Vivun positions Hero as an AI sales teammate for presales and solution-engineering teams: it joins calls, pulls the pre-call brief, surfaces technical and competitive answers live, then writes the CRM update and follow-ups back automatically, framed as ready to use without a rep configuring or maintaining anything. Distribution has leaned on plugging into where sales teams already work, including partner and agent-tool marketplaces. Conversation touching the brand has included analyst commentary on how AI sales tools price per-agent access, using Vivun alongside other AI-agent vendors as a reference point. It carries a quieter footprint so far relative to the broader selling-tools conversation.

Business Profile
Vivun was founded in 2018 as a presales platform before repositioning around Hero, an AI sales teammate built on structured domain knowledge and reasoning rather than generation alone. The company has raised $131M from investors including Menlo Ventures, Salesforce Ventures, Tiger Global, Unusual Ventures, Atlassian Ventures, and Accel, and operates independently with roughly 80 employees. Its recent public emphasis has shifted from presales tooling toward positioning Hero as a ready-to-use AI agent for the sales call itself, extending the company's original focus on solution engineers into the broader selling motion.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
Hero, Vivun's AI sales teammate, now ships as an approved connector in Anthropic's marketplace, positioned as usable on day one without a rep building or configuring anything: it pulls the pre-call brief, assists live on calls, and writes updates back to the CRM afterward. No public API documentation is on file yet for building custom integrations against it.
