Yigal Landau is a businessman and the CEO of Ratio Oil Exploration. In 1992, he co-founded Ratio along with his father and others to focus on oil exploration in Israel. While early efforts focused on onshore exploration, Ratio shifted to exploring the Levant Basin offshore in deeper waters. This risky move proved successful when the Leviathan gas field was discovered, estimated to contain 22 trillion cubic feet of natural gas. Landau believes Israel needs energy independence and private sector exploration to prevent dependence on other countries for fossil fuels and bring economic benefits.
