Sales training: what the numbers say

The finding: the best reps aren't more gifted, they train more

The most telling figure comes from the Salesforce, State of Sales 2026 study: 75% of sales reps reach their targets more easily when they train. In other words, regular practice explains a large share of the performance gap between teams, far more than anyone’s supposed talent.

The sports analogy is telling. A top-level athlete doesn't owe their results to some unexplained gift, but to thousands of hours of supervised repetition. Sales reps work the same way: discovery, the pitch, objection handling and negotiation are moves you can drill. Those who repeat them out loud, in conditions close to the real thing, progress faster and more durably than those who simply “play the matches” in front of real customers.

That is the whole logic of a sales training ground: turning learned theory into reflexes, before the sales meeting really counts.

The forgetting curve: why training alone does not stick

A second figure explains why training has to be continuous rather than one-off. According to the Ebbinghaus forgetting curve, around 70% of training content is forgotten within seven days. However good it is, a one-day course largely fades away the following week if nothing reactivates what was learned.

That is the structural weakness of the “training as an event” model: learning is packed into one or two days, then the field is left to do the rest. But the field does not repeat often enough, or early enough, to embed skills for good.

Regular training reverses that mechanism. By practising in short, closely spaced sessions, the sales rep consolidates memory at the precise moment it was about to fade. That is what our article on the forgetting curve applied to sales education documents, and what fundamentally separates education from training.

• Education: transmits knowledge, over a short period, with rapid decay.
• Training: turns that knowledge into know-how, through practice spaced out over time.
• Both together: education lays the foundations, training makes them permanent.

Results measured at BizCoach AI customers

Beyond sector studies, companies that roll out an AI training ground track their own indicators. Here are three examples from Kestio / BizCoach AI deployments. These figures reflect specific client contexts and are not a generalisable measure.

Score progression. At GL Events, teams gain an average of +5 points between their first and fifth session. That is repetition made tangible: the simulator's detailed scoring grids (9 to 15 criteria rated out of 10) make progress visible, session after session.

Adoption that lasts. At MAIF, training goes beyond 90% weekly adoption. That is a strong signal: a system nobody uses produces no results. The simulator being available at all times (sessions of 5 to 20 minutes, whenever you want) partly explains why it takes hold in daily habits.

Collective buy-in. At Thales, 150 sales reps got on board from day one of a Sales Kick-Off, driven by the platform's challenge dimension. The game mechanics (tournaments, duels, streaks) turn training, so often seen as a chore, into a moment people look forward to.

How to read these figures

Two reading caveats are in order. First, the external statistics (Salesforce, Ebbinghaus) describe underlying trends: they justify the training approach, but they are not measurements carried out by BizCoach AI. Second, the client results quoted come from specific contexts; they show what can be measured, not a promise of identical results for everyone.

What doesn't change is the principle: you don't improve by attending a training session, you improve by practising, regularly, with objective feedback. To compare the options available, our AI sales simulator comparison details the criteria that separate a demo tool from a genuine, measurable training ground.
