That number does not shock most people who have held the role. The first 90 days set the trajectory. The first budget conversation either builds credibility or erodes it. And in most organisations, that conversation arrives long before a new leader has the evidence to have it on their own terms.
What follows is not a framework or a checklist. It is a description of what those first 90 days actually look like - and where the structural problems that derail new marketing and digital leaders tend to appear.
Most new marketing and digital leaders spend their first month listening. Meeting stakeholders. Reviewing analytics. Reading whatever strategy documents exist. Forming a view.
Isabelle Papoulias, CMO at BackBox, describes how she handled it:
"Get yourself invited to join the board meeting before you start. That was the single most invaluable thing for me because that was the business download right there."
The problem is that the picture emerging from that process is almost always incomplete - and often misleading. Research into how new leaders experience the onboarding period consistently shows that the digital estate they inherit is underperforming in ways the interview process did not reveal. Analytics have never been properly configured. Traction figures were overstated. Commitments were made to platforms or agencies that do not bear scrutiny once you are inside them.
This is not unusual and it is not a reflection on the previous incumbent. It is the nature of inheriting a complex digital estate from the outside. You only see what you are shown until you are inside it.
The second problem that emerges in this first phase is the absence of any credible external competitive context. The competitor benchmarks that exist, if any exist at all, tend to reflect the names that came up in the last board presentation - familiar peers that the organisation has always measured itself against. What they almost never include is an independent, externally produced view of where the organisation actually stands relative to the organisations that are genuinely setting the standard or taking market share.
Somewhere between weeks four and eight, the listening phase ends - whether you are ready or not. Decisions start being pushed toward you. Platform conversations begin. A rebuild has been in discussion for eighteen months and people are waiting to see what you think. The budget cycle is either approaching or already open.
This is where the first serious structural pressure arrives. Technology adoption in most marketing functions is outpacing organisational readiness. Platform decisions get made before a clear digital strategy exists to inform them. Rebuilds and migrations get scoped against what internal teams already know rather than against an evidenced view of what the business actually needs. Gartner's research shows that no marketing technology activity consistently scores above 5 on a 7-point performance scale - and the barriers are organisational, not technical. Budget, integration, bandwidth, capability. Committing to a rebuild before those barriers are understood does not resolve them. It makes them more expensive.
The pressure to act is real. A new leader who is seen to be moving is a leader building credibility. But as Nick Davies, co-founder of Pretty Pragmatic, writing in The Drum, puts it:
"Shooting from the hip and cracking under demands to 'just do it' is a short-sighted approach that can lead to a shortened tenure."
The productive tension in this phase is between acting fast enough to demonstrate momentum and acting carefully enough not to set the wrong trajectory. The leaders who navigate it well are the ones who can show movement - visible, evidence-based progress - without committing irreversibly to a direction they cannot yet fully justify.
At the same time, the clock is running. The average new marketing leader is expected to show meaningful impact within the first quarter. The pressure to contribute is not self-imposed. In many organisations, it is explicit from day one.
By month three, most new marketing and digital leaders are facing a version of the same situation. They have formed a clear view of what needs to change. They have identified the priorities. They may even have started building the case for investment. But when they test that case against the questions a board or a CFO will actually ask, it does not hold up the way they expected.
Marketing budget is treated as discretionary spend in most organisations. There is no operational dependency on it in the way there is on technology infrastructure or logistics. When budgets tighten - and over half of CMOs are now operating with budgets below 6% of company revenue - marketing is cut first. The CMO-CFO relationship is rated just 4.5 out of 7 for effectiveness when it comes to building a business case for marketing investment. Fewer than half of organisations report marketing and finance working together on growth decisions at all.
The investment case that gets budget released is not a strategy document. It is a financial argument, built in the language a board acts on, connecting digital investment to commercial return - revenue, customer acquisition, retention, brand authority. Fewer than 44% of chief marketing officers present revenue-oriented metrics to their leadership teams. The gap between what a new leader knows to be true and what they can prove in financial language is where most digital investment cases stall.
Building that case from internal evidence alone takes months. It requires data the organisation may not have configured properly, a competitive context it may not have produced, a platform direction it has not yet agreed, and an ROI framework that finance will accept. Most new leaders who try to build it internally produce something that reflects their own assumptions rather than something that will survive scrutiny from a team that was not part of building it.
And then they walk into the room.
The structural problems that derail new marketing and digital leaders in their first three months are not personal failures. They are predictable consequences of inheriting a complex digital estate without an independent baseline, without external competitive context, and without the financial framework to translate a strategic view into a capital case.
The leaders who navigate the first 90 days well share a common approach. They get an independent read of the digital estate before acting on what they have been told. They build competitive context from outside the organisation, not just from inside it. They separate the question of what needs to change from the question of how much it will cost and what it will return - and they answer the second question in the language their Board actually uses. And they do not commit capital to platform or rebuild decisions before they have a strategy that justifies them.
As Bernd Leger, CMO at Cornerstone OnDemand, puts it:
"You only have so much time yourself in those 90 days. Figure out where you can use external resources. For example, external vendors can do an audit to accelerate your assessment of your team, the processes, and the function."
The Digital Strategy Sprint is a fixed-scope engagement that produces a Board-ready digital investment case in six weeks. Five structured workstreams: a performance diagnostic, a named competitor benchmark, a platform direction statement, a digital ROI framework, and a prioritised digital vision and roadmap.
It is not a discovery engagement that leads to a development pitch. It is a paid, fixed-scope consultancy product with a single output: the external evidence and financial argument a new marketing or digital leader needs to walk into a board conversation with confidence.
When the findings are presented to your leadership team, we present them alongside you. Not on the end of a phone but in the room with you.
If a structured engagement is not the right move yet, the most useful immediate step is an understanding of where your digital estate stands.
Our Digital Optimisation Assessment takes less than ten minutes. It gives you a benchmarked view of your current digital performance across the dimensions that typically determine whether an investment case holds up under scrutiny. The results surface the gaps that are hardest to evidence internally and give you a foundation before any larger conversation begins.
The results are worth having regardless of what you decide to do next.
