What We Do

Sales Growth

As Trusted Advisors we provide Exec support to fastrack Sales Growth and move the business up multiple levels.

Sales Consulting

Working as a safe pair of hands, we undertake project based sales engagements with defined outcomes.

Sales Training

Open and In House sales training courses for Business Development, Account Management & Entrepreneurs. 

Sales Coaching

1-2-1 and Group Coaching for Salespeople utilising our unique Work Based Learning system.


Our sweet spot is helping companies develop sales campaigns and then using those campaigns to provide real life training scenarios for their teams.  We especially like helping small and mid-market companies take on the giants and big brands in their industry. 

The sales campaigns we work with our clients to create are simple, straightforward and effective.  They range from simple campaigns for technology services, SaaS and more complex Enterprise sales to large multinational corporations.  

Our approach keeps salespeople out of the “classroom” and focusses on learning by doing.  Everything we do is supported by live coaching where we are supporting sales teams when they need it the most. 

We love sales and have a very practical and hands on approach.  Hence one Microsoft Business Manager described Klozers as the ‘Sat Nav for Sales Success’. 


With a combined experience of over 100 years in B2B sales, the Klozers team have worked with Startups, SMEs, Mid Market and Enterprise Organisations such as Microsoft, RBS & Vodaphone.

In addition to the many Technology companies we have worked with, we have also supported businesses in Telecoms, Insurance, Financial Services, Manufacturing, Business Services, Oil & Gas. 

We provide Adjunct Teaching Support to the Masters in Entrepreneurship programmes at Strathclyde Business School.

In addition to working locally we have clients throughout the UK, mainland Europe, the USA & Canada.

Why we're different


Traditional training companies focus on Outbound which is great, but it’s only half the jigsaw.  With over 200 keywords on the first page of Google, we know exactly how to generate inbound sales leads.

We practice what we teach

We only teach the proven strategies and tactics we use in our own business.  This gives us a deep understanding of exactly what works and what does not.

We're just like you

We are just like you.  We are ambitious and growing fast – join us at one of our live events in London, Berlin or Mumbai – we would love to meet you.
