About Cox
Cox started in 2021 when two ex-quant developers got tired of watching their firms deploy bloated, over-engineered platforms that took minutes to boot and gigabytes of RAM to idle. They quit on the same Friday, rented a co-working desk in Austin, and spent six months building a trade execution CLI that fit in a 4 MB binary.
That CLI became the seed of everything Cox ships today. Word spread through prop-trading Slack channels and GitHub stars, and within a year a handful of small funds were running Cox tools in production. We took on zero outside capital and grew entirely through revenue, which kept us honest about what to build and what to skip.
Today Cox is a 35-person company with a single office in Austin and a remote engineering team across North America. We still ship every tool as a single statically linked binary with no runtime dependencies. Our clients range from two-person crypto desks to mid-size futures shops, and they all share the same philosophy: if it does not make you faster, throw it away.
Our Mission
To prove that the best trading technology is the one with the least code standing between a signal and a fill.
Our Values
Simplicity
Every feature we add has to justify its weight. If a capability cannot be explained in one sentence, it is too complicated. We delete more code than we write and consider a shrinking binary a sign of progress.
Speed
We measure boot time in milliseconds and latency in microseconds. Our build pipeline rejects any commit that regresses a benchmark by more than two percent, because speed is a promise we make to every client.
Autonomy
Cox is bootstrapped and intends to stay that way. No board seats, no growth-at-all-costs mandates. We answer to our clients and our craft, and that independence lets us say no to work that would dilute the product.
