Proof Authentication
Proof Authentication is a Boston-based technology company that builds anti-counterfeiting and brand-protection solutions for large consumer brands. Its patented approach pairs a non-duplicatable printed mark with a custom smartphone app, letting consumers verify a product's authenticity in seconds while giving brands real-time data to enforce against counterfeits. Formed in 2021 to acquire the DSS Digital division of Document Security Systems, the company is led by CEO Dan McKinnon, former Head of Global Brand Protection at New Balance, and serves Fortune 500 companies.
