|---|---|---|---|---|---|---|
| Research Phase and Lessons from Failed Mortgage Startups | 3 | 5 | 1 | 1 | Laks explains why UX-focused mortgage startups failed due to high CAC and the rigid Fannie Mae/Freddie Mac securitization box.

| Target Customer Profiles and Automated Qualification Process | 2 | 3 | 1 | 1 | Laks outlines their rapid qualification pipeline using Plaid and explains how ZeroDown arms buyers with all-cash offers to close within weeks in competitive markets.
