Our customers

Our story

Assembly was founded in 2013 with the vision to revolutionise payments and help businesses harness opportunities presented by the digital age.

Since then we have been helping customers automate payment workflows that push the boundaries of what’s possible and reduce the complexity of running both classic and digital-native businesses.

Helping businesses compete and scale by managing payment complexity has always been a priority for Assembly and in February 2020 we joined forces with Standard Chartered to form a joint venture that will deliver the next generation payment solutions for businesses in Australia and beyond. 

We are now preparing to grow our presence across APAC, Europe the US and Africa in the next few years and to continue helping customers navigate the payments ecosystem.
