Who we are
A piece of the moon, a complete dinosaur skeleton, the Pope's hat, the world's smallest book - at Catawiki, we come across exceptional objects such as these every day. The special object you’ve been searching for, or a new and unexpected interest you never thought you’d have: the more you look, the more you’ll find. And at Catawiki, there’s always more to the story. Every day sellers submit thousands of objects to sell on Catawiki. Our 240+ in-house experts review and select only the best to auction.
Our mission is to connect passionate enthusiasts with the objects that tell their stories. As Europe’s fastest growing online auction platform, we help over 10 million people discover new treasures every month. This means we are continually growing and always on the lookout for new talent!
Born and raised in The Netherlands, we started in 2008 and have since grown to over 750 Catawikians, working across 7 international offices, while maintaining our start-up mentality every step of the way. In December 2020 we received a new €150m investment round led by Permira and are excited to be growing our team and business further across the world.
Catawiki’s purpose is to enable people to discover and obtain special objects that help them fulfill their passions. In doing so, we add some color & make the world a more interesting place.
Our Data Story
With ten-thousands of active items on auction every day, hundred-thousands of bids, millions of users, and billions of events, the Catawiki platform generates vast amounts of data. We collect this data centrally, using it to generate business insights, as well as powering machine learning models that enhance our user experience, optimize our workflows, and keep our platform safe. We believe in creating flexible models that can be applied to a variety of use cases, and in experimentation and iteration to hit the ground running and continually improve the tools we build.
The Data Team, which covers the full data spectrum of Machine Learning, Analysis and Data Engineering, has a clear a mission within Catawiki:
Why: We believe that by using data in a smart way, we can build the best Catawiki possible. We want to have impact and see opportunities everywhere.
How: We are builders, thinkers and talkers. We collaborate closely with every department to create value for our customers. We think big and hold ourselves to high standards, because our work really matters for the future of the company.
What: As a result we create business value by delivering scalable, robust models and actionable insights and predictions. We help the company to find opportunities and understand success, and we empower everyone to use data to be successful.
