About Phronesis



n. Practical understanding; wisdom, prudence; sound judgement

Phronesis sits at the intersection of mobile networks and fraud intelligence. Our extensive knowledge and experience allows us to craft practical solutions that others do not see. With this, our clients can feel confident in the decisions they make when validating customers - minimising fraud and assuring their brand integrity.

We understand the challenges of customer validation, and the scale of risk that it represents to businesses. Because of this we act as creative partners with our clients to resolve problems from simple to complex.



James and the Phronesis team have a long history of working in the telecoms space, they have been heavily involved in shaping the global A2P SMS space and moving the industry to one of high standards and compliance.


Whilst on this journey the team began to see the increasing value in the use of unique data that is held inside mobile and telecom operators, this data has the potential to address many of the operational and security challenges facing enterprises when transacting with their customers in a mobile lead environment. Early on we understood most of these enterprises are applying web solutions to a mobile journey, which is based on different technology and consumer behaviour, so their frustrations are borne out of solutions not fit for purpose and a lack of available alternatives.


The question for the Phronesis team was how to provide this unique customer data under a controlled and trusted framework in which the customer has full knowledge and consent of how the data is being used, but in an easy to understand and use format that an enterprise can leverage to make critical business decision. Thus Phronesis was born.


We believe that by combining the knowledge of the Phronesis team in relation to operator data, the high-quality data obtained directly from partnerships with leading mobile network operators and an understanding of the challenges facing today’s enterprise we can create solutions that will make mobile simple, safe and secure once again.
