Sift

What Sift does

Sift (Sift Science, Inc.) is a privately held, San Francisco-headquartered fraud-prevention platform founded in 2011 that uses machine learning models trained on more than 1 trillion annual events to score risk in real time for digital businesses. Its platform unifies Payment Protection, Account Defense, Dispute Management, and abuse-prevention workflows around a shared view of user behavior from account creation through post-transaction, serving 700+ enterprise and mid-market customers across digital commerce, fintech, internet and software, travel, food delivery, and iGaming. The company's core technology rests on a Global Data Network that produces consortium models (ThreatClusters), cross-dimensional identity signals (Identity Trust XD), generative-AI-assisted account-takeover review (ActivityIQ), and a public Sift Score API for developers building internal risk models; the company holds 40+ patents and reports 13+ years of continuous model tuning.

Sift monetizes primarily through annual, quote-based enterprise subscriptions priced on transaction volume and features, supplemented by Professional Services and API consumption. Go-to-market combines enterprise field sales, a three-tier Partner Program (Authorized Resellers, Technology Partners, Service Providers), self-serve API distribution for developers, and a Sifters Community plus Trust & Safety University for practitioner engagement. The company has executed two acquisitions (Chargeback in May 2021 and Keyless in November 2021) to extend dispute-management and biometric-identity capabilities, and has been recognized as a Leader in the Forrester Wave for Digital Fraud Management (2023) and the QKS Group SPARK Matrix for eCommerce Fraud Prevention (2025), while holding #1 rankings across G2 fraud-prevention categories in eight consecutive 2024–2026 reports. In May 2026 co-founder Austin Spiegel was promoted to CEO alongside a new San Francisco office and a ~$67M funding round from undisclosed investors, with the company stating revenue has tripled year-over-year since 2022.
