Compliant and principled delivery

Our app made history, as the first certified mobile medical device in the UK. It was informed by our 55-year track record creating value-add solutions in complex and highly regulated environments like financial services, healthcare, and government.


Collaboration with diverse partners

Innovations beyond traditional organisation and industry borders was key to the success of this project. We enabled a diverse ecosystem of government, science, and big tech. This data-led co-innovation played an essential role in creating a powerful mobile medical device at scale.

The robustness and scalability of our Amazon-powered cloud infrastructure was vital in accommodating the needs of the app’s 22+ million users.

Collaboration with the National Centre for Cyber Security, and their surprise security testing, ensured the app's safety and user protection.

With the help of our innovation partners Google and Apple, we collaborated on ways to enhance the precision and speed of contact tracing APIs to better serve users.

We collaborated with the Alan Turing Institute to transform anonymised test and trace data into valuable, actionable knowledge.


Data-driven decision making

We helped turn anonymised app data into real-time insight on virus patterns and policy impact with a health digital twin to support the COVID-19 response.
