MCD Systems was founded in 2017 by technologist Lyle McCalmont to focus on building digital products that are practical, impactful and genuinely valuable to the people who use them. With a background in development and a strong interest in how technology can drive meaningful change, the business was created to offer a more thoughtful, outcomes-focused approach to digital transformation.
Since then, MCD has grown into a trusted partner for organisations across the UK. The mission remains the same. To create digital solutions that are clear, effective and built with care, combining technical expertise with real business understanding to deliver tangible results.
