Being the marketing lead in a lean team is nothing like being a CMO in a big one

One of the most common conversations I have with marketers moving from large organisations into startups or scaleups goes something like this. They are excited. They have real seniority for the first time. They have budget ownership, strategic influence, a seat at the leadership table. And within three months they are either thriving or quietly struggling in a way they did not expect.

The ones who struggle are almost always struggling for the same reason. They are trying to operate like a big-company marketing leader in an environment that does not work that way.

The title might be similar. The actual job is very different.

What a big-company marketing leader actually does

In a large organisation, a CMO or senior marketing leader (even a marketing manager) is largely directing other people's work. You set strategy. You manage agencies and internal teams. You present to the board or senior leadership. You make decisions about what gets prioritised and what gets deprioritised.

The actual making of things is done by other people. That is not a criticism, it is the job. And it requires real skills: stakeholder management, resource allocation, political navigation, and the ability to make good calls with incomplete information at scale.

But those skills are not the same ones you need in a lean team.

What the lean team marketing lead actually does

In a startup or scaleup with a small marketing function, you are the strategy and the execution. You are deciding what to prioritise and then doing at least some of it. You are writing the brief and producing the work. Sometimes on the same afternoon.

What catches experienced marketers out is the pace at which context shifts. In a big company you have time to think, time to consult, time to build consensus before anything moves. In a lean team you are making judgment calls constantly, with limited data, often ambiguity, and no approval chain to catch you if you get it wrong.

You also have much less cover. In a large organisation, a campaign that underperforms is one of many things happening. In a lean team, every piece of work you produce is visible, measurable, and directly connected to your reputation with the leadership team. There is nowhere to hide, which is clarifying in a way that can feel uncomfortable at first.

What transfers and what does not

Strategic thinking transfers. If you have spent years developing a real understanding of positioning, customer behaviour, and channel strategy, that comes with you.

Craft skills transfer. Copywriting, campaign thinking, performance analysis. If you have kept those sharp through your career, they are yours regardless of where you work.

What does not transfer as cleanly is the operating model. The instinct to brief someone else, to wait for the research to come back, to run things through a review process before committing. In a lean team, those instincts read as indecision and they slow everything down.

The other thing that takes time to recalibrate is comfort with imperfection. Big company marketing has a lot of quality control built in. Multiple review rounds. Brand guidelines enforced by whole teams. In a lean team, good enough and out the door is often the right call. Learning to make that judgment without it feeling wrong takes longer than most people expect, especially if they have spent years in environments where the expectation was always polish.

What actually makes someone good in this environment

The marketers who thrive in lean teams tend to share a few things. They are comfortable making decisions without full information. They can hold strategy and execution in their head at the same time without one crowding out the other. They are honest and fast about the gaps in what they can do themselves, and they find solutions rather than workarounds. And they have a very clear sense of what matters most, because the priority call is constant and you cannot do everything.

They also tend to have a real tolerance for ambiguity. In a big company the role is usually well defined. In a lean team you are often defining it as you go, and whoever you report to may not know exactly what they need from you either. You have to be okay with that.

If you are thinking about making the move

Be honest with yourself about which skills you are actually bringing versus which ones were made possible by the resources around you.

The strategic thinking is yours. The craft you have kept sharp is yours. The relationships and judgment you have built are yours.

The team of six who executed your campaigns, the agency producing your creative, the data team who built your dashboards, those belonged to the organisation. In a lean team you will need different solutions for all of it.

That is not a reason not to make the move. A lot of people do the best work of their career in lean team environments. There is something clarifying about being accountable for the whole thing, strategy through to execution, with no gap between the two.

Just go in knowing what you are actually signing up for.
