About ComplyAdvantage

Since launching in 2014, ComplyAdvantage has been on a mission to neutralize the risk of money laundering, terrorist financing, corruption, and other financial crime on a global scale. In that time, we have raised over $100m in funding, have four global hubs located in New York, London, Singapore and Cluj-Napoca and are backed by Ontario Teachers', Index Ventures, Balderton Capital and Goldman Sachs.

We aim to grow to over 350 employees in the next 12 months, as we continue to fight the good fight against financial crime and help make compliance less painful for our client base of over 500 enterprises across 75 different countries. We're leveraging game-changing tech to help us on our mission as the financial industry’s leading source of AI-driven financial crime risk data and detection technology.

We are building cutting-edge solutions that help reveal the truth for a safer world and stop money ending up in the hands of terrorists.
