The contract between marketing and finance has been rewritten. Most marketing teams have not read the new version. After two efficiency cycles since 2022, the CFO is no longer the gatekeeper of marketing budget. Finance now helps design the marketing model itself: the channels, the agencies, the data, the brand investment. One model asks the CFO for budget. The other builds the system with them.

The facts moved faster than the playbooks. Average CMO tenure in major enterprises now runs between eighteen and twenty-four months. Average CFO tenure runs closer to five years. In many boardrooms the CFO is the longest-serving senior voice on marketing strategy in the room. They remember which spend rebuilt the brand and which cuts cost demand. That memory is part of the marketing conversation now, whether the function engages with it or not.

Six senior practitioners describe what the new contract looks like in practice. Kimberly Hairston-Hicks of Gold Bond on running brand as a business. Andrew McCormick, formerly of Dentsu X, on the move from cost centre to investment. Maor Sadra of Incrmntal on the measurement the CFO actually wants. Edwin Wong of Uber Advertising on the brand case under efficiency pressure. Andrew Bialecki of Klaviyo on public-company discipline. Jem Lloyd-Williams of WPP Media on growth as the only frame that matters.

Running a brand means running a business, not just a campaign

Kimberly Hairston-Hicks runs marketing at Gold Bond, with general-management experience behind her. She is direct about what the new contract requires. The CMO who treats marketing as the creative department and the CFO as the budget approver is working to a contract two cycles out of date.

“CMOs need to always have that as a guide and not just think of big ideas. They have to get very close to their finance team. They have to run the business, their brand as a business and not just as consumer facing.”

The CMO is now judged on the same outcomes as any general manager. The two roles are converging. A brand is a business unit, and marketing should be run with the same financial accountability as product or sales. The CFO is the partner who keeps it honest.

That moves the conversation past the annual budget request. Instead of marketing asking for resources and finance asking for returns, the two design the operating model together: how the function is structured, what it measures, which channels carry the brand into the next decade.

The Strategic Reframe

Bringing finance in after the planning is done is the wrong move. The marketing teams that work best bring the CFO into operating-model design at the start of the cycle.

Moving marketing from cost centre to investment line

What marketing produces decides how finance files it. Produce outputs, and it gets booked as a cost centre. Produce outcomes the CFO can see, and it becomes an investment line. Andrew McCormick, formerly Chief Growth Officer at Dentsu X, has watched that line get drawn from both sides.

“All media and all agency fees should be an investment, and you know what you're getting back. It's no longer good enough to just be paid for outputs. It needs to be outcomes.”

The difference matters to the CFO. A cost centre is something to manage down. An investment line is something to partner on, the way the CFO already treats sales, product and customer success.

The agency model shows where this is heading. The best agencies now propose payment tied to growth delivered, not hours billed. The same logic is arriving inside marketing teams: headcount, infrastructure and channels judged on what they return, not the activity they generate.

Incrementality has replaced attribution as the core question

The CFO is no longer asking which channel got credit for the sale. The question is whether the sale would have happened without the spend. Maor Sadra, CEO and Co-Founder of Incrmntal, built a measurement business on that one question.

“The job of every marketer is to create value. Incrementality needs to be the default. I'm spending money on ads, I should be getting something that is incremental, that I wouldn't just get if it wasn't for my ad spend.”

Maor Sadra · CEO, Incrmntal

Attribution distributes credit among channels for sales that have already happened. Incrementality measures the sales that would not have happened without the spend. The first answers a marketing question. The second answers a finance question. The CFO wants the second answer, and most dashboards still produce the first.

Freenow, the European mobility company, ran on conventional last-click attribution. Incrmntal rebuilt the media mix around incremental value instead. Same conversions, less spend. That is not a marketing optimisation. It is a balance-sheet improvement, and the kind of result that turns the CFO conversation from trust into partnership.

Executive Insight

Attribution belongs in the marketing team. Incrementality belongs in the CFO read. Move incrementality into the financial review and the partnership changes. Keep showing the CFO attributed channel mix, and you are still asking them to take marketing on trust.

Balancing brand building with short-term efficiency

The last decade of efficiency pressure produced a liability that never showed up on a quarterly report: brand erosion. Cutting the long-term work looked free for two or three quarters, then arrived as weaker demand and higher acquisition cost. Edwin Wong, Global Head of Measurement at Uber Advertising, has measured both sides of that trade.

“Over the last ten years, the economy and pressures on CMOs to deliver more for less have meant something has been sacrificed, which is the long-term activity. Brand development. People want demand, but they also have to invest in brand.”

The number the CFO usually gets is return on ad spend, built on last-click attribution. ROAS rewards harvesting demand that already exists. It says nothing about the brand health that creates demand in the first place. Optimise for it alone and the function looks efficient for a quarter or two, then hits the drag of brand erosion the CFO remembers from the last cycle.

The indicators worth promoting into the CFO read are the ones that show long-horizon health: acquisition cost trended against lifetime value, brand-driven demand against performance-driven demand over twenty-four months, marketing-sourced pipeline as a share of the total, payback period by channel. None of these are new. The only question is which ones the CFO actually sees in the quarterly review.

The finance team holds the institutional memory

Most boards have not absorbed what longer CFO tenure means. The CFO holds the longest continuous view of the brand's commercial strategy in the room. Not just the budget history: the memory of which investments built customer equity, and which cuts showed up two or three quarters later as weaker demand and a brand working harder for the same return. The current CMO cannot get that by reading the file.

Andrew Bialecki, Co-Founder and Co-CEO of Klaviyo, brings the public-company view. Klaviyo bootstrapped to IPO with a different discipline from the venture-backed software firms around it, and Bialecki names the reference point.

“We looked back at the Oracles, the Apples, the Microsofts, and all of those companies were profitable when they went public. That wasn't a norm in the 2010s and 2020s, but we looked at that and said, they were able to build a real business. Why can't we do the same thing.”

Andrew Bialecki · Co-Founder & Co-CEO, Klaviyo

The point holds well before any IPO. A business that keeps financial discipline through scale, brand investment included, is one the CFO can defend through the next downturn. Eighteen months is the CMO's horizon. The business is the CFO's. Working to the longer clock means treating the CFO as the partner who holds it.

Three steps before the next planning cycle

Three implications sit at board level. None requires rebuilding the function. Each requires bringing the CFO in earlier.

First, modernise the financial reporting. Put incrementality, lifetime-value movement, payback period and contribution margin into the CFO read alongside the marketing dashboard. The data already exists. Elevating it is the marketing leader's call to make, and making it before being asked is the work of the partnership.

Second, open the operating model to the CFO. Quarterly reviews should cover the model, not just the budget: channel architecture, agency model, in-house versus outsourced, measurement infrastructure, the brand line. These are operating decisions with multi-year consequences, and the CFO has a seat at the table for each.

Third, frame brand as capital allocation. Brand loses every budget argument it enters as a communications line, because communications budgets are cut first when the quarter tightens. It wins as capital allocation: an asset that compounds, depreciates when starved, and carries a cost of deferral the CFO can model. The vocabulary is already on the CFO's desk.

Every argument here runs on one fault line: the gap between the horizon marketing is measured on and the horizon the business lives on. Jem Lloyd-Williams, President of WPP Media, reduces the work to a single question: where does the growth come from. The honest answer rarely fits inside one planning cycle. Brand compounds over years. Erosion shows up quarters after the cut. Tenure turns over before the bill arrives. The CFO is the one seat already paid to hold the long horizon. Marketing has spent a decade treating it as an obstacle rather than the ally it always was.

The question every CMO should bring to the next planning cycle

"If the CFO is now the longest-serving senior voice on marketing strategy in our company, what conversation should we be having with them this quarter that we're not?"
