Half the money I spend on advertising is wasted. The trouble is, I don't know which half.
— John Wanamaker, c.1900
He was being optimistic.

Your pipeline is thin. It's not a marketing problem.

Most B2B businesses are running a very expensive illusion. They have a marketing team, a budget, campaigns running on multiple channels. They measure impressions, click-through rates, engagement metrics and follower counts. At the end of the year, the marketing team produces a polished presentation full of graphs pointing upward.

And yet the pipeline is thin. The leads are low quality. Revenue growth is sluggish. Nobody can explain the disconnect.

The explanation is simple: most of what is being called 'marketing' is not generating revenue. It is generating activity. And in business, activity without commercial output is just cost.

The lines that make
marketing directors uncomfortable.

CH.01
"The fix is not more creativity, more channels, or more spend. The fix is structural."
Executive Summary
CH.05
"The conflict between marketing and sales is not a personality problem. It is a structural one. And it has one structural solution."
The Reporting Problem
CH.08
"A poor website will cost you clients. A good website will not win you clients. It will simply avoid losing them."
Your Website
CH.10
"When you see marketing spend increase rapidly in a struggling business, you are usually watching the final act."
The Death Spiral
CH.12
"Viral marketing does not require a big budget. It requires the courage to approve something that makes the room uncomfortable."
Viral Marketing
CH.11
"Never try to create a new message to sell a product into a market that does not already recognise the problem it solves."
Pain Equals Solution

The 4-Step
Practical Audit

The book ends with a concrete process. Do it honestly and you will know exactly what to change — and where to move the money.

"The goal is not to spend less on marketing. It is to stop spending on things that feel busy and start spending on things that produce qualified conversations."

— Miles Corrigan, Conclusion

01

Map every marketing activity and its true cost

List everything — including internal time at fully loaded cost. Most businesses underestimate by 40%.

02

Trace your last 20 clients back to their origin

Where did the relationship actually begin? Not where they first saw your name. Where the first real conversation started.

03

Connect origin to cost

The mismatch between spend and source is your wasted 80%. Visualised, concrete, undeniable.

04

Redesign the allocation

Move money toward what demonstrably produced clients. Cut what produced nothing — regardless of how professional it looks.

Three decades in the engine room of B2B commercial growth.

Miles Corrigan has spent his entire career building sales teams from scratch, turning around underperforming pipelines, and advising leadership teams across a wide range of sectors on the strategies that actually produce revenue rather than activity.

This book is written entirely from lived experience. Every principle has been tested in real organisations, with real budgets, real boards asking hard questions, and real consequences when the answers were wrong. There are no borrowed frameworks, no academic citations, and no theories that have not been stress-tested against a quarterly target.

Miles's view of marketing is unapologetically commercial. He has sat in too many board meetings watching marketing budgets grow and pipelines stagnate to have patience for activity that cannot demonstrate a credible connection to revenue. His frustration with that pattern — and his conviction that the fix is structural rather than creative — is what drove him to write this book.

Stop funding the
80% that doesn't work.

A practical field guide for sales directors, MDs, founders and anyone responsible for revenue growth in a B2B business.
