If you have secured investment, built out a marketing and sales team, and your board or investors are still asking why pipeline is not where it should be, you are not alone. I hear this from CEOs and MDs more often than almost anything else.

This guide looks at why marketing stops delivering once a business scales, what commercial accountability should actually look like, and how to get marketing, sales and customer support working as one team again.

Why does marketing stop delivering results as a business scales?

In my experience, it almost always comes down to one of two things. Either marketing has not been given clear commercial objectives, so activity continues without anyone being able to say what it has actually achieved. Or the function has grown faster than the structure underneath it, so spend and headcount have increased without a corresponding increase in accountability.

Neither of these is a reflection on the people involved. It is a structural problem, and structural problems need a structural fix, not more activity.

What does commercial accountability in marketing actually look like?

It means marketing can show, in commercial terms, what it has contributed to the business. Not impressions or engagement. Marketing qualified leads, pipeline value, conversion rates and the cost of acquiring a client.

If your marketing team or agency cannot answer those questions clearly, that is the first thing to fix, before anything else changes.

•A defined marketing qualified lead - Sales and marketing need to agree, in writing, what counts as a good lead. Without this, the two teams will always disagree about performance.

•A visible pipeline contribution - Marketing should be able to show which deals it influenced and at what stage, not just how many forms were filled in.

•Regular reporting against commercial KPIs - Monthly or quarterly, tied to revenue and pipeline, not vanity metrics.

•Clear ownership - One person accountable for marketing performance, reporting directly into commercial leadership.

When investors or board members ask what marketing is doing, the answer should already exist as a report, not require someone to assemble it under pressure.

How do I get marketing, sales and customer support working as one team?

Most scaling businesses I work with have all three functions in place, but they operate as separate departments with separate goals and very little shared information. That is usually the real source of underperformance, more than any individual team's effort.

Marketing creates content sales don’t use. Customer support holds insight which doesn’t make it back into messaging. Systems and tools exist but aren’t adopted. Each team is working hard. None of it adds up to a coherent commercial engine.

Fixing this is less about new tools and more about shared definitions and shared visibility. The three teams need to agree what a qualified lead looks like, share a common view of the pipeline, and have a mechanism where customer insight feeds back into marketing and sales activity.

What systems and processes does a scaling STEM business need?

As a business grows, the systems that worked at ten people start to break at fifty. The most common gaps I see are a CRM that is not actually used consistently, no shared definition of the sales funnel stages, and marketing activity that is planned separately from sales targets rather than built around them.

None of this needs to be complicated. It needs to be consistent and embedded across all teams. A simple, well-used system will always outperform a sophisticated one that only half the team trusts.

The starting point is usually a commercial growth review: a structured look at what is working, what is not, where the accountability gaps are, and what needs to change first. This gives you a clear, evidenced basis for decisions, rather than relying on instinct or internal politics.

How do I report on marketing performance to investors and the board?

Investors and stakeholders want to see a clear line from marketing activity to commercial outcomes. That means leads generated, cost of acquisition, conversion rates by stage, and progress against the targets that justified the original investment.

The businesses that handle this well are the ones that have already built the reporting into how marketing operates day to day. The businesses that struggle are the ones trying to construct a narrative retrospectively, usually a few days before a board meeting.

If you are not confident your current reporting would hold up to scrutiny, that is worth addressing before it becomes a bigger issue than the marketing itself.

Frequently asked questions

These are the questions I get asked most often by CEOs and MDs who have outgrown founder-led marketing and are looking for scalable growth.

Why is my marketing team or agency not delivering results?

Usually because objectives have not been clearly defined in commercial terms and translated into a strategic marketing plan, so there is nothing concrete to measure performance against. Start by agreeing what a qualified lead looks like and what marketing is actually accountable for. Most performance problems are accountability problems first.

How do I improve alignment between marketing and sales?

Get both teams to agree, in writing, on the definition of a qualified lead and the stages of your sales funnel. Get the teams meeting together and ask what is working, what could be better and agree priorities to meet targets. Most misalignment comes from each team quietly working to a different definition of success. A shared pipeline view and a regular joint review meeting solve most of the friction.

What should I check first if marketing spend feels out of control?

Look at what each channel or activity is actually contributing to pipeline, not just what it costs. Many scaling businesses keep spending on channels that built early traction but no longer deliver meaningful results..

If a channel appears strategically important but is underperforming, examine the tactics before cutting the budget. The issue may be the execution rather than the channel itself.

Rather than viewing marketing purely as a cost, consider the longer-term value being created. Most businesses are happy to invest significant sums when there is a clear return, whether that's revenue growth, market share, customer acquisition or brand strength.

A commercial growth review can usually identify these issues within a few weeks, helping leaders make more informed decisions about where to invest, optimise or stop spending altogether.

How long does it take to fix a marketing function that is underperforming?

It depends on the underlying causes. An initial review will often identify the key issues within a few weeks, whether they relate to strategy, team capability, processes, systems, measurement or alignment with sales.

Some improvements can be seen relatively quickly. For example, clarifying objectives, agreeing success measures and improving reporting often creates better visibility within one or two reporting cycles.

However, meaningful change usually takes longer. Implementing new processes, improving team performance, strengthening sales and marketing alignment, and embedding better ways of working can take several months. In more complex organisations, or where there are long sales cycles, it may take six to twelve months before the full impact is visible.

The goal is not simply to fix marketing activity, but to build a marketing function that can support sustainable growth.

Do I need to bring in a fractional CMO to fix this, or can my existing team do it?

Often the people are right and the structure around them is wrong. A fractional CMO brings an independent outside view, can diagnose where accountability is breaking down, and can put the right reporting and process in place without the cost or risk of a full-time senior hire.

Not confident your marketing is delivering what it should?

I work with CEOs and MDs of scaling STEM businesses, science, technology, engineering, mathematics and manufacturing, to diagnose where marketing is breaking down and put commercial accountability back in place. A commercial growth review is usually the fastest way to find out what is actually happening and what to fix first.
