What we do

Caplin's mission is to provide our customers with the best financial trading systems in the world. We aim to do this by delivering not only the best technology but by focusing on who this technology is meant to help: the people who use it every day.

Caplin believes that good design and user experience isn't just for discerning consumers, but for everyone, from day traders to corporate treasurers, and from sales dealers to system administrators.

Finance is a complex sector, but that doesn't mean it has to be complicated. Using the latest technology allows us to quickly and effectively deliver responsive, real time applications that connect with users and drive high levels of engagement. We strive to make complex systems simple and create solutions that are a joy to work with.
