The Due Diligence Guide for Private Equity
What is actually built, what breaks after close, and what it costs — technical, commercial, and GTM due diligence before the model is signed.
Diligence is where a deal is de-risked, or a bad one is caught in time. This guide collects the operator’s view of due diligence for private equity: what to examine across technology, commercial, and go-to-market, and the questions a financial model alone will never surface.
It is written from the buy side of the table, by an operator who has read the code, tested the pipeline, and lived with what a shallow diligence missed.
Why diligence is value protection, not a checkbox
The cost of a thin diligence is never the fee. It is the re-platform nobody priced, the customer churn that surfaces in month three, the single engineer who holds the system and leaves, and the multiple that quietly caps at exit.
A grounded, code-and-numbers read before signing turns diligence from a formality into the first act of value creation: you buy the right asset, at the right price, with the risks already named.

Common questions
What should diligence cover beyond the financials?
The technology and platform, revenue and pipeline quality, the go-to-market motion, the data and security posture, and key-person risk — the things that decide what happens after close.
Technical or commercial due diligence — which do I need?
Usually both, at different depths. Technical DD reads the platform and the team; commercial DD reads the revenue and the market. This guide covers the operator’s view of each.
How early should diligence start?
Before exclusivity where possible. A fast pre-LOI read surfaces the deal-killers before the clock and the costs run.
