Hero® was built for the seller who has to show up, answer the question, and keep the deal moving. Everything else follows from that.
Most sales AI records calls, scores performance, writes emails, and automates sequences. None of that helps when a buyer asks a question you didn't expect and you have three seconds to answer.
Hero was built for that moment: the live conversation where credibility is tested and the deal either moves forward or quietly stalls.

Chatbots answer when asked. Assistants do what they're told. Hero does something different. It understands your deals, your products, your buyers, and your competitive landscape. It shows up before, during, and after every conversation. And it gets better the more you work together.
General-purpose AI can sound right. Hero is built to be right. It reasons from your actual deals, your actual products, and your actual sales process. It doesn't guess at what might be true. It works from what it knows about your business.
Call intelligence tools tell you what happened. Hero is there while it's happening. It listens to live conversations and surfaces the right answer in the moment, not in a summary you read later.
Some platforms deploy dozens of task-specific agents that each need to be configured and maintained. Hero is a single teammate powered by one model. Update your messaging or launch a new product, and Hero knows about it in every conversation. No cascading updates. No maintenance overhead.
Hero is powered by a Sales Reasoning Model. That's different from the general-purpose AI behind most tools. Here's what it means in practice.
Most AI tools search for similar-sounding text and hand it back. Hero understands how the pieces fit together. It knows the difference between a champion and a decision-maker, why a pricing objection in month one means something different in month three, and how a competitor's recent acquisition changes the conversation. Connections, not just keywords.
Hero doesn't just give you an answer. It tells you where that answer came from: which call, which email, which data point. You can see the reasoning behind every recommendation. That's how you learn to trust it.
Hero carries context across every interaction. What a stakeholder said in the first discovery call still informs the strategy in the final negotiation. It tracks commitments, flags risks when things change, and keeps the full picture current without you having to remind it.
Hero doesn't wait for you to ask. If risk escalates in a deal, it flags it. If a competitor comes up for the second time across calls, it logs it. If a follow-up is due, it drafts it. This is the difference between a tool that waits and a teammate that thinks ahead.
You train Hero through conversation, not a settings panel. Give it your products, positioning, competitive landscape, and sales process. It learns like a sharp new hire, except it retains everything and applies it instantly.
Hero isn't an app you go to. It meets you where selling happens.
Ask Hero a question in Slack, in the app, or in a thread. It responds with answers grounded in your deals, not generic AI output.
Talk to Hero the way you'd talk to a colleague. Before a meeting, during prep, or while you're driving to a customer site.
Hero joins your meetings and listens in real time. It surfaces what you need without you having to ask. Battle cards, pricing, competitive intel, proof points. Right there on your screen.
Salesforce, HubSpot, Gong, Outreach, email, calendar. Hero pulls context from the systems you already use and writes back when the call is done. No manual entry. No toggling between tabs.
Vivun is an AI company focused on how sellers actually work. The team behind Hero has spent years studying the moments where deals are won or lost and building technology designed to show up inside those moments, not after them.
Hero is the first product of that work. It's powered by a Sales Reasoning Model built from the ground up for sales, not adapted from a general-purpose AI. Everything about how Hero thinks, learns, and acts was designed around the reality of live selling.
