The IV Ibero-American Forum on Public Procurement of Innovation (CPI) and Open Innovation will take place November 16-18 in Brazil (Rio de Janeiro) as a reference for open innovation in the public sphere to exchange experiences and connect the agents of the innovation ecosystem from the different countries. The focus of this edition will be to take advantage of the lessons learned from 10 years of CPI implementation in Spain, going through the life cycle of the CPI: from necessity to deployment, as well as the identification of future challenges and the need to generate public- public, public-private and private-private connections to allow faster progress.
