A deal model is a long argument told in rows and columns. Most of the rows are checkable. Revenue last year happened. Gross margin happened. Then there is one number that has not happened yet, it sits near the top, and everything below it is downstream.
Quality of Growth is a pre-acquisition assessment of how durable, efficient, repeatable, controllable, scalable and transferable a company's growth really is. It reconciles historical growth, the current operating engine, and the growth assumed in the deal model.
The underwriting question it answers is narrow and specific: can this company produce the growth in the deal model, in the required time, at acceptable cost, with the team and systems it actually has?
Almost every diligence workstream touches that growth number. Financial diligence tests whether the earnings underneath it are real, then stops at the present. Commercial diligence tests whether the market is large enough, then stops at the company's front door. Operational diligence examines whichever functions the scope happened to cover. The model itself is not diligence at all. It is arithmetic performed on other people's conclusions. Often, no single workstream owns the reconciliation.
That was survivable while growth did not have to carry very much. It no longer is.
The growth hurdle doubled.
A 2015 buyout could clear a 2.5× gross return on roughly five percent annual EBITDA growth. A comparable 2025 structure needs eleven to thirteen. Bain named the shift: “12 is the new 5.” We rebuilt the arithmetic.
Three of those inputs are visible at entry: the multiple paid, the leverage raised, and the cost of that debt. The exit multiple is not observable. It is an underwriting choice. Once those four and the cash-conversion assumption are fixed, the required EBITDA growth is arithmetic. The judgment sits in the assumptions, not the calculation.
Two of the three return levers are now less dependable
Multiple expansion requires selling at a richer multiple than the one paid. With entry multiples near record levels, that is harder to underwrite responsibly. Deleveraging still matters, but less debt at entry and higher interest expense reduce what it contributes.
Most of the industry's return came from two levers that are now less dependable and more expensive. That does not make them unavailable. It makes operating performance less optional.
And growth is exactly what is failing.
No single audited statistic exists for deals that miss the case they were underwritten on. What exists is a consistent pattern across independent surveys and one deal-level study.
That last figure is the one that matters for diligence. If value creation plans failed mainly because of pandemics, wars and rate shocks, there would be nothing to underwrite; bad luck is not diligenceable. Fewer than one in five of those companies fell to events that were genuinely hard to foresee.
Simon-Kucher reaches the same place from the other direction: 67 percent of value creation initiative failures come from controllable causes, led by poor implementation and an unrealistic business case. An unrealistic business case is not bad luck. If it existed at signing, it is an underwriting error.

The blind spot is not a missing workstream. It is the space between them.
| Workstream | The question it answers | Where it stops |
|---|---|---|
| Financial (QofE) | Are the earnings we are buying real? | At the present. It validates history, not capability. |
| Commercial | Is the market attractive and demand real? | At the company's front door. Opportunity is not execution. |
| Operational | How capable are the functions we chose to examine? | At the edge of scope. Findings need not reconcile to the model. |
| The deal model | What growth must occur for the return case to work? | It is arithmetic on other people's conclusions, not evidence. |
| Quality of Growth | Can this operating system produce that growth, at acceptable cost, in the time available? | It reconciles evidence, capability, cost and time into one verdict. |
Accenture surveyed 251 senior private equity professionals at firms managing at least $5 billion. 83 percent said their current diligence approach has substantial room for improvement, and 40 percent named the discovery of unexpected capability gaps as a top challenge. None of this is a failure of effort. It is a failure of assignment.
Everyone touches the growth number.
Too often, nobody owns the reconciliation.
Fast is a speed. Quality is what survives contact with reality.
A company can grow quickly while the economics deteriorate, the system depends on heroics, or the capability disappears when the founder leaves. High-quality growth has six characteristics, assessed separately rather than averaged into a score.
Durable
Revenue persists because customers keep receiving value.
Efficient
Growth produces attractive contribution economics and cash.
Repeatable
Results come from a defined mechanism, not exceptional events.
Controllable
Management can move the drivers and read leading indicators.
Scalable
Volume can increase without disproportionate cost or complexity.
Transferable
The engine survives beyond a founder, seller, channel or relationship.
Percentages are where accountability goes to hide
A material growth lever should be translated into an equation. The equation does not prove the forecast. It makes the assumptions visible enough to test. Suppose the plan requires $12 million of incremental new-logo revenue. At a $200,000 average first-year value with 75 percent realizing in-year, that is 80 wins. At a 25 percent win rate, 320 qualified opportunities. At 40 opportunities created per productive seller per year, eight fully productive sellers.
The question changes immediately. It is no longer “can the market support $12 million?” It is “can this company recruit, ramp, enable, manage and feed eight productive sellers early enough for the revenue to land inside the hold?”
Evidence gets a ladder, and a rule
Assertion, anecdote, point-in-time, longitudinal, triangulated. Each level carries a permitted use. No material upside enters the supported case on the strength of assertion or anecdote alone. A plausible but unproven lever is not rejected. It belongs behind conditions, or in upside, until the evidence changes.
The Growth Underwriting Bridge
One picture, reconciling the growth rate management reported with the growth rate the deal model requires, and showing exactly where the difference has to come from.
Read left to right, the bridge answers four questions in sequence. What did the reported growth actually consist of? What survives normalization? How much does today's engine support without heroics? And how large is the distance between that and the number in the model?
The final bar is the only one that matters commercially. It is not a criticism of the thesis. It is the part of the thesis that has to be funded, sequenced and proven rather than assumed. A score compresses judgment into a number nobody can argue with. A bridge exposes every step, so an investment committee can disagree with one line without discarding the analysis.
The plan looked complete because the arithmetic nearly worked.
Project Atlas is an illustrative composite: a $72 million regional technical-services platform, five acquisitions deep, growing 15 percent a year, with a deal model underwriting 12.5 percent for five years. Four points of that growth came from acquisitions, two from catch-up pricing, one from project timing. The sustainable organic baseline was 8 percent.
Six growth levers were identified, summing to $18.9 million of year-5 incremental revenue. The distance between the current engine and the underwritten case was $19.0 million. Side by side, the plan appears to close the gap almost exactly. That coincidence is the trap.
The levers overlapped. Price affected volume. Cross-sell and new-logo growth competed for the same enablement and delivery capacity. New-market entry needed senior sellers already assumed in the core build. After evidence, timing, overlap and the binding constraint, $7.3 million survived into the conditional case.
| Case | CAGR | Year-5 revenue | Interpretation |
|---|---|---|---|
| Deal model | 12.5% | $129.7M | Requires nearly all material levers to land on time. |
| Conditional case | 10.4% | $118.1M | Funded and sequenced, behind named evidence gates. |
| Supported case | 9.0% | $110.8M | What the current system plus evidenced improvements supports. |
| Downside case | 7.0% | $101.0M | Capacity and new-logo constraints persist. |
Illustrative sensitivities, not a valuation opinion. Compounding from $72M at entry over a five-year hold.
The $11.7 million gap between the deal model and the conditional case is not a footnote. At an illustrative 30 percent incremental EBITDA margin and an 11.0× exit multiple, it carries $38.5 million of enterprise-value sensitivity on a business entering at $72 million of revenue.
The verdict was Conditional. The bridge did not say 12.5 percent was impossible. It said the investor had not yet earned the right to treat it as the base case.
A serious category earns trust by explaining where it ends.
Quality of Growth is a synthesis and a decision system. It should not be marketed as predictive science before a body of engagement evidence exists. The published paper states plainly what the evidence does not yet support: that funds routinely ignore growth, that no existing adviser performs adjacent quality-of-revenue or commercial diligence, that the six qualities predict investment returns, or that a universal benchmark applies across every business model.
Day One Growth did not invent the observation that revenue deserves its own diligence. Blue Ridge Partners has published on Quality of Revenue since January 2025. Termina markets an automated Quality of Growth scan. Craig Group, Coppett Hill and SBI Growth sell go-to-market diligence. Several capable firms arrived at this problem independently, which is the best available evidence that it is real. What we think is still missing is not the observation. It is the reconciliation.
Independence safeguards
The assessment fee is fixed regardless of verdict. The growth opinion is finalized before any execution scope is discussed. The sponsor owns the bridge, the model and the 100-day plan, and may hand them to any operator. Execution is separately scoped and never presumed.
Quality of Growth, answered directly.
What is Quality of Growth (QofG) diligence?
Quality of Growth is a pre-acquisition assessment of how durable, efficient, repeatable, controllable, scalable and transferable a company's growth really is. It reconciles historical growth, the current operating engine, and the growth assumed in the deal model, then states what the investor should underwrite. Quality of Earnings validates the earnings you are buying. Quality of Growth validates the growth you are underwriting.
How is it different from Quality of Earnings?
Quality of Earnings looks backward and validates whether reported historical earnings are real and sustainable. Quality of Growth looks forward and tests whether the specific operating system in front of you can produce the growth rate in the deal model, at acceptable cost, in the time available. QofE adjusts EBITDA. QofG adjusts belief.
How is it different from commercial due diligence?
Commercial due diligence tests whether the market is attractive and customer demand is real. It stops at the company's front door. Quality of Growth tests whether this company can convert that opportunity into revenue with the people, systems and capacity it actually has, and prices the capability gap in dollars and months.
What is the Growth Underwriting Bridge?
A single reconciliation from reported historical growth to the growth rate the deal model requires. It removes acquired revenue, catch-up pricing and one-time events to reach a sustainable organic baseline, adds the growth the current engine supports on evidence, and isolates the remaining execution gap that depends on capabilities that do not yet exist. Attached to that gap are the two figures deal models usually omit: what the capability build costs, and how long before revenue responds.
When does a deal warrant a Quality of Growth assessment?
When underwritten growth exceeds normalized historical growth by more than a few points. When reported growth includes acquisitions and organic performance has not been isolated. When the thesis depends on cross-sell, pricing, a new channel, seller hiring or geographic expansion. When commercial relationships concentrate in the founder or a few people. When attribution is weak or CRM is fragmented. When delivery capacity may bind before demand does. Or when the deal model contains no capability investment to produce the growth it assumes.
What does a completed assessment produce?
Three things. A Growth Underwriting Bridge the investment committee can debate line by line. A set of conditions management can own, each with an investment, owner, milestone, leading indicator and kill criterion. And a first 100-day proof plan that carries the same operating equations from diligence into the board cadence. A QofG has succeeded only if it changes or validates the price paid, the growth assumption underwritten, the post-close capital plan, or the first hundred days.
We will pressure-test the growth case before you price belief as fact.
Start with a 30-minute scoping conversation around the deal model, available evidence, and the growth questions most sensitive to enterprise value. No quiz. No generic score. If the fit is real, the assessment is fixed-scope, fixed-fee, and independent of any execution mandate.
