Who we are

We are a private equity firm focusing on investing in Greek companies that have the potential to grow and become better: better places for their employees, generating above average value for their shareholders, and contributing
to the country’s economic growth while protecting the environment.
We do this by teaming up with creative entrepreneurs and strong management teams to grow, improve, and transform these companies, working day by day, action by action, from the bottom up.

Our Values & Philosophy


We always strive to be the most responsible investor and owner of companies within the territory we operate in.
Our two most important assets are our reputation and our people.
We all work hard to keep each of us excited and proud of what we do: building up better, more valuable companies that measurably help their immediate environment, always observing the laws and our written or oral agreements.
This is the surest way to protect the other half of our assets, our reputation.


Deca Investments focuses on companies in which a combination of their management quality, sector dynamics, and fundamentals indicate that the expected risk-adjusted return will be attractive. These are companies with a proven track record, strong export potential or import substitution capability, and the potential to grow profitably. Deca Investments actively supports its portfolio companies by adding value, promoting good governance, and improving operational efficiency and acting responsibly within the social environment they operate.

Investments made for Diorama I include Adam Pack, Atlas Tapes, Axel Accessories, Damavand, ΕΖΑ, InternetQ, Lariplast, Minerva, PharOS and Viva Wallet.
