Who are we?

The best way to show who we are is with a little video!

You can follow us as a team on Facebook and Twitter! And you can follow individual team members on Twitter as well, like Hans, who loves enterpreneurship, Peet, who supports many crowdfunding projects, or Anne, who can't stop talking about robots and artificial intelligence.

Apart from work, if you're into martial arts, drop Bart a message. Peet likes everything that involves audio and Alex is into 3D animations.

Plan my journey

Plan your return trip with Rotterdam Central departure times. Count two minutes walking through the Groothandelsgebouw.


Crownstone is originally developed by DoBots, has as seed investor Almende Investments, is part of the Rockstart accelerator, and is a company since 2016!

We recommend that you scroll through the website and the blog to know what the role of our products can be in a business-to-business context. Indoor localisation has wide applicability apart from use at home, including (informal) care, flexible places at work, and preventive maintenance.

We have a very transparent manner of operation. You can find a lot of information about us online, such as the Kickstarter where we raised over 70.000 euros for the Crownstones, our blog, where we give you a lot of insight into our projects, and our github repositories.

You can find here also a press kit with high-resolution pictures.


The Crownstone team is extremely well versed in a wide variety of skills. We have all been to Dutch or international universities and like challenges above anything else!
