About Us
Our name is no coincidence
Reken means "count" or "calculate" in Dutch. We pronounce Reken the same as the English word "reckon", which also gives us our second meaning: we founded the company to help society deal with the reckoning we face with AI and cybersecurity.
Built on years of using AI to protect Google and the world's top banks against cybercrime
Our co-founders Shuman Ghosemajumder and Rich Griffiths led the creation of products at Shape Security that used AI to defend the world's largest banks, airlines, and federal agencies against sophisticated bots and cybercrime. Shuman previously founded Google's Trust & Safety product group and helped launch Gmail. At Google, he helped build some of the largest machine learning systems to stop cybercriminals who were simulating human behavior to create fraud, protecting over 1B users and advertisers.
Today at Reken, we have assembled an elite team with world-class backgrounds in artificial intelligence, security, computer science, design, communication, and game theory, to rethink how we can approach persistent problems in security and build An Internet Safe for Humans.
