If anything having to have to develop and maintain an entire ecosystem probably slowed them down more than anything.</text><parent_chain><item><author>hardwaregeek</author><text>I&amp;#x27;ve always been curious whether someone will succeed in using the same development strategy as Jane Street, namely using a non-C++ language as their primary language. I suspect OCaml may have been a very good choice back in the early 2000&amp;#x27;s simply because C++ was a much different language and there weren&amp;#x27;t many options for other languages. Building up an ecosystem was not a bad plan because most languages did not have much of an ecosystem anyways. Nowadays ecosystems are a lot more developed. But on the flip side, that could mean you could stand to use a language like Rust that has an ecosystem and interoperability with C++. I know Tsuru Capital uses Rust but I&amp;#x27;m not familiar with any other firms.&lt;p&gt;It also could be that Jane Street succeeded regardless or even despite OCaml. At the end of the day OCaml isn&amp;#x27;t going to ensure that your trading strategies work. It&amp;#x27;s not going to suddenly create alpha. But I do suspect they&amp;#x27;ve gotten serious hiring and marketing returns by using OCaml. And benefited the OCaml ecosystem as a byproduct, which is a pretty solid side-effect, even if side effects are not very functional :D</text></item></parent_chain></comment><story><title>How to Build an Exchange (2017)</title><url>https://www.janestreet.com/tech-talks/building-an-exchange/</url></story>
