Experience

Adamant Links

https://adamantlinks.com/
We can predict the customer's personality with almost pinpoint accuracy by analyzing user behavior, interests, and soft bio-metric measurements. The prediction algorithm currently uses the Big Five personality test (OCEAN). Based on the analysis of a user's behavior, we can predict the personality profile, biological gender, and age group in the current session. Clients using this service can label and store their clients' data according to their GDPR possibilities.

Persona to Personality
