About Jonix
Jonix was founded in 2019 by a team of engineers and quantitative traders who saw a widening gap between the speed of global markets and the technology available to navigate them. What started as a skunkworks project inside a London prop-trading desk quickly grew into an independent technology company serving clients across three continents.
In the years since, we have scaled from a five-person garage operation to a 120-strong engineering organization with offices in London, New York, and Singapore. Our platform now processes over 4 million messages per second and supports more than 60 exchange connections worldwide.
We remain founder-led and privately held, which means every decision we make is driven by a single priority: building technology that performs when it matters most. We reinvest heavily in R&D because we believe the firms that win tomorrow are the ones whose infrastructure never blinks today.
Our Mission
To eliminate the technology gap between ambition and execution for every firm that trades global markets.
Our Values
Innovation
We treat every microsecond as an opportunity. Our engineering culture rewards bold experimentation and relentless iteration, because standing still in capital markets means falling behind.
Reliability
Markets never sleep, and neither does our infrastructure. We engineer for five-nines uptime and design every component to degrade gracefully, so our clients can trade with confidence around the clock.
Performance
Speed is not a feature—it is the product. From kernel-bypass networking to custom memory allocators, we obsess over every layer of the stack to deliver deterministic, sub-microsecond latency.
