Vivun
Vivun is an AI-powered presales platform that helps enterprise B2B companies scale their sales engineering teams through structured intelligence. Founded in 2019 by two married couples with 25+ years of combined presales experience, Vivun builds AI agents that reason through expert knowledge rather than simply generating language - grounding every deal recommendation, demo, and forecast in the structured expertise of elite practitioners. With $131M raised and customers like Snowflake, Okta, Zoom, and CrowdStrike, Vivun has become the operating system for technical sales.
