Our take
Persona enables businesses to verify customer identities, fostering trust in online interactions and aiding in age verification, fraud prevention and account recovery. It offers a comprehensive suite of automated identity verification components with worldwide coverage that can be configured, branded and themed to create custom-tailored flows for any use case.
Businesses and governmental organizations can access Persona’s platform via an API, which supports various documents from government-issued IDs to biometrics, ensuring customers are who they claim to be. Persona’s platform also collects passive signals such as a user’s device, location and behavioural patterns to provide a more holistic risk profile, beneficial in financial and insurance contexts.
An impressive partnership with MDT saw Persona enable credit unions to adjust their identity verification flows in real-time, strengthening fraud prevention. The company continues to attract funding which supports the scaling of its offerings and reach. In fact, in 2025, it reached a $2 billion valuation, which showcases the success it has had.
