Jane Street Capital is a world leader in high-frequency trading (HFT), responsible for over 10% of all equity trading in North America, with an annual trading volume exceeding $17,000 billion.
At Jane Street, trust, reliability, and the ability to model complex relationships are paramount. To support these requirements, the company built its entire infrastructure in OCaml, a language known for its expressiveness and strong type safety. In the fast-moving world of financial markets, however, speed is just as critical as correctness, trading algorithms must react to market changes in fractions of a second.
In the ultra-competitive world of high-frequency trading, every microsecond counts. Jane Street needed to enhance the performance of their OCaml-based trading systems while maintaining the safety and reliability that OCaml provides. The challenge was to optimize the compiler itself to generate faster, more efficient code without compromising correctness.
Jane Street selected Titagone for our unmatched expertise in OCaml compiler internals and optimization. As experts in programming languages with deep academic roots, our team combines theoretical knowledge with practical experience in high-performance compiler development. Our ability to understand and enhance the most complex parts of the OCaml toolchain, while maintaining the correctness guarantees that financial systems demand, made us the ideal partner for this mission-critical work.
Since 2012, Titagone has partnered with Jane Street to enhance the OCaml compiler. Our work focused on adding advanced optimization passes, enabling programs generated by the compiler to run faster and more efficiently.
The results exceeded expectations. The optimizations provided a significant performance boost, enabling Jane Street's trading systems to process market data and execute trades more quickly than ever before. Encouraged by this success, Jane Street made the strategic decision to develop their own custom OCaml compiler, with Titagone continuing to work alongside their in-house teams.
Beyond raw performance, this partnership demonstrates the value of combining specialized language expertise with deep domain knowledge. Together, Jane Street and Titagone have created a robust, high-speed infrastructure that scales to the demands of global financial markets while maintaining the safety and reliability essential to their operations.
Let's discuss how we can optimize your critical systems for maximum performance and reliability.
