Together they conceptualise their first custom algorithmic programme. James would move on to become a key executive for Grasshopper.

Our Future

For the past decade, Grasshopper has profitably evolved and innovated in a famously cutthroat industry.

We don't deterministically predict the future. Instead, the firm is focused on fostering a culture of curiosity and innovation, which allows us to quickly react to the market, wherever she decides to go.


As Grasshoppers, we're nimble, humble and poised to leap higher than ever before.
