Della vs Vivun
By the Della AI team · Updated
Della and Vivun solve different problems. Vivun, known for presales and sales engineering software, now leads with Hero, an AI teammate that preps enterprise deals, answers technical and product questions on calls and writes the follow-up. Della is built for phone sales teams: objection answers from your own script mid-call, AI role-play practice, and every call scored.
Who each tool is for
Vivun is for: Enterprise account executives, sales engineers and enablement teams running complex B2B deals, where buyers ask detailed product, security and integration questions and each opportunity needs research, meeting prep, follow-up and CRM updates. Hero also has an individual plan for a single seller.
Della is for: Phone sales teams of 5 or more sales reps (cold calling, appointment setting, inside sales) where the deal is often won or lost on a single objection, and managers want every call scored and reps practicing on real objections.
What Vivun does
Vivun has been known for presales and sales engineering software. Its website today (read October 24, 2026) leads with Hero, which it calls “the AI sales teammate fast enough to help you win the live call.” Before a call, Hero pulls account context from the CRM, past calls, docs and the web into a meeting brief, and lists roleplay for practicing deal scenarios on real deal context.
During the call, Hero transcribes without a bot joining and shows private suggested answers to questions, objections and follow-ups in a “Whisper” mode only the rep can see, using deal context, product knowledge and competitive intelligence. Its page for sales engineering and enablement teams says it answers technical and integration questions live, surfaces the battle cards the team wrote when a competitor comes up, guides reps through methodologies such as MEDDIC or Challenger, and captures technical commitments for the handoff to implementation. That page says Hero does not replace SE involvement.
After the call, Hero gives coaching feedback, writes the summary and action items, creates deal content and updates the CRM. Its pricing page names connections to Salesforce and HubSpot (read and writeback), Google Workspace, Microsoft 365, Slack, Notion, Zoom, Apollo, Outreach, Seismic and Intercom, plus an MCP server. Enterprise adds Voice and Avatar modes, where Hero speaks up or joins a video call as a visible teammate. A dialer is not described.

What Della does
Della is an AI sales coach for teams of 5 or more sales reps who sell on the phone. It has two parts, and every plan scores every call automatically.
Della Live (real-time objection handling) listens to the call and, when a prospect raises an objection, puts the answer on the rep's screen mid-call. The answers come from your team's own script and objection answers, so reps say what your best closer would say, not a generic line.
Della Practice (AI role-play) gives reps an AI voice prospect to call between live calls. The objections they rehearse come from the objections your team hears on real calls, and every session gets a score.
Della includes a built-in dialer with live objection answers, call scoring and practice in every seat. Already have a dialer? Tell us which one and we'll confirm whether Della can work with it. Setup is done for you: we load your script, build the objection library from your call recordings and set up the practice scenarios, which takes about a day. See how Live and Practice work together.

Who should pick Vivun instead
- Your sellers run long enterprise deals where buyers ask detailed product, security and integration questions, and your sales engineers cannot join every call.
- You want help across the whole opportunity: account research, meeting prep, follow-up content, stakeholder mapping and CRM updates.
- Much of your selling happens in video meetings, and you want options such as an AI teammate that speaks or appears on the call.
- You are a single seller who wants to try an AI assistant on your own calls for $20 a month.
Who should pick Della
- You run a phone sales team of 5 or more sales reps making many short calls a day, and the deal turns on handling the objection in the moment.
- You want live answers built from your team's own script and objection answers, set up for you in about a day.
- You want every call scored automatically on every plan, plus AI role-play on the objections your reps actually hear.
- You want a built-in dialer, published per-seat team prices, a 7-day free trial and the option to buy online without a sales call.
How to decide
This is rarely a head-to-head choice. Vivun is built around complex enterprise opportunities and the technical knowledge that sales engineers hold; Della is built around the phone sales floor, where reps dial all day and the moment that matters is the objection. They solve different problems, and a company with both an enterprise AE and SE team and a phone sales team could reasonably use both: Hero for the enterprise deals, Della for the dialer.
If you are choosing for one team, look at the calls themselves. Long, scheduled meetings with detailed technical questions point to Hero. High-volume outbound or inbound phone calls where reps need the right line for ‘not interested’ or ‘call me later’, plus scoring and practice, point to Della.
