Client Success Stories
We've been helping organisations to achieve their goals since 2009. Here are some of our latest and greatest projects.
Working closely with doctors and other health professionals, we developed a new digital service for SXT. The platform lets patients discreetly notify their partners about a potential infection, and helps clinics to meet their KPIs.
We came on board to rescue the project. Not only have we built a website that will scale with the organisation, but also developed digital services that moved key transactions online.
Through in-depth research, we rebuilt the service. The improvements met stringent government standards and made it easier for thousands of organisations to apply for the awards.
In three months, we built an API that links Swiftkey with individual social media and email accounts. Each user now experiences a completely personalised service.
In three months, we rebuilt the complex tool to help users find the information they need easily. We continue to support it, and it now delivers over 2,300,000 page views a month, meeting the government digital standards.
Following extensive research, we developed a system that analyses data, frees up time for volunteers and helps clients access food without delays.
