FingerprintJS empowers developers to solve online fraud.

Basic Information

Founded in 2019 by Dan Pinto and Valentin Vasilyev, FingerprintJS helps prevent fraud, spam, and account takeovers with its browser fingerprinting as a service technology framework. The startup’s JavaScript technology combines hundreds of signals inside any browser to generate a unique identifier that can be used to detect unusual behavior patterns such as devices entering stolen credit cards or the same browser using multiple IP addresses. By working closely with the open source community, FingerprintJS claims that it has unearthed a variety of fraud use cases that their technology can solve, including protecting login pages from unauthorized users, stopping fake account signups, reducing credit card fraud, and preventing SaaS account sharing. In February 2021, the company raised $8 million in Series A funding led by Nexus Venture Partners. See more
