About this role

TreasurySpring is the product of an obsession with fixing the fundamental structural problems in money markets. Our fascination with the sector began painfully, during the Global Financial Crisis of 2008, where we had a front-row seat to watch the evaporation of liquidity in fixed income and the near collapse of the entire short-dated funding markets.

We have been on a mission to help deliver more sustainable solutions for the money markets ever since, and we launched TreasurySpring in 2018 to offer institutional clients a single gateway to the broadest range of the best risk-adjusted cash investment options. As a fast-growing London-based financial technology company, we deliver a unique solution to a global multi-trillion-dollar problem, delivered globally from our offices in London and New York.

Our regulated Fixed-Term Fund platform delivers new digital pipelines to connect cash-rich firms to institutional borrowers. Clients include large Private Equity funds, Asset Managers, listed Corporates, high-growth tech companies and many more.
