THE BARCELONA ACCIÓ CONFERENCE at the end of January was full to capacity with entrepreneurs and investors: lively speakers, elevator pitches from companies ranging from specialty Pharma to IT, and full-on networking. Among the thousand or so attendees was a Boston entrepreneur, originally from Mumbai, who had moved to Barcelona with his family, because of the dynamic entrepreneurial environment. Barcelona has given birth to a tremendously dynamic and imaginative culture of young companies, and is no longer just a hot vacation destination.
