Klozers was founded in 2014 by a sales practitioner with 40 years in enterprise B2B sales – including 5 years at Sandler Sales Institute, one of the world’s largest sales training organizations. That experience showed us what traditional training gets wrong. And what actually works.
We use the same methods to sell Klozers that we teach our clients. If it doesn’t work in real deals, we don’t teach it.
⭐⭐⭐⭐⭐ Rated 5 stars from 40+ client reviews [Read what clients say →]
Most sales training companies were started by trainers. Klozers was started by someone who spent 40 years actually selling.
Our founder’s background:
What that means for clients:
We don’t teach theory. We teach what we’ve proven works – in our own pipeline, under real pressure, with real buyers. Every simulation scenario is built from actual deal dynamics we’ve navigated. Every standard we help you install is one we enforce in our own organization.
When we tell you “this is how economic buyers respond” or “here’s what happens when you lead with value,” it’s not from a textbook. It’s from last week.
Years combined frontline enterprise sales experience
Countries where Klozers has delivered enterprise engagements
Years operating in complex B2B sales environments
Over the past decade, we’ve developed proprietary methodologies that solve the problems traditional training creates:
The problem with traditional training: Generic case studies your team dismisses as “not how we sell.”
Our solution: 100% customized simulations built around your actual deals, your market dynamics, your competitive threats.
Every simulation is different because every client’s reality is different.
The problem with traditional training: Knowledge doesn’t change behavior. Two weeks after the workshop, your team reverts to old habits.
Our solution: Enforceable operating standards that define how deals must be run – not suggestions, requirements.
Standards are what make training stick.
The problem with traditional training: No way to track whether execution actually changes in live deals.
Our solution: Currently piloting a governance platform with select enterprise clients.
Status: MVP testing with 3 pilot clients. General availability expected June 2026.
Geographic presence means local understanding: We’re not trying to apply US sales methods to German manufacturing companies or UK professional services. We adapt to how enterprise sales actually works in your market.
We don’t have fancy case study PDFs with exact percentage improvements. We have something better: honest feedback from people who’ve experienced our simulations.
“Highly impactful training. Above all, you leave with your account strategy for the coming year.”
“NO SLIDES = great! Very realistic use case = great! Fun and productive training.”
“This is the first time I have seen such group consensus in a training session.”
“It wasn’t a theoretical training course. I now have a clear overview of my accounts.”
“Interactive, not boring with tonnes of PowerPoint slides. I now have a clear direction to follow for prospecting.”
“Overall, super interesting training. Very positive group cohesion. No blah blah blah, which is nice!”
“I didn’t notice the time passing, which is a very good sign! I can’t wait to refocus on what we’ve learned.”

Enterprise clients have achieved measurable improvements in forecast accuracy, pipeline quality, and deal value within 90 days of implementing our simulation and standards methodology.
Four Things You Won’t Get From Traditional Sales Training Providers
If slides don’t work in your sales calls, they don’t work in our training. Every simulation is experiential – your team makes decisions, faces consequences, and learns from outcomes. Not from watching a trainer click through decks.
Before every simulation, we interview your sales leaders and top performers to understand your actual deals.
Then we build scenarios around your market, your buyers, your competitive threats.
Your team can’t dismiss it as “not relevant to us” – because it’s built from your world.
We Go To Market using the same methods we teach. Our founder spent 40 years in enterprise B2B sales – including 5 years delivering training at Sandler – before starting Klozers.
When we tell you “this is what works,” it’s because we’re doing it right now. In our own pipeline. With our own prospects. Under the same pressure you face.
Most training stops at teaching methodology. We go further: we help you install enforceable operating standards that govern how deals must be run.
Knowledge alone doesn’t change behavior. Enforcement does.
Each member of the Klozers leadership team has operated inside enterprise sales environments at a level where execution quality carries direct commercial consequence.

Across engagements in Manufacturing and Technology, working with sales organisations of 100 to several hundred revenue-generating roles, certain patterns appear consistently. These are not edge cases. They are structural — and they are what Enterprise Sales Operating Standards are designed to address.
Organisations with well-funded training programmes still experience inconsistent qualification, optimistic pipelines, and unpredictable forecasts. The issue is not capability – it is the absence of enforceable standards that define what must happen.
In most enterprise sales organisations, what “qualified” means varies by manager, by territory, and by individual seller – producing pipeline stages that reflect internal activity rather than buyer validation and forecasts built on confidence rather than evidence.
Without explicit standards, pipeline reviews default to subjective conversation and forecast discussions focus on sentiment rather than evidence – leaving leadership with no consistent basis for validating how opportunities are actually being run.
Klozers has delivered enterprise sales engagements with organisations across Manufacturing, Technology, Financial Services, and professional services.










If you are responsible for governing complex sales opportunities and execution variance carries material commercial risk, the next step is a structured conversation.
