In many organizations—particularly those backed by private equity—the spotlight naturally falls on the CFO. Capital strategy, investor relations, board communication, M&A activity, and long-range planning dominate the narrative of value creation. But behind every effective CFO is a role that quietly determines whether strategy becomes reality: the Controller.
The best CFOs will tell you this plainly—no matter how strong the strategy, the business does not scale, exit, or survive turbulence without an exceptional Controller.
Strategy Fails Without Operational Financial Excellence
- In PE-backed companies, timelines are compressed and tolerance for financial ambiguity is low. CFOs are expected to think at altitude:
- Managing lender and investor relationships
- Driving value creation initiatives
- Overseeing capital structure and liquidity
- Preparing the business for exit readiness
That level of responsibility is incompatible with day-to-day transactional oversight. The Controller becomes the operational backbone of the finance function—owning the accuracy, discipline, and cadence that allow the CFO to operate strategically rather than reactively.
A high-performing Controller ensures:
- Clean, timely, and reliable monthly closes
- GAAP compliance and audit readiness
- Strong internal controls
- Consistent forecasting inputs
- Confidence in the numbers at all times
Without this foundation, CFOs are forced back into the weeds—distracted from the very work investors hired them to do.

The Controller as the Force Multiplier
The Controller is not simply “senior accounting.” In the most successful organizations, the Controller functions as a force multiplier for the CFO.
When properly aligned, the Controller:
Anticipates issues before they reach the CFO
Translates strategic objectives into executable financial processes
Brings rigor to reporting while improving speed
Acts as the internal steward of financial truth
This dynamic allows the CFO to engage externally—while trusting that internally, the machine is running flawlessly.
In PE environments especially, this trust is invaluable. Investors expect fast answers, precise data, and zero surprises. A strong Controller makes that possible.
Why CFO-Controller Alignment Matters More Than Resume Strenght
One of the most common hiring mistakes companies make is prioritizing technical credentials over working style alignment.
A Controller must complement the CFO—not replicate them.
For example:
A visionary, externally focused CFO needs a detail-obsessed, execution-driven Controller
A process-oriented CFO may benefit from a Controller who thrives in ambiguity and change
A first-time CFO often needs a seasoned Controller who has “seen the movie before”
The right pairing creates leverage. The wrong pairing creates friction, duplication, and blind spots—often at the worst possible time.
Daily Value Creation Happens at the Controller Level
While CFOs drive the headline initiatives, Controllers create value every single day.
They do this by:
- Reducing close timelines
- Improving data quality for operational leaders
- Strengthening cash visibility
- Preventing control failures before they become material issues
- Enabling faster, better decision-making across the organization
In PE-backed businesses, where incremental EBITDA improvements matter, this daily discipline compounds quickly.
The Controller’s Role in Exit Readiness
Exit success is rarely determined in the final year—it’s the result of years of financial consistency.
Controllers play a critical role in:
- Establishing repeatable, defensible financial processes
- Maintaining audit-ready financials
- Supporting QoE processes with confidence
- Ensuring the story told externally matches the data internally
In many cases, the Controller is the difference between a smooth exit process and a painful, value-eroding one. For a deeper look at how exit readiness ties to CFO equity in private equity, see our related article.
Final Thought: Hire the Controller Like you Hire the CFO
If the CFO is the architect, the Controller is the builder.
Organizations—especially PE-backed ones—should approach Controller hiring with the same intentionality they apply to the CFO role. This means assessing not only technical competence, but leadership style, communication approach, and the ability to operate as a true partner.
The most successful CFOs don’t just have great Controllers.
They build their success because of them.
