Formerly a journalist in the defense & security sector and then a marketing manager in the theme park sector, Harold has a rich international background. It was in 2017 that he fully embarked on the blockchain and web3 sector, first as a consultant and then head of communications at, a French startup that raised $2M in ICO in early 2018 for the development of an AI capable of creating new market indicators for traders on crypto markets. From Paris, station F and the first European blockchain project incubator Chain Accelerator, he gained a lot of experience in a short period of time before coming back to Belgium to create Be Blockchain SRL in late 2019, a blockchain consulting and development company. We quickly became a key player in Belgium and the logical next step was the launch of WalChain, the official business network of the Walloon region that brings together the government, universities, clusters and private players.
