TSY Capital

TSY Capital is unusually candid about its plumbing for a firm its age: low-latency trading systems written in Rust, the research layer built on Python and AWS, a clean two-tier split that signals a systems-engineering culture from the start.

Founded in Hong Kong in 2022, the firm uses machine learning to find and trade inefficiencies across global equity markets in pursuit of risk-adjusted returns. The wider toolkit runs to Java, PyTorch, TensorFlow, and CUDA, and its small team of developers and quantitative researchers works closely together, with some presence in mainland China.
