About Our Data & ML Team

Data & AI powers our growth and innovation. We build enterprise platforms to create actionable insight enabling colleagues to make effective decisions and create proactive, automated, hyper-personalised experiences for our customers.

We have a growing data and AI team in the UK and Netherlands.
