Sift

Sift is a digital trust and safety platform that uses global machine learning to prevent payment fraud, account takeover and spam. Founded in 2011, it is based in San Francisco and says it analyzes over one trillion events a year, learning from a consortium of 34,000+ sites and apps.

Fraud products The list includes Payment Protection, Account Defense against ATO, Content Integrity and a real-time ML risk score. Pricing follows enterprise SaaS by volume of checks, and the company describes its reach as global.

Dispute management A separate tool uses the telemetry of Sift's anti-fraud network to build evidence for payment disputes: automated evidence packets, network-wide historical transaction proof for CE 3.0, pre-dispute alerts and win-rate analytics. It draws on a customer's cross-merchant history of successful purchases to show that a transaction was legitimate.

Customers Target sectors are e-commerce, fintech, crypto, marketplaces, travel, gaming, digital goods and food delivery. Merchants should ask how consortium data is used and which dispute types are supported.
