CompatibL Tech Stack

Risk and limits platform for derivatives dealers and central banks

Software Development Princeton, NJ 201–500 employees Founded 2003 Privately Held

CompatibL builds mission-critical risk, limits, and regulatory capital software for institutional finance — four major derivatives dealers, 25+ central banks, and supranationals. The tech stack reveals a mature engineering operation: C++/C# core with Python, QuantLib, and heavy cloud infrastructure (Azure, Kubernetes, Snowflake, ClickHouse). Active migration from Azure (replacing in stack) and pivot toward cloud-native data architecture (Snowflake, Data Lake, Spark) suggests infrastructure modernization is the primary internal focus. Engineering-heavy hiring and narrow specialization (risk only, no adjacent products) indicate deep domain expertise over breadth.
