WHAT WE STAND FOR

Delivering the best possible healthcare to patients worldwide requires an efficient research process that drives innovation in healthcare. Currently, 85% of time and money spent on medical research does not contribute to patient health.

Founded by an MD PhD, we understand that researchers want technology to work for them, not against them. At Castor we are creating user friendly technology that helps researchers capture high quality, standardized data, that they can share in a trusted environment.   

Making the world’s research data reusable and machine readable allows us to leverage the power of Artificial Intelligence to help us solve the biggest healthcare challenges.

We start our day with a meditation session (we even made it one of our team goals). We promote frequent body breaks and creative sessions at the lego table. Derk is not only our CEO and professional motivator, but also our sports coach in our (voluntary 😉) weekly outdoor training sessions.  

When you start working at Castor, you have the power to make a difference. Good arguments and data outdo hierarchy. We want you to excel in your role and life. To support this, we provide you a yearly budget for personal development.  

Working with us also means having time for other important things in life. We encourage you to work smart so that you can enjoy after-work hours. We love tech and are always finding new productivity hacks to allow us to start the Friday drinks early 😃.

Our team

What does it take to be a Castorian?

We have a diverse team with more than 10 nationalities. We are all unique in our own ways, below you find the things that combine Castorians: 

Passionate about making a difference - Being aligned behind our purpose makes us a better team and energizes us.

A fighter's mentality - Working in a fast growing scale-up isn’t always easy, Castorians can handle the rapid changes and abundant information coming in.

Enjoying life and having fun - We engage in healthy and/or fun activities like ping pong, the bake-off, obstacle runs and Friday drinks, but also make sure we spend enough time away from work. We believe in a healthy work life balance.

Respectful - There is power in a workforce that’s not homogeneous, therefore we support a team with many different types of people and cultures. 

Team players - A group of individuals will not achieve anything worth mentioning 50 years from now. A great team will.

The wonderful city of Amsterdam


Yes, we're biased, but Amsterdam is a great city to work and live in! Small village feel, but lots of stuff going on and plenty to see. Canals, museums, great parties, parks and the rest of Europe is only a plane ride away from European hub Schiphol Airport. Take a look at the Amsterdam Expat Centers top 10 reasons to love Amsterdam

We will sponsor your highly skilled migrant visum, which allows you to enjoy the '30% ruling' that gives you a major tax-break. Check the IN Amsterdam site for more information.
