Clients have included the BBC and Channel 5, and the firm also runs a developer training programme. Nearly all of its delivery happens in the UK, so it competes on quality and communication rather than price.

The UK business marked 25 years in 2025 and has nearly 150 staff across London, Manchester and Edinburgh, led by UK CEO Angela Bishop since October 2024. UK clients include HSBC and NHS England.
