Before becoming successful gaming entrepreneurs, Shiff and Chameides worked in military intelligence for the Israel Defense Forces (IDF). The pair’s first business was Product Madness, a maker of casino games hosted on Facebook, in 2012. Five years later they teamed up with Turkish-born Akin Babayigit, a former Facebook executive who started his career at the consultancy McKinsey. The trio’s mobile gaming developer Tripledot Studios specialises in card and word-related games, such as solitaire, blackjack and sudoku. Their biggest hit so far has been Woodoku, a wooden block game not unlike Tetris. A 2022 fundraising put a value of £1.1bn on the London-based firm.
