Vivun builds domain reasoning models that enable intelligent agents to operate with structured knowledge, transparent logic, and real-world context. We don't chase the moment. We shape the architecture beneath it.
A research-led AI company with a disciplined point of view on how intelligence should be built, governed, and deployed in enterprise systems.
We build AI that reasons within defined domains — not general-purpose models that infer broadly, but structured intelligence that applies constrained, inspectable logic to real enterprise problems.
Revenue systems are knowledge systems. We architect the layer of structured reasoning that enables intelligent agents to operate inside the workflows where deals are won and lost.
Every model Vivun builds is inspectable. We believe AI governance begins at the architecture level — not as an audit feature bolted on after the fact, but as a first principle of how we build.
Vivun's research and architecture powers Hero — the AI Sales Teammate built for live selling. Vivun is the intelligence. Hero is where it meets the seller.
Three layers of structured intelligence — each designed to be inspectable, durable, and deployable inside enterprise-grade systems.
Structured representations of how a domain actually works. Not scraped summaries — purpose-built knowledge models that encode the logic, relationships, and constraints of enterprise revenue systems. These models tell agents what is true, what matters, and what the rules are.
Domain models are the foundation of inspectable AI. Without them, agents operate on statistical patterns. With them, they operate on structured understanding.
Logic that applies domain knowledge to real-world context. Vivun's reasoning engines don't generalize — they apply the right model to the right problem with the right constraints. The output is a structured decision, not a probability distribution.
This is what separates automation from intelligence. Automation follows rules. Reasoning applies judgment — transparently and repeatably.
Agents that act with structured intent. Vivun agents are purpose-built for defined contexts — not general-purpose assistants asked to figure it out. They know their domain. They know when to act. They know what constitutes a good outcome — and why.
Hero is the first Vivun agent deployed at scale. It operates in live selling: before, during, and after the moments that decide deals.
We publish what we learn. Vivun's research defines how AI should be built for enterprise domains — not to promote a product, but to advance the standard.
Five principles that govern every model, every agent, and every system Vivun ships. Non-negotiable. Present in the architecture, not just the documentation.
Vivun's architecture powers one product. Built for live selling. Trusted by enterprise revenue teams.
Hero is the AI Sales Teammate built on Vivun's domain reasoning models. It operates inside live selling — preparing sellers before meetings, supporting them during conversations, and preserving momentum after every call. Vivun is the intelligence. Hero is where it meets the seller.
Where Vivun's structured reasoning becomes something a seller can feel inside a live conversation.
