The Bottom Line: Ava by Vivun is an AI sales teammate built by founders with 25+ years in technical sales. It’s not a call summarizer—it preps you before meetings, answers complex questions in real-time during calls, and generates the follow-up materials after. Enterprise teams at DocuSign, Dayforce, Gladly and Cloudera are already using it to scale technical sales capacity without scaling headcount.
Importantly, the founders were Sales Engineers themselves. Ava has been built to AI the SE process from Day 1.

Quick Backstory
CEO Matt Darrow built presales at Zuora through their IPO. When generative AI threatened to make Vivun’s original product obsolete, he didn’t protect the old thing—he pivoted hard into building Ava. The AI agent is now doing eight figures in ARR and tripling.
What Makes Ava Different
Most AI sales tools are still just glorified chatbots. They summarize calls. They write follow-up emails. Fine.
Ava is built differently because the founders actually understand how technical sales works. They call it the “Sales Reasoning Model”—the AI knows the difference between a champion and a buyer, understands how complex deals progress through buying committees, and connects insights across conversations instead of treating every interaction as isolated.
Three modes:
Before the call: Ava researches the account, pulls insights from your CRM, email, Slack, and external sources, builds stakeholder maps, and creates prep docs so you know who you’re meeting and what matters to them.
During the call: Ava joins your sales calls to surface real-time insights and answer complex product or competitive questions on the spot. The “let me get back to you” killer.
After the call: Summarizes discussions, drafts personalized follow-ups, and creates next-step materials—value cases, solution docs, deal reviews.
The Tech Stack Integration
This is where it gets practical. Ava connects to:
- Salesforce for CRM data and deal context
- Gong/Chorus for call intelligence
- Slack for team communications
- Google/Microsoft for calendar and email
- Clari for forecasting data
It’s not asking you to rip out your stack. It sits on top and makes everything smarter.
Who’s Actually Using It
DocuSign. Dayforce. Cloudera. F5. ServiceTitan. Gladly. Coder.
These aren’t startups experimenting with AI. These are enterprise sales orgs with complex deal cycles betting on Ava to scale their technical sales capacity.
From the Coder case study: “One of the things that’s been incredible with Ava has been our capacity to actually automate win reviews and create an artifact with all the detail—but backed by referenceable customer quotes, at that level of detail.”
From Dayforce: “It has been remarkable to see Ava accomplish what we never would have thought possible in primarily intellectual space of sales. I love that we can treat her like a new hire, train her easily and then her capability is scalable to an infinite number of sales opportunities.”
The Real Question for Sales Leaders
The AI sales agent space is getting crowded. There are multiple “Avas” now, plus Agentforce, plus everyone else claiming to automate selling.
What matters:
- Domain expertise. Does the team actually understand technical sales, or are they applying generic AI to sales workflows? Darrow and Bruce have 25+ years doing this work themselves.
- System of record integration. Can it plug into your existing stack without a six-month implementation? Vivun claims minutes, not weeks.
- Actually doing the work. There’s a difference between AI that summarizes what happened and AI that helps you execute in real-time. Ava aims to be the latter.
Who Should Look at This
- Enterprise sales teams with complex, technical sales cycles
- Organizations that can’t hire enough sales engineers to cover demand
- Companies where “let me get back to you” is killing deal velocity
- Sales leaders trying to scale technical expertise without scaling headcount
