SellifyTrain
Three or four minutes. No talking needed yet.
Tap-through drills you can do on the bus, in a queue, between calls.
You have to say it out loud.
Sellify puts you in a real conversation with a buyer who talks back — then scores you on the price you actually got, not on how you sounded.

Hear one
This is the part you can't practise alone
Forty seconds of a Deal in the first Arena. He wants the car and hates the price, and nothing he says is on rails.
MarekSo what's the best you can do on it?
YouBefore I answer that — you were on the forecourt by nine this morning. What is it about this one?
Marek…It's the only one in the colour my wife will accept. Don't tell her I said that.
YouThen let's not lose it over a few hundred. What number did you have in your head?
MarekSixteen. Sixteen and I'll take it today.
YouI can't do sixteen. I can do eighteen four with the twelve-month warranty included — which is the bit you'd be paying for separately in March anyway.
Marek…Eighteen four, with the warranty.
MarekFine. Where do I sign?
A sample Deal. In the app you speak this part.

The score is whatever he agrees to. Nobody has agreed yet.
The problem
You already know where it falls apart
You run out of questions and start pitching.
They push, and you drop the price to keep them.
You answer the objection they said, not the one they meant.
The conversation just… ends.
None of that is a knowledge problem.
You knew what you should have said. You worked it out about four hours later, in the car. The gap is not what you know — it is that the moment arrives faster than you can think, and the only fix for that is having been there before.
One in nine people sells for a living. The other eight sell anyway — 41% of the working day, spent persuading and convincing other people.

Why this
You cannot read your way out of a conversation
Selling is closer to a motor skill than a subject. Knowing the theory of a price objection has never once stopped somebody folding on price, because folding happens in the second and a half before you have finished thinking.
A bookcan't interrupt you.
A coursecan't push back on price.
A colleaguegoes easy — they know you, and they have to see you tomorrow.
Marekdoes not go easy, and has never met you.
And the score is not an opinion
The buyer paying 18,400 is a fact. A model saying “good discovery” is an opinion. The moment an opinion can move the number, the number is fakeable — so your score is the price he agreed, as a position between the worst and best the scenario allows. Nothing else is allowed to touch it.
Coaching comes from a separate pass over the transcript. It tells you what to practise. It never moves your score.
Caved · £14,200Earned · £21,000
62out of 100 — because £18,400 sits 62% of the way up the band he was willing to move through.
How it works
Drills, then one real call
A day in an Arena is a short path of cheap drills that unlocks exactly one live Deal, last. One ranked stage per Arena per day — you cannot buy tomorrow's.
Four drills · about four minutesOne live Deal
62out of 100 — the price he agreed, not a verdict on how you sounded.
Sell
Somewhere you can speak makes this a lot better.
You talk. He answers. Nothing is on rails and he can walk away.
Scored
The score is the price you got — not an opinion of how you sounded.
Then a read on what to practise, with your own lines quoted back.
You start in Automotive and buy your way up with commission you earned — Real Estate, SaaS, Recruitment, Government, then two endgame layers. Money buys access, never performance.
Who you're up against
They don't go easy on you
Buyers are characters, not scenario settings. They come back across stages and later across Arenas, so beating Marek once means something the next time he walks in.
Wants the car, hates the price
Marek
Found the car online at seven this morning and was on the forecourt by nine.
One more discount and she'll think about it
Dee
Friendly, relentless, and has never paid list price for anything in her life.
Will not say what is actually wrong
Sofia
Polite about everything, enthusiastic about nothing. Something is bothering her.
The CFO who has never said yes
Gordon
Signs things. Enjoys not signing things more.
Priya brought a printed comparison table. Ray is already late for a budget meeting. Bex is still just looking.
The quiet part
You can lose fifty deals and nobody ever knows
Practising a conversation means being bad at one, out loud, in front of somebody. That is why almost nobody does it — not because reps don't work, but because the only room available has your manager in it.
No one is watching
No roleplay in front of the team. No manager scoring you. No colleague who will remember it at lunch.
No booking anyone
Seven in the morning, on the sofa, between two real calls. He is already there and he never reschedules.
No consequences
The worst thing that happens is a low number on a screen that only you can see. Then you go again.
Before you ask
Questions
Do I actually have to talk out loud?
For the Deals, yes — that's the entire point. The drills in between are tap-only, so you can train anywhere and save the talking for when you're somewhere you can speak.
Can I play it on the train?
The drills, yes. A Deal needs somewhere you can speak normally. It's a conversation, and whispering at a stranger's car does not go well.
Do I need smart glasses or a headset?
No. Sellify uses your phone's own microphone and speaker. There is nothing to pair and nothing to buy.
I've never sold anything. Is this for me?
Yes. You say how much experience you have when you start, and the buyers after your first one adjust to match. Say you're new and they'll go gently.
I sell for a living. Will it be too easy?
Say so at the start and they play brutal. Ask for a hard buyer and the app takes you at your word.
What does it actually measure about me?
Five things, and only where the call gave evidence for them: discovery, listening, pitching, negotiation and closing. A single call evidences two or three, never all five — and a rating from one Deal is labelled an early read until there's enough evidence to firm it up. Whether the buyer told you the real thing is reported as a quoted moment, not a number, because it's binary and a score would fake a precision that isn't there.
What are the Arenas?
Eight selling worlds you work up through — Automotive, Real Estate, Retail, Professional Services, SaaS, Recruitment, Industrial, Government — then Global Deals and one more that isn't explained. You buy into each with the commission you earned selling in the last one.
Can I pay to get better?
No, and that's deliberate. Money buys access to new Arenas and extra Deals. It cannot buy XP, skill ratings, or an easier buyer, and it cannot buy tomorrow's stage.
Is it on Android?
Not yet. iPhone only for now.
The live conversation runs on Extentos, which is why a Deal works over your phone's own microphone and speaker, with nothing to pair.
