Kaz: We're Building Mortgage "Fully AI-Native from Day 1"
On Thursday, Kaz announced Opendoor is building a mortgage product with Lennar—designed from the ground up for AI, not retrofitted onto legacy systems.
The sixteen-word tweet carried more strategic weight than most earnings calls. "Fully AI-native from Day 1" isn't marketing language—it's a philosophical stake in the ground. Most mortgage technology was built in 2008, had machine learning bolted on in 2019, then got LLM capabilities in 2024. The result: Frankenstein software that works but groans under its own complexity.
Building AI-native means starting from the assumption that the machine is the underwriter, the processor, the closer. Humans become exception handlers. The economics change completely. For a company that's struggled to explain what it actually is—home buyer? marketplace? fintech in disguise?—this tweet suggests an answer: Opendoor is building the operating system for the transaction itself.
The Lennar partnership matters. Working with the nation's second-largest homebuilder means this isn't an experiment on the margins—it's Opendoor positioning itself at the center of new construction, where mortgage and transaction can be reimagined without existing infrastructure constraints.
