About Gwenn

👋 Hello, I'm Gwenn and I've been working in digital acquisition for 6 years, from launching initial campaigns to scaling budgets into 6 figures. Today, I'm putting this experience to work for your projects.

🎯 My added value: an analytical profile that relies on data to concretely improve your performance. I dig into the numbers, identify what drives results, and continuously optimize your campaigns.

🔧 What I do concretely:
- Digital Advertising: Creation and daily management of your campaigns on Meta, Google, TikTok, or LinkedIn Ads to optimize your cost per acquisition.
- Audit & Strategy: Technical analysis of your accounts and definition of an immediate action plan to improve your results.
- Tracking & Data: Installation and configuration of your Pixels, Conversion APIs, and GTM to ensure the reliability of your data.
- Reporting: Clear dashboards to manage your investments in real-time.
- Training: Interventions in schools or coaching for your teams to build their acquisition skills.

💼 I adapt to all profiles. I currently work with:
- An agency - managing several hundred thousand euros monthly on Google Ads.
- An established start-up in its market.
- An entrepreneur launching their business with a controlled starting budget.

Whether you're looking to start properly or scale up, I integrate as immediate operational support.

✅ With me, you gain: a data-driven, ROI-oriented approach, true transparency (quick responses, strategic advice included), and measurable results.

📩 Audit of your accounts, occasional support, or long-term partnership? Contact me, I'll respond quickly.
