Clear Street

Clear Street is a financial technology firm working on the brokerage ecosystem. Its engineers build on a technical stack that includes cloud-native infrastructure, an API-based architecture, AI-enhanced systems and horizontally scalable design. The work spans real-time data and risk management and multi-asset clearing and custody systems, problems where latency, correctness and scale are all first-order constraints.

The company's core product is a unified, cloud-native, end-to-end capital markets platform intended to give clients real-time infrastructure to help minimise risk and facilitate growth, replacing the legacy systems used across capital markets. Alongside it sits a completely cloud-native clearing and custody system that supports multi-asset clearing with real-time data and risk management, with information held in a single system rather than spread across disconnected books.

Clear Street operates in capital markets, brokerage, financial services and institutional investing. Its stated orientation is technology-driven, built for today's complex, global markets and participants, with an emphasis on speed, transparency and scale and a modernisation mindset focused on retiring legacy systems.
