Voicebox, founded by Karan Gupta, lets shoppers scan a QR code or tap an NFC chip to record up to 20 seconds of spoken feedback, which is transcribed, sentiment-analyzed, and delivered to a company dashboard. The startup has deployed the system in airport terminals and at events such as Lena Dunham’s book launch, and it recently introduced a public “directory” where users can browse crowd-sourced voice reviews of businesses.
