Hero was built for the
person on the call.
Not the manager reviewing it later.
Not the ops team reporting on it.
Not the analyst scoring it.
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 AI in sales was built for a different job.
It records calls. It scores performance. It writes emails. It automates sequences. These things have value. But none of them help you when a buyer asks a question you didn't expect, and you have three seconds to answer.
Most sales AI operates around the selling moment. It analyzes what already happened. It automates what doesn't require judgment. It reports on outcomes after the fact.
Hero was built for the moment itself. The live conversation where credibility is tested, momentum is created or lost, and the deal either moves forward or quietly stalls.
It's not a chatbot or an AI assistant.Hero is a teammate.
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.
Built to think like your best sellers do.
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.
It understands, not just retrieves.
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.
It shows its work.
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.
It remembers the full arc of the deal.
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.
It acts, not just responds.
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.
Brief Hero like a new teammate.
You don't configure Hero through a settings panel or a support ticket. You train it through conversation. Give it your products, your positioning, your competitive landscape, and your sales process. It learns the way a sharp new hire would, except it retains everything and applies it instantly.
When your messaging changes, update Hero once. It applies that update to every conversation, every deal, every call. No cascading dependencies. No waiting for IT.
Hero also gets sharper on its own. The more your team uses it, the more it learns about what works. It picks up patterns from real conversations and applies them across the team.

Where you work.
When you need it.
Hero isn't an app you go to. It meets you where selling happens.
Text and chat
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.
Voice
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.
Live on calls
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.
Connected to your tools
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.
Hero is built by Vivun.
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.
