Performance visibility layer for sales teams

Your managers aren't bad coaches. They just never know what to coach.

Other tools tell you what happened. Zell tells you what to do.

Zell listens to every real call, scores the selling behaviours that actually move deals, and hands each manager a ranked list of what to coach — with the training already built.

Dave: Rep talked 68% of the call. The buyer never got room to surface budget. Coach the "ask, then stay silent" drill — I've queued a 4-minute simulation.

How it works

From a real call to a ranked coaching plan — automatically.

Zell sits between your CRM and your conversation data, doing the operational work of a sales manager while the strategy stays with your people.

01

Analyse every real call

Video, phone or in-person — transcribed on-device and GDPR-compliant. No behaviour goes unseen, no rep gets missed.

02

Score the selling behaviours

Zell scores what actually moves deals and surfaces the skill gaps across every rep and team — ranked, not buried in a dashboard.

03

Coach with Dave, automatically

Dave, Zell's AI coach, builds a personalised plan and role-play simulations targeting each rep's exact gap — ready before the next 1:1.

What would Zell tell you to coach?

Score a call the way Zell does. Move the sliders — or drop in a rep profile — and Dave finds the one gap holding the deal back, plus what it costs you in days-to-first-sale.

The platform

Everything a sales manager does at scale — without the guesswork.

Real-call analysis

Every video, phone and in-person conversation scored — not a hand-picked sample.

Skill-gaps dashboard

See exactly where each rep and team is losing deals, ranked so managers act on the biggest lever first.

Dave, your AI coach

An assistant that writes each rep's coaching plan and answers "what do I work on next?" instantly.

Targeted simulations

AI role-plays built from the rep's actual gap — practice the exact moment they fumbled, before the next call.

Sits between CRM & calls

Plugs into the stack you already run and automates the operational work, leaving strategy with the manager.

GDPR, on-device

Transcription runs on-device and stays compliant — European data handling built in from day one.
