Opendoor CEO Kaz Nejatian is turning around the company by using AI, proprietary data, and a focus on fast turnover instead of predicting home prices. They've expanded the buy box nationally, boosted acquisitions 5-6x YoY, shortened hold times dramatically, and launched a mortgage product in weeks—all while improving margins in a tough macro. Long-term vision: build a thick platform for buying, selling, mortgaging, and insuring homes to become the default.
