More than 100 people from 24 countries have brought the best way to accept card payments to 15 countries so far, but we won’t stop there. SumUp is headquartered in Berlin, with major offices also in London, Sofia and São Paulo. We recently launched a brand new contactless device, which makes paying by card easier than ever before.
SumUp is interesting for you as an engineer in part because we cover so many platforms: we have physical hardware (made right here in Berlin), our own proprietary payment processing platform, mobile apps on iOS and Android, SDKs and APIs supporting third-party integration, and of course (the main star, in our humble opinion) a merchant-facing web app.
