Private equity firms are rigorous about almost everything. They model scenarios, stress-test assumptions, and track portfolio performance with precision. And then, systematically, they underinvest in understanding the one thing that drives the revenue multiple at exit: the product, technology, and the organizations that deliver them.
This isn’t a critique. It’s a structural problem. PE firms are excellent at what they’ve been built to be excellent at, financial analysis, deal structuring, commercial diligence, management assessment. The product and technology organization is a different kind of problem. It requires a different lens.
Why the Financial Metrics Aren’t Enough
In a PE-backed SaaS company, the product is the asset. But the technology, engineering and product teams, infrastructure, and delivery operations determine whether that asset appreciates or decays.
Customer retention, expansion, pricing power, and the story you tell at exit all trace back to what the product delivers, how sound the technology underneath it is, and how well the organization behind both operates.
The problem is timing. The financial metrics tell you what happened last quarter. By the time they signal a problem in the product and engineering organization, the underlying causes have typically been compounding for six to eighteen months:
-
Customer satisfaction erodes before churn moves. You see the churn number in the quarterly review. You don’t see the support ticket trends, the feature request backlogs piling up, or the customer success conversations happening three months earlier.
-
Delivery capacity degrades before the roadmap slips. Teams accumulate technical debt, lose engineers, and struggle with an increasingly complex codebase, long before the quarterly roadmap review shows a pattern of delayed releases.
-
Technical debt accumulates before reliability fails. The architecture decisions made three years ago start showing up as incident rates, deployment anxiety, and developer productivity problems, which eventually show up as customer-facing reliability issues.
-
Cloud spend grows before anyone asks why. Infrastructure costs creep upward quarter over quarter, often unnoticed until they start materially compressing margins.
None of these are invisible. But you have to know what to look at, and you have to look at the right leading indicators, not just the financial outputs.
What Rigorous Technology Diligence Actually Covers
Most technology due diligence focuses on the obvious: Does the architecture scale? Is there significant technical debt? Are there security vulnerabilities?
Those are necessary questions. They’re not sufficient ones.
The most important questions in technology diligence are harder to answer because they require judgment, not just analysis:
Can the engineering organization execute the plan? The architecture might be sound, but if the team is understaffed, has critical single points of knowledge, or is demoralized from years of being treated as a cost center, the plan won’t be executed. This requires assessing the team, not just the technology.
Is the product delivering on retention and expansion? Revenue retention and net retention tell you part of the story. But understanding why customers renew or expand, and what product gaps are putting renewal at risk, requires deeper product analysis.
What does it actually cost to run this thing? Cloud spend, support costs, and delivery services often look very different up close than they do on a P&L. And they often have significant optimization opportunity that shows up as EBITDA improvement post-close.
What are the decisions that haven’t been made yet? Every company has a set of strategic technology decisions that are being avoided, a platform migration that’s been debated for two years, a product rationalization that everyone knows needs to happen but no one wants to own. These deferred decisions are often where the real post-close risk lives.
The Right Moment to Look
The PE firms that do technology diligence well tend to do two things differently:
First, they bring in someone who has been in the seat, not just studied it. The ability to read an engineering organization, to assess whether a roadmap is realistic, to identify the political dynamics that are making a product decision hard, this comes from having been accountable for the same problems, not from having read about them.
Second, they look at technology not just at acquisition, but throughout the hold period. A company that was in good technical shape at close can drift significantly over two or three years, especially through growth, M&A, or leadership changes. The board visibility that makes technology health legible on an ongoing basis, not just at diligence, is one of the highest-leverage investments a PE sponsor can make.
