ActiveReaction is your EDC technology partner


How it all started

How it all started

ActiveReaction was founded in 2002 by two brothers: Peter and Marcel Vlietstra. They saw a gap in the online market research sector. With their in-house developed Online Survey Form Builder Software, ActiveReaction initially provided traditional market research companies with an easier, quicker and more cost-effective way to collect market research data: via smart online survey forms.

Today, ActiveReaction offers a wide range of software solutions to multiple market sectors, focussing on more complex data capture & data management processes, such as investigator-initiated clinical trials & clinical research (eCRFs, Clinical Trials Management Software), digital works council elections, video content optimising tests and multi-lingual market research projects.
