Why is Castor so affordable?

Very often when we are approached by potential customers (most of whom end up choosing Castor), we get asked the question as to how we are able to make Castor so affordable compared to other EDCs which are usually much more expensive. The answer is 3-fold:

  • Company mission: our goal is to make reliable and secure data capture available to all researchers, which starts by making Castor affordable
  • Efficiency: we leverage technology to become always more efficient so we can build Castor while staying a small and efficient team of experts
  • Financial Support: we were awarded a €1.1M grant from the European Commission to further build great features into Castor while keeping its pricing low

Offer: small studies are free

Small studies, as indicated in the price calculator are free for non-profit organizations. There is a maximum of 5 free studies per academic department or non-academic institute.

Non-commercial and commercial

We differentiate between non-commercial (non-profit) and commercial studies. If you are a commercial company (e.g. CRO) or your study Sponsor is a commercial company (e.g. a Pharmaceutical company or a Medical Device company) our commercial pricing applies. The study Sponsor is the organization that has initiated the study and is designated as such in your study protocol.
