Bennett, a father of four and a modern Orthodox Jew, will be Israel's first prime minister who regularly wears a kippa, the skullcap worn by observant Jews. He lives in the upscale Tel Aviv suburb of Raanana, rather than the settlements he champions.
Bennett began life with his American-born parents in Haifa, then bounced with his family between North America and Israel, military service, law school, and the private sector. Throughout, he's curated a persona that's at once modern, religious, and nationalist.
After serving in the elite Sayeret Matkal commando unit, Bennett went to law school at Hebrew University. In 1999, he co-founded Cyota, an anti-fraud software company that was sold in 2005 to US-based RSA Security for 145 million.
Bennett has said the bitter experience of Israel's 2006 war against the Lebanese militant group Hezbollah drove him to politics. The month-long war ended inconclusively, and Israel's military and political leadership at the time was widely criticised as bungling the campaign.
Bennett represents the third generation of Israeli leaders, after the founders of the state and Netanyahu's generation, which came of age during the country's tense early years marked by repeated wars with Arab states.
He's Israel 3.0, Anshel Pfeffer, a columnist for Israel's left-leaning Haaretz newspaper, wrote in a recent profile of Bennett.
A Jewish nationalist but not really dogmatic. A bit religious, but certainly not devout. A military man who prefers the comforts of civilian urban life and a high-tech entrepreneur who isn't looking to make any more millions. A supporter of the Greater Land of Israel but not a settler. And he may well not be a lifelong politician either.
