How to engage marketing leadership for different stages of growth

One of the most consequential decisions an early-stage business will make is the appointment of its senior marketing leader. The risk rarely lies in hiring the wrong person in isolation, but from appointing a profile misaligned to the company’s stage of development.


For founders approaching their first strategic marketing hire, the question is not “Do we need a CMO?” but “What capability does this stage of growth demand?” The answer evolves as the business scales.


In this article, Search Partner from 3Search Executive, Harrison Knowles, breaks down the different marketing leadership you should look to engage as you grow.



Seed stage: proving demand

At seed stage, the business is validating product-market fit and identifying viable acquisition channels. The objective is not to build a marketing function, but to build evidence.


Typical profile:


  • Headcount: 5-20

  • ARR: Pre-revenue to early traction

  • Funding: Pre-seed or Seed

  • Primary objective: Channel validation and repeatable acquisition


The appropriate hire is typically a Head of Growth with 5-8 years’ experience, reporting to the Founder or CEO.


This individual must be hands-on, performance-led and comfortable operating without infrastructure. They test channels, refine messaging and establish early CAC benchmarks. Success is measured by repeatability, not brand sophistication.


A common error at this stage is appointing a senior strategic leader removed from execution. Early-stage companies require operators who can personally drive experimentation. Hiring a future CMO too early often creates cost without commercial leverage.



Series A: introducing predictability

Following a successful Series A raise, expectations shift. Investors demand visibility, efficiency and control, meaning that marketing must move beyond experimentation and begin to demonstrate predictable growth.


Typical profile:


  • Headcount: 20-50

  • ARR: £1-5m

  • Primary objective: Building a predictable pipeline


Here, a Head of Growth or Head of Marketing with 7-10 years’ experience is appropriate. This leader retains operational depth but introduces structure: attribution models, funnel visibility and closer alignment with sales. They build the foundations of a scalable go-to-market model.


Be cautious of hiring someone shaped exclusively within mature organisations. Scaling businesses need leaders who have built systems from the ground up, not inherited them. At this stage, you require a builder of infrastructure.



Series A/B: scaling with efficiency

As the organisation approaches or enters Series B, marketing evolves into a core commercial driver. The remit expands from validating and structuring growth to scaling it efficiently.


Typical profile:


  • Headcount: 50–120

  • ARR: £5–15m

  • Primary objective: Scaling channels and building a profitable revenue engine


A Director of Growth or VP Growth with 10–14 years’ experience becomes relevant. This leader transitions from builder to orchestrator, overseeing multiple channels and a growing team. They balance experimentation with efficiency and ensure marketing investment translates directly into revenue.


One of the most sensitive transitions occurs here. Businesses often retain highly capable Seed-stage operators beyond the point of optimal fit. The skillset required to validate channels is not always the same as that required to scale them. Recognising when the business has outgrown its initial leader is difficult, but necessary.



Series B: marketing as an enterprise function

By Series B, marketing is no longer simply a growth lever; it becomes a strategic operating system across product, sales and customer functions.


Typical profile:


  • Headcount: 120-300+

  • ARR: £15-50m+

  • Primary objective: Market expansion and operational maturity


This stage demands a VP Marketing capable of progressing to CMO, typically with 12-18+ years’ experience and board-level exposure. The remit extends beyond channels into category positioning, expansion strategy, organisational design and disciplined budget ownership. Marketing becomes an enterprise-level function.


A frequent mistake is promoting the strongest channel expert into a CMO role without assessing their broader organisational design and stakeholder management capabilities.



Our perspective

Funding stage alone does not determine marketing maturity. Some Series B businesses operate with Series A foundations; some Series A companies face later-stage investor expectations.


The starting point is diagnosis. You should define:


  • The commercial outcomes required over the next 24-36 months

  • The structural capability gaps within marketing

  • Whether the current leader can scale with the business

  • When a CMO-level appointment becomes necessary

  • How marketing must integrate with other functions


The objective is not to hire seniority for its own sake. It is to appoint capability aligned to stage, ambition and capital structure. Learn more about leadership for different growth stages here.
