Message from our CEO

Christer Nilsson:

"Today we offer a full suite of data collection software services"

We started our journey 20 years ago with a request to build an online CRF service for one of the world’s largest pharma companies, back then we were an IT operations provider for the pharma industry. This was the starting point of providing software for collection of data in clinical trials. Today we offer a full suite of data collection software services, and our IT operation is performed by our, very certified, sister company Complior.

We strive to keep things simple and customizable for the users and very secure in the backend. The data collection landscape is shifting rapidly. ePRO with gamification to increase participant compliance is a common requirement and automatic data collection from participants by using all types of devices is growing rapidly. The pandemic moved trials to a decentralized approach with video visits and remote participant monitoring.

The landscape is also shifting on the Internet. It is a tall order to keep services secure from the online antagonists. Last year we have seen an increase of, unfortunately, successful ransom ware attacks aimed at our competitors. We have a doctrine of how to segment each client and trial on dedicated servers, firewalls, web application firewalls and load balancers. All operated by Complior who is ISO 27001 and PCI DSS certified. PCI DSS is one of the world’s toughest certification for information security with annual audits.
