As Partner at Big Pi, a venture capital firm investing in Greece, I support ambitious innovation. I enjoy new business ideas, optimistic entrepreneurs, critical thinking, leading-edge research and realistic targets. I am one of the pioneers of the private equity industry in Greece, beginning in 1995. I have been on the board of dozens of companies, in industries ranging from health clubs to bioengineering; including CEO positions in grape packaging and in business consulting. My experience includes new business and start-ups; acquisitions and divestments; governance; operations (logistics, costing and MIS, key account development); fund raising and fund structuring.Since 2010 I have been researching and commenting on economic and social issues, especially on the Greek crisis. My book "The Invisible Rift: Institutions and Behaviors in the Greek Economy" (in Greek) came out in 2013. I have a monthly op-ed column in Kathimerini, and I (used to) blog at aristosd.Wordpress.com
