What Quadrature does

Quadrature Capital Limited is a private, London-headquartered systematic trading firm founded in 2010 by programmers Greg Skinner and Suneil Setiya. The company builds fully automated trading systems that execute across all liquid, electronically tradeable asset classes using only its own proprietary capital — it does not manage external client funds, offer investment advisory services, or sell software or data products. The technology stack is centered on C++, Python, and Rust, with a proprietary grid scheduling system that coordinates thousands of servers for research, simulation, and live trading; the majority of compute capacity is hosted in Norway using 100% renewable hydroelectric power. Modular components are shared across trading strategies to maximize per-strategy impact, and all trading is fully automated.

The firm operates from three offices: its London headquarters at the Leadenhall Building, a Singapore office opened in 2023 to cover APAC markets, and a New York office opened in Soho in September 2024. It holds FCA authorization under firm reference 692613 and maintains regulatory compliance across all three jurisdictions, with a global employee base of 101–250. Quadrature transitioned to being entirely internally funded with proprietary capital, eliminating external investor redemption risk and enabling long-horizon strategy development.

In 2019 the founders established the Quadrature Climate Foundation (QCF), an independent charitable foundation under the Charity Commission for England and Wales, funded by allocation of trading profits. QCF focuses on human security, poverty and inequality, and climate resilience, primarily in the UK, Europe, and Sub-Saharan Africa, and has committed more than $1.7 billion to over 180 partner organizations since inception. The Quadrature Group has paid in excess of £2.5 billion in UK corporation tax to date, indicating sustained large-scale profitability over the firm's 14-year history.

Core offering

Quadrature is a systematic, proprietary trading firm that builds and deploys fully automated trading systems to generate returns on its own proprietary capital across all liquid, electronically tradeable asset classes. The firm does not offer investment management, advisory, brokerage or other external financial services; its entire commercial activity is internalised around its own trading book, supported by quantitative research and a proprietary grid-scheduled compute infrastructure.

Product overview

Quadrature operates as a single, unified proprietary trading business rather than a platform with separate products or modules. Their core offering consists of automated trading systems that leverage cutting-edge technology and quantitative research. The systems are built on modular, shared components designed to trade across all liquid electronically tradeable asset classes. The technology stack primarily uses C++, Python, and Rust, with all trading being entirely automated. The company does not offer discrete product modules, add-ons, or separate service offerings—its business model centers on proprietary capital trading rather than selling software or platforms to external customers.
