Institute site licenses

Our site license model enables institutes to easily and rapidly deploy Castor EDC across their entire research institute. This ensures that every researcher within the institute has access to a powerful, secure and compliant solution. Rather than paying separately for each individual study, researchers have their own Billing Code, meaning institutes will not incur additional costs for each new study. Institutes can proactively engage with their researchers through a customized welcome email and stay in control through monthly usage reports.

Researchers can do fantastic things with Castor EDC! Based on their study protocol they can easily build and change their study structure. One particular researcher was so creative that he incorporated a large part of the protocol in the study structure.

Brechtje Hesseling

What I like about Castor is that I can create a user-friendly database that will also create a user-friendly output, i.e. that I can already prepare the data as much as possible to make data analysis easier.
