Whispli is a comprehensive platform, but is an expensive option given what it offers - FaceUp is 80% cheaper with a very similar suite of features. Unlike FaceUp, it places a limit of 20 on the number of members you can have and is only available in 60 languages, compared to FaceUp’s 113.
FaceUp also provides the highest level of data protection and anonymity - it is GDPR compliant, ISO 27001 certified, and offers E2EE encryption and 2FA. FaceUp is trusted by 3,900 organizations of all sizes across the world.
