Frequently asked questions
What is Vivun Hero?
Hero is Vivun's AI teammate for sales, positioned as on-call expertise that helps sellers win bigger deals faster. The vendor shows it listening into calls, researching stakeholders, updating CRM records and drafting follow-ups, with answers surfaced on screen in real time and a whisper mode for in-call prompts.
How much does Vivun Hero cost?
Vivun does not publish pricing on its website. Hero is offered to individuals and enterprises with a free trial, and enterprise pricing is handled through the vendor's contact channel, so budget discussions require a quote.
Which CRM and other tools does Hero connect to?
Vivun's product material shows the Hero desktop app connected to calendar, CRM and MCP, but no named CRM vendor or published integration list appears on the pages reviewed. Confirm target systems with Vivun during evaluation.
What security and compliance certifications does Vivun hold?
The Vivun trust centre is published but does not name specific certifications such as SOC 2, ISO 27001, HIPAA or FedRAMP on the pages reviewed. Buyers with strict requirements should request documentation directly.
How is Hero different from a general-purpose AI assistant?
Vivun argues generic LLMs lack persistent world models and must rebuild reasoning on every prompt. Its method extracts expert mental models, formalizes them as ontologies and knowledge graphs, then orchestrates reasoning over that structure, a discipline the vendor says it applied first in music, finance and enterprise sales.
What does deployment involve?
Hero is delivered as a desktop app with a free trial for individuals, which points to a light-touch start. Vivun publishes no implementation fees, timeline or IT prerequisites, so enterprise rollout effort should be scoped directly with the vendor.
