Hero vs. Grain

Vivun's AI Sales Teammate, Hero, works alongside sellers before, during, and after customer conversations, helping them prepare with the right context, respond confidently in real time, and preserve momentum through immediate follow-through. Every deal comes down to a handful of critical moments. A question you didn't anticipate. A conversation that shifts direction. A follow-up that can't wait. Vivun shows up inside those moments, not after them, so sellers can perform when the outcome is still undecided.
