On June 6, CCIA hosted a conference on the online platform ecosystem in Brussels. After a keynote delivered by DG CNECT’s Werner Stengg we had an expert panel discussion on the right regulatory framework towards online platforms. That panel was followed by a panel composed exclusively of online sellers and app developers – i.e. important business users of many online platforms. Our event was the first where the recently proposed Regulation on platform-to-business (P2B) relations was discussed.
