A boutique agency
Sister is based in Amsterdam, the Netherlands. We work with national and international brands, and we can take a project from concept through to execution. Or we can help you with one of the steps along the way.
We collaborate with a strong, trusted network of senior creative entrepeneurs whose knowledge and experience span different disciplines. Each time we take on a project, we call on the Sisters best suited to telling your story. We’re flexible, dedicated, and prefer short lines of communication. Work with us and you won’t need to deal with multiple account managers or intermediaries before you can speak to your creative team. By keeping the direct line open, we can help you achieve your ambitions at a competitive price.
for charming brands
Sister was founded in 2007 by a team of women. As female creatives, we felt that more could be done to respond to the needs of women. We developed our philosophy of charm marketing based on the feminine values of humanity, warmth, and presence (being there for your consumer). We believe these values have the power to connect to people and create meaningful relationships. If your brand wants to make a positive impact and contribute to a better world — let’s talk!
Meet the Sisters
The name Sister says it all. We care. We connect. We speak our truth.
We encourage long-term relationships based on shared values. We love finding creative ways to communicate with different audiences. And we will never put our egos before your cause. We work for brands who share our values so that we can continue to do our work with enthusiasm and commitment.
Walks her talk with a creative and (pretty) sustainable
After more than two hectic decades working in TV and advertising, Valentine realised she needed a more conscious way of living. She changed her lifestyle to healthy, set her mind to meditation, her diet to vega, and started to teach yoga classes alongside her creative work. Ever curious and adaptive to the changing world, she’s ready to wield her creative experience to make a difference.
