# Cultural Due Diligence

Cultural due diligence is the buyer's assessment of how a target actually works — how decisions are made, how people are paid and promoted, how risk and compliance are treated, how the founders lead — against the buyer's own ways, so the integration plan is built on what the two organisations are rather than on their org charts. It is the diligence most often skipped and the one whose absence explains most failed integrations.

**Also known as:** Cultural DD, People due diligence, Organisational due diligence

## Key facts

- **Used at:** any acquisition where the target's people are part of what is being bought — a fintech's engineers, its compliance team, its founders — and any deal between a bank and a startup, where the cultures are furthest apart
- **Binding:** no — an internal assessment, usually by the buyer's HR and integration leads with or without consultants; its findings go into the retention plan and the integration design
- **Typical scope:** leadership style and decision rights; pay structures (equity, bonuses, bands) against the buyer's; hiring and attrition; how the target handles incidents, audits and regulators; engineering practices; the informal networks — who actually runs things; what the staff expect from a sale
- **Typical method:** interviews with the top 20–30 people, engagement and attrition data, a review of incidents and how they were handled, and a comparison against the buyer's own culture, honestly described
- **Parties:** the buyer's integration team, the target's leadership and key staff, and the seller, who controls access

## How cultural due diligence works in practice

A bank buying a fintech is buying 200 people who chose to work at a fintech: flatter, faster, paid partly in equity that the sale will cash out, used to shipping weekly and to founders who decide in a meeting. The bank runs on committees, bands, annual releases and a compliance function with a veto. Neither is wrong; the question is what happens when the second owns the first. Cultural diligence answers it by looking: interviewing the fintech's leaders about how decisions get made, reading its incident log to see how it treats risk, comparing its pay bands and equity with what the bank can offer, and asking the engineers what would make them leave.

The findings shape three things. The retention plan: who matters, what they will lose in the sale, and what will keep them for two years. The integration design: which of the target's practices to keep — often the engineering cadence — and which of the buyer's to impose from day one — usually the compliance ones. And the price, occasionally: a target whose culture treats risk as a nuisance is a regulatory problem the buyer will pay to fix.

The honest part is the buyer's own description of itself. A bank that believes it is agile will design an integration that assumes the fintech's people will be happy in a committee.

## Example

A bank's cultural diligence on a lending fintech interviews 25 people and finds: decisions made by two founders in a daily stand-up; engineers paid 15% below the bank's band but holding options worth two to four years' salary at the sale price; a compliance team of four who report to the COO and describe the regulator as "manageable"; attrition of 8% a year; and a shared expectation that the bank will "slow everything down". The integration plan changes: the founders get a two-year retention package and a defined authority to decide within limits; engineers get retention grants vesting over two years to replace the cashed-out options; compliance is moved under the bank's chief compliance officer on day one, with the fintech's head kept as deputy; and the release cadence is left alone for a year. Attrition in the first year is 11%, against the 30% the bank's last fintech acquisition lost. The diligence cost €40,000 of consultants' time and six days of the integration lead's.

## Common mistakes

- Assuming the target's culture is the founders' personalities, and that retention packages solve it.
- Cashing out the equity that kept the engineers and offering the buyer's salary bands in its place.
- Imposing the buyer's decision process on day one and wondering why nothing ships.
- Describing the buyer's own culture as it wishes it were.
- Treating a target that treats risk casually as a cultural quirk rather than a regulatory liability.
