About
Yofi (acquired by NoFraud in October 2025) is an e-commerce fraud prevention platform focused specifically on return abuse and policy exploitation. The platform uses thousands of data signals — including device telemetry, customer clustering, return history, carrier data, and label tracking — to identify bad actors while preserving a seamless experience for legitimate customers. Yofi's consortium of over 1,600 merchants shares a continuously updated Bad Actor Database for proactive protection. The company detected $1.5B of return abuse in 2024 and integrates with Shopify, Klaviyo, and over 25 other platforms. Founded in 2021 by Jordan and Alex Shamir, Yofi was formerly known as BotNot and was headquartered in Bozeman, Montana.
