Willemijn Dickhoff
Athlete Content Partnerships · Influencer & UGC · Trilingual Specialist
I spent years managing complex pan-European influencer and UGC programmes for global brands, including a full-scale programme for one of the largest clear aligner brands in the world. Marketing Lioness is what I built to do that work at the standard it deserves, and to take on the athlete content gap that no European agency is properly filling.
Pan-European influencer and UGC management. Trilingual content across EN, FR, and NL, B2C and B2B, three markets simultaneously. Editorial content production for luxury travel and lifestyle brands: video, photo, interviews, and podcasts. My track record is in the most regulated, demanding environments. That rigour transfers to everything we produce.
Based in Béziers. Working across EU, US, and Africa.

Athlete Representation · Platform Builds · AoS & TGC Founder
I founded Ambassadors of Sport because pro athletes are the most badly advised professionals I have ever met. Short careers. Weak commercial representation. No off-pitch financial support. No infrastructure for life after the game. AoS exists to change that.
AoS represents athletes across rugby, motorsport, golf, sailing, equestrian, hockey, and basketball. 15% commission. No cut on playing salary. Off-pitch concierge support through The Gatekeepers Club: visa, family, property, tax, and post-career planning, included for every athlete on the roster.
Also the technical architecture behind everything Marketing Lioness builds, from creator submission portals to direct booking platforms to AI-assisted content workflows.
