100-word summary
Simple AI just landed $14 million from First Harmonic, Y Combinator, and others to build voice AI agents that actually close deals. The platform ingests entire product catalogs and personalizes sales calls in real-time with sub-850ms latency—fast enough to feel human. Early results? These AI agents convert and upsell 30% better than trained live reps across categories from steak to home insurance. Co-founders Catheryn Li and Zach Kamran built the entire voice stack in-house. If AI can genuinely outsell human reps at scale, consumer brands may soon route their highest-value calls to bots, not people—reshaping both sales floors and customer expectations.
