Saar Wilf

In 2018, he founded payments system Quahl (originally known as Initiative Q), backed by American economist Lawrence H. White and branded a "pyramid scheme with grandiose ideas" by the Financial Times due to the way it harvests users' personal data and promises thousands of dollars in value to those who sign up and invite five other people. Seven million users had signed up within a year.

By 2017, he invested in about 15 companies. His companies have included ClarityRay (acquired by Yahoo), Pointgrab, Deep Optics. and CallApp.

In 2017, Wilf founded Rootclaim, which uses probabilistic analysis to predict the likely solution to questions about controversial events such as chemical weapons attacks. For example, it attributes the 2013 Ghouta chemical attack in Syria to rebels and the downing of Malaysia Airlines Flight 17 to an accident.

His company Bzigo, founded in 2016, has developed a machine which scans a room for mosquitos and tells mobile phones where they are, describing itself as "an Iron Dome for mosquitos". In 2020, its machines were scheduled for delivery to customers in 2021, with customers encouraged to sign up by being offered large discounts for paying in advance of the technology being developed.
