Company Description
Sift is a digital trust and safety company that develops an AI-based fraud decisioning platform. The company provides solutions for fraud detection, payment review automation, risk assessment, and dispute management to over 700 global brands in sectors including fintech, retail, and travel. Its platform processes data from a network of over one trillion annual events to help businesses manage risk. For example, Sift’s platform enabled the ticketing company Atom Tickets to reduce fraud-related chargebacks by 40% and decrease manual review time by 60%.

The company's recent activities indicate a focus on industry research and collaboration. Sift released its 2025 Fraud Industry Benchmarking Resource (FIBR), which analyzes fraud trends across different sectors. The company has also engaged with the broader industry by participating in events such as Payments MAGnified and ICE Barcelona, and by collaborating with organizations like the Merchant Risk Council on sessions exploring AI's role in fraud prediction. Sift's Q4 2025 Digital Trust Index also highlighted the financial and reputational risks associated with customer payment disputes and chargebacks.
