## What is Cultural Due Diligence?

**Definition:** **Cultural Due Diligence** is the systematic measurement of organizational compatibility before integration begins. It is the only metric that matters for synergy capture.

70% of acquisitions fail to deliver the promised value. The spreadsheets look great. The strategic fit is perfect. Then you close the deal and the two organisations spend two years fighting over how to run a meeting.

## The Cost of Maturity Debt

- **Integration Friction.** Disconnected tools lead to disconnected teams.
- **Sentiment Slippage.** When the target team feels "conquered," they stop delivering.
- **Governance Gaps.** If you do not audit their compliance culture, you are buying their skeletons.

## M&A Offensive Strategy

1. **Audit Maturity Early.** Do not wait for post-close.
2. **Visualise the Stack.** If their tech is a mess, the price should reflect the cleanup cost.
3. **Track Sentiment.** It is a leading indicator of deal success.
