Speaking Topic: Private Equity & M&A Technical Diligence
Diligence as a mirror, not a formality: if it does not stress-test the system, it is ceremonial legal reassurance.
Diligence as a mirror: if technical diligence does not stress-test database query execution under synthetic peak load, audit the deployment rollback ratio, and measure key-person dependency across tribal runbooks, it is not diligence. It is ceremonial legal reassurance, and the acquirer finds out the difference about six months post-close.
I talk through why diligence is broken and, frankly, blind in most PE and M&A processes today: the team doing the audit is often reading the same architecture documentation the target company wrote about itself, with no adversarial pressure applied anywhere in the process.
The fix is not more documentation review. It is treating the target's production system the way a penetration tester treats a network: find where it actually breaks, not where the diagram says it should hold.
Key Takeaways
- 01Diligence that only reviews documentation is reassurance, not risk discovery.
- 02Key-person and tribal-knowledge dependency should be measured, not assumed away.
- 03Treating the target system adversarially, like a penetration test, surfaces real risk.
Frequently Asked
Why does standard M&A technical diligence miss real risk?
It typically reviews documentation the target company wrote about itself, without adversarial stress-testing, so systemic risk surfaces only after the deal closes.
From the Q&A
“Why would a seller's own engineering team not catch these issues first?”
They are often too close to the system to see tribal-knowledge dependency as a risk; it feels like normal operating practice from the inside.
“Does this kind of diligence usually kill deals?”
Rarely outright. More often it gets priced into deal terms or sequenced into a 100-day remediation plan rather than becoming a walk-away issue.
