Sift — Valuation, Funding & Investors

Sift runs a fraud prevention platform that scores over 1 trillion events a year across more than 34,000 sites and apps, serving over 700 brands including DoorDash, Yelp, and Poshmark. Its machine-learning models flag payment fraud, account takeover, and account abuse in real time while showing analysts the signals behind each decision instead of a black-box score.

The company holds more than 40 patents covering its fraud-decisioning technology. Separately, under the Sift Stack brand, the same name is used by a distinct observability platform for mission-critical hardware, ingesting telemetry for aerospace, defense, and autonomy programs.
