How to Build a Marketing Function From Scratch

· 8 min read · By

Most B2B companies don't start with a marketing team. They start with a founder, a product, and a handful of early customers who came through personal networks, referrals, or sheer hustle. That works for a while. But there comes a point where the business needs marketing to do the heavy lifting, and there's nothing in place to make that happen.

Building a marketing function from scratch is one of the hardest things a growing company can do, mostly because it requires making decisions about things the leadership team has never had to think about before. What should we invest in first? How do we know what's working? And who should be making these calls?

Why most companies get it wrong the first time

The pattern is remarkably consistent. A company reaches the point where it needs marketing. Someone hires a junior marketer, or engages an agency, or starts running ads. Activity starts, but there's no strategy connecting it to revenue. Six months later, nothing has moved and the company is back to square one, except now it's spent money and time with nothing to show for it.

Getting the foundation right matters more than speed. Many businesses at this stage find that working with a marketing systems support gives them the experienced direction they need without over-committing before the model is proven. Investing in brand positioning early is one of the highest-leverage moves at this stage. The patterns are closely connected to the dynamics we explore in when founder-led sales stops working.

The reason this keeps happening is that companies jump to execution before they've answered the strategic questions. What's our positioning? Who exactly are we selling to? What does the buying journey look like? Which channels will actually reach those people? What does success look like in month three versus month twelve?

These aren't trivial questions. They require experience and judgment that most scaling companies simply don't have in-house yet. And getting them wrong is expensive, not because of the direct cost, but because of the months lost going in the wrong direction.

The positioning problem

Positioning is the foundation that everything else sits on. Your messaging, your content, your campaigns, your sales conversations. All of it depends on having a clear answer to one question. Why should someone choose you?

Most companies at this stage don't have that nailed down. The founder can explain it brilliantly in person, but it hasn't been codified into something that works without them in the room. That gap between what the founder says and what the website says is where deals go to die.

Getting positioning right isn't a quick exercise. It requires a deep understanding of the market, the competition, and the customer. It's strategic work, and it's the kind of work that shapes every marketing decision that follows.

The hiring dilemma

One of the trickiest decisions at this stage is who to bring in first. The options all have trade-offs.

**A junior marketer** is affordable but won't be able to set strategy or build a function from nothing. They need direction, and there's nobody to give it to them.

**An agency** brings specialist skills but works against a brief. If nobody in the business has the experience to write that brief and hold the agency accountable, the output tends to look busy without driving commercial results. According to Gartner's CMO Spend Survey, B2B marketing budgets have dropped from 11% to 6.4% of revenue since 2020. When the budget is smaller, wasted spend hurts more.

**A full-time senior hire** brings the strategic capability but comes with significant cost. According to the Alternatives/Marketing Institute of Ireland Salary Survey, a CMO in Ireland earns between €120,000 and €180,000 per year, with the Morgan McKinley 2025 Salary Guide putting the upper range as high as €300,000 for larger organisations. That's a serious commitment before you've even validated what works.

A fractional Chief Marketing Officer offers a middle path. Senior strategic capability on a flexible basis, scaled to what the business actually needs. This model is growing for a reason. It lets companies get the strategic layer right before making bigger, more permanent investments.

The compounding problem

What makes this decision so time-sensitive is that marketing is a compounding activity. The content published this month drives traffic next month and leads the month after. The positioning work done now shapes how every future prospect perceives the company. The measurement framework built today becomes the basis for every future investment decision.

When nobody is leading marketing, that compounding effect doesn't start. Six months of no marketing isn't just six months of missed leads. It's six months of content that wasn't created, authority that wasn't built, and positioning that wasn't established. All of that lost ground takes time and money to recover.

Getting it right matters more than getting it started

The temptation is to just do something. Run some ads, post on LinkedIn, hire someone, engage an agency. Activity feels like progress. But activity without strategy is just motion.

The companies that build effective marketing functions are the ones that invest in getting the foundation right first. The positioning, the customer understanding, the channel strategy, the measurement. Once that's in place, everything that follows is faster, cheaper, and more effective.

If marketing is becoming a conversation in your business, the most important thing you can do is make sure the right person is leading that conversation. Someone with the experience to make the right strategic decisions, and the accountability to deliver on them.
