Principal Investments

Our own capital, in a small number of businesses we understand.


How we invest

Principal investment means Crystal Zest or group resources are committed directly. That shapes how we behave: we take fewer positions, we spend longer on diligence, and we expect to be involved after the money goes in.

We are usually more interested in a business with an understandable model and an obvious operational gap than in a business that requires a market to move in its favour.

What happens after an investment

Reporting discipline first: a monthly pack, a small set of KPIs and a clear cash view. Then the two or three operational changes that formed the basis of the investment case, with named owners and dates.

Start a confidential conversation

Whether you are preparing to sell, looking to acquire, raising capital or trying to lift the value of a business you already own, the first step is a short, confidential discussion about the situation.
