Data driven UX in the dark


At we are running thousands of A/B tests on a daily basis for over 13 years now. A data-driven approach is great but following the data blindly will not get you anywhere close to success.

Let’s talk about big learnings when designing interfaces for 43 languages and 50 currencies. Let’s talk about optimizing for conversion VS win new markets.

There is a time that the data needs to be left aside and we should listen to our customers.
