From data to action. We analyse your performance and turn insights into concrete improvements.

Measuring is only the start. The value comes when it leads to a change that pays off. We turn data into hypotheses, test them, and keep what works.
Booking.com runs well over a thousand experiments at any given moment. The defining principle behind it is not technical but organisational: anyone can run a test, without asking permission first. That speed of learning is worth more than the quality of any single idea.
Most tests are stopped too early. A ten per cent lead after two days means nothing if the volume is too small. We calculate in advance how many visitors are needed and wait for them — even if that means ignoring an attractive interim result.
A test that produces nothing has saved you from a change you would otherwise have made. That is why we document everything, so you don't try the same idea again a year from now.
