OIF Ventures is led by founding partner David Shein, who built and sold Com Tech Communications for over A$1 billion, giving the firm direct experience creating a billion-dollar Australian tech business rather than just investing in one. The firm operates with a humility-driven approach where Shein positions himself as "the dumbest guy at the table," preferring to back founders by asking questions and learning from them rather than positioning itself as the smartest person in the room.
