Back to original languageAbout Sébastien
For over a decade, I have led the social media strategy and paid acquisition for a leading global cybersecurity brand. Meta, TikTok, LinkedIn, X, YouTube: I have designed, deployed, and optimized campaigns that combine performance and brand image.
My playground covers the entire spectrum:
Paid Social Ads: account structuring, targeting, A/B testing, budget optimization, and ROI-oriented reporting.
Organic Social Media: editorial line, calendar, community management, competitive intelligence, content creation.
Influence & UGC: management of influencer campaigns and creator content production, from brief to analysis.
I actively integrate generative AI tools into my workflows — visual creation, copywriting, data analysis.
What I bring concretely:
A strategic vision fueled by 12 years in a demanding B2C and B2B environment.
A link between Organic and Paid Social.
Meticulous execution, inherited from a large structure, with the agility of a freelancer.
Genuine curiosity for new formats, platforms, and technologies
