Sift Science was founded on June 1, 2011 from the Y Combinator incubator program, the world’s most powerful start-up incubator and breeding ground for many tech companies. They publicly launched their product on March 19, 2013. Jason Tan, the Chief Executive Officer (CEO) and co-founder of Sift Science, is a software engineer with an illustrious career prior to establishing his company. He interned at Boeing, worked as a software design engineer at Zillow, worked as an engineer at Optify, and served as the Chief Technical Officer (CTO) at BuzzLabs before conceiving the idea of an online fraud protection scheme.

At the Y Combinator incubator program, he met his fellow co-founder Brandon Ballinger and worked on a product that would help businesses grow while eliminating the threat of frauds. They built a machine learning fraud detection solution where the algorithm of the software will learn what the potential threats were, entirely on its own. It “sifts” the fake and dangerous users from the real ones based on the data.
