About Mathilde

Are you looking to accelerate your B2B acquisition, generate more qualified leads, or structure your marketing funnel? This is exactly where I come in.

With 10 years of experience in Digital Growth Marketing and 7 years in the MarTech/SaaS ecosystem, I support startups and scale-ups in implementing high-performing and measurable acquisition strategies. Notably, I contributed to SimilarWeb's IPO and Insider's funding round, where marketing accounted for 70% of closed commercial pipeline.

My areas of intervention include: marketing automation (acquisition workflows, nurturing, scoring), inbound & outbound lead generation, multi-channel paid campaigns (Google Ads, Meta, LinkedIn, TikTok), SEO/SEA strategy, and data analysis to identify priority growth levers.

I work on a project basis or on a retainer, for short or long-term assignments, primarily for B2B SaaS, tech, or scaling companies.

Let's discuss your project, I'll respond within the day.
