In private equity, every quarter counts. Each quarter must be devoted to driving valuation growth and executing the company’s value-creation plan. When a CMO leaves the PE-backed company or a merger is happening, the question is not only who will take the role next, but how the company keeps its momentum going forward. Under these circumstances, an Interim CMO becomes essential.
The search for a new CMO can take months. Meanwhile, marketing for the company can’t stop. Pipeline still needs to be built. Product and sales still need coordination. The board still expects progress toward company revenue goals. Every week without an experienced marketing leader can drain momentum, confidence, and revenue across the entire organization.
An Interim CMO can help prevent that drainage. The interim CMO can keep the company moving toward the revenue goals, maintain alignment between teams, and protect enterprise value while the right long-term leader is recruited and hired.
The Cost of Waiting to Replace the CMO
Private-equity timelines do not allow drift from corporate objectives. When marketing leadership sits vacant, three things usually happen.
Marketing priorities blur:
The marketing team stays busy but can often lose sight of what drives revenue for the organization and end up focusing too much on vanity metrics.
Organizational departments pull apart:
Sales, Product, and Customer Success stop hearing a clear marketing point of view, which can cause siloing, which is bad for this to happen, but it’s even worse in a PE-backed company with no seasoned marketing leadership.
Marketing Project and Competitive Momentum fades:
Projects stay 90 percent finished, which in practice means zero progress in the market, and that can allow competition extra time to gain ground or take the lead by even more of a margin.
By the time the negative results from a lack of strong marketing leadership appear in the dashboard, the damage has already spread through the pipeline and possibly the whole organization.
An experienced Interim CMO helps prevent the downward slide for the organization.
They step in quickly, make decisions, keep the team aligned, and maintain the trust of the C-Suite and the board.
What an Interim CMO Actually Does
An experienced interim CMO does not sit on the sidelines. They join the executive team, attend forecast reviews, and take ownership of results.
When I take an interim role, I treat it as if I were your CMO, because for that period, I am.
I work directly with the CEO, the CFO, and sales leadership to keep marketing productive and connected to the rest of the company.
At FinThrive, for example, I served as Interim CMO for six months during a transition. When the new CMO came on board, I stayed for another fourteen months as her coach and advisor. The company never lost pace.
That is what being an interim CMO is about: keeping the organization healthy while new leadership takes shape.
Working Fast Without Rushing
Speed in this context means cutting idle time, not cutting corners. It’s important to bring an experienced interim CMO into the organization, because it’s integral that they have been through these situations before, so they can get things done efficiently in a compressed timeline.
My first six weeks in a company usually look like this:
- Weeks 1–2:
Interview everyone in the marketing department and the C-suite, which allows to me find any gaps in the marketing that need fixed, and the successes to know what is going right and if need be what needs ramped up.
I also review demand generation, current pipeline, team structure, and budget with the CFO.
- Weeks 3–4:
Identify quick wins that restore confidence, such as finishing a stalled campaign or unifying the marketing messaging before a launch.
- Weeks 5–6:
Deliver visible results, establish a weekly cadence, and prepare updates for the board.
This approach keeps work measurable and predictable. It also gives the CEO and CFO reliable numbers while the search for a permanent CMO continues.
Protecting Enterprise Value
When the CMO seat is empty, valuation risk for the organization grows quietly.
Marketing influences almost every lever that supports exit value, from pipeline velocity to customer retention.
An Interim CMO protects that value by:
- Keeping revenue programs running during leadership changes.
- Maintaining investor confidence through consistent updates.
- Coordinating with finance to keep forecasts accurate.
- Helping product, sales, and customer teams stay connected during integration or carve-out periods.
In a PE environment, this kind of steadiness is not optional. It supports the growth story investors expect to see within the company.
Simple Economics
CFOs appreciate the Interim CMO model because it is straightforward.
There is no severance, benefits, or equity dilution. The cost is a quarterly retainer with clear expectations. Results appear within weeks, not quarters.
I keep my arrangements simple. A defined scope, clear goals, and predictable cost. The company maintains flexibility while staying productive.
What to Look For in an Interim CMO
The right person for this role brings more than marketing skills. They bring perspective. Look for someone who has:
- Served as a CMO before and understands executive pressure.
- Worked across sales, finance, and operations.
- Earned the trust of CFOs by speaking in business terms.
- Presented to boards and investors with confidence and precision.
- A record of leaving organizations stronger than when they arrived.

Lessons Learned
After leading several Interim CMO engagements, a few consistent patterns stand out.
Every company in transition needs two things at once: stability and understanding. You can’t just enforce new processes and expect results. You have to understand what’s really happening inside the organization, what’s working, what’s broken, and what people are worried about losing. Only then can you rebuild confidence and move forward.
An Interim CMO’s job isn’t to overhaul everything; it’s to steady the ship, create focus, and remind the marketing team that progress is still possible. The right blend of structure, transparency, and empathy can turn uncertainty into momentum again for the organization.
Questions PE Firms Often Ask
How long should an Interim CMO stay?
Most interim CMO engagements run six to nine months, long enough to steady operations and guide the search.
Can an Interim CMO help before a deal closes?
Yes. Early involvement keeps brand and customer communication consistent across organizational transactions.
Will they fit our operating rhythm?
A good interim marketing leader will. I work within 100-day plans, attend weekly reviews, and link marketing results directly to financial outcomes.
Can the interim CMO mentor the next CMO?
That is often part of the work. When requested to do so, I frequently stay on to coach the new hire so there is no loss of momentum.
How fast can an interim CMO start?
Usually within a few weeks. The goal is to keep the business moving, not to create another delay.
Who I Am and Why I Do This
I have spent decades working with CMOs, boards, and executive teams. I am Alan Gonsenhauser, CEO of Demand Revenue LLC, a 12x CMO and three-time general manager with experience in marketing, sales, finance, and operations.
I serve as a CMO coach and mentor, an Interim and Fractional CMO, and a Go To Market Partner and Advisor. The principles behind the Go-To-Market Operating System have shaped my work for years.
At Forrester, formerly SiriusDecisions, and afterward, I have mentored more than 150 marketing leaders, helping them become reliable partners to their CEOs and boards.
Since 2021, through Demand Revenue, I have worked with more than ten private-equity portfolio companies to strengthen infrastructure, improve customer growth, and create consistency across departments.
I have learned that most companies do not struggle because of weak ideas or lack of effort.
They struggle when teams lose sight of one another.
The left hand does not know what the right hand is doing, and by the time they realize it, the cost has already been paid in wasted resources or missed opportunity.
That belief is what led me to join GTM Partners. Their models for uniting sales, marketing, product, and customer teams fit perfectly with the work I already do. I have seen the numbers firsthand: organizations that stay coordinated grow faster and are more profitable.
At its core, growth depends on connection. Every department has to move in the same direction.
When Standing Still Costs More Than Moving
In private equity, standing still is not neutral; it erodes enterprise value.
An Interim CMO does more than fill a seat. They protect momentum, hold teams together, and keep the business moving forward until the right leader is in place.
If your portfolio company is between CMOs or entering a transition, do not let months of uncertainty undo years of work.

Let’s talk about how a stronger go-to-market structure can help your organization grow with fewer setbacks.
Sometimes the smartest move is not racing ahead; it is making sure you never lose stride during the race.
