Vivun Inc.

AI sales teammate for sellers

Vivun builds Hero, an AI sales teammate helping sellers win the moments that actually decide deals — before, during and after each conversation. Powered by a proprietary Sales Reasoning Model, Hero helps sellers arrive prepared, respond confidently, keep conversations focused and maintain momentum between interactions. That last capability matters most: deals are usually lost in the gaps between meetings rather than within them, when nothing happens and interest cools. The company is building technology that changes how people work, collaborate and succeed together.
