About us

Serious maths, friendly answers

Every drinks brand has to decide what to charge, when to promote and how to handle cost rises. We help you make those calls with evidence from your own sales, explained in plain English and counted in pounds.

What we care about

Answers in pounds

A statistic on its own doesn't help anyone decide. Every result we give comes with what it means for revenue and profit.

Honest about uncertainty

We always show how sure we are. If your data can't support an answer, we tell you that instead of making one up.

Your data stays yours

The free calculator runs on your own computer. For portfolio reports, your data is used for your report only.

How we work

Start small, grow when it's useful

Try the calculator on one product. If the answer is useful, we can do the same across your whole range.

1. Free calculator
One product, your own data, instant answer.
2. Portfolio report
Every product, regional weather, how your products affect each other, and the price moves worth making.
3. Each pricing round
We refresh the numbers before each price change, promotion plan or retailer meeting.

Sam Morgan, founder

Sam has spent years turning sales data into pricing and promotion decisions for consumer brands. datum started from a simple frustration: most price analysis either ignores the weather and the calendar, or hides its answer in a spreadsheet nobody reads. Sam built the tools to fix both, starting with UK drinks.
