We are the Builders of ArgosTech and we are building the future of retail

We build technologies that customers and colleagues love and other builders respect. But we’re building more than technologies, we’re also building ourselves.

The future of retail technology won’t come from a single effort or invention, but rather from ArgosTech teams empowered to build that future. That’s why we invest in people and teams, not projects.

Our Engineering teams build new tech in greenfield status across several digital channels such as our Website (1B yearly visits), In Store Digital Tablets (12M+ monthly users), Mobile Apps (6M+ downloads) and 900 Retail Stores. We have been ranked the 2nd largest digital retailer in the UK and have just been awarded with 'Tech Retailer of The Year 2017.'
