Ons Team


Anne Pleun van Eijsden

Founder & Operations/Sales

For a long, long time I have been dreaming of starting my own company. To build something from the ground up. Something lasting and something contributing to the beauty in the world. With On The Rocks I’m realizing that dream. Entrepreneurship runs through my veins. I love to get to know other people, and learn about lives, ambitions and dreams. Make real, honest and open connections. I’m also mother to Lizzy (2) and spend time with my family.

Design & Brand

Not quite what you’d expect at first encounter, even more confusing during conversation, but eventually it all falls into place. That’s exactly how you’d feel when you meet me. As an English-wielding Asian with a potently Dutch moniker, I’m a bit of an odd duck but an interesting one nonetheless. At least, I’d like to think so! I’m essentially curious, and I look through a design lens that goes beyond aesthetics. I’d love to share and translate that to augmenting basic education someday, particularly for children in less favourable circumstances. Coz if knowledge is fundamental, then curiosity is a prerequisite. And we need more odd ducks.

Marketing & Communication

Working at On The Rocks is an amazing experience, a challenge as well but the good outweighs the bad heavily in this case. My background is in the hospitality management business, something totally different from this but a change was needed! And I’m happy I took this step. The fact that you know you are doing your best to change this world is a feeling I can’t describe, it feels good but surreal. From September I will be studying at The Hague university of applied science, the major I’m going to follow is European Studies. My interests outside of On The Rocks are music and basketball.
