With the mission “To raise global economic prosperity through programmable internet commerce,” Circle was founded on the belief that blockchains and digital currency will rewire the global economic system, creating a fundamentally more open, inclusive, efficient and integrated world economy.  We envision a global economy where people and businesses everywhere can more freely connect and transact with each other with new technologies for digital money. We believe such a system can raise prosperity for people and companies everywhere. Our mission is powered by the values we espouse and which we expect all Circlers to respect. We are Multistakeholder, serving the needs of our customers, our shareholders, our employees and families, our local communities and our world. Furthermore, we are also Mindful, Driven by Excellence, and High Integrity.

Engineering at Circle:

In 2020, Circle unveiled Circle APIs: a set of solutions and smarter technology to help businesses accept payments in a more global, scalable and efficient alternative to traditional banking rails (spoiler: we’re using USD Coin under the hood).

Over the next 12 months, we’re going to rapidly grow our API customer base and enable even more businesses to easily integrate and benefit from the breakthrough of programmable money on the internet.
