Hear from our clients
Differenz have provided London Sport excellent web development services across three products. We have been delighted with all areas of their work; expertise, technical knowledge and account management. We have asked Fazil and his team to take on the rebuild of an existing product, the ongoing development of another and build another from scratch – on all they have exceeded expectations.
The team have worked in a few projects for me: some from scratch and some fixing the work of other developers. They’ve always been responsive, professional and done a great job. I continue to use them for all of my website and app development tasks.
Differenz have been providing ongoing app and web development services to us for the last two years. They have great expertise and we have always found their work of the highest quality, even when handling extremely complex requirements. They also provide great customer service, with our account manager always on hand to talk through requirements and issues. Highly recommended!
