About us

What we stand for

Normal photo 1513335613

Delivering the best possible healthcare to patients worldwide, requires an efficient research process that drives innovation in healthcare. Currently, 85% of resources spent on medical research do not contribute to patient health. At Castor we are creating user friendly technology that solves these issues. Founded by an MD PhD, we understand that researchers want technology to work for them, not against them.  

Our goal

We want to accelerate medical research by unlocking the potential of every researcher. Starting with an easy to use and affordable EDC we want to help researchers throughout the entire medical research process. Our goal is to ensure the world’s research data becomes reusable and machine readable, so that we can leverage the power of AI to help us solve the biggest healthcare challenges.

Our growth is accelerated by the fact that we have been awarded a €1.1M grant as part of the European Union Horizon 2020 SME (Small and Medium sized Enterprises) Instrument program. This allows us to expedite our growth plans and develop our products much faster than anticipated.

The media is starting to pick up on our story too:

Castor life

How we work

We work in a healthy, efficient (no overhead!), and challenging environment. We have daily body breaks, a lego table (see right) and frequent meditation sessions. Working with us also means having time for other important things in life. We love tech and are always finding new productivity hacks (in Slack, IFTT integrations, marketing automation, etc) to allow us to start the Friday drinks early 😀

“We click as a company. People have a lot of fun coming into the office.”

Our location

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. Our office is not down-town, but the metro there takes 15 minutes.

We will sponsor your highly skilled migrant visum which gives you benefits such as:

  • The 30% ruling, which makes 30% of your income tax-free.
  • No need to do the Dutch driver test exam, you can use your old license
  • Extremely fast processing (join us in two weeks)
  • Your partner can work here and doesn't need to follow civic integration courses
