The 5-minute daily review
Every morning, a short exercise on moments from yesterday’s calls: spot the slip, pick the better line, then get a tip from Flare, Zell’s AI coach. Streaks keep it a habit.

What Zell does
Your recorder stores what happened. Zell changes the next call.
It’s not a people problem. Manager time just can’t be the coaching system. Zell runs the loop on every call, for every rep, and pays off the behaviours you agreed on.

Why the feedback is different
Feedback that sounds like your best manager.
Generic AI feedback gets ignored. When a manager disagrees with Flare, Zell’s AI coach, they reply to it on the call. Flare learns from that, so the next feedback sounds like the manager.
01
Managers just reply to Flare
Flare is Zell’s AI coach. If a piece of feedback is off, the manager replies right on it in the call and says what’s wrong. No setup, no separate training step.
02
Flare learns from every comment
Each comment is fed back into the model. Flare picks up what your managers care about and how they say it, so its feedback starts to sound like them.
03
Nothing to maintain
The system improves itself. It doesn’t repeat a mistake a manager has flagged, and scorecards keep themselves up to date.
Illustrative example. Names and calls are made up.
Why Zell
You already record your calls. Then what?
Consistent coaching still depends on manager time, and managers don’t have it. Recordings show what happened; Zell changes what happens on the next call.

Testimonials
What sales teams say about coaching with Zell.
I've been using Zell to get coached on my sales calls, and it's made a real difference. I can see my progress day after day, and the feedback on my sales style is spot on. Not generic tips, actual actionable notes I can use on the next call. When an AI tool moves your KPIs, you say it out loud. This one did.
Maya BentaharBusiness Development France
In a very short time—just a couple of months—we made that new type of commercial offer the standard. At least ten new sales reps have joined since we began using it—with zero issues. They complete the role-plays, and the sales manager knows exactly how prepared they are.
Tommaso Mari
For us, fast SDR onboarding is critical. We’re constantly starting new projects, and Zell lets new reps get productive in days instead of weeks
Julius DanyCEO
I was able to double, maybe triple my bookings because I followed the tips Zell gave me.
Diego P.BDR
Zell helped us reduce time to first sale from 180 to 105 days. We also use it during hiring to assess how candidates actually sell, not just how they interview.
Pietro PicognaCEOZell dramatically improved how we onboard and train SDRs and AEs. Reps use it daily to practice calls, and managers can scale coaching without extra effort. The platform has massive potential, and the team behind it is exceptionally responsive

Questions sales leaders ask us
The honest answers to what usually comes up on a first call.
We already use Gong. Why do we need Zell?
Gong records and summarizes. Zell sits on top of your recordings and turns them into coaching: every call scored against your playbook, one focus per rep, practice drills and 1:1 prep for managers.
Can’t we just build this with ChatGPT or Claude?
You can analyze a transcript with a prompt. What’s hard is a consistent score that you can trust over months, with a workflow reps and managers actually use. Zell keeps that consistent and learns from your managers’ comments.
Will the scores match how our managers judge calls?
Scorecards are built around your methodology. When a manager disagrees with a piece of feedback, they reply to Flare, our AI coach, right on the call: what’s wrong and why. Flare learns from every comment, so the feedback gets closer to how your managers judge and how they speak.
Don’t AI role plays get repetitive?
Personas vary in mood, objections and difficulty, and the scenarios come from your own calls. Reps practice the exact moment they struggled with.
How do you make sure reps actually follow the feedback?
We define the approach with your team first, so reps buy in and see the value for themselves. Zell then delivers feedback where it’s easiest to use: after calls, during calls, and on the channel they already use, like Slack or WhatsApp. Reps earn commission for following the agreed behaviours and engaging with the feedback.
Will reps feel watched?
Feedback is developmental: private, specific and focused on one thing to improve. Better calls mean better-qualified meetings and more commission.
What happens to our call recordings?
Everything is hosted inside the EU. By default, recordings are stored securely so reps and managers can replay the moment. If you prefer, Zell can also work without storing voice recordings. Anonymisation is available, and our sub-processors and DPA are public.
How much setup and maintenance does it need?
We set up your first scorecard with you from your playbook. After that, the system improves itself: managers reply to feedback they disagree with, Flare learns from it, and scorecards keep themselves up to date. Nothing to maintain.
What does it cost?
Pricing is per rep per month and depends on your team size. Book a demo and we’ll send you a quote for your team.
