Work that matters
What you work on reaches the top tables in Europe. At the Benelux Summit in Maastricht, we gave a live demo of the European Business Wallet to the three Benelux prime ministers: Rob Jetten, Bart De Wever and Luc Frieden.
We showed how the wallet saves entrepreneurs a great deal of paperwork when they do business across borders. The demo ran on existing eIDAS technology from Cleverbase, together with building blocks from the WE BUILD consortium. Rob Jetten's message: “The sooner, the better.”
Everyone safe online. That is what we work towards every day.
