about the founder

Kostis Tselenis - managing partner SIO

Kostis founded the Swiss Impact Office with the aim of advancing sustainable and impact-driven investments. With over two decades of experience in investment banking and investment management, he has been involved in a range of investments in innovative companies and funds, focusing on long-term positive financial and societal outcomes. He has served on the boards of forward-thinking organisations, contributing to efforts that bridge finance and sustainability.

Kostis’ commitment to impact is rooted in his family background. Coming from a family of entrepreneurs who pioneered one of Greece’s first sustainable and ethical cosmetics ventures in the 1990s, he grew up with a close connection to values of integrity, nature protection, and social responsibility. This second-generation perspective gives him a deep understanding of legacy, stewardship, and the importance of preserving values while innovating for the future. His family’s business was among the those companies in Greece of consistently operating with full compliance and transparency.

Today, Kostis carries forward this ethos in his professional work. He values collaboration, working closely with his international network of fellow investors, experts, and sustainability leaders and regularly participates in global discussions, sharing insights from his experience.
