Jesse Xu (CTO, Podqi) shares the framework that made his team pivot from patents to trademarks in under 4 months — if you can't validate your own AI's output, you're building in the wrong space.
Jesse Xu (CTO, Podqi) breaks down the 95/5 enforcement split — automate 95% of takedowns, investigate 5% for seven-figure legal settlements — and why clearing fakes grows baseline revenue 1-2%.
Jesse Xu (CTO, Podqi) explains the structural conflict of interest that lets fake products thrive on Amazon, Walmart, and Meta — and why platforms have no legal mandate to stop it.
