About
Signifyd is a fraud prevention and commerce protection company founded in 2011 by Rajesh Ramanand and Michael Liberty, headquartered in San Jose, California. The company's core product is a machine-learning-powered fraud platform that evaluates every order placed on an e-commerce site in real time, assigning a confidence score and a financial guarantee: if Signifyd approves an order and it turns out to be fraudulent, Signifyd reimburses the chargeback — shifting the liability from the retailer to Signifyd. This chargeback guarantee model fundamentally changes the economics of fraud prevention, allowing merchants to approve more orders with confidence rather than declining borderline transactions out of caution.
