Value-based key account management

We help you develop the value in your key accounts.

Maximise the value you create at your key accounts. Learn how to innovate the offer, develop the relationship and capture your share of the value, with plans that update themselves while you sleep. We bring the method, the training and the tools.

Consultancy, programmes and tools from Mark Davies and Richard Brooks.

Create the value. Sell it. Keep it. One cycle behind every programme, plan and tool we build. Roll over a circle to explore.

Try the method in a minute

What is this customer really worth?

Revenue tells you what a customer paid you. It says nothing about what they spent, what they did without you, or what they never did at all. Four numbers, and the account lands in one of four strategies. The example is filled in; put your own customer over it.

What we work on

Four things decide whether key accounts pay off.

Four out of five sales organisations rebuild their key account programme every few years (Gartner, (re)building KAM programmes for growth, 2021). The missing ingredient is capability, not effort, and everything we do builds one of these four.

01

The offer

The most important thing. A customer value proposition your key customers would pay more for, built from what they are trying to achieve, not from your product list.

02

The account manager

The most important person. Strategist, operator and business developer in one role, and almost never trained for all three.

03

The culture

The hardest thing. KAM fails quietly when the rest of the business treats key customers as sales' problem. We work on the organisation, not just the team.

04

The AI

The thing changing everything. Not a bolt-on module: practical adoption inside the planning, the research and the proposition work your team already does.

“Key Account Management is the continuous delivery of value through the intersection of sales, strategy and innovation.”

Brooks, Davies and Holt, Creating Customer Value Propositions with AI (Kogan Page, 2027)

The programme
Who we are

Value Matters.

Three people who have spent their careers on the same question: what makes a customer keep choosing you, and pay you properly for it? We met through Cranfield, where we all still teach. Mark spent a career proving that value-based KAM works, Sue researched and taught it to a generation of key account managers, and Rich builds the tools that take the admin off. Practice, rigour and technology, one argument. It is on one page: our philosophy.

The tools

A suite of bespoke tools.

We have built a set of tools on the best AI and technology available, each one shaped around the method. They extend what a key account manager can do: the research and planning that used to take a week, the value opportunities that used to go unnoticed, and the proposition tested before the customer sees it. Start with the free ones. Licence the rest when they earn their keep.

How we teach

You'll laugh. And learn something.

We teach busy people, which means we compete with their phones. People rarely adopt tools they were sent a manual for; they adopt tools they have enjoyed using. Ten minutes of play does more for confidence than an afternoon of training slides. So we made these, and we mean it. It is also why people book us to speak.

The books

Published, not just practised.

The thinking on this site is published, peer-reviewed by the people who buy it, and taught at Cranfield. Three books already in print, and the fourth, the book of the method itself, coming from Kogan Page in May 2027.
