Public budgets, procurement, or subscription revenue?
Platforms
Search, stores, marketplaces and payments — where most people meet the stack, and where least of it is European.
Five questions we ask of every layer
02 design
Who sets the architecture, and in the open?
03 build
Which vendors, which jurisdictions, which licences?
04 operate
Who holds the keys and answers the pager?
05 maintain
Who pays for it in year ten, when it is boring?
