Felipe Sinisterra and Dave Wang cash big checks telling Wall Street bankers what’s missing from their AI plans.

Wang, 31, showed how Gemini, the AI model developed by Alphabet Inc.’s Google, could be used to analyze founders’ pitch videos. He demonstrated how a web application incorporating behavioral analysis methods used by the FBI could help compare a transcript with visual cues such as body language and facial expressions to spot potential red flags.
