Unit21
Unit21 is a Fraud Prevention & Risk Signals company founded in 2018 and based in San Francisco, United States. It has raised $92M in total funding, most recently a Series C in 2023.
Founded in 2018 by Trisha Kothari and Clarence Chio, Unit21 sells no-code risk and compliance infrastructure that lets non-technical fraud and AML teams build detection models, run transaction monitoring, and manage case workflows and suspicious activity reports without engineering support. A $34M Series B led by Tiger Global in 2021 valued the San Francisco company at $300M, and it followed with a $45M Series C, taking total funding to roughly $92M. The company has since repositioned around AI-driven risk infrastructure.
Unit21 put fraud and AML detection logic directly in the hands of risk operators, decoupling compliance monitoring from engineering roadmaps at banks and fintechs.
