Overview

Signifyd provides an enterprise-grade cloud security platform engineered to protect online merchants from digital payment fraud and revenue loss. The system uses advanced machine learning models and big data analytics to automatically parse checkout transactions in real time. A core pillar of the platform is its financial guarantee model, which shifts chargeback liability entirely away from the merchant onto Signifyd for approved shipments. By removing administrative review tasks, it enables e-commerce brands, global retailers, and payment providers to safely maximize transaction approval velocities.

Founder story

Signifyd was founded in 2011 by Rajesh Ramanand and Michael Liberty in Palo Alto, California. Drawing on their extensive history as core risk specialists within PayPal's emerging market units, they saw firsthand how manual fraud screening stunted checkout conversions. To fix this financial friction, they engineered an automated system capable of backing its machine learning decisions with an absolute financial shield.
