Your first 90 days as a CMO: a 30/60/90 day operating sequence
A gate by gate 30/60/90 day sequence for a new CMO, with the outputs a founder should be able to point at on day ninety one.

Asked what their fractional CMO did in the first ninety days, most founders describe a process: discovery, immersion, interviews, and a strategy presentation in week ten. A CMO who wants to be kept, referred or promoted needs a better answer, which is a short list of things the founder can point at on day ninety one, produced in an order that makes each next thing possible. Each phase below ends at a gate, because companies move at different speeds and a gate passed in week three beats a milestone hit on schedule with nothing behind it.
The sequence assumes the company passed the checklist in the playbook “Is the company ready for you? A checklist to run before you accept a CMO role.” A company that failed it needs a different first quarter, and an honest CMO says so before signing.
Days 1 to 30. Find the truth and stop the bleeding
The first month has two outputs, and neither is a strategy.
The first is a single page that states where the money goes and what comes back: every channel, agency, tool and recurring spend, set against what the company can say about the customers each one produced. The page will have holes, and the holes are your first finding. A company that cannot say where its last fifty customers came from cannot support a plan, so you spend a week fixing attribution, cleaning the CRM and getting sales to tag deals properly. The work is unglamorous, and it is why the company hired somebody senior, since nobody junior has the authority to make sales tag deals.
The second is the stop list. A marketing function that has run without a leader collects spend nobody chose: the agency retainer nobody has briefed since last year, the paid social that runs because turning it off feels like giving up, and three tools doing one job. Stop at least three things in the first thirty days, and let the money saved fund the next sixty.
Alongside both, talk to customers: eight recent buyers and three who chose a competitor. You are listening for the positioning the market already holds, which is almost never the positioning on the website.
The gate at thirty days: a true page on spend and return, a stop list that has been acted on, and a short memo of what customers said. If any of the three is missing, the second month waits.
Days 31 to 60. Decide, then make the decisions visible
The second month is where the senior fee earns itself.
Positioning comes first: one sentence about who the company is for and why they choose it, written so the sales team can say it without wincing. It comes out of the customer conversations, it rewrites the website headline, the first slide of the sales deck and the brief to every agency, and it costs almost nothing to implement, which is why it so often gets skipped for work that looks bigger.
The channel plan follows: two channels to double down on, one to test, and a written reason for everything left off the list. Each channel gets a budget, an owner, a leading indicator and a date by which the indicator must move. Without those four things the plan is a wish.
Then the structure: who stays, who goes, and who is re-briefed against numbers. This is the month a fractional leader simplifies or fails, and the sixty day gate should leave the company with fewer moving parts than it had on day one, since a leader who adds approval steps to a structure that is already too complicated slows the company down.
Last comes the dashboard: five to eight numbers, reported weekly, that connect marketing activity to pipeline and pipeline to revenue. The founder reads it on Monday morning. The first version will be wrong, and the habit of looking is the deliverable.
The gate at sixty days: positioning in use by sales, a channel plan with budgets and dates, a simpler structure of agencies and people, and a weekly dashboard that has been read at least four times.
Days 61 to 90. Make it run when you are not in the room
The third month tests rhythm. A fractional leader works two or three days a week, so the company must run on the other days, and a full time CMO faces the same test on the day they go on leave.
Give the weekly marketing meeting a fixed agenda that starts with the dashboard and ends with decisions, kept to thirty minutes, with agencies presenting numbers and the founder attending the first four and then no longer needing to.
Brief the first hire. At the sixty day review you will usually find a gap you should not fill yourself, most often a hands on marketer who can run the two chosen channels. Writing the brief, running the search and sitting on the panel belong inside the ninety days, and a hire who starts in month four lets you move from doing to deciding.
Let the leading indicators come due. Some will have moved and some will not, and each one that has not gets a decision: more time with a stated reason, a change of approach, or a stop. A CMO who cannot say stop in month three will not say it in month nine.
Mention the exit. Some buyers ask a fractional CMO to lay the foundations for a permanent CMO, and the best engagements design the handover from the start. By day ninety you should be able to say what the company would need to look like to justify a full time head of marketing, and how far away that is.
The gate at ninety days, the one that matters: the founder can describe, without notes, what is different. The sales team says the same sentence about who the company is for. Money has moved from channels that did not work to channels that did. There is a weekly number, fewer agencies or better briefed ones, and a hire under way for the work you should not do. A date, however rough, exists for the conversation about the permanent hire.
What the sequence refuses to do
It refuses to open with a strategy presentation in week ten, because a deck with no deliverables behind it is what clients remember. It refuses to launch a brand refresh in the first quarter, since the positioning changes in month two and the logo changes only if it is costing sales. It refuses to let you do the execution: if you are building campaigns in month three, the structure decision in month two was wrong and the fee is paying for the wrong work. And it refuses to run past ninety days without a review that could end the engagement, held with the questions from the playbook “The 12 questions buyers ask a fractional CMO, and how to answer them” asked in the past tense, covering what you owned, what is different and what the numbers say. If the answers are thin, say so in month four rather than month twelve.
Day ninety one should be the easiest conversation of the engagement: here is what is different, and here is what comes next.
Practise this week
Choose a company you know and write its day thirty gate: the spend page with its holes marked, a stop list of three items, and the customers you would call first. If you can fill the stop list in an hour, you have the instincts for the first month. If you cannot, the missing information is your reading list.
