Fractional head of growth (fractional CMO) for B2B SaaS
Leadership close enough to make a difference.
A fractional head of growth is a senior, part-time growth leader who works inside your business on a monthly retainer. For founders, CEOs and CROs of B2B tech and SaaS companies, it connects strategy with day-to-day decisions, so marketing and sales work as one engine without a full-time executive hire.
Is this you?
01 / Recognise this?
Growth still runs through the founder.
Commercial decisions wait for you. Marketing and sales slow down whenever your attention is needed elsewhere.
Who owns growth when you are not in the room?
02 / Recognise this?
Plenty of activity. No clear priorities.
Campaigns, tools and requests fill the week, but priorities shift and nobody can say which work actually moves pipeline.
Which three things should your team stop doing?
03 / Recognise this?
Not ready for a full-time hire.
You need senior growth leadership now, but a permanent executive is a big commitment before the strategy and the team are clear.
What would a full-time CMO actually need to own?
What you get
- ↗ Growth leadership and executive sparring for founders and the leadership team
- ↗ A cross-functional growth roadmap that marketing, sales and product agree on
- ↗ One shared definition of your best-fit customer and a qualified lead
- ↗ Clear ownership across marketing, sales and operations
- ↗ An operating cadence and performance review the team keeps running

What a fractional head of growth does
A fractional head of growth sits close to the founders and the commercial team. The role connects strategy with the decisions your team makes every week: which accounts to focus on, which campaigns to run, which tools to keep and what to stop. It challenges assumptions, keeps execution focused on the priorities that matter and makes sure marketing, sales and product pull in the same direction.
This is leadership, not a consultancy report. The work happens inside your business, with your people, in your operating rhythm.
When it fits, and when it does not
It fits when you need senior growth leadership without a full-time appointment: the founder is still the de facto head of marketing, the team is capable but lacks direction, or you want the strategy right before you hire a permanent leader.
It is not the right fit when you need a full-time executive to run a large marketing organisation every day, or when the problem is a single, clearly defined project. In that case a GTM strategy sprint or a focused build-out is usually the better start.
Fractional head of growth, fractional CMO or interim CMO?
The three are often used interchangeably, but they solve different problems. An interim CMO fills a full-time vacancy temporarily. A fractional CMO owns the whole marketing function on a part-time basis. A fractional head of growth is narrower and more hands-on, focused on pipeline, demand generation and revenue.

Frequently asked questions
What is the difference between a fractional head of growth and a fractional CMO?
A fractional CMO is a part-time executive who owns the whole marketing function. A fractional head of growth is narrower and more hands-on: pipeline, demand generation and revenue outcomes. Many B2B scale-ups asking for a fractional CMO need the second. Read the full comparison.
How is a fractional head of growth priced?
Monthly retainer, scoped after the first call. There is no fixed package: the scope follows your situation and the work that matters.
How many days a week, and for how long?
1 to 3 days a week, depending on stage and scope. A typical engagement runs 6 to 12 months, with a 3-month minimum and then monthly with one month's notice.
How does this work with my existing team?
The aim is to strengthen your team, not replace it. I work alongside your people to connect the decisions, delivery and day-to-day operating rhythm.
Why not hire a full-time CMO or use an agency?
A full-time hire makes sense once the strategy, the team and the role are clear. An agency delivers campaigns. A fractional head of growth sets the direction, owns the commercial priorities and keeps the work, including agency work, focused on pipeline.
What do you need from us?
An executive sponsor, usually the CEO or founder; access to your CRM, marketing automation and analytics; and a fixed weekly slot with the leadership team.
