER (included).
- **Tracking**: Installation and audit of GTM & Meta conversion API to ensure reliable data flow.
Levers
- **Meta**: Primary & essential lever.
- **TikTok**: Second phase, but relevant via UGC.
- **Google**: Capturing intentional demand.
