Why the name Arkadiko?

Arkadiko Partners is named after the Arkadiko bridge, a Mycenaean bridge near the modern road from Tiryns to Epidauros on the Peloponnese in Greece. Dating to the Greek Bronze Age, it is one of the oldest arch bridges still in existence and use.

We chose this name because of its ancient solidity, connecting past and present. It is a metaphor for our mission to provide a bridge to a purpose-led financial system that contributes to a sustainable world.
