About Us

D4 is a software studio based in Birmingham, UK.

We work from a beautiful Grade II listed building in Birmingham's Jewellery Quarter, come and say hello!

As well as delivering software projects and offering consultancy in user experience (UX), technical design and performance optimisation: we also have our own in-house products;

Prodlytic - analytics for product managers

QueryTree - a visual data reporting tool

SQLizer - convert any file into a MySQL database

Our products are used by 1,000s of people each day, all over the world.

Our ‘secret sauce’ is the carefully refined process we’ve developed over 20 years experience in building software for the web.

We constantly iterate and improve this process which covers the end-to-end project lifecycle from sales to support.

Don’t think ‘red tape’, it’s more like ‘paved roads’ that help us to get things done more quickly and to a higher quality.

We've been working on the web for over 20 years, we are D4.
