Balloon

Balloon is a behavioral-science-based collaboration platform that helps teams surface ideas, feedback and insights without groupthink. Through its 'Flights' feature, teams share and evaluate input anonymously and asynchronously, removing the cognitive biases, hierarchy and group dynamics that silence quieter voices in meetings. Founded by public-health researcher Amanda Greenberg and engineer Noah Bornstein, Balloon counts companies like Google, Amazon, Capital One and MasterClass among its users and reports cutting meeting time by roughly 70% while surfacing information that has never been heard inside an organization.
