Techinnov happened a couple of weeks ago. Now in its tenth year, this cross-industrial trade fair has become an important component of the Île-de-France innovation ecosystem. Once a year in February, the upper floor of Orly airport thus turns into a marketplace for large industrial companies, suppliers, labs, consultants, startups and investors. Together they represent a big chunk of the local innovation ecosystem. They were there mostly to do business: 9000 scheduled meetings took place.
