“I had the chance to do several Learning Expeditions prepared by David. Their objective was simple: to understand and immerse oneself in a limited time with the world’s best innovation ecosystems, from the USA to China. Simple to say, but not easy to organize! But thanks to David’s multiple talents, it was each time a successful, unique and unforgettable experience. The relevance of the sites, companies and institutions we visited, the quality of the people we were able to meet, were each time an eye-opener. I simply loved it!! ”
